Extruder calibration

Checking if we have 100mm length

G91 - For reverse in my case
G1 E100 F100 - move 100mm

Formula

E(res) = (E(res0) * L0) / L

In my case

96.875 = (100(desired length) * 93(default firmware value can be checked with M503 command)) / 96(extruded length)

Set new value

M92 E96.87
M500
