OrcaSlicer¶

Configure OrcaSlicer for optimal use with Mainsail and Klipper.

Thumbnails¶

To display thumbnail previews in Mainsail, you need to configure the G-code flavor and thumbnail settings in OrcaSlicer.

1. Open the Printer Settings (the button behind the printer dropdown in the top of the sidebar)
2. Navigate to the Basic information section
3. Set G-code flavor to Klipper
4. Set G-code thumbnails to 32x32/PNG, 400x300/PNG

Layer Information¶

To have Slicer based layer information displayed in Mainsail, you have to add some lines of G-Code to the Slicer Printer Settings. Open the Printer Settings (the button behind the printer dropdown in the top of the sidebar) and then Machine G-code and set these lines of G-Code:

1. Start G-Code (before your start G-Code):

   SET_PRINT_STATS_INFO TOTAL_LAYER=[total_layer_count]
   

2. End G-Code (at the last line):

   ; total layers count = [total_layer_count]
   

3. After layer change G-Code:

   SET_PRINT_STATS_INFO CURRENT_LAYER={layer_num + 1}
   

Exclude Objects¶

OrcaSlicer has native support for Klipper's Exclude Objects feature and adds the necessary G-Codes to the generated G-code file. You just need to set the G-Code flavor to Klipper.

1. Open the Printer Settings (the button behind the printer dropdown in the top of the sidebar)
2. Set G-code flavor to Klipper

Upload to Printer¶

Upload G-code files directly from OrcaSlicer to your printer using the built-in upload to Moonraker.

1. Open the Physical Printer dialog (the button behind the printer dropdown in the top of the sidebar)
2. Set Host Type to Octo/Klipper
3. Enter the Hostename, IP or URL of your Moonraker instance, e.g., mainsail.local
4. (Optional) Enter the Device UI URL of your Mainsail instance, e.g., http://mainsail.local
5. Click on Test to verify the connection

After configuration, you can upload G-code directly to your printer using the Print button in the top-right corner of the OrcaSlicer interface.
