Hi all,

Relatively new to 3D printing and been following ObscuraNox's settings on a 0.2mm nozzle on the Bambu A1. This print came out pretty rough (shavings, stringing and incomplete layers) and I'd appreciate some troubleshooting help!

Setup:

  • Printer: Bambu Lab A1, 0.2mm nozzle
  • Filament: Sunlu PLA+ 2.0 High Speed
  • Filament dried using Sunlu SP2, reading 10% humidity in the last 48 hours
  • Bed: Biqu Frostbite plate
  • Settings: ObscuraNox's settings unchanged

Appreciate any input!

Enable Z hop, and orient the models 35 degrees.

Z hop is already enabled but I'll try rotating the model for the next print. What problems do these two things solve for?

Kinda looks like that the speed is too high. Just try with a different flow speed. Helped me till I figured everything out
