Homing problem with corexy
@Andypos you said that you have corexy machine, controlled with Nucleo board. Do you have problem with homing ($H)?
Mine just goes to +x limit switch, then goes back, and goes to +y but never touch switch. I saw that GRBL head problem with homing of corexy, but I think they fix it.
Also, when it is "done" with homing it restarts, prints on terminal: Grbl 1.0c-STM32 ['$' for help] ['$H'|'$X' to unlock]
Now it works, I have changed some things in src/grbl/limits.c You can see the changes in this commit: commit :smile:
@VojislavM Good job :). I do mechanical part ,now. I bulding H-bot ( work like corexy) version. If You change in Arduino CNC sheffild logic for 3.3 V?
@Andypos I am not sure what is your question, but I have no problem with Arduino shield and Nucleo 3.3 V logic.
It is ok ,if do not use analog input. See https://developer.mbed.org/questions/4738/5V-tolerant-pins-on-Nucleo-boards/
