You may receive the following in your output if you've failed to set your locale properly:

- Heat up the nozzle to desired printing temperature.
- Home all axis.
- Lift nozzle by 50mm (to make room for the filament!)
- Execute the following commands (one by one)
G92 E0This resets the "extruded material" value to 0.G1 E100 F100This extrudes 100mm filament with 100mm/min.
- Now measure the distance between extruder entry and the mark on the filament. For example, if it is 28mm instead of 20mm (120mm - 100mm) then the extruder is underextruding by 8mm ==> 92mm instead of 100mm. If it shows 15mm then the extruder is OVERextruding by 5mm ==> 105mm.
-
c:= current value inprinter.cfg -
m:= measured left over filament -
d:= desired mm -
n:= new value forprinter.cfg -
((120 - m) / d) * c = n -
((120 - 28) / 100) * 0.010500 = 0,009660 -
(92 / 100) * 0.010500 = 0,009660
For underextrusion, the new value is lower than the old one. Play around with the last two numbers to fine tune.
