This is truly awesome, Bart. I’ve been looking at your ‘Grbl_ESP32 CNC Development Board V3.1’ and wishing it had more features… Then you post this! My MPCNC hasn’t been running that long, but I can’t think of anything else I’d add.
When the boards are available, I’d love to try it out as an alternative to my RAMBo. I already have a small cache of ESP32 boards and stepper drivers that would love to be put to good use.
