Surface grinder concept/project
BillTodd:
Experimenting with a Raspberry pi pico servo.
This sort of thing used to be difficult. Now all you need is a £5 microcontroller and a few lines of python and you have a servo controller.
Here , the pico's PIO (programmable input/output) is configured to be two quadrature counters (it can easily have 8) , one handling the motor position, and one counting the handwheel input. One of the pico's PWM outputs is amplified, filtered and sent to the servo amps (on the right).

I feel the need to make a pico DRO ....

Small update:
I've acquired a nice Eclipse 14 x 6 magnetic chuck and updated the design slightly to incorporate some 40x40 and 80x40 extrusion for T slots and slide support.
