problem: y-axis only moves in one direction using TB6560 board off ebay
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

Do you have the 3 or 4 axis board?
Also try swaping or reseating the optocouplers for that axis.

did you get it from savebase?

Thanks for the replys - it's a 3 axis board I got off ebay. I'll try swapping the opto couplers as suggested.

Just for an update. I tried swapping my opto couplers around and the Y-axis TB6560 chucked its dummy out and popped! It now has a big crack in it. I've been corresponding with the supply who seem very helpful and have agreed to have it back and replace it with a new one. Fingers crossed the new one will work perfectly and I'm be able to continue :)

I HAD THIS PROBLEM oops (caps lock) and found I had loaded the wrong motor direction output port. My Z axis was trying to dig a hole in the table as it would only go down. Stopped being excited about getting movement and reset to the correct port. As there are not many outputs and you will have used most of them it should not take too long
cheers
