I have been having trouble with my machine and “limit switch” errors … I am new to this machine (recently Borrowed from a friend) … I ran several small projects with no problems but wanted to upgrade the software and so I reflashed the machine. The machine worked well after the upgrade as well!
The only recent change is to the material I am using? I had been making wood projects but recently switched to HDPE … ever since the machine has been acting up!
I can see the machine actually “Arc” as if it has a short before each failure … the arc appears in the lower left of the machine as seen from the front. it is where the spindle chassis frame meets the bed.
Is this repairable? do I need a new switch? I have seen other people having trouble because of grounding issues? Before I start ripping things up I would love the advice of anyone that knows more on the subject?
