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,

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.

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.

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.as...=item&id=S0820) which might be of interest.

Cheers

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.

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.
