Hi everybody , what is the best procedure to do when  I during work (cuting) on my cnc router recieve message on my MACH scren that "the limit switch is trigerred"  , normaly the machine stops . But the machine not realy triggered limit switch , I think that is because some electric noise occur from time to time . Now my question is how to continues with work . I try simply to resset the warning on the screen and pusch the start button again . But that do not work very god . It is look like a some stepps missing between last stop position and new start ? What I can do ?
Thank for your help .    

You  would need to rehome, scroll to the line you want to start from then use the Run From Here feature.

To prevent future problems it may be a good idea to fit a 0.1uF capacitor between each switch input and GND on your Breakout Board. This trick seems to have cured the electrical noise problems of quite a few in the past.
