Extruder configuration problem


New member
Hi all,

I have just finished building one Voron 2.4 350 rev C LDO kit,
I have a small extruder configuration problem.
the extruder motor supplied in the kit is a 36STH20-1004AHG(VRN) if I'm not mistaken the gear of this motorIt has 10 teeth, the white bontech gear has 50 teeth,therefore in the EXTRUDER section of the printer config under GEAR _RATIO I indicated 50:10 and under full_steps_per_rotation I enter 200 because the motor is 1.8 degree.
With this config when I try to extrude 100 mm of filament the extrusion result is about the double 200mmor more ,so I try to adjust the GEAR_RATIO to 50:17 and the extrusion is almost 110mm …what am I doing wrong ?
I’m not at home and I can’t copy and past my config parts but is :
gear_ratio 50:10
full_steps_per_rotation 200
rotation _distance 26.2436543
with this config the extrusion is good
