I started out with the Chinese version from ebay that came with the power supply and steppers, yet all I could ever get to work was the Z axis, and one of the other axis' would lock up from the enable. I was able to switch around the motors and all the motors worked when hooked to the Z axis.
Wrote it off as a bad driver board and sent back to China in for repair, and then bought the TB6560 from cncgeeker.com to replace it for a while. I just got it wired up tonight and am having the exact same problem, but this time only the Y axis is working, and still only one other axis is locking up from enable. Curious, I checked the pinouts and on my first board Z axis used pins 4/5 for Z step/direction, and on my current board it uses pins 4/5 for Y step/direction. So basically the only inputs going across are 4/5 and two of the enables.
The parallel cable has also been tested and all pins are good.
I would be dead set as it being a computer problem, but I tried shorting the manual pins out, but again only Y will move. I have tried two separate computers, one a Dell 3300 and one a Dell 8300, both on EMC2. Is there possibly a setting in the computers parallel port that needs to be adjusted?
Thanks in advance!
