Hello all

I am new to CNC having acquired a 3 axis woodworking router earlier this year. I have appreciated having access to so much information and experience through CNCZONE, and have become productive fairly quickly as a result.

Having thoroughly researched the local market before buying, I know that there is extensive use of CNC technology in South Africa, from wood and metalworking to laser to plasma to stone engraving. I find it strange that there seems not to have been any activity on this club forum.

I am running a Chinese machine with Chinese sourced software, and so far, both have proved extremely reliable and user friendly. I would be happy to share my limited experience with anyone who is interested, both locally and the wider CNC community.

Come on, guys...:stickpoke Let's start contributing

HI crixnix i also acquired a chinese cnc plasma cutter been in a box now for 7 months only starting with it now runs on fastcam stuggling with the dxf files but would like to be part of the cnc south african community i am in the vaal triangle let see if we can set up something regards SPECTRONICS

Hi sjnelcumberland

I would be happy to help in any way I can. Are you having trouble creating DXF files? Do you need to convert other formats to DXF files? There is plenty of software out there, and some of it is freeware.

I am not sure what the reference to SPECTRONICS is about either. Please explain.

all the best

Hi - I am here and been here a while, I have found that SA based cnc operators cry too much about the cost of setting the machine up (even if i have the dxf or similiar file.....) they dont understand the flexibility a small business needs, they want production runs of 10000 of units and i just want one intercooler flange, enough whining

I am based in Johannesburg running a specialised motor vehicle and performance workshop - my cnc needs are typically mild steel and ally based for flanges, fittings, couplings and mounting brackets etc - I normally draw on autocad and email and then have my local ally supply store do the easy part ! I am dying to do it in house and will probably go the diy route, so i am keen on any group buys etc to save on shipping to SA etc

Hi 3barboost

good to know there are others out there in the void. I tried to build a budget machine, making everything myself including the linear bearings. I learned a great deal, but realised that to do it properly and build one using imported bearings, racks, motors and control electronics was not going to save me anything over a Chinese machine, which used the same parts.

I agree about SA CNC operators. I think that because it is relatively new technology here and that machines cost so much to import in the past, the mindset is to find one job that pays and keep cranking it out. Personally, I would jump at the chance to do one or two things different with my day, but, in general, there seems to be limited imagination here. And as for the cost of setting up the machine - I think that is often just a poor excuse for being unable to think outside the box.

I would encourage you to get or make your own machine. In your business it will make a massive contribution. What I have found is that at first, it is a bit daunting, and somehow different, but as time goes on it just becomes another tool which contributes to the way you plan and imagine the future.

yip agreed 100%
however as a small workshop our bills may be high but retained margin isnt so buying a machine will take a while, but we working on it

i know what an impact it will have ! i cant wait

Hi there crixnix, I am from Pretoria and run haas cnc machines. I have also started learning how to use the components in other machines. I posted a thread regarding the cnc club that runs every first thursday of the month. I got a great deal of info there. The Prof that runs the club must be one of the most competent people I know and he shares our interest. As for the spares you need: a company based in Edenvale called cnc direct can supply the ballscrews, linear guides and stepper or servo drives. Greg also helped me setup my computer with the software and the guys at the club helped me to calibrate and set the soft limits. If you are thinking of building your own machine, you would get the help you need from them.

The South Africans who would benefit from CNCZone and should be posting here are usually not allowed to by their bosses!

In the SA engineering comunity the internet is seen as toy and not a resource.

Hi i have been to china a few times and there is now way you you will build a small machine for what you can get it imported for but only if you import yourself the problem here in sa is the forwarders want to make 50% on what you import i found that it cost me 1000% more to get it from durban to jhb than from shangai to jhb the problem in china is to get the real deal there there is many scams there i have set up a agent there and she handles the stuff there before i pay annything so i did not yet lose money there the machine i have now cut 1.5 meters x2.5meters and with importing cost 3000us plasma to 16mm tortch to 250mm Can someboddy give me the clubhouse deatails thanks

Hi All,

I am new here and have recently build my own cnc machine, using a STD router. It works ok, but not as good as a bought machine. I see you mention an import from china at about 3,000 US? Can you give me more details? I would be keen to get one at that price and size. I need it to cut 1.2m x2.4m.

Thanks!

Hi All

Great to see more activity.

sjnelcumberland did you come right with your DXF problems?

I would love to be part of the Gauteng club, but it is a bit far fron the Eastern Cape.

The offer still stands for help and advice - the little I have learned so far.

My machine uses a R0501 DSP controller, which I know some people don't like. This is a hand-help controller, which incorporates the jog buttons, but which reads the g-code off a USB flash drive. I managed to "brick" it on the 2nd day I had the machine - wiped the memory clean, and had a steep learning curve getting it all set up again, with very little info available on the web, but it now holds no fear for me. I just know that the one thing you must not do with the controller is drop it.

I run a factory making musical instruments, and the machine is already earning its keep doing a lot of the grunt work - without days off and with 100% accuracy and consistancy. I plan to get into making guitars and other string instruments, using the router for sound boards, necks, inlays, solid bodies, arch tops etc.

I am slowly exploring 3D design - the chinese software I am using is actually quite good, being able to import IGES and STL files, but also having a very powerful built-in 3D design capability.


I am also involved in aviation, and have already successfully machined a propellor - although just for display so far. There is a definite possibility that the machine will help me build my own aircraft one of these days.

I will try to post pictures of interesting projects if they come up.

Cheers

Hi Everyone
I have heard of Prof Rudy in PTA area and he sounds like a really sorted and top rate guy and what he brings into the local cnc community are some serious foot steps to follow in, as for building machines I started with a little 3d router then found Greg Paxton from CNC Direct and hav'nt looked back, ball screws, linear guides stepper motors, servo motors, breakout boards, Gecko Drives and machine grade HF spindels. With new resources and parts built a machine for shaping surfboards and a plasma cutter 3m x 1.5m cutting area( machine is a bit bigger) this machine was built with view in mind that the machine could also work as a router bu swoping out the z axis for router work and a extra work surface installed. So climb in and have "fun" and it is really great now havingthis forum for local births( new machines ) and swapping ideas and happenings. I am running Mach3, Deskcnc, Sheetcam, zwcad 3d so if can help or assit along the way ask. As this forum grows so will all the locally built machines. In all fun by all so post the questions get less grey hair and enjoy what will I hope be a growing online CNC community, and many thanks to the originator of this forum 10/10 to you.

HI there quentinb you talking about a router that is more expensive i did import a portable cnc plasma cutter so this have less hardware in than a gantry type but if i can help you i have a agent in china that will make sure that you dont lose money i might be importing 2 3.8 x 6m ganty plasma machines soon so if you need something i can load that in the container for you it will save you some money but think you must go the mack 3 way it looks good software about 165usd interface card about the same regards

@sjnelcumberland

Thanks for the feedback. I currently use Mach3 as the control software for my machine. I use cut2d for generating the tool paths and find it very easy to use. I also use draftIT pro for CAD as it suite my needs nicely.

It would be Great to share a container and help reduce the import costs!

I am from Vryheid in Natal.

I have been interested in cnc for quite some time. However it's only been the last few months that I have really started doing research. I agree, cnc is still relatively new and still expensive in SA, especially for the hobbyist.

I'm happy to see that prices are dropping, and it's something I something I really want.

I am planning on starting to build my own CNC router in December when I get my bonus, but am not sure if I should import a kit or just import the stepper motors ans electronics etc.

I do have a few plans, but I am still planning on table size, as I would hate to spend all that money, just to find in a while that I'm limited by size.

On the other hand, I'm totally new to cnc, so I still have to learn everything, including CAM/CAD. So maybe I should just build a small machine and learn the in's and out's first.

Maybe if and when I do need a larger machine I can convert the older one to a 3D printer.

Any comments/suggestions would be greatly appreciated

Hello all SA'ners. I recieved an email from Bertie that the meeting for the first thursday was cancelled. Sorry. Prof Rudy had an operation but is recovering quickly. Next months meeting should be interesting with some new projects proposed and completed ones shown. I plan on making a 4 axis double chuck lathe to produce small parts. If time permits I would like to go through the basic functions and listen to suggestions you might have.
Hope to see some of you there.

Hi gents (and ladies?)

I've been playing with CNC stuff for a few years now. We used a 4x8 Sabre at the boatyard a few years ago, and these machines are just so versatile. I had to have one.
I ended up building a 4x8 for my garage, and boy what a learning curve.

So now there is a machine run with steppers, and using Mach 3 for control.I use Alibre for cad and cam, it works fantastically well.
I often program our cnc's at work using Pro-Manufacture ( Wildfire) and Alibre does the simple stuff as well. ( It represent a ninety percent capability of what most users will require in their work.)

My machine is as cheap as they come. You can call me mr cheap if you need to.

Think gate rollers for linear rolling elements, and a length of angle iron for a guide.
I achieve 0.5mm accuracy everywhere on the table. I know this is not fantastic, but it gets the work done.

I needed to get going, so this was the way to go.

I struggled with the Z-axis, which works a lot harder than one would expect.

The latest incarnation works exceptionally well, and took me about a day to put together.

The largest problems at the moment remain dust supression, and the spindle.

I have been toying with ideas around a homemade spindle, it is not going to be straightforward.
I currently use a cheap (there we go again) chinese router as spindle.

There are three carcasses lying in the garage.

The best one lasted several hundred hours, the worst one several minutes.

I include some pics of the latest project off the machine.

There-in lies the rub. Having a machine is one thing. Doing something with it that will generate revenue is quite another. ( die hond sit met die kar se bumper in sy bek, wat nou?)

Most people can not afford to spend several thousand rands on a whimsy that will just be played with. So my personal challenge is to make some products with my machine, and use some of the income to bootstrap the machine up to something really respectable. The hard work is done, the controlling and programming etc is all sorted out.
I'm working on a range of flatpack kids furniture, as seen on the pics.

What do you think of this idea?

Regards,

Dries Laas

Hello Dries
Interesting design you have come up with, gate wheels could do the job, I know. (have used them for a whole lot of apps) I think the flatpack kids furniture could work, just make sure to use good quality wood. Try approaching toy-zone or baby city first, they are not as sticky as the rest.
If you are based in the Pretoria area, you are more than welcome to attend a club meeting.
Cheers

Welcome Drieslaas
I have major respect for your achievements. I have some idea, as I tried myself. I also considered using gate rollers for the linnear bearings, but started with a smaller machine so constructed my own.

My decision to buy new was because I already had a heap of work lined up for the machine, and 2 of my staff retired, so the machine could pick up the slack. I am also very pleased with the vacum hold down, and the dust capture, which were all part of the deal with the Chinese machine.

I like your kids furniture designs, but I would suggest decorating them in some way. Cut sillouettes or engrave Horses, Cats, Dogs, Dinosaurs, Aircraft, Cars, Monster trucks etc into the backs. Kids would not normally go shopping for a chair, but if they can fit into imaginary games - could become seat in an aircraft, spaceship or saddle for a horse - they might have more appeal. My 2c worth.

Good day.
i,am from pretoria and loves cnc machines.i got lathes and milling machines at home but use them 90% of the time to build my hobby, electronics and cnc machines.My first machine used angle iron and custom alluminium wheels with bearings inside for the slides and still uses it today for my 100% custom build plasma cutter.Currently i am busy developing dc servo drives but takes up a lot of time .My new machine uses linear slides bought from bearing international for a reasonable price compared to other suppliers.I build myself a laser but after testing it i trashed it because of safety aspects 'very dangerous because of revlections etc"RS components stock good servo and steppers for good prices ,check out their webside.Ok enough of myself my question is is there anyone staying in pretoria which will like to meet and got the same passion about electronics and cnc machines?

Update,

There always seem to be a pesky know it all radio control modeller type person around when you need them least :D. In an attempt to answer a question to one of these exalted beings, I embarked on the next little adventure:

I tried cutting 3mm balsa using a HSS 2mm slotdrill at 30000rpm. The cutter did not even realise the balsa was there. Very chuffed.
Also interesting was the route to reach the toolpaths. I hand-sketched the shapes, scanned to bmp, converted from raster to vector, did a very precursory clean-up of the dxf in draftsight, and imported into alibre for the cam work. Sounds complicated but took a few minutes because all the steps worked.

Have a look at draftsight by the way. It is from dassault systemes, a completely free update of the old dwg editor, and works magically for 2d stuff, which is something without which any cnc router operator cannot get along.

By the way, I also cut just into the surface of a 6082-t6 alum plate with the same cutter to see what it would do, and the results warrant further investigation. Nice diversion.

Hello Jancu.
To answer your question. Yes, the next meeting should be on the sixth of October. I am sure all would like to know more about your laser cnc. If all goes well we should have the sceleton of a four axis cnc lathe at the meeting, and if time permits Prof Rudy would go through the setup of the stepper drives, calibration etc. Hope to see you there.
@Crixnix, I really like your idea of the sillouettes.
@Dries and Loffie. Hope to see you at the next meeting.

Hello guys :)

Im from pretoria-N and been Bitten by the CnC bug also ...hehe Ive been looking into building my own desktop cnc mill for a while now. Ive already ordered most of my parts and just waiting with baited breath for it to arrive. Any1 know how much it costs to laser cnc 25mm steel plate ? ^__^ Wana make it a very rigid & heavy machine as i wana mill alu. primarly & use it 2 build my larger cnc in time. ( 3 axis with a 4/5 axis attachment on table.) *Gulps*

Well also, 10 thumbs up for starting this S.A thread. Now i dont feel so alone anymore. Ill probably start a building thread asap when i got all my things. Btw...if you need ballscrew type shafts...try finding old elec. garage door rails. Got my self a 16mm 2.3m lenth in one and a 20mm in another ...lol alot cheaper to buy them new. got mine for free. Also ....build yourself some furnaces and melt down your own alu to cast & build your own machine. alot of fUn. Well im rambling here.....Its great to meet all of you and hope this thread will stay alive for years 2 come.

Have a Good day guys :D

Hello guys

Got most of my materials today :) So ill be starting my build on my 1.5m x 2m build 2morow. :boxing:

Cant believe how expensive alu. is these days, my gantry, Z-axis & side supports is gona be made out of 20mm 6082 alu. & 76mm steel square tubing for the frame. Just wish they cutted my alu. abit more square (wrong).

Got 425 oz steppers, Gecko g540 for electronics & 20mm linears for all axis's.
Will order my 2.2kw spindle in 3 weeks or so....any1 maybe know where i can look for a Vfd 2.2kw ? One that doesnt cost the earth. lol

Just hope it will be rigid enough to handel milling of alu.

Btw...Any1 else here build there own CnC yet ?

@fransfourie

Welcome!

I've build one and am now starting a rebuild. The first machine was build using MDF and works pretty well. The alu I used for the rails with V-Groove bearings are wearing alot more than I would like and is causing some play on the gantry and Z-axis.

I am getting my new parts from Greg @ CNC Direct in JHB.

You must send some pics of your build!

@Quentinb

Thank you very much. Ill post some pictures soon. Just did a test fit "stacking it loose." the gantry + z-axis. I found out i need 2 get my alu. squared out more somehow >.< So ill first take all the parts 2 some 1 who could square it out to a Fine degree, before i continue. wana do it once. hehe As the saying goes....Measure twice, cut once.

Mind uploading pics of your builds ? ^__^. Might give me some extra inspirations.

BTW....why not import some 20mm linear round shaft blocks into the country?
Cost me aroun R1400 delivered for 8 x 20mm linear sliding blocks. Bought some high grade 20mm round shaft (R370 for 6m) and it floats like a butter-fly..Stings like a bee. lol

If you dont mind me asking, you maybe know where i can get a 2.2kw Vfd locally? Or what makes are supported in south africa. Would be much appriciated.

Well...Nice meeting you :banana:

Where did you get the round bar/shaft from?

I have thought about using it, but worry that with a big machine it would deflect to much over the length. I want to build a 2.5m x 1.5 machine and wanted to use the round shaft. I also thought about the C style bearings with the mounted round shaft but the whole unit makes it very "high" in terms of the shaft and mounting + the bearing added to it.

my current machine....p

Heya m8

a Nice machine you got there :D

I got the round bar at alert steel. It is sitting abit high...2 sec..measering fast...+\- 60mm from top of the block to the bottom of the support bar for the shaft.

The linear block dimensions are H:37.6mm L:50mm W: 49mm (C - style )

Ill be taking a 20mm flat bar(+\-50mm wide) and mill 2 sides on top down by 5mm(10mm wide centre will be kept at 20mm then take a 20mm ballnose endmill to put a radias on the extruded piece for the rail to lay in. dont know yet if ill get it co2'ed or screw it to the plate. this should keep it nice and strait. Well once i do it, ill let you know if it works. Cant see why it wont.
But first im trying to find some1 in pretoria that can square out my alu. with a waterjet cnc.
Ive added a drawing to show what i mean.

Guess you can also make small shaft supports by drilling into say a block of alu with a 20mm dia drill bit & then sawing it in half then space it through the whole length of the shaft for support. example you have a 1m length of shaft. make support blocks for every 200 mm. Draw a line on your gantry with a vinear, drill & tap? them for you support blocks. Should work also.

Btw...What controllor you using ? stepper sizes etc. ?

Well speak to you soon again:)

Quentinb.....Because of you i changed my table also to a 1.5 x 2.5 table xD
Need to go buy 76x76 square tubing this week and guess ill start building the framework the weekend.
Any1 know of a place in pretoria that sells rack & pinions ? very fine teeth??

I imported the bearings from the US. I tried all the bearing places locally and nobody could help! Have a look on buildyourcnc.com for some parts and ideas. If you like, I can assist you as I have a contact there - depends how many you need, I have some spare though...

@fransfourie

"What controllor you using ? stepper sizes etc. ?"
I am using the motor and drivers from the above site. I bought a "Combo" that has all the required goodies to make it work. then I am using Mach3 for the control side of things along with Cut2D for the toolpathing.

Hi guys
I'm looking to start my own cnc wood router, just a small 1mx600mm to start with, and have seen allot of great parts online and I'm just wondering: Does anyone know anything about import taxes and levies ? and where to find out what they will be before i buy things overseas?

fransfourie
09-30-2011, 03:31 AM
@ Draco

Heya m8. Welcome to the S.A thread:cheers:. Where are you from ?
It's alot of fUn building these machines & you learn alot along the way.

For importing of parts, i bought all my stuff via e-bay. I havent payed tax/levies yet on any part ive imported. Just ask them to send as low value items / samples. also pay the extra shipping costs for fedex, aramex, dhl etc. alot faster lol.
Im still waiting for some of my parts 2 get here. if you get taxed, as far as i know it is 10% of the value + 14% tax ontop of that. So...for example you bought an item of 100$...add 10% on that + 14% tax = $125. On cars & things like that its 65% of value xD.

Well hope this info helps. ask away if you got qstions :argue:

@ Lord Draco
Hello there.
Before you start importing, consider the SA suppliers. Not that I am punting them, but I bought the parts for a four axis system from Greg @ CNC direct. After the parts were assembled it took about half an hour before the system was working and calibrated etc.
It really helps to get the right stuff with the backup.
Best of luck with your project, let us know how it goes.
Cheers

Hi All,

Sorry, I have been busy... building my new machine. I have had to wait some time to get the guys to cut the parts for me, but I have them all now and have assembled most of the machine. It is currently in a moving state and need to add some small parts to secure the drive train and fire this beast up!

I'll post some pics soon!

Hi All,

I’m from Capetown, Northern suburbs, Durbanville.

I’ve been doing allot of reading about cnc plasma the past 2 months and I got a few quotes from local companies for cnc setup and honestly the prices are way out of my league, like I’ve said I’m a newbie and don’t know much about cnc but I can weld do design on Cad/Inventor. I did allot of research regarding diy cnc plasma setup and I know about CNCDirect a local supplier of diy components and electronics however for some reason I still think one can get parts cheaper when importing it yourself? Have a look at these links www.candcnc.com (http://www.candcnc.com/) & www.precisionplasmallc.com (http://www.precisionplasmallc.com/) & http://www.cnczone.com/forums/precision_plasma/111498-precision_plasma_llc_history.html (http://www.cnczone.com/forums/precision_plasma/111498-precision_plasma_llc_history.html) I like these options and I think for an diy person this is a very nice setup to start off with.
I was thinking about source for an local supplier or manufacturing company that would be able to supply me with cheap parts like v-groove bearings alu rails etc anybody know who I can contact? I’m planning to design my own cnc plasma table and let all the parts be locally machined but I’m almost guaranteed that it will not be cost effective to do it that way correct me if I’m wrong. At the moment I don’t really have an budget still need to save-up but my goal is to have an table with 2.5x1.3 cutting area with Hypertherm 45/65 plasma cutter and DTHC and try to keep my budget under R50k….going to be difficult but I’m up for the challenge.

I really hope some local people can contribute and guide me in the right direction?

Local is lekker!

Hello guys:
I kwon the wood cutting machine is very hot in South Africa, and Many friend purcahse the machine form me, usually I sold them the GSI200W and GSI280w to them, and they will use the machine with Chinese laser 300w, too. maybe sometimes the Rofine. I think It is great. but I do not like the machine with chinese laser 300w. because it is worse than GSI and Rofine! thought it is cheaper. How about your machine, what is the machine do you use, can you tell me?

WOW thought i was all alone here!!

Im from Cape Town and looking into building a cheap as possible wood mill!! Well so far cheap is not the word! Looking into a 10X9 similar to the Solsylva...

Hoe have you guys found building your own machines?

Yeah you would think DIY means cheaper from yeah certainly not in this case! Well cheaper than store bought but not sure by how much...

Im looking for a wood mill, 250 X 250 would be what i want but close enough is good enough... Not really interested in plasma...

How about the laser cutting machine, Do you know this kind of machine?
I think it is a good choice for you, but what is your materials, and what the 250X250? mm or feet?
You can have a search on youtube caspergeng, I uploade many videos on it.

Hello guys...its been a little (nuts) the past months.. hehe

Been a while since ive been online....had some copper theft /sigh
Anyhowz....here are some updates of my build so far.

Still need to make a new plate for my z-axis but works fine for now :)
z-axis & x -axis movements are accurate to 0.02mm for the moment.

Any updates on your builds ?:banana:

Awesome work there frans!!! love the castings you have done! whats your raw material for that? old soda tins?

your machine build is really looking great man! may i ask what linear bearings you are using? Did you import the motors?

Dont use soda cans as it gives of poisen gases + you get more dross then usable material. I buy alu of scrapyards for 20 bucks a kg also from old brooms, door/windows, engin blocks...etc. Gona start or rather try melting steel soon. Doing 1350c +/- atm. Need 1500. :) got the bearings of ebay name: sbr20 uu I think. Just search ebay ....sbr20. Cost me around 1400 for 12 bearings. Costs 400 to 650 for 1 here in Sa. Lol. Got the motors also on ebay, though if you go back in this thread, some1 responded to my qstion about rack & pinions. That place he mentions has very good prices on motors
and other related cnc parts. Got any pics on your build/design? :)

I see you got alot of your stufff from ebay! what was the shipping charges like? Most times the shipping charges make the cost of the product similar to local costs.

:) May i ask what kind of furnace you using? Is it coal or gas? If you move to steel what kind of crucibal would you use. Cause for Alu they say use a steel one cause its melting temp is higher than Alu.

Thanks for the heads up on the bearings and motors, will do more checking to see what the costs are.

I havent taken a single pic to be honest, at the moment its alot of trial and error. Trying to figure what works and what doesnt and what kind of products are available to us here in SA. Im going for a fixed gantry design and using skate bearings with angle alu for the track and truck...

wil l take some pics and post up...

Heya Megeshg
You cant even compare it to south african prices...as you get totaly ripped of here. For postage it is'nt that bad, if you dont mind waiting it takes average 2 - 4 weeks for stnd'intl postage and about 1 week for dhl...etc though you pay for it :) For import duties i payed R70 on 1 item and about R40 on another, rest i didnt pay a cent. Those 2 items i had 2 pickup at the post office as it was stnd intl postage, the other items was through carriers and didnt pay any import duty on them and was dropped at my front door. :)) so it is worth paying that extra $$$ When you place an order just tell the person you buying of ebay to send it as a low cost item.

Concerning Smelting.
Ive build my furnace out of a old water pressure tank and lined it with about 100mm "35kpa" cement mix then lined it with a very fine layer (3 layers) of bentonite mixed with 250 mesh sand. I use used motor oil as it burns alot hotter. ill be selling these on e-bay soon :) for around R700 in our money. can use gas-unleaded, diesal, vegi oil or motor oil as fuel. Ill post a video when i get time. I use potjie kos pots for smelting my alu in. i do about 10kg at most in 1 go and takes me around 10 min to start the furnace(getting the temperature up) and another 15 min to smelt it. For steel ill be using a specialized crucibal, they go for around R600 bucks imported. its of an composite nature if i remember correctly. alu melting point is 750 ish and 1500 +\- for iron. You do smelting aswell ?

I can bet you now that you wont find thoses bearing cheaper anywhere else then e-bay. for the stepper motors, as i mentioned before that 1 place has decent prices if you dont wana wait 2 - 3weeks.

Upload those pics m8 :) trial & error pics are also good :)) ask & you shall receive ^^. building these machines are Great FuN and wont trade the experience for anything.....well maybe for a few million buck's *hint, hint* lol

Anywayz nice meeting you and Welcome to the Community :)

I dont want to get into how bad industries are at ripping us a new one when it comes to specialised low volume products here in this country, then there is the lack of knowledge on some peoples part that makes you wonder how can they even think of selling the product!!

Many people have recommended E-Bay, i guess i must just take the plunge someday. Since right now im doing a desktop unit, when i move over to a full sized unit with a moving gantry then i will consider some really nifty parts from E-Bay!

Nice ideas there!!, what does the 35KPA actually mean? thats a pressure reading so how does it translate into how much temprture it can handle before going kaboom!! WOW awesome idea man!! You need to keep me in the loop when you start selling those units! if only you were in CPT i would have come by and gotten one! LOL love the potjie idea, that must work a charm! Keep me in the loop regarding your steel experiments will be very interested to hear how that goes!

Currently researching and looking at what i could do if i started the smelting route, just the issue right now is that my wife is on my back regarding this current project. And now there is a new born and time is really slim!!! Thinking of getting the CNC completed then moving into smelting and then maybe a rebuild "bigger and better"

Gratz on the New born :) Ill def. keep updates commming once i got some things sorted out.

Any one out there now of some one that wants to sell an old milling machine ? ^^ 800x240 table in a decent condition. >? Wana convert it 2 CnC also ^^ for doing small steel work. Cheap as Possible xD ....was thinking of getting the 45mm geared mill from adendorfs but really want a belt driven machine so i can pop a 4hp motor onto it with a new vfd.

Hei Frans,
Goed om van jou te hoor :)

Ek moet nog 'n begin maak!....maar, nie te sleg nie, more koop ek my Optimum BF46 Vario in Melbourne, sal hom omskakel na CNC, en dan begin met 'n kleinerige CNC router om PCB's te vervaardig, en vir algemene ligte werk.

Trek binne 2 weke in my eie huis in, uiteindelik, aangesien huise hier baie duurder as as in RSA. Moes 6 jaar wag, maar bouer is amper klaar. Nou gaan ek 'n lekker groot motorhuis he, en natuurlik plek vir die BF 46, en 'n CNC router - heerlik.

Sal kort-kort hier inloer, en jou gedagtes steel, hoop nie jy gee om nie.

Groete daar, praat weer later :)

Heya guys

My telphone cables has been stolen so many times, telkom refuses to repalce the lines anymore as such, the only internet access i can get is with 1 of those dongles. Suffice to say its really expensive compared 2 adsl :mad:

well....Enough complaining. How is every1 doing ? any Updates ? Ill be getting my 20mm shafts soon from China. O ye...im looking onto importing larger quinty's of it 2 south africa. would anyone be intressted ?

20mm Sbr supported rails. they cost around R1000 to R1300 per meter here in south africa. Im checking in to a few things but should be able to sell them for around R700 per meter. maybe less.

Let me know

Kind Regards

Hi Im from Welgelegen, Cape Town.

Nice to see some fellow South Africans on this forum.

Im in the process of building a 40W CO2 cnc laser cutter its about 95% done, I had a 1220 x 610mm homebuilt CNC router but sold it to fund the laser build.
You can check my buildlog at buildlog.net &bull; View topic - Edmond's Buildlog.net Laser Build in SA (http://www.buildlog.net/forum/viewtopic.php?f=16&t=409&start=70)

I imported most of the parts for the laser, tube,bearings,electronics etc.

I have a good local source of s/h but tested stepper motors, I paid R20 each for nice Nema 17 steppers, the guy has some nice Nema 23 steppers at R150 ea, the guy is based in Plattekloof, Cape Town.

Hi I have been lurking around the zone for a number of years now I live in Durban but work overseas so time for building machines is valuable.

To date I have built a desktop router first out of MDF then redid it in 16mm aliminum plate and have modified it a number of times and have more plans for it.

I also got my self a RF45 clone and have CNC'd that the Z has a ball screw X and Y still got the origional lead screws works pretty well so far, still lots of tweaking to do.

I am also busy with a small desktop router made out of PVC which I want to produce for sale just trying to keep the price reasonable so more people can afford it.

I have an emco lathe I bought as scrap and CNC'd that ball screws and a three phase motor and VFD.

I use Mach3 for all and various stepper drivers the mill and Lathe have Gecko 203V's the router has some drivers I picked up in Shanghi when I was there they work really well. The plastic router is using a 3axis Xylotex driver.

Last week I recieved some drivers I founf on ebay for $9.99 each they have the Toshiba TB6560 chip and seem to work nice smooth so in future I might use them for the plastic router.

Most of my stuff I get off ebay, the Geckos I get directly from Gecko(great service and quick) breakout boards I get from Homan designs Australia.

Computers I buy by the kilogram from recyclers they get them by the pallet load nothing fancy but fine for Mach3 and they have parallel ports.

I will try put up some picks I am having no sucess at that yet.

Keith.

Nice to know someone from Durban is doing this. I am principally a designer and prototyper for a wide range of products and would be most keen on seeing your machines and maybe trade some ideas.

I would also be very interested in purchasing your desktop router.

By the way have you considered building a 5 axis router, is it even possible?

PM me if you would be happy to let me drop by

Hello guys.
Its been a while since my last time here ^__^ my machine is running now and pumping out wood clocks and signs for a start. Ill post some pics later on, its not a looker though lol. but money has dried up ;p.....will finish it once i get some money in. accurate to about .1mm atm with my shoddy garage door lead screws :) More then good enough for wood work:rolleyes:

Will be upgrading it 2 helix 1.5 / 1 module on x/y...ballscrew on z...
and a 3kw flea-bay spindle or might just make my own.

Any new builds going on ? if so post some pics guys. also ill be making a new thread soon where every1 can post the things they cut.

Well...have a good 1 guys

@Quentinb
What you using on x/y axis atm ? specs. and what's ur max cutting speed atm ? im at 2000mm/min atm but aas stated before my accuracy is abit shoddy atm xD but my repeatiblity is spot on atleast. Just sold a few more clocks as i right this post...20 more clocks and ill have some cash again to finish my machine rofl. i had R100 bucks left in my bank account once i finished my machine, with no income. But hey....i made it through the worst of it and theres only going Up now :D

Been lurking for a while.:cool:

Has anyone bought a high speed spindle and VFD over Ebay?
If so, what were your experiences?

I've been through the whole route of cheap prototype machine, and I'm now beginning the process of upgrading to a proper build.

For some examples of stuff that came off the John Deere special ( as my sarcastic friends refer to the damn thing), have a look at Index (http://www.cubcraft.co.za) , just please pardon the website. I'm no graphic designer, it is just a prototype site...

There is also a scratch built 2 x 3m plasmacutter in Heidelburg that is now starting to do its' thing. Torch height control, touch-off torch mount and a nice big Hypertherm to top it all off. I'll ask Deon to send me some pictures.

I have a machine I built a few years back still not 100% complete but it works great.
I have a VFD from Ebay 2.2Kw water cooled it works great, but I have always had a problem with pumping the water through the motor. If I was you go for the 3Kw air cooled.

Hi everyone.

I have a Burny 2.5 Plus cnc controller on a Pierce Scorpion 2000 plasma cutter which is faulty and am looking for some replacement parts or another working unit.

Both x & y axis drives are ready but will not move when using the direction buttons or trying to run a program. I have checked the everything up to the controller and it is ok, so I suspect the problem is on the pcb.

Thanks.

Real great to see a bunch of us locals playing with, what must be, the coolest machine any man can have in his garage!

I'm busy putting together a machine of my own, and learning lots as I go along. Hopefully all the bits arrive here from China soon enough so I can start my build.

I am now the official world record holder in changing conventional router bearings. My two "spindles" have worn out to the point where the cutters last longer than the lower bearing....

So the big decision to invest in a proper high speed spindle has been made for me. Off to ebay I go, and it seems there are 2.2kW watercooled spindles with VFD's (Huanyang or something?) for the region of R4000 (ER20 collet, up to 12.7mm diameter tooling)

Does anyone here have any experience with this machine?
How long does it take for stuff to get here from China?

My last E-bay transaction from the USA took an underwhelming eight weeks to get here.

gbyleveldt
11-29-2012, 12:23 PM
I've also been eyeing those same spindles, but the watercooling part puts me off. Having no experience with this whatsoever, why wouldn't you go for an air cooled spindle rather? I'm assuming water would work better as a cooling medium, but does that then mean you should avoid air cooled types?

As a start, I'm going to be using this router for my CNC:
Makita RT0700C Router / Laminate Trimmer with Trimmer Base 240V (RT-0700-C) (http://www.toolstop.co.uk/makita-rt0700c-router-laminate-trimmer-with-trimmer-base-240v-p40020)

What router are you currently using? Sorry for the 50 questions...

As far as shipping from China, I'm pretty sure that they'll have the spindles couriered so it should take at most 2 weeks to arrive.

drieslaas
11-29-2012, 02:19 PM
I like the idea of watercooled. The amount of energy heat)you can remove using water as a coolant is just so much more. I think that the acchilles heel of all high speed spindles is high temperature. The shafts and housing are respectively steel and alum, and when the temp starts increasing, the axial load on the bearings increase tremendously.
From what I can gather, the watercooling is as simple as routing two tubes with your loom, and having a nice large reservoir of water (probably with antifreeze or soluble oil to extend the lifetime) and a small pump. It certainly warrants thought, but nothing a cnc machine builder cannot handle.:cheers:

I would very seriously suggest designing your setup to accept a proper spindle from the start. These brushed motors in the normal hand-held routers are simply not designed to handle the duty cycle you will subject it to when you start executing long toolpaths. I routinely cut for three hours at a time, twice a day....

That laminate trimmer does seem nice though, you dont have to hack it to fit, and can probably replace it once or twice under warranty before someone's moer pluks on the supplier's side.

I love the fact that the swearword filters do not speak afrikaans...

Currently I use a little slice of heaven called a quali-prod router. Chinese and branded locally, it has handled some serious abuse, and I own four spent carcasses now! I keep one as a backup, and cut with the other until the bearings go, Then it is switched out, and the old one gets reconditioned ready for action. Tedious at best, and I can not let the machine work and carry on with something else. Which is one of the largest advantages to a CNC.

By the way, the new website is up:

Ah, I see. The watercooling thing makes sense, thanks for that.

Well, seeing as I'm still undecided about the spindle and because I don't know nearly enough, I'll probably hold off on getting one for now. As a start I'll grab that Makita router and use it for now (it's cheap enough and can be used elsewhere), till I learn more about this stuff. I was going to make a router clamp so that it's easy enough to just remove it and replace with a spindle anyway.

I guess I should probably start a thread of my own rather...

That toolstop website did manage to mess up my evening...Have you bought from them? I'll be getting some bits for a start to see. Very good prices.

You're right of course that little router will make a very useful addition in any event. You still need a handheld router for other jobs.

I'm off to go and find a spindle now.

Hehe, nope. I've not bought from them. Their site was the first one that popped up showing the router. I'm actually getting it from a local outfit here in Benoni (it's a little cheaper and on special - just can't ignore a special!) But as far as routers go, I've got 3 already :D

And stoppit with the spindle now - you gonna make me get one as well! But seriously, let me know how it works out for you because ultimately it's also something I want. I just have to pull back on the spending now as I've already poured R15k into this already and I've not even looked at the frame yet. I'm waiting for all the bits to get here so I can lay it all out and double check sizes before I order the profiles from Cncdirect.

Hi guys,

Just wanted to introduce myself here as this is the "Local is lekka" thread. I live in Durban and keep myself busy with automation / electronics. In the last couple of months I have been doing so much research into this CNC router subject that my head is spinning.

Glad to see that we are starting to get an active community here in SA. Will start posting pics of the design and build process once I get started.

Cheers
Andre

Please do. I've got most of the bits for my project today, so I'm hoping to have my build completed this holiday season as well.

I bought a 1.1 Kw Spindle and a Fiji controller from a company in England and the cost was 561 pounds (about R7800) It is brush less and air cooled. The brushed motors is just to noisy and if you work out of your garage you will have the neighbor at your door. Water cooled spindles have a longer duty cycle

Thanks for that. Yup, I ended up with a proper spindle as well - the router was just too noisy. The spindles work really, really well I must say. I'm very happy I ended up taking the plunge!

I bought a Kress Fme1000 spindle from the guys at cnc solutions after using a Bosch blue router. The Kress is fantastic. Smooth. The Bosch router worked for a while but when the bearings started going it had to get something proper. I looked at the Chinese ones on eBay and they appear to work well from what I have read, but I must say, I am very happy with the Kress. Cost was about R2,000 if I remember correctly.

^^^ It so happens that I've bought a Kress FME-1050 spindle as well. At the time, CNC Solutions didnt have stock so I ended up importing it. As with everything on my machine, I ended up buying double of everything, hehehe...

The unfortunate thing is that I'm not using the Kress at all. In fact, its only got 5 minutes of use and I got it with 4 extra collets and the mounting bracket. Not sure how advertising works here, so rather PM me with an offer if anyone is interested. Twist my arm, its pretty flexible :)

The only thing with the Kress is that I have not yet figured out a way to mount the RPM sensor for my SuperPID speed control (www.SuperPID.com - Super-PID Closed-loop Router Speed Controller (http://www.vhipe.com/product-private/SuperPID.htm)). On the Bosch (BOSCH Palm Router GMR 1) it fitted perfectly and worked really well.

Just to show what that little Makita router can do when you restrict depth of cut compared to what a Spindle would do: I am impressed after shunting one into service while my Spindle gets repaired (motor rotor was attached with a tiny spot of locktite so it's getting a new set of P5 bearings and dynamic balancing). I duct-taped the dust extraction on as the dust-foot attaches to the spindle.


Sonotube Subwoofer Flanges - YouTube (http://youtu.be/R088jmasT5A)

Here a 3-odd mm cut at 12m/min at full tilt. It's no spindle, but it's lowest speed settin makes 6mm ali cutting feasible (no VMC, just handy to make up small adapter plates and rough out larger work for final machining/reaming/similar)

Hi Guys,I am also from limpopo and my current hobby is building custom overbarrel suppressors for rifles. I am however a big fan of custom and laminated riflestocks and Have been looking to get a 3axis cnc router to help me out. Nothing big I need about 1000mm x400mm cutting area so its really not a big machine.I would like to know if it is beter to build the machine myself or import one from china? I would apreciate it if you can point me to a legit seller in this case.
thanx

So the chinese spindle ( someone must teach auto correct that the spelling is SPINDLE and not SPINDEL) and VFD has been lying in a box behind my desk for a few months now. It does look like a pretty sweet machine though.
It has been joined by all the makings for three 3:1 reduction drives (using timing belts and pulleys) and brand new linear guides to cover the 1.3x2.8 meter build I have in mind.
I am actually busy designing the beast and cleaning up the shop in preparation. Now if only I can get the bloody fence built and the inside of the house painted, I can start playing again.

Hi guys! I'm new in the cnc business and in the forum too!
Need little help please!
I have breakout board V5 type from China and is working fine om my plasma table,but i cannot set the pins and ports to trigger the torch!
If any one have the same breakout board and know how to set the ports and pins to trigger the (spindle) torch relay,please let me know!
I did contact the seller ,but hi know nothing about that!
Please help!

dust extraction: the bane of my existence
I have made a few attempts to do this, and it has worked with varying degrees of success
one item which eludes me is the strip brushes to make a proper seal.
I need this to work well because I don't have a lot of power in the extractor (1 hp, 750 watt, high flow - low pressure shop dust extractor)
So I spent some time to get the strip brush right.
Please if anyone knows where to buy the stuff in SA, let us know.
In the meantime, here is my prototype setup:

I also have a Chinese router and laser cutter and I am happy with the performance. I know Greg from Cnc direct as I bought the material for my plasma cutter from him. I imported some stepper motors just recently for a desk top mill that I am building.

I would like to spend more time in the workshop but I am working in West Africa and my workshop time is very limited

I'm a newbie living in Stellenbosch and have been trolling through the various CNC forums. This thread was of interest to me as I have just ordered components from HobbyCNC to build a machine, but the last post was exactly 2 years ago ... did everyone suddenly drop off the planet?

I am also planning to built one (jgro type), i think i will be able to build one but i have to do a lot more research!!

Ja I think the fact that everyone is fighting to survive may be a part of it. Not much time to play.
I started my router recently to blow the dust off the motherboard.......
I am looking at doing a new project, and have been trying to get my head around the arduino based systems.
It just seems inappropriate for cnc control at this point. Next port of call is LinuxCNC, so I will try to keep my experience a bit more updated.
We did do a kick-ass 3d printer in the meantime though. Who knew how slow they are? So hard to see a little squirt of plastic dribbling out, when you are used to cutting MDF at 2000mm/min, and rapid-ing at 10000mm/min....
