Importing PIF profiles into PrusaSlicer

[MagicalMe001]

I imported the Ellis PIF profile into PrusaSlicer 2.6 and it completed, with just a few suggested changes.

I had problems printing with it though (during bridging) with the error:

Move exceeds maximum extrusion (10.681mm^2 vs 0.640mm^2)
Move exceeds maximum extrusion (10.681mm^2 vs 0.640mm^2)
See the 'max_extrude_cross_section' config option for details

I know that I could change the max extrusion limit but that seemed wrong to be so much bigger.

I went to the prusa gcode viewer and looked at the layer where it quit printing and switched to show "Volumetric Flow Rate"


You can see huge flow during the bridging.


To resolve it, I went to the PrusaSlicer Print Settings tab, and clicked on the "Compare Preset with another" button at the far right on the top



I loaded the Standard Voron 2.4 profile along with the imported PIF profile.

The one thing that stood out was the bridge flow ratio was 0.8 in the standard profile and 85 in the PIF profile. So superslicer must be using percent while prusa is expecting a 0.0-1.0 value.


I changed that and am good to go!

Interesting. Out of curiosity, what drives you to use PrusaSlicer, rather than SuperSlicer?

Line *width* is handled very differently in SS vs Prusa, and normally go insane when cross-importing. I would suggest double checking that the line widths its trying to use for all the basic feature types are remotely correct.

The usual culprit is the bridge flow ratio which gets mangled readI guess the SuperSlicer profile. 85% in SuperSlicer turn into 8500% in PrusaSlicer as that uses fractions (0-1) for flow rate.

Sure - I was looking for Organic supports - so something that needs the Prusa 2.6 baseline.

Thanks. I will check that out.

Thanks for the pointer. I will go double check it. I am getting some lines of underextrusion (horizontal gaps) so that may be it.

I just imported Standard one to my PS 2.6.1 version and testing ... increased little bit speed ... so far I got much better quality and faster prints than I got from my tests from SS and OrcaSlicer 1.8 .... I'm supper happy so far !
