Hello,
at first I would like to thank you for your hard work on GRBL for ESP32. I had similar idea, but my knowledge of programming for this was to low to even start so I was hoping someone very clever will do it and that happened so I´m glad for that.
I saw your video about implementation of axis A, B and C to your FW, but I´m bit confused if these can be used to control stepper motors and if yes, could you help me with pin definitions please? #1 – bdring 于 2019-12-30 You can use the 6 axes for any combination of steppers, servos, etc. If you use the RMT periferal to generate steps (recomended) you need to assign one of the 8 RMT channels to each stepper motor you define.
