Wheres my PWM signal ?
« on: February 15, 2017, 05:04:26 AM »
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:

Relay control
Use relay output is unchecked.
M3 is set to Output #1
M4 is set to output #1

Motor conrtol
Use spindle motor output is checked
Use PWM control is checked
Use step/dir is unchecked.
PWM Base freq =5
Minimum PWM 0%

Good news is the Spindle is now turning and responding well to the M command, voltage output rises from 0 - 5Vdc according to the speed selected, I.e 0rpm = 0Vdc and 25000 rpm = 5Vdc
A and Z axis are Jogging under manual jog mode ( just got to set up my motor tuning)
So we are on our way, not to set up the limit switches.
