Hi ,
I got the plans and manual fromanother link listed and am about to unzip them now.
Thanks:)
Good job, arthurk. :cheers: I knew you could do it. And now... the FUN begins!!! :banana:

Download link -


Fatal error: Call to undefined function: get_lang() in /home/cnczone/public_html/modules/Downloads/viewfile.php on line 70

There is an error in the link to the free plans.
Error in line 70 !!

Okay, I owe you two an apology. I am sorry, you two are correct.

I couldn't figure out how everyone was getting an error or having trouble downloading the plans from all of the links posted by myself and others, BUT, I finally figured it out. It's not from the posts with all of the links, it is from the link in the very first post by CNCadmin.

I have sent CNCadmin a PM asking for his assistance in correcting his download link in the first post of this thread. In the mean time please use the more recent file links posted HERE (http://www.cnczone.com/forums/showpost.php?p=195533&postcount=283).

A BIG THANK YOU to JGRO for all I have learned by building my CNC Router Table from the set of plans he made available on CNCzone.com for FREE. The experience has changed my life in more ways than he will probably ever know.

There was an error for me as well when trying to access the download page

Hello All

I have to shout ME TOO I am afraid I get:
Fatal error: Call to undefined function: get_lang() in /home/cnczone/public_html/modules/Downloads/viewfile.php on line 70

Does that help?

I just used the links in Msg #293, and all downloaded all 3 files perfectly!

BTW.. FINALLY got my machine running good. Made a nice sign for the front of our house.. Which Forum/Topic would you suggest I post it in? I used Bobcad to design, and Mach3 to cut it out, and a JGRO machine to be capable of doing it in the first place *GRIN*

BTW.. on a different topic, it was discussed where the most effort goes when learning this hobby, and I have to say that for me it was in teh CAD/CAM area. I already knew electronics, and didn't have major issues with building the machine, other than making a thrust bearing for each axis, but the CAD area has taken me a year to get to where i could do ANYTHING useful with it .. LOL

Guess I just didn't apply myself enough to learn it like I should have..

What kind of speed are you guys getting with 1/4-20 lead screws?

What kind of speed are you guys getting with 1/4-20 lead screws?

Up to 60 ipm.

Here's my answer with more details that I posted here in another thread (http://www.cnczone.com/forums/showpost.php?p=190934&postcount=4).

Thanks for the info. I have about the same setup, but only get about half that without losing steps. I need to check some things.

What kind of speed are you guys getting with 1/4-20 lead screws?


I can get up to 50IPM, but it took months of fiddling to get everything aligned properly to avoid losing steps before I got to this.. last month it was 25IPM max.. I just got lucky and managed to line everything up right.. *GRIN*

HayTay:

What brand and model stepper motors do you use?

I am looking at specs on mine, and in bipolar mode the torque drops off rapidly with speed -- this could be part of my problem.

rweatherly,

I'm using Japan Servo KP56QM2-001 unipolar stepper motors I pulled from old HP LaserJet II/III/IID/IIID printers. The specs. are available in the attached PDF I put together as a reference sheet. This updated PDF now contains a list of printers where these motors can be scrounged from.

Hay Tay-

I tried to find some torque/speed curves on your motor, but no luck. 60 ipm is 1200 rpm, and I think that's beyond the range of my motors. I am guessing that my high torque steppers are trading torque for speed.

I ordered one like yours off Ebay and will try changing it out instead first instead of looking for other problems. I also went to a 1/2-10 Acme, so now my speed is doubled.

hey can you take these plans and make a bigger table out of it such as a 96x48" table or would you have to change the design

thanks mike

First and foremost... WELCOME TO CNCZone Gerry!

And yep, they sure have. We'll start with the one in this thread designed by JGRO, then there are the several table iterations leading up to Joe2000che's Model 2006 R-2 (who, BTW, started with a JGRO router table), and the LC50 CNC Starter Kit designed by LionClaw, there's also the steel MechMate table design by Gerald Dorrington, plus many others who may want to speak up. The above design plans are all available from the individuals web sites, here on CNCZone, or both... FOR FREE. Joe and LionClaw both produce and sell their designs as kits for a reasonable price.

If you take some time to look around CNCZone you will see all kinds of working tables built from wood, plywood, MDF, acrylic, HDPE, UHMW, aluminum, steel, or some combination of the above construction materials. Your imagination and your wallet are the only limits. Build one from one of the FREE plans, purchase a set of plans, buy an already built table, or use your imagination and skills to make your own.

I don't know your definition of decent, but most of the tables being built have a fairly high degree of accuracy and repeatability. This is despite the fact that they are being built with 'hand tool's and usually some type of wood.

Are you looking for something in particular?

Hi Folks,

I'm really close (like..., tomorrow), to finishing my jgro-inspired router, and am looking for tips to set up the rails properly. I've got them working pretty good, but it's not quite there yet.

I'm sure it's been covered before, but so far my searches haven't turned up anything. Could someone point me to the threads on set up and tuning, please?

Thanks

I am working on one myself. Wish I was done already but life keeps getting in the way so keep making slow progress.

Congratulations on your JGRO table, it sounds like you've hit the home stretch. And a big welcome to CNCZone, too, DaveDavies. We look forward to your additional posts and contributions to the information pool here.

Thanks very much, HayTay - I'll dial it in first thing tomorrow with those instructions.

And thanks for the welcome! I've actually been lurking around CNCZone for a while, but this is all new for me, so I haven't had much to contribute so far. However, I've sure appreciated being to learn from the others while I built the machine.

You're right, I am on the home stretch - it's so close I can hardly stop working on it at night. All I have left, aside from limit switches and tweaking, is the router mount. It's fairly stock..., except for size - I made it 48" X 24", switched the gas pipe out for cold rolled, and poured aluminum adjustment blocks. I'm using Ohmikron's drivers and 276 oz/in bipolars. I'm trying our different software programs - Mach3 seems to be pretty popular.

I think the next step is to build a spindle, so as not to upset the neighbours.

Thanks again

You probably should check out the FREE Plasma Table plans as detailed in these two threads:

Plasma Table Build Log Including Free Plans Link, & Pictures by Weldtutor (http://www.cnczone.com/forums/showthread.php?t=16634)

Free Plasma Table Plans (http://www.cnczone.com/forums/showthread.php?t=14488)

It has the two key words, STEEL and FREE. At a quick glance, the cutting area appears to be approx. 1.25m x 1.5m (49" x 61"), just what you were looking for. Of course you don't have to use the table for PLASMA cutting, just scratch anything that specifically references the PLASMA 'stuff' and make a mount for whatever router or spindle you are considering using. Of course, the plans could be adapted in order to use aluminum plate, angle or 80/20 extrusions instead of all steel.

Don't forget the MechMate (http://www.mechmate.com/) plans for a STEEL table that are also provided for FREE! See the MechMate Downloads (http://www.mechmate.com/downloads.html) section on their website for the plans. I believe the MechMate has a cutting area of at least 4' x 8' (1.22m x 2.44m). I'm sure the bed length can be scaled down to the 1.5m (5') size you're looking for.

Data-Cut (http://www.data-cut.com/router.html) sells plans (99 USD) for a slightly smaller table constructed from precision ground cast ALUMINUM plate and extruded ALUMINUM rail. The cutting area is around 30" x 49" (0.75m x 1.25m). I don't know how easily the Data-Cut design can be scaled up to meet your cutting size requirements. Additional information is provided in Data-Cut's Assembly List/FAQ .RTF document (http://data-cut.com/download/dc-list.rtf).

Gerry, you probably need to move out of the JGRO Router Table Design section and start your own thread. You'll get more information (or more useful information), quicker, and from a larger number of members. I hope this is enough to get you started.

JRGO - thanks for all the selfless hardwork that went into these plans...you are da man! Anyway, I am a complete newbie to CNC stuff and got interested due to another project...I am wanting to build your plans but have a really basic software question. What is good software package at a low cost that will run on a MAC OS X? Everything I've seen is PC/Windows stuff and I don't have a single machine with Windows (or one that will run it). Anybody have any ideas for MAC software to play with while I am working on building a machine?

Thanks,

Will the RotoZip 2 fit the RotoZip 1 mount?

I bet you'll want to after you use it for awhile. :) I wouldn't think you'd have a problem cutting foam at that speed, as there would be basically no load on the spindle.

Sounds like it should work OK, but the power supply might be a bit marginal on the current rating. Might be OK, though.

woodchucker,

A hearty welcome to CNCzone. Take a look around and you'll find all sorts of fantastic plans, ideas, links and esoteric information. Enjoy!

To answer your question and to get you started, here are the links to the JGRO plans in DXF format (http://www.cnczone.com/modules.php?name=Downloads&file=viewarticle&id=24) and the JGRO plans in PDF format (http://www.cnczone.com/modules.php?name=Downloads&file=viewarticle&id=4).

Take your time and wade through the, now almost, 30 pages of this thread and most of your questions will be answered. I know it's a tough job but someone's got to do it. Post any unanswered questions and you'll usually get a fairly quick reply.

Good luck with your build,

My school's CNC (a Techno-Isel) has a travel area of 30.5" x 34". One
of the parts I must cut out for the machine is 41.67" long and others
are very close to 34".

What procedure/method should be used to cut pieces longer than the
travel? Or what other ways are there to fix this problem?

How would you reccommend I go about cutting the parts? I was planning
on using a sacrificial piece of MDF, then laying down a piece of MDF
the size of the travel and then cutting out multiple parts at once.

Any Ideas?

If the piece of wood to be cut is not itself limited by the size of the travel in one axis and the piece can have extra holes could you (1) use the CNC to make a series of inline holes in the sacrificial MDF (say every 6" left to right). (2) move this sacrificial piece 6" (to the left). (3) lay down your part piece and use the same code to cut two or more holes from the sequence as far apart as possible. (4) peg the part to the sacrificial piece using 5/16" dowels and clamps (5) cut the left hand end of the part (6) move the part 6" (12" etc) to the left and re-dowel and clamp. (7) cut the right hand end of the part with the appropriate offset.

The guide holes in the piece part need not go all the way through if that would help.

I really don't know if the G-code can be made to cut half a part i.e. an open cut. Please
understand you have about a 50 year lead on me in this endeavour as my own CNC is still a work in progress.

I just seen this thread and thought I would thank you for the plans. Amazing detail. I have been gathering "stuff" to build it for over a year now. But this year should be it. I think I have everything. Bearings, pipe, wood, steppers, controller (Xylotex), router (or plasma) and computer. I sure that I forgot something, oh yea, TIME. Oh well, I really want it bad, I am sure to find the time. Thanx again,

Where did JGRO go anyway. I agree his drawings and design are great. I built one as a starter machine, and now I'm ready to build a bigger and stronger more modern design.

Still, I wonder where the JGRO inventor went? I've been on this forum for a solid year, and I haven't seen him post, not even once.

All you have to do is a search

Nice work on those dwgs JGRO!, the real issue with do it yourself is the linear hardware, ballscrews are very expensive, least expensive around $2.00 PER INCH!, the linear tracks can run upwards of $3.00 PER INCH. and the linear bearings etc are very expensive also. If you go that route, (using premanufactured linear control hardware) you may as well write off your budget straight away, I mean for a small table, (less than 24" sq) you are probably looking at like $1000 just for the linear hardware! That blows 95% of the DIY budgets. I used this angle w/ 4 bearings attached concept & steel pipe for the rails (saw it from a guy in Austrailia, he used steel square tube) and the cost is still reasonable. This is the way to go for the DIY & for low cost machines. The expense for hardened, ground tracks & complex, v-groove bearings & cable channel etc. etc. is just too expensive, the DIY really needs to take on making those parts as they are the most expensive pieces. This set of plans takes on that challenge & does a good job of it I think. The next challenge is the scale of it, one of this simplicity & cost effectiveness that can handle a 4'x8' sheet of plywood or other material.

Nice work jgro!

btw, my table summary can be seen on my website here: http://www.calvinodesign.com/90037/90037.html

I've not gotten a lot of response in the Zone here about my table design & build & cannot figure out why, thinking it's just because it doesn't use the nice expensive hardware & all of that, that's the best I can think of.

Cheers
--Mike

Well, my best guess would be all the welding that one has to do to complete your design versus the drill and bolt design of JGRO's.

Does anybody know of or have a set of jgro's machine converted to metric? Anywhere to buy parts in Australia would also be appreciated.


Thanks

Hi guys,
About a year ago, I decided to build the JGRO and I'm so glad that I did. I've loved every minute of it and if I don't cut something everyday, I feel a little sad. Anyway, last year, when I evaluated the different designs, it came down to JGRO or the JoeCNC2006. The JGRO drawings were just so detailed, had to build it.

All the while using my JGRO, I've known of it's limitations. Its pretty flexible, and the table will only cut 15x30 max. So, now I'm in the process of improvement. I've started building the Joe4x4Hybrid (http://www.cnczone.com/forums/showthread.php?t=38220). The plans are fantastic, 24 pages of drawings, with dimensions, and parts lists.

The cost of the plans is not free, but I can absolutely say, I'm very impressed by the product. Joe is offering the plans for $75 for the folks who have been waiting for 5 months, then he's going to raise the price. I can tell you that Joe has put hundreds of hours into designing and drafting these plans.

Check it out.

Again, this design is buildable with a table saw and router for the wood, and a metal cutting saber saw for the uni-struts. All parts are completely dimensioned too. No welding. The cutting table is 4 foot by 4 foot. That's impressive.
Good luck with your builds, what ever you choose. This hobby is very addicting.

If this is not the right place for this please let me know!

But I'm looking to get into CAM with a CNC router and was wondering if someone on the forum had built a router based on JGRO's specifications? Would it be unreasonable to offer $200 (plus parts and shipping) to build one of these for me (and others on the forum I presume)?

I've one built already, and have all the pieces cut to build a second one, but am kind of stalled at the point where I have to get decent steppers (My old JGRO has puky little 50Oz steppers and is extremely slow) and a driver.. That point where I don't have the coin to buy the kit I want from HobbyCNC.com

Building one isn't so bad if ya get all the parts cut at a lumberyard.. really straightens the learning curve t'wards how it operates.. I would really suggest building it yourself - save the 200 clams for decent steppers, and you can be zoomin along at 100 ipm.. don't get cheap motors cuz waitin for a 5 ipm machine really really sucks!! (sides - router bits get ruined goin that slow)

I can sell ya my old one for (lessee.. um.. $265 I think) (http://www.hobbycnc.com/products/hobbycnc-ez-driver-board-packages/) plus shipping, of course..

OK, I got them, thanks.
