Updated arc fitting pop up to clarify that this option should not be enabled for Klipper machines

[igiannakas]

Description

Klipper does not natively support arc commands at the motion controller level. Hence enabling arc fitting on Klipper is detrimental to print quality as line segments are converted to arcs in the slicer and back to line segments in Klipper.

The revised pop up wording clarifies that this option is not recommended for Klipper printers.

Fixes #5297
Fixes #4216

To make this even easier:
Why not just disable and hide this feature once you set G-Code flavor to Klipper? 😊

Because for some reason someone may want to use it I suppose…

From Orca 1.6.1 to 1.6.4 ( https://github.com/SoftFever/OrcaSlicer/releases/tag/v1.6.4 ), there was a note in the release not page encouraging people to enable Arc fitting.
But I totally understand your point, I will probably stop using it in my profiles ;-)

No that note is recommending enabling support in klipper because some non extrusion moves use arc commands. For example spiral z hop uses arcs. As this is not a printing command it doesn’t matter that arcs are used. It’s not recommending that arc fitting is enabled in the print settings in the slicer ;)

Understood ! Thanks !

I totally agree here.
Enabling ARC fitting for Klipper is not recommended.
