Has anyone thought about printing narrower lines in order to get sharper corners? Once Linear advance or Pressure advance is activated, you don’t get bulging corners anymore… but can we do better?
Has this been implemented anywhere yet? Does it have a name?
Exactly. And the PA tuning that Ellis has is great for tweaking it.
Maybe my sketch doesn’t make it clear. I mean to intentionally make the extrusion narrower and make the print path go outwards to compensate for the narrower extrusion.
Pressure Advance does it. It reduces the extrusion at corners, accounts for coast speed, etc.
The actual extrusion or the extruder input? Of course it will also reduce the extrusion if badly tuned, I guess that’s not the idea though. PA is also needed for straight lines with variable speed. It does help with corners but would need additional path corrections.
As shown in my sketches below:
