Spindle RPM is set by Mach, using PWM to analog converter to operate a VFD. According to Mach SActual, spindle rpm stays steady within 2 or 3 RPM. I am using V. R3.043.060
Offending code is as follows:
M6T0303
M3S400
G4P1
G0Z.4X0
G95
G76X-.02Z-.5Q1P.07692H.005I29.5C.05
G94
G0X.1z.5
M30
END
And:
G94
M3S200
M6T0303
G0Z.3X-.01
G95
G32Z-.5F.07692
G94
G0X.05
Z.4
M30
END
Running the G32 cycle multiple times produces the same results as the G76, the thread does not start at the same place everytime. Also, disabling thread diagnostics had no effect.
Thanks,
