How to change the default pause settings?

[JonRaymond]

Looking at your code part of the issue I think is that the M400 and U1 have to be together on the same line as the U1 specifies what the M400 does.

You can’t change where the M400 U1 parks but you can use it to pause till you are in front of the machine and then, move the nozzle to the front and delay a certain amount of time (for you to clean it) and then resume printing.

Example:

M400 U1 ; Pause print and wait for interaction
G0 X128 Y0 ; Bring nozzle to the front (rapid)
M400 S30 ; Pause for 30 seconds
G28 X Y ; Home the X and Y axes in case they were upset

FYI - A great Bambu reference for gcode can be found here.

Edit: Sorry, I actually did look at that thread for a while, and it helped me set up spaced “auto-cleaning,” but I still can’t seem to manually press pause and bring the head to the front. The only reason its important to me is that I can’t access the printers outside of work hours, and would like to be able to clean them quickly by hand when necessary.

The pause gcode section is only for manually inserted pauses when you slice the model. It will not add to the “pause” cycle from the printer/slicer/handy while printing.
