So I have a Winbo SH155L printer that seems to be running marlin firmware (not sure how to check this).
I tried calibrating my extruder with the help of youtube tutorials, but I am unable to get the extruder to extrude 100 mm of filament.
I tried adjusting the E steps/mm (I did all the math) many times and the amount extruded seems to be random and cannot be calibrated.
The command was given on the LCD controller ( moveaxis by 1 mm), Extruder and then i selected a value of +100 with a temp of 210C.
I kept saving the new E steps/mm value and doing the test again but the results seem to be random and I am unable to get it right.
What am I doing wrong? Should I print a Gcode file for this test? Should the commands be given though the USB cable from my PC (if so can this be done with S3D?
