    I just wanted a quick print, so in this I'm using PETg (spoolWorks Edge), pressure advance is calibrated but I haven't calibrated my temperatures - I'm just using an arbitrary 245C. I'm printing infill / inner walls at 60mm/s and outer walls at 30mm/s and my filament wasn't even fully dry. I didn't take any care in this part as it was just for a test fit.

    I needed to print a part with a counterbore for a screw on the underside and I forgot to enable scaffolding - How did it turn out? Here's a picture of the under-side - To be clear the surface I'm showing was face-down on the bed.

    This isn't a nice fast bridge between two points, Cura (v4.5.0) decided to work inwards at 30mm/s and then did the final inner circle at 60mm/s - All supported by just the hot filament to the side and nothing but air below it.

    Why even bother with scaffolding? I'm floored by this result.

    Nothing against scaffolding but if you print mostly PETG you will love the fact that PLA doesn't stick to it well. Its an amazing support material.
