Is there an existing issue for this problem?

I have searched the existing issues

OrcaSlicer Version

2.3.0

Operating System (OS)

Windows

OS Version

All

Additional system information

No response

Printer

Bambu A1/A1 mini

How to reproduce

fresh install of OrcaSlicer, Fresh install of BambuStudio, both with default A1 profile
add two boxes to plate, size them to 180mm x 95mm x 20mm
set Print Sequence to By Object

Actual results

BambuStudio will not let you slice the file, as the objects cannot get far enough away from each other, which is correct, because it's a hardware limitation.

Orca will let you slice the file, but if printed, it will cause collisions.

Expected results

no collisions

Project file & Debug log uploads

A1 Radius Issue.zip

Anything else?

I believe this may be an issue between how orca and bambu handle "extruder_clearance_radius" vs "extruder_clearance_max_radius" in the machine profile, but am not sure.
