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 Configuration
" for the calculation!
• After you have calculated the value, open the EEPROM configura
-
tion.
• In the menu bar, choose "
Config
" and the "
Firmware EEPROM
Configuration
".
• 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 firmware) is now adjusted and corrected. To check the
value, select 100 mm again at the filament and have it extrude 50 mm again. If 50 mm filament 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 Configuration" 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 firmware). 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 field "
Extr. 2 steps per mm
".
