Spindle Configuration & Setup Help

dainon

I hooked up a PWM to voltage module following the Workbee CNC w/Duet and Chinese Spindle Control post over on OpenBuilds and a lot of reading over here. I didn't have luck following the Workbee spindle configuration. I'm not certain in that example which specific PWM pins are being used. I chose to use OUT 4 and finally got the configuration not to bark at me for the tool not being defined, etc. I connected a volt meter to the output of the PWM to Voltage Module and sent M3 S4000 or M3 S10000 and nothing happened.

Would someone please take a look at my configuration file and setup? And possibly help me figure out what I'm missing. Everything else works with the CNC and I've been able to play around with it.

Notes for the VFD; however, I'm testing with a volt meter so these are not yet relevant

P0001 = 1 // Source of Operations, 1 = Set by external controls
P0002 = 1 // Source of Operating Frequency, 1 = Set by external terminals
Jumper from DCM to FOR for always on mode
Jumper for VI/VR for pins 1&2 // When using external connection potentiometer

Solved:
I got the spindle working. Switched over from fan to heater, then to the 5V PWM VFD output, which is Out9 (pins: out9->pwm+, GND->pwm-). The spindle works now. Won't stop spinning when I give it an M5, but that's a problem for another day.

Regarding the information out there and trying most of it, this solution is mentioned here:
https://duet3d.dozuki.com/Wiki/Configuring_RepRapFirmware_for_a_CNC_machine
Specifically the section: Connecting a spindle, option 2

Here's the relevant config file section:

M950 R0 C"out9" Q100 L24000
M563 P0 R0 S"Spindle"
G10 P0 X0 Y0 Z0
G10 P0 R0 S0

5V PWM* - Noted at the bottom, connected as Out9, but the 3 pins beside it.
