Arachne Wall mode does not use G3 g-code as often than Classic Wall mode

[DzzD]

Bambu Studio Version

1.6.2.4

Where is the application from?

Bambu Lab github releases

OS version

Windows 11

Additional system information

Does not matter

Printer

X1 Carbone

How to reproduce

1- Create a hollowed cilynder, slice it with Classic Wall mode and with Arachne Wall mode.

2- Compare g-code, the classic one use G3 g-codes while the Arachne use G1

Actual results

Classic wall mode :

Full circle made of three G3 g-code

Arachne Wall mode :

Full circle made of tens of very small G1 g-codes

In addition, object size of inner and outer holes differ a lot and then require that X-Y hole & contour compensation have to be adjusted differently depending on Wall mode

Expected results

Arachne should use G3 as well as Classic mode

At least one of inner hole size or outer perimeter should match with the same hole & contour compensation settings

The arachne generate many unnecessary variable width line，and cann‘t fit into one G3 command.
So this is not bug of arc fitting, but issue of arachne.
So next, should check why arachne generate so many variable width line. Maybe because arachne is too sensitive for mesh.
