Be sure to follow calibrating-rotation_distance-on-extruders
My personal procedure:
- Remove the nozzle
- Extrude 50mm of filament
- Cut the filament at the heat block with an accurate side cutter
- Measure the cut off filament
- Calculate new rotation as per above link
- Repeat from No. 2 to verify
Edit: Make sure to disable all additional extrusion modifiers (like in Octoprint) before doing the calibration.
- 250°C
- Around 2 to 2.5N
- Add Mosquito Boron Nitride Thermal Paste improves heat transmission/reading around the nozzle thread. Make sure to not get it INTO the nozzle
