If you are controlling the speed of your spindle with LinuxCNC instead of just
ON/OFF/DIR, how are you doing this?
Well, on my Bridgeport mill, I use a spare channel of my
analog DAC to deliver 0-10 V.
On my minimill, I have the DC motor run off one of my PWM
servo amps.
Others using my PWM controller or stepper controller use my
Spindle DAC, an 8-bit D to A converter with an amp and
polarity switching circuit to get either 0-10 V or +/- 10 V.
