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). :proj: 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. |

Another rethink about the base design. Instead of having to cut a 10" wide slab on aluminum down to 5" . I think I'll keep it 10" deep and fill in the the front and side with thinner plates and use another 1" thick piece at the back If I cover the front left side with the extruded T-slot I have, it might be useful for mounting a rotary table for cylindrical grinding |
