Thread: X and Y axis stalling

Dear all,
Long story short I got hold of a great little cnc. However it also came with a problem. It's a 3-axis engraver that sits on top of a box in which all the electronics are.
When I try to calibrate the axis from the machine's controls it makes alot of noise and does nothing. However if I move the axis individually I found that z moves fine, yet X and Y stalls when I press +/-. If want to move them at all I have to hit the +/- repetedly but it doesn't move much anyway.
So the first thing I did was to check the motors and connections and I found that motors work great if I just use the Z controls for X or Y. I also measured the voltage going to the motors and they are all 12v.
It does look like there is a problem with the main circuit board. Anyone out there have any ideas for tests I can do to narrow down the problem? I am starting to think that I will need buy another board.
Cheers,
Dan
