This remix is based on the Bambu Lab P1S Starting G-code (1 Minute Version 2.0), adapted to better suit my printing workflow.

Start g-code DEPENDS on the end g-code where is cleaning of nozzle while cooling down.

Use at your own risk!

Modifications include:

• Extended start code: added a short scrubbing against the bed routine (shorter than in the original) to remove any filament leftovers after the end code cleaning.
  • This improvement allowed me to return to the original Z offset settings: -0.04 for textured PEI and 0.00 for other plates and have perfect 1 layer each time even when shuffling filament types
• Modified initial purge line: original purge L-line is modified with a ~2mm shorter return pass —  to prevent the nozzle from running into the blob (extruded at the beginning) and dragging it into the print area.
• Updated end code: extended the nozzle cleaning cycle — it now cools down to 70 °C (instead of 60 °C), cleaning every 5 °C. The chamber fan is also enabled during this process to help remove fumes through the carbon filter.
