Does anyone know of a GRBL precompiled for the RUMBA board? Trying to understand the differences in pin mapping for cpu_map_atmega2560.h & pins.h on repetier/marlin is super frustrating for lack of commenting on the repetier side.
+Peter van der Walt Wow… that makes me a sad panda. From what I can see, it would be possible on the RUMBA except for X is on pin 17 for some inexplicable reason. The 3 extruder step pins share a port, and Y and Z share a port. Do you think there is any way I could ‘repurpose’ the drivers wired as Y and Z to X and Y? Or is the shared port with all step pins?
