Safety
P1S-GCODE is intended for normal use as a Bambu Lab P1S printer preset.
The provided files contain complete movement, heating, probing, purging, and shutdown sequences. Users who install an unmodified profile do not need to adjust the command values.
The practical recommendations are simple:
- install the scripts in a P1S printer preset;
- keep the original stock preset available;
- watch the first startup after installing or changing a profile;
- use the printer’s normal controls if a print needs to be stopped.
These are ordinary precautions whenever machine G-code is changed.
Each start profile contains a disabled optional command:
; G29.1 Z{-0.02}The semicolon means that the line is not executed.
Most users can leave it disabled. Users who intentionally adjust Z offset through machine G-code should make small changes and observe the resulting first layer.
- A negative value moves the nozzle closer to the plate.
- A positive value moves it farther away.
Returning the semicolon restores the project’s default behavior.
The profiles are open for inspection and modification.
When changing the G-code, preserve the original file and edit one behavior at a time. The commands that most directly affect physical behavior are:
- movement coordinates;
- positioning modes;
- nozzle and bed temperatures;
- probing and Z offset;
- motor-current values;
- material-system blocks.
A separately named slicer preset makes an edited variant easy to compare with the original.
Unexpected plate contact, blocked purging, homing errors, or filament-path errors should be handled with the printer’s normal stop and troubleshooting procedures.
If an edited profile is involved, return to the unmodified project file or the stock preset before continuing the comparison.
