extruder assembly
37. Extruder Calibration
1. Measure 100 mm of filament and
mark both ends of the
measurement
2. Extrude the filament until the first
mark sits at the top of the
extruder assembly
3. Set your printer to manually
extrude 100mm of filament
38. Extruder Calibration
4. Measure the distance between
the top mark of your 100mm and
the top of the extruder assembly.
Your mark may have gone into the
extruder. If this has happened,
mark at the top of the extruder
and retract the filament until your
original mark clears the top of the
extruder. Measure the distance
between those two marks.
39. Extruder Calibration
5. Add or subtract that
measurement from 100. If your
original mark was above the top of
the extruder, subtract. If the mark
went into the extruder assembly,
add. This number is the actual
mm extruded instead of the 100
you set it to extrude.
6. Make note of that number. In this
example - 105.03
40. Extruder Calibration
7. Open your Firmware EEPROM
Settings.
8. At the far right of the steps per
mm line, make note of the
number in the E field. 113.68 in
this example.
41. Extruder Calibration
9. Multiply this number by 100 and
then divide by the actual
measurement. This will give you
the new steps required to extrude
100mm of filament
10. NS = (100*OSteps) / Actual Length
In this example:
11. 107.958=(100*113.68) /
105.03
42. Extruder Calibration
12. Input this new number into the E
field in your Steps Per MM line of
your firmware EEPROM settings.
13. Save and move on to Flow Rate
calibration.
43. Flow Rate Calibration
1. Make a new slicing profile with
the following settings:
Print Settings
• Your standard layer height (.3)
• Perimeter of 1
• Solid layers of 3
• 0% infill
• Default extrusion width (.42)
44. Flow Rate Calibration
2. Filament Settings
• Extrusion multiplier of 1
• Measure the diameter of your
filament with a set of calipers
and put that number into the
diameter field.
45. Flow Rate Calibration
3. Slice a basic cube using this new
slicing profile.
4. Start that print and stop the print
after a few layers after the base
layers. 5-10 is a good number.
5. Measure the wall width with a set
of calipers and make note of that
number
6. We hope this number will be the
same as the default extrusion
width. It probably won’t be.
46. Flow Rate Calibration
7. Divide your target number (.42) by
the width of the wall you
measured. For example .42/.49
8. This number will be your new
extrusion multiplier. In this
example .85
9. Place this number into the
extrusion multiplier field.
10. Repeat the last 6 steps to verify
your new extrusion multiplier
results in your desired extrusion
width.
