Extruder steps/mm calibration
I try to calibrate my Extruder settings for a new printer. To get to the steps/mm, I extrude 50 mm, measure actual extrusion length on filament and change the Extr1 steps per mm in Firmware EEprom settings accordingly. That's the theory.
Actually I get different values for extrusion length, when I use the Repetier manual control for 50 mm or when I use direct Gcode sending (G1 E50). It also differs when I send G1 E50 and after that G1 E-50.
Problem is that the operations are not completely repeatable. So I can't say, e.g., manual control gives always 50% of the Gcode values.
Best regards Ludwig
