Lost PWM after upgrade to newest version of Carbide Motion

Since the upgrade, anything above 499 rpm instantly sends the spindle to 24000 rpm. From what I remember, sending the $30=24000 command should calibrate the pwm signal. What am I doing wrong? Thanks!

Make sure the bit runner option is not turned on in your configuration.

It worked! Unfortunately I use the Bitrunner to turn on and off my spindle coolant plump. I might just have to go back to the older version of the software.

It’s better to use a current sensor to manage the vacuum on/off.
