I tried the new Pressure management with a K factor of 8. When used in combination with retraction enabled (10 mm) , the filament was retracted significantly multiple times until it was half way up the bowden tube before I stopped the print. This occurred while laying the perimeter of the first layer.
Resliced without pressure management enabled and everything was okay.
Unit test for pressure advance. #2470
@ccavanaugh, I failed to reproduce the issue. I also wrote a unit test that succeeds.
Could you provide more details for reproducing that? STL file and configuration (File -> Export config…). Thank you!
Wait - I can reproduce it...
Bugfix: pressure regulation accumulated too much retraction and didn'…

Okay, I fixed this and added a regression test. Thank you!
Thank you!... Will try again after the next release. I'm tying to run nylon with heavy retract and looking forward to seeing if it improves print quality.
Terrific, had this problem too, massive retraction (and I couldn't see it in the gcode for some reason?)
