Printer

Creality K1 Max with Co Print Multimaterial upgrade

How to reproduce

Change directory to "~/Downloads"
Download OrcaSlicer flatpak from https://github.com/SoftFever/OrcaSlicer/releases/download/v2.3.0/OrcaSlicer-Linux-flatpak_V2.3.0_x86_64.flatpak
Install OrcaSlicer systemwide available with sudo flatpak --system -y install OrcaSlicer-Linux-flatpak_V2.3.0_x86_64.flatpak
Starting OrcaSlicer via command line (to produce error messages) with /usr/bin/flatpak run --branch=master --arch=x86_64 --command=entrypoint --file-forwarding io.github.softfever.OrcaSlicer @@u %U @@
During setup select "Co Print" as printer as well as filaments "Co Print PLA","Co Print PETG", "Co Print ASA" and "Co Print TPU"
After setup define a klipper printer with IP address
Close OrcaSlicer
Reopen OrcaSlicer

Actual results

After starting OrcaSlicer with defined printer, it shortly shows the main window and then closes immediatly.

Expected results

OrcaSlicer starts up and the user can create, edit and print projects in multimaterial.

Change directory to "~/Downloads" 2. Download OrcaSlicer flatpak from **https://github.com/SoftFever/OrcaSlicer/releases/download/v2.3.0/OrcaSlicer-Linux-flatpak_V2.3.0_x86_64.flatpak** 3. Install OrcaSlicer systemwide available with **sudo flatpak --system -y install OrcaSlicer-Linux-flatpak_V2.3.0_x86_64.flatpak** 4. Starting OrcaSlicer via command line (to produce error messages) with **/usr/bin/flatpak run --branch=master --arch=x86_64 --command=entrypoint --file-forwarding io.github.softfever.OrcaSlicer @@u %U @@** 5. During setup select "Co Print" as printer as well as filaments "Co Print PLA","Co Print PETG", "Co Print ASA" and "Co Print TPU" 6. After setup define a klipper printer with IP address 7. Close OrcaSlicer 8. Reopen OrcaSlicer ### Actual results After starting OrcaSlicer with defined printer, it shortly shows the main window and then closes immediatly. ### Expected results OrcaSlicer starts up and the user can create, edit and print projects in multimaterial. ### Project file & Debug log uploads No debug file was created. ### Checklist of files to include - [ ] Log file - [ ] Project file ### Anything else? _No response_
