I'm using and ESS Smooth Stepper with a CM106 break out board.
I'm running Mach3 Turn for Lathe.
Start spindle with S6000, I have no output on pins P2.1 Vdc and ground which are connected to my inverter drive on pins 2 & 5
I have pi 1:14 to turn on the spindle relay and this works fine but I have no spindle movement.
The ESS plugin is set to:
Use relay output is unchecked.
M3 is set to Output #1
M4 is set to output #1
Use spindle motor output is checked
Use PWM control is checked
Use step/dir is unchecked.
PWM Base freq =5
Minimum PWM 0%
