I just got a low cost cnc controller/driver in from Ebay.

This had X,Y,Z and C axis.
*Voltage Selection:
12-16V DC power supply for Nema 17 stepper motors
16-24V DC power supply for Nema 23 stepper motors
24-36V DC power supply for Nema 34 stepper motors
(High voltage will burn up the chips or stepper motors!!!)

I set up all setting to Mach3 and before I conected any step motor. I found that one of the 6560 drivers was bad. It was pulling over 3A load.

I ended up removing this bad driver, and order another one.

As for the cnc controller, everything else is working great.

As for the 3A output for each step motor, I would use less then 2A just to be safe.

This controller is very simple in design, it use a full closed-type optical isolation to protect the user's computer and equipment.

This is one great thing about this controller, even if it breaks down.

Parts are cheap to repair, and simple to find.

One way to design a good cnc controller, is reverse engineer one already made!

I admire your enthusiasm, but any TB6560 based stepper board IMHO blows chunks (over considerable distance).

Straight out the blocks you've had one go bad! (there'll be more)

The replacements (TB6560AHQs) aren't easy to find in the Uk, so normally you have to go the Ebay/China or USA route ...so there's a couple of week wait.

Be prepared to to spend a lot of time reading about how to sort all the things the designer should have sorted when he threw together the board....

I'm now boycotting out local chinese takeway on the basis that their compatriots wasted me a few weeks dicking about trying to get the board to perfrom (don't get me started on missed steps!) ...."Oi - Ying ....stick it up your roasted duck" is what I say.

I also started off with the TB6560 driver boards, and I can tell you I had no end of problems.

I had chips doing this:

No end of missed steps, and motor stalling.

The best thing I did was to snap the board in half, and put it in the bin, and ordered my self some 752 drivers.

The motors run so much smoother, run cooler, and much less noise.
