I'm really interested in trying this, as I believe my hobbed bolt extruder has great nonlinear behavior that is really visible on my parts. So I would be happy to test this. Could you do a pr for this over at superslicer too? They might merge faster as they are quite open to advanced config options. |
You can very easy test it with gcode.
SuperSlicer has another code for GUI, so this PR should be ported (nothing terrible so). I suggest open FR, Merill reacts very fast. |

I made a comment on an already existing feature request.
I mean can you please help me get a version of prusaslicer with this PR implemented, so that I can do my own slicing to test this feature? |
I can build it, but it's safer if you compile it from sources. Anyway, did you test exact underextrusion amount? |
|
Since merge of MarlinFirmware/Marlin#26824 NLE in Marlin works properly, I guess this PR could be closed, as it's better to use firmware NLE. |
Slicer implementation of Nonlinear extrusion MarlinFirmware/Marlin/pull/26127
I tried this Marlin feature, but it didn't work for me. Also it's more easy tune these values in slicer.
Last option shows extrusion amount that was sent to extruder motor. It exceeds expected amount to compensate underextrusion caused by gear slippage:
Default estimation:
What is issued to gcode:
With my MK8 0.6 I have following compensation curve for PLA/205C:
Now model weight is exact as it should be given correct filament density.
