I'm writing to see if anyone has come across or edited the Sprinter firmware to utilize the 5 axis controller (RAMPS 1.4). I'm not using it for a 3D printer but am using 5 stepper motors that I want to control independently and possibly simultanously. I've seen some that allow a tool change between the two extruder channels but I need to be able to operate through both E channels at the same time. Is there any reason this won't work from the hardware side? If anyone has come across firmware that is already set up for this would be awesome. Any help is greatly appreciated.
