I'm no expert on these so I thought I'd come here and ask.
I have a HobbyCNC Foam Cutter board Rev 1.
One stepper motor on my foam cutter, has failed and another works
intermittently. Something on the board has gone as I can swap the steppers to a different output and they work fine.
What would my next steps be to Investigate or repair?
It's not the computer, stepper motors or parallel cable as they all work fine.
Thanks
Matt
