I recently bought the seemecnc extruder upgrade and I stalled them on my A10m from geeetech but I need to do the e steps to calibrate them.The problem I'm having is when I connect to pronterface and enter M501 it doesn't show the current e step numbers.I know it's over extruding because I marked it at 100mm and it went past the mark and the extruder is skipping on the filament I guess because it is goi g to fast,is there another way to do it I'm not really sure how to get into the marlin firmware the firmware I use was setup so that I could just flash to the printer and be done so I didn't set it up.
