E Steps Calibration

Calibrating with direct drive and hotend attached

To calibrate E steps with the hotend attached you should extrude as slowly as possible to compensate for the resistance of the nozzle. The following commands at the OctoPrint terminal will achieve this:
G21          ; set to millimeters
G90          ; use absolute positioning
T0           ; select extruder 0
G92 E0       ; zero the extrusion distance
G1 E100 F50  ; extrude 100mm very slowly
G92 E0       ; zero the extrusion distance
