Machine Calibration

Heating PID Calibration Instructions

  • PID calibration can optimize the stability and response speed of heater temperature control. The table below lists the calibration commands for different heaters. The TARGET parameter can be adjusted according to the actual printing temperature requirements.
Heater TypeCalibration CommandDescription
Extruder
Loading...
Calibrate the main extruder; change TARGET to your commonly used printing temperature (e.g., PLA typically 190–220°C)
Extruder 1
Loading...
If the device has a second extruder, use this command for calibration and adjust the TARGET temperature
Heated Bed
Loading...
Calibrate the heated bed; it is recommended to set TARGET to the actual bed temperature used during printing (e.g., ABS about 90–110°C)
PTC Heater
Loading...
Calibrate PTC-type heater; set an appropriate TARGET temperature according to the material used

Tip: After calibration, be sure to run the command below to save the parameters, or the calibration data will be lost after a reboot.

Extruder Calibration

Tool Preparation

To ensure the accuracy of extrusion calibration, prepare the following tools in advance:

ToolDescriptionRequirements
Vernier caliper or rulerFor measuring actual extrusion lengthAccuracy no less than 0.01mm, range ≥150mm
Marker pen or transparent tapeFor marking on filamentClear and recognizable mark
Test filamentFor performing extrusion testsIt is recommended to use PLA or PETG with decent quality

📌 Tip: Using stable quality filament and precise measuring tools will yield more reliable calibration results.

Equipment Readiness

  • Ensure filament is loaded into the extruder
  • Heat the hot end to the recommended printing temperature for the filament
  • Confirm the printer is in an operable state

2. Mark Initial Position

  1. Use the prepared marker pen to make a mark on the filament
  2. Mark position: approximately 70mm from the extruder inlet
  3. Use a digital caliper to accurately measure the distance from the mark to the extruder inlet
  4. Record this value as the Initial Mark Distance

3. Perform Extrusion Operation

  • Enter the following commands sequentially in the printer console:
G91
G1 E50 F60

Important Notes:

  • The extrusion process takes about 50 seconds; please wait for it to complete
  • Low-speed extrusion must be used, as high speed will increase pressure and affect result accuracy
  • Do not use the "Extrude Button" on the graphical interface, as it uses fast extrusion mode

4. Measure and Calculate

  1. After extrusion, use the digital caliper to measure the new distance from the mark to the extruder inlet
  2. Record this value as the Final Mark Distance
  3. Calculate the actual extrusion length:
Actual extrusion length = Initial mark distance - Final mark distance

5. Calculate New Rotation Distance

  • Use the official formula for calculation:
New rotation_distance = Old rotation_distance * Actual extrusion length / Requested extrusion length
  • Requested extrusion length: 50mm
  • Round the result to three decimal places

Calculation Example:

  • Old rotation_distance = 24.000
  • Actual extrusion length = 48.5mm
  • New rotation_distance = 24.000 * 48.5 / 50 = 23.280

6. Update Configuration File

  1. Open the printer configuration file
  2. Find the [extruder] section
  3. Modify the rotation_distance parameter to the newly calculated value
  4. Save the configuration file and restart the firmware

7. Verify Calibration

  • If the actual extruded length differs from the requested extrusion distance by more than 2mm, it is recommended to re-perform the full calibration process
  • Repeat calibration until the error is less than 1mm
  • It is recommended to perform at least two calibrations to ensure stable results

Notes

  • Avoid touching hot components during operation
  • Keep the caliper perpendicular to the filament when measuring to ensure measurement accuracy
  • Save and restart the firmware after each configuration change
  • Do not move the printer or interfere with filament flow during calibration

After completing the calibration through this guide, your extruder will be able to extrude the required filament length more precisely, thereby improving print quality.
