Hi all,

The supplier thread above seems to be locked, and the thread it links to doesn't exist, so.... Here's an attempt to create a new supplier thread.

I have found and plan to use the following suppliers to build a JGRO...

Suppliers
======

Small Parts and Bearings (http://www.smallparts.com.au/cgi-bin/store/product.pl) Most of the hard to find bits including but not limited to couplers, bearings, Delprin etc. Big catalogue although I haven't ordered from them (yet).

Jaycar (http://www.jaycar.com.au) Electronic components. Most of what you will need if you want to build your own breakout board and driver boards.

RS Components (http://www.rsaustralia.com/) Electronic components and engineering supplies. If nowhere else these guys will probably have it, I will be sourcing the toroid for my power supply from here.

Oatley Electronics (http://www.oatleyelectronics.com/) Surplus and electronic bits supplier. In particular they have the IRFZ44 FET required for the driver boards, get em while you can... Always worth a look at what these guys have. Their CNC drivers and constant current drives look the goods for a CNC.

Futurlec (http://www.futurlec.com.au/) Some of the harder to find components, namely the motor controllers needed for the PICSteps and other bits and pieces. These guys also have a PCB fabrication service which doesn't seem all that pricey.

Ocean Controls (http://www.oceancontrols.com.au/) Industrial and commercial electronics supplier. These guys have steppers at the best prices I have seen in Australia for new steppers, still very expensive compared to the US though.

Southern Steel Cash and Carry (http://www.southernsteel.com.au/sscc.htm) Steel supplies, in particular the black pipe required for the bearings.

Bunnings - MDF, Bolts, Screws etc.

I bought my steppers from an E-Bay supplier in penrith (it_equip_on) who repairs printers for a living. It may be worth mailing him directly or watching for his auctions.


Suppliers Wanted
===========

* Aluminium Plate - 12-20mm... Perhaps a scrap merchant.
* ACME Thread - 10TPI (I can find 6 TPI).

I am looking for an ACME Thread with 10TPI as well. So I am going to ask where did u get yours from? (I dont mean Agro)

Try RS components for couplers, prices look good, not the US but still better than most. Ocean Controls for steppers?

Power supply components?

Andy

(edit: whoops in original entry, but what source is the cheapest?)

Added to the list. Cheers ;)

Andy,

Try RS. I will be buying the toroid, bridge rectifier and large cap from them. I'm a little surprised how hard it is to buy large transformers these days, a few years ago
you could buy them from dick smith.

Agro.

Jaycar have toroids, Altronics have a wider range including some with low voltage tap for the logic etc. Been using a 160VA on the micromill hardly gets warm, Got a 300VA for next project.

I missed the toroids at Jaycar... I will drop in to their warehouse today :)

The 18v 300VA looks the goods. This should rectify out to 23v and supply a healthy 16 amps which I will be happy with.

Cheers

Agro.

We use those toroidals all the time. We have not had one fail to date.

I have found that a good place to go for Aluminium Plate is to find a local trailer body builder or bullbar manufacturer. They generally have good size offcuts up to 16mm thick. I used to use Heard Bullbars here in Wollongong but they went belly up a few weeks ago.

See below

Anyone got a source for V bearings? I need 6 at max.

Andy

Alltronics have 300va toroidals on sale for $40.00 usualy $80

Just got myself on with 30v 5a - 30v 5a - 15v .5a - 15v .5a

Should suit my need just right. About 42v rectified at 10amps.

Can run some regulators for 5v control and 12v fans on the minor windings.

And I ordered yetserday arvo and it arrived at 8:30 this morning.

Can't complain at that :)

Small Parts and Bearings have them listed but don't carry stock according to their site.

Exy :rolleyes: About $40 and about $60 with stud.

Greolt

Thanks for that Greolt

I'm very interested in the toroid at that price.

Could you give me a web link or phone number?

(NB I was also at Nigel's bbq last week.)

Thanks Greolt

Excellent tip off. Have bought a 35V + 35V + 15V + 15V 300mVA toroid for $40. Picked it up from the store an hour ago.

For any other Aussies going down the Gecko path, consider this opportunity now.

These guys have a website... www.tea.net.au... TR20x4x2000 $154.65 but they will cut in increments... Finest pitch in rod above 10mm is 4mm which will give you roughly 6 tpi They do rods at 2 and 3 mm pitch but only in 10mm major.

You can also try the following site www.motiontech.com.au
the guy to speak to is Kevin

TR20x4x100 is approximatly $5.00..any length up to 9 meters ...

Cheers Mark

There is a small engineer shop in Northern Suburbs Melbourne who cut their own acme.

Prices are $14.87 + GST / foot (1/2 * 8) and (5/8 * 8) with nuts at $13.96 and $13.30
or $16.00 + GST / foot for (1/2 * 6) or (5/8 * 6) with nuts at $14.70 for either.

Contact point is Matt - 03 9354 2588.

Greetings fellow Aussies.
Jon from Townsville here, wondering where you guys source your stepper motors from. It seems like all the reliable sources with half decent motors are from USA, and the freight costs seem over the top.
I was all set to make a purchase from oceancontrols, but then I read a post that states that they arent very strong motors while spinning.
If I have to pay $80 in freight to get them from US, then I suppose I will, just like to purchase a bit closer to home. Recently had a bad experiece with missing freight from EU so am a bit more cautious now.

Jon

Hi Jon

Sourcing from Aus is not good and US shipping costs are too high.

I bought from UK (www.motioncontrolproducts.co.uk) and as my wife was in UK, she bought them back in her luggage (she was not impressed!!)

They are a good supplier. Well worth checking out. They advertise on Ebay. Don't know their o/s postage costs but were very efficient and reasonably priced to my sister-in-law's address in UK.

Hi Jon,

Check with Roger Cagill from Taig Machinery in the ACT. He has stepper motors for sale. single, double and tripple stack 23 steppers. And his prices are very reasonable.

Hi Greg,

Just starting to think about the electronics for my slow Joes build and have been looking at a kit from HobbyCNC with 305oz steppers but just need to source the power supply locally.

It appears the HCNCPRO can only be powered up to 42VDC max (http://www.hobbycnc.com/hcncpropkg.php) or am I reading it wrong. If so, I guess that means that the 30V transformer you got (part # MC5530?) would rectify slightly higher at 42.43VDC (30 x square root of 2) so would I need to go for the 25V version (part # M5525) which should provide 25VAC @ 12A or 35.36VDC once rectified if I'm calculating it correctly?

Unfortunately I'm way too late for the special, but I'm signing up as an Altronics Wholesaler for my A/V business so pricing should be good.

Are there any other transformers I should look at instead?

I've also noticed they now have an emergency stop button in their new catalogue (http://www.altronics.com.au/index.asp?area=item&id=S0820) which might be of interest.

Cheers

Claudio

There are many more electricly savvy people to ask but here is my take.

You will actually lose a small amount with the rectifier but it is probably not leaving much margin with the 30v one. I would go with the 25v one.

My idea of using the secondary 15v winding to run through a regulator for 5v control did not turn out to be practical.

The regulator chip had to disipate too much heat.

Tried to unwind a few turns on the secondary but it was wound on before the primary and I wasn't going to unwind the whole lot. :eek:

So I ended up putting another small 9v toroid in for that 5v regulator and to run 12v fans unregulated.

If you need a capacitor I have a box of 33,000uf ones I got cheap somewhere. They're about the size of a soup can. :)

Hi Stuart, do you know of anyone that has used any of this mobs products?
they seem to be priced quite well with there stepper motor drives compared
to a lot of the yank stuff.
I need to speak to them regarding 4 bipolar drive and a breakout board but it would be good if someone could give a bit of feedback on there products.


Cheers Pump.
