Klipper Nozzle Change

These are the things to do to change nozzle when the printer is using Klipper firmware. Mine is an Ender 3 but should be similar for other printers.

• Heat up the nozzle
• Retract the filament
• Unscrew the nozzle (eg. .8)
• Clean
• screw in the new nozzle (eg. .4)
• Calibrate Z offset using "PROBE_CALIBRATE"
  • Do paper test (TESTZ Z=+.05, TESTZ Z=-.05)
  • ACCEPT
  • SAVE_CONFIG
• Update the nozzle in printer.cfg config "nozzle_diameter"
• Do Screw tilt calibrate
• Do Bed Mesh calibration
• Change Nozzle in SuperSlicer printer settings
  • Select the quality in Print Settings (.20 mm for .4 nozzle)
• Start Printing
