bounce off home switch.

Could it be the hysteresis of the switch (the difference between the on and the off threshold positions)? Or even backlash on the x axis?

Do not think its backlash as the motor does not try to back it off. I was looking on the mach forum and realised that I have not connected the shielding to earth yet. Naughty me. So I will try that tomorrow and see if it helps.

Sorry, I'm not understanding. I thought you said that the x motor backs off by about 1/2 turn???
