Corner and seam problem
I have a corner (and Seam) Problem on most of my prints (see pictures) Seams show the same behaviour thicker on the breaking side . I am suspecting my pressure advance settings. Did a pressure advance test with the recommended settings from the klipper github but it was quite hard to determine the right value.
Did the Test with a 0,6 Nozzle, 100mm/s and 0,45mm thickness (as recommended 75% of the nozzle diameter), have a Rapido + Orbiter 1.5 installed.
Doesn't that look like the value being too high? Happy for any help!
EDIT: it is a Vcore 3

It does indeed, slightly too high

I am currently trying this method to determine the pa value: https://ellis3dp.com/Print-Tuning-Guide/articles/pressure_linear_advance/introduction.html
Typical calibration doesn't work for me as it seems
When i calibrate i usually slice the tower at my default print speed and settings and don't slow down square corner velocity
makes it easier for me

I use 100mm/s for the tower and quite thick layers at 0,45
Is the square corner velocity set in the slicer?
can't find it in super slicer or the printer.cfg
for now it seems pressure advance is not just a bit off... ellis' test shows somewhere arount 0,02 instead of 0,045 I use now
No but the klipper PA guide tells you to manually set it to one
0,045 is indeed way too high for a .6

wait... did I oversee this somehow
oh, now I see, thats just one of the two commands you post before starting the print, jeah I did that
harsh-harlequin•2y ago
yeah i don't do that
but this is a better way indeed

It is a bit more work to set it up the first time and a lot of sweat running it (with my finger hovering over the emergency stop) but easier to read
(still don't know why the first layer has huge gaps even though I put in the same Settings from my printer profile)
it prolly sets pressure advance to 0.
or you need to go a little closer to the bed

hope this tool makes it to superslicer/prusaslicer 🙂
Wasn't aware that pa does affect normal extrusion. Thought just for when it stops
pressure advance evens out the extrusion. Although with a 0.6mm nozzle you shouldn't see much impact on lines.
tbh it looks like you're just not close enough to the bed
harsh-harlequin•2y ago
Yeah might be, first normal Print now and it looks a bit far, but still no gaps. Maybe the test isn't to exact with the first layer or I need higher extrusion multiplier there.
Is there a way to close this thread?
or mark is as solved?
