Are you using Canvas or Prusa Slicer with P2PP ?


I am using P2pp with Prusa Slicer

I had the exact same problem! Printed with one color and had two failed prints in the same spot. I chopped it up to some sort of bug. I wanted to print through Palette 3 to build on the calibration history and utilization of the filament runout detection. I hope this gets fixed soon.

This could be an issue with P2PP not providing correct gcode to the Palette.

I would post your problem on the P2PP Facebook to see if anyone in the community has a solution and post a issue on the P2PP github page.

Same issue here; using Palette 3, Creality Ender 3 v2, SuperSlicer, P2PP.

I’m attempting my first print, with a single color, and I get the 149 error on initial loading of the filament. I’ve tried various printer and print settings but no luck. Not much about this from Google either. I’m stumped, hope someone finds a cause and a solution.
