Mach 3 starts on its own
« on: June 29, 2015, 01:42:30 PM »
I turned on my flame table today, powered everything up, and pressed the red RESET button and the Y axis started to move on its own.   I have not made any changes, or added any updates.

I am using Toms CandCNC BOB, and it has a LED for each axis and it flashes when Mach3 tells the axis to move.   This LED for the Y axis is flashing, so Mach is telling the axis to move.

any idea where to start?

Good guess!  I unplugged the pendant and the movement stopped.

When I plugged the pendant back in, it started to move again.

I use the probing routine to find the top of the plate.   This is not working now either.

When the program runs, it goes to the first top of the plate z move, then scrolls to the end of the program fast.

the x and y axis move on their own very slowly.

could the plug in be corrupted ?
