Hi there. Only just got back to this after a couple of months.
I thought I was making good progress, but the system is still kaput.
When I disconnect the dir wire from the drive, it moves in the other direction only. It looks like the dir command Is being dragged down?
Swapped x and y signals and the fault remains with the same motor channel.
I can see the dir signal toggle fine on the parallel port from the pc. But it does not toggle at the drive.
There’s 2 PCBs in the chain, and I have replaced 1 with no success, however, I can’t get a replacement for the other as it has been significantly up revisioned.
Does anyone know where I could get candcnc support or parts in the UK?
