PA tuning pattern fails
I'm trying to fix some PETG printing issues where the thin lines on infill start a spaghetti, I also need to do a print with only one wall where I'm having issues of blobs making it fail.
I think I need to tune pressure advance and retraction perfectly but I can't seem to get there.
When I do the pattern method the start of the line is very difficult. Anyone knows of any tips and tricks to get the extrusion to start and stop perfectly? After doing the blob prime the first line takes a cm or 2 to start extruding. Should I use the deretract setting?

I'm thinking the auto generated test values from orca are bad. It does the test very slow, and with z hop. IIRC ellis from the tuning guide said to do this test without zhop and with actual printing speeds
Trying that now
are you sure your first layer squish is good?
I'm using beacon contact so it's as good as I've ever gotten it
I got past this though by disabling retraction iirc and upping the temperatures. After tuning the PA I put back 0.5mm retraction, sometimes I get some underextrusion in the prints too but if I make sure it doesn't start a line on the outer layer I should be fine
