The document provides instructions for calibrating 3D printer extruders and flow rates. It discusses measuring filament extrusion to calculate new steps per mm for the extruder. It then provides steps for slicing a test print with specific settings to measure wall width and calculate a new extrusion multiplier to achieve the desired extrusion width. The overall document focuses on calibration processes to ensure accurate extrusion and prints.

- 36. Makerbot Replicator Easy to use and beginner friendly Great for rapid prototyping and dust collectors Great features like quick swap 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.
