Hi there - firstly thanks for reading this!
I'm making a DIY cnc router using some Nema23's and a TB6560 board off ebay. Z and X axis work fine, but Y-axis will only travel in one direction. I've tested the y motor on the x output and it works fine so it's not the motor wiring. I've used the multimeter to confirm I get an output from the parellel port and cable on pin 3, which according to the rubbish manual I got with the board is the Y Dir output...

I can see only two options:

1. The manual is wrong and Pin 3 is not the Y-dir input to the board - can anyone confirm this or suggest a different pin?
2. My board doesn't work!

Regards,
Martin
