I don't suppose anyone has (successfully) built a cnc router from a kit have they? I have just returned to mine (started building it some years ago then dismantled it to move) and still can't get the x-axis drive to work.
It was one of the drivers, Trevor. Fortunately there are 4 identical chips that plug in so it's easy to swap them to establish whether the fault is in the chip or the pcb - I was unlucky enough to have faults in both, though I suspect the pcb fault caused the chip fault. I now have a spare chip with heat sink fixed in place ready for the next failure.
Well done Brian! What was the issue?
