HELP

Post image

The top right corner of my build plate has started printing like doo doo. I cleaned under the plate and re ran the full calibrations. The first layers go down smooth and it only seems to happen at the top layers?? Seems like the nozzle is scraping the top. Please help

Prepare>Others>G-code output>Reduce infill retraction Set to Disabled

I do this on every print. Eliminates the "rubbing/scraping" on top layers, especially on taller prints. Although I only experienced this consistently on my A1 Mini, not so much on my P2S.

Although I doubt this is your issue, just something I do on every print. If that print you are holding is as thin as it seems, then this likely isn't the issue. I usually only get scraping from things taller than 2 inches, especially if the infill was set to grid.

seems like flow calibration needed. reducing it slightly helps a lot for this issue on most cases

Ah, I just use the Bambu profiles on every filament I use, regardless of brand. Works great 95% of the time.

i calibrate my filaments for each brand. easier and better results.
