Requirements
- Any kind of software you can send GCODE through the terminal like Octoprint
- Piece of paper 90g/cm3
Z-Offset Instructions:
- G28 – Home 3D printer
- M851 Z0 – Reset Z0 Offset
- M500 – Store setting to EEPROM
- M501 – Set active parameters
- M503 – Display Active Parameters
- G28 Z – Home Z-Axis
- G1 F60 Z0 – Move nozzle to true 0 offset
- M211 S0 – Switch off soft endstops
- Move nozzle towards bed slowly until the paper can barely move
- Take note of the Z on the printer display (take that number and add the measurement of the calibration sheet or device used)
- M851 Z X.XX (X.XX being your z offset achieved)
- M211 S1 – Enable Soft Endstops
- M500 – Save settings to Eeprom
- M501 – Set Active Parameters
