Is there an existing issue for this problem?

I have searched the existing issues

OrcaSlicer Version

2.3.2-dev Build bd6cfd6

Operating System (OS)

macOS

OS Version

15.6.1

Additional system information

When using the normal Orca Slicer with my Snapmaker I get weird print times, But ONLY when coloring / painting my models by hand. If I don't use different colors OR the models are pre-painted, everything works normal.

But as soon as I paint one place, the print time goes crazy. Like 86383138138138123 hours. (As more I paint as higher the numbers get). When I try to print it, the printer just pauses before the first color swap.

I guess the error lays here in the gcode in line 886 or 888? These numbers look suspiciously high...

With different nightly builds I get different numbers, so some things seem to change in the nightly builds. For me it was enough to add an stl, add some text to it and choose a different color for the text.

Printer

Snapmaker U1

How to reproduce

For me it was enough to add an stl, add some text to it and choose a different color for the text.
