I am using a cheap NO switch to create a digitizing probe. The switch itself is a simple switch with a roller point often used as a limit switch. It is connected to pin #11 and 5v. The switch works perfectly. G31 probes down, the switch trips and a line is written to the M40 file. The problem is the Z height recorded is wrong! X & Y locations are correct but the Z height is off by about 0.25 or so. It shows correctly on the Mach3 screen. Anyone have any idea why the Z height would be recorded wrong?
Thanks Dave
