Hi. Hope I'm posting in the correct place and apologies if I don't explain problem as I should.
I have a Sherline mill with Routout boards running Mach 3. There are 2 limit switches on each axis. Everything works fine except top (home switch) on z-axis. Switches are NC (normally closed).
It isn't a faulty switch and seems to be connected properly to the board however nothing seems to detect it. The bottom z axis switch works fine. I can upload any pics, config files etc that may help.
Would love fault finding suggestions. David
