As the title says I am trying to calibrate my extruder (Folger Tech Prusa i3, RAMPS board, Marlin firmware). I am using Repetier Host and trying to access the EEPROM settings, but there are no values showing up. Just 0’s across the board. Why would none of this info be showing up for me?Also figured I could change the steps/mm for the extruder in the configuration.h file and reload the Marlin firmware. However, it has been a while since I’ve messed with any settings and I no longer have the copy of the firmware file that is currently loaded on my RAMPS board, so I’m guessing I’d basically have to start over from scratch going that route. http://ift.tt/2fpbQ3h
