4 Axis TB6560 CNC Driver For NEMA17/23/34 Motor 3A on Ebay update.

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

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.

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.
