Calculation and correction of the feed
The formula for calculation of the actually conveyed volume is as follows:
Total length in mm - residual amount in mm = actually conveyed volume in mm
100 mm - 46 mm = 54 mm
The formula for calculating the new value "Steps per mm" is as follows:
Conveyed volume in mm: Actually conveyed volume in mm * Current value Steps per mm = New value Steps per mm
50 mm : 54 mm * 280.000 = 259.259
The value "Current value steps per mm" "280,000" is only an example value here. Always use the current value entered in "Firm-
wareEEPROMConguration" for the calculation!
• Afteryouhavecalculatedthevalue,opentheEEPROMcongura-
tion.
• Inthemenubar,choose"Cong" and the "Firmware EEPROM
Conguration".
• Inthenewwindow,scrolluntilyousee"Extr. 1 steps per mm".
• Changethecurrentvaluetothevaluecalculatedanewbefore.In
our example, change 280,000 to 259,259.
Observe that you also must write the new value with a dot instead
of a comma.
• Toacceptthechange,click"OK".
Thevaluefortheleftextruder(extruder1inthesoftware/extruder0inthermware)isnowadjustedandcorrected.Tocheckthe
value,select100mmagainatthelamentandhaveitextrude50mmagain.If50mmlamentareleftover,thevalueisright.Oth-
erwise, correct it again.
Important! You always need to use the current value "Steps per mm" for calculation. Read the current under "Firmware
EEPROMConguration"beforecalculation.
If you have acquired the printer with dual extruder, repeat the same procedure with the right extruder (extruder 2 in the software /
extruder1inthermware).Theprocedureisnearlyidentical.Switchofftheheateroftheleftextruderagainandheatuptheright
extruder. Switch to extruder 2 (drop down menu in extruder 1).
 Enterthecorrectedvalueineld"Extr. 2 steps per mm".
