Printer

Ender-3 V2

How to reproduce

Make sure "use relative E distances" is disabled in printer settings
Calibrate -> pressure advance -> Extruder DDE -> PA Pattern
Export the G-code and check commands of the last layer (after PA pattern finished). Before printing the small cube, the Pa pattern commands will have extrusion values ex. E60, and when staring to print the cube, it will have values ex. E2. In between there will be no G92 E0 Command to reset the extruder length count. Because of this, the filament will retract 58mm, potentially clogging the hotend, and/or the next print will be missing the first few extrusions, since the filament is so far back in the hotend.

Actual results

The slicer doesn't issue the G92 E0 command before printing the last layer of the cube. Weirdly enough, it does issue the command on the layers before. Screenshots attached.

Expected results

The slicer issues the G92 E0 command before printing the last layer of the cube.
