dual extruder problem
June 14, 2015 02:17PM
I have recently installed dual extruders. have MKS Base v1.1 board and using Marlin Firmware.
have everything working except E1 extrudes about 10mm instead of 1mm . E0 works fine. I can't seem to get any help on how to fix the firmware so I can calibrate the extruders independantly, so was hoping someone had another suggestion to fix this problem. I can swap extruder positions and the problem stays with whichever one is connected as E1.

This might seem like a dumb question, but did you set the initial values for E-steps per mm for each extruder? You need to select each one independently before setting the value:

T0; Select first extruder.
M92 E443
T1; Select second extruder.
M92 E443
