How to change extruder_clearance_max_radius

Bambu Lab P1 Series
1

For reference: https://wiki.bambulab.com/en/software/bambu-studio/sequent-print

Under Related params is an image that shows how extruder_clearance_max_radius is measured. It includes the Lidar which the P1P obviously doesn’t have. Plus, just looking at the parts in Studio I can tell they don’t need to be so far apart.

Is it possible to change extruder_clearance_max_radius? PrusaSlicer supports this but I can’t find a similar setting in Studio.

Edit the printer profile settings.

I found those fields but they’re read only for me.

I changed it by editing C:\Users\...\AppData\Roaming\BambuStudio\system\BBL\machine\Bambu Lab P1P 0.4 nozzle.json. 40 seems like the right value for the P1P.

That is annoying. I even copied the profile to create a new one and it was read only.
I guess that is another benefit of Orca Slicer.

I would suggest that you save your modified version under user (instead of system) with a new name. BBL can update the system directory at any time.

Thanks for the suggestion! I’ll do that.

Has anyone figured out a fix on Mac? I have created a new user printer profile and edited the json file at /Users/[user]/Library/Application Support/BambuStudio/user/3030829350/machine :

{
    "from": "User",
    "inherits": "Bambu Lab P1S 0.4 nozzle",
    "name": "Bambu Lab P1S 0.4 nozzle - Rug",
    "printer_settings_id": "Bambu Lab P1S 0.4 nozzle - Rug",
    "support_air_filtration": "1",
    "version": "1.8.0.13",
    "extruder_clearance_height_to_rod": "40",
    "extruder_clearance_height_to_lid": "150"
}

but when I open that profile in BambuStudio I still see the old values greyed out now with the orange ‘reset’ icons

Solved: Clicking the orange reset icons grabbed my settings from the json file.
