Suggested PWM frequency for a minimal Novamill conversion

[Clive S]

I have done a conversion on a Novamill using a Mesa 7i92. I also changed the feed and speed pots to alps encoders.

Here is a link for some pics including the ATC https://photos.app.goo.gl/qUwAmX5nGVTGMZyi6

I don't remember now but I think this might be the bit you want.

# ---Setup spindle at speed signals--- on bob relay pin DB 17

setp hm2_7i92.0.gpio.024.is_output 1

net spindle-enable hm2_7i92.0.gpio.024.out
sets spindle-at-speed true

#Below sets position of relay contacts on power up
setp hm2_7i92.0.gpio.024.invert_output true

#PWM Generator signal/setup

setp hm2_7i92.0.pwmgen.pwm_frequency 1500

setp hm2_7i92.0.pwmgen.00.output-type 1
setp hm2_7i92.0.pwmgen.00.scale 5000
setp hm2_7i92.0.pwmgen.00.enable true
