mach3 false limit switch triggers

[johnrobholmes]

Ive got a little taig mill thats for small jobs and it just started throwing out "limit switch" errors that are screwing up my positioning and pausing programs at the worst time. But I have no limit switches! There is no plugin for the motion controller, there are no switches. Im very confused at this new problem.

any suggestions?

When I hit home on the software it goes to my home location as set in software. g28 is going to a random point in space and hitting limits. Weird, I dont know what happened but things are funky now.

figured it out while viewing program coords instead of machine. I hit set home and the Y value didn't set zero, but offset a few inches. moved it again, hit home, closer to zero. repeat 4 times and home was now at zero where I set it. maybe something to do with being in incremental mode? I had to reset the machine power to get back into absolute. it wouldn't take g90 or g91 commands.

0/10, dont recommend mach3 controlled machines

Grounding issues. Find your ground pin on you IO board and make sure everything is grounded together. There may also be a shielded cable which should have been grounded properly
