Bug: xxxx in 3d printing

[rkoshak]

🐞 bug report

Affected Version(s)

The issue is caused by any version after 4.0.4-beta3

Is this a regression? (optional)

Yes, the previous version in which this bug was not present was: 4.0.4-beta3

To Reproduce

Steps to reproduce the behavior:

1. Start a 3D printer project
2. Import one or more STLs
3. Click on "Generate G-code"
4. Slicing happens almost instantly and it gets stopped at "Previewing G-code" at 0.5% or 1%, never progressing to completion.

A clear and concise description of the problem...

Exception or Error (optional)

None apparent.

Expected behavior

I expect that the STL gets sliced and the G-code preview is generated. From there I expect to be able to export the gcode file or push it to the Snapmaker over wifi.

🌍 Your Environment

Platform:

- Operating System: Debian Buster running on the Linux Development Environment on a Pixel Slate Chromebook
- Printer: Snapmaker A350T

Since we can't reproduce it. Could u send us the project file to help us reproduce it ?

Here is a screen shot showing it stuck at 0.5% for Previewing G-code.

I put a broken project on my google drive.

All I did was upgrade to 4.1.4, created a new 3D project, added a random STL which I've successfully printed before and clicked "Generate G-code".

I have the same issue with custome settings and materials. Stuck on 13.9%

This is happening when the object is scaled down to 50%. I have tested scalling up to 51% and G-code is generated correct Right now I can't print anything, it stuck at that point and that's all

Z_Offset_Test.zip I have attached the test STL file
