Bad edge
Hello I have problem with bad edge when it is doing overhang without supports. It is under 45 so it does not need supports.
I'm printing with Original MK3 (not kit)
Does someone please know why it is doing this?
First two pictures are from Silver Prusa PLA on 0,1.
Last one is colorFabb XT on 0,15 and standart settings from Prusa Slic3r
Re: Bad edge
I'd still argue it's overhang... For the first piece if it were me I'd rotate it 90 degrees on the bed, it will print faster and be stronger, though I'm not sure what the piece is for. I'm no expert but I find rounds are less forgiving than chamfers when printing overhangs

Hi Edward,
I assume you are printing outer perimeters after the inner perimeters, if not, try it!
are you using 100% cooling? this will reduce sagging.
you could reduce the print speed, and temperature for the lower curves to reduce the sagging,
you could try variable layer height and use thinner layers for the lower part of the curve.

Re: Bad edge
I've been noticing the the back of the printer does not get enough part fan cooling and tends to have more sags and "rougher" prints than the front.
If you don't have the fan cranked up, I would try that and also lower your nozzle temp like 5 degrees.
I saw a part fan nozzle that was split blowing air from the front and back facing the tip (versus the stock crescent moon shaped one), but I lost the link and wanted to try it.
Re: Bad edge
I'm not sure where to begin.
I see many potential issues.
I'll start with the most likely, going to least likely.
1. Poor cooling.
2. Too hot on the nozzle.
3. Too fast of print speed.
4. Over extrusion.
I'm not really sure though.
