motor driver, then let LinuxCNC do the rest
(encoder feedback, PID, command output). I use Pico's PWM input motor
amplifiers to run brushed servos. I believe there are equivalent setups
for brushless motors. This way LinuxCNC and therefore _you_ get full
oversight and control of the system.

changers have the new tool ready before making a change. With LinuxCNC
on-board there is plenty of control resource available.

the current up and repeat until
the motor runs at the desired temperature (usually barely touchable). I
believe that the motor sitting at idle will produce the highest temp.
