Recently I started having issues where it appears my zero is being reset mid-way thru the project. I'll start, everything runs good for awhile and then bam, it starts overlapping or running off the material. No sounds or warning, you'll just see it move to an already carved location, and carve a different part of the design. When I emergency stop it returns to a 0,0,0 point about 4 inches right of the actual starting point (Y & Z seem fine). Any suggestions? I'm at a loss here and of course the busiest time of the year.
I've had my Shark 2 years. During which :
I've replaced SD card 4 times,
I grounded the controller and have it on a rubber mat now,
Had to stop using virtual zero since my machine would take off,
Several issues with my computer not finding the controller,
My machine sometimes re-carves the last design even with the new design showing on the screen as loaded,
Disabled emergency stop on the controller since my machine wouldn't turn on at one point.
