Re: Syil X5 Speedmaster Z axis limit switch
I believe you are getting a spurious spike on z axis making mach3 say it is homed.
Symptom is that z axis ends up green.
My SX3 gets spikes on z sometimes due to dust on z slide causing exactly the same problem.
For me, if the home position is important, a blast with compressed air fixes it.
I ALWAYS home machine at turn on to ensure soft limits always work,
but doing mostly manual work it only means I can't get z axis high enough.
The cutter stops it in -z direction.
So I then just re-home z from the diagnostics page.
When homing, my mach3 ALWAYS turns on soft limits.
I achieved this using screen.exe (mach3 screen designer) by adding 'turn on soft limits' to the end of each screen button that does homing.
Super X3. 3600rpm. Sheridan 6"x24" Lathe + more. Three ways to fix things: The right way, the other way, and maybe your way, which is possibly a faster wrong way.
