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.
