Stepper Module GRBL doc ?

  • Hi,
    I just bought the stepper module but can't find anything about limits ?
    I had to dig into the module's code to discover that it is using arduino pins 9, 10 and 11.
    Anything official about that ?
    How am I supposed to wire it ?


  • Hi,
    I'm looking for this informations too.
    It seems on the ATMEGA328 it's "DX 9 PD5/PCINT21/OC0B/T1"...
    but I have no idea if it is possible to connect a switch there.

  • Hi! Did you find any information about the M012 stepper module? I just bought one as well and am having a lot of difficulty finding information about commands, and basically how to run it from a Raspberry Pi 4. Any info you have found would be useful! I cant find any Python code anyone may have written for it.
