Linear Advance
Hi all,
I've read very little here about the "experimental linear advance" option, but feel ready to embark on the next adventure.
I have fixed my MMU now and think it works as intended. My problems were a combination of damaged/poor tolerance heatbreak and friction in the MUX. After installing Seths printed variant and getting a new heatbreak from PR the very first print was a success using default settings (but PLA temps reduced 5°). The machine is reliable (24/7 MM printing for a week with nice results) and I my extruder/filament/extrusion width are dialed in perfectly. Overall print quality is definitely not worse than before the upgrade, maybe even slightly better.
Can I expect to flip on LA and get nice prints?
Is anyone using it successfully?
I noticed the preset says K=100 but in the gcode K=200, why?
Cheers,
Nils
Re: Linear Advance
I am using linear advance with the MMU and have had zero difficulties yet (2 weeks). I think you should be ok. As for the disparity, I don't know personally. I saw the K200 in the filament section for anywhere the MMU was used. I didn't change any of that and stuck with what was in the latest default package.
Re: Linear Advance
Linear advance works well, and you can push up your printing speed. K=200 is correct for MMU. Not sure where you saw 100?

Re: Linear Advance
Ah, it says 100mms in the profile and that's the default infill speed. Got that mixed up.
EDIT: It works very well indeed. For my test model, 100mm/sec were a bit optimistic. With 80mm/sec the results were comparable with the non-LA profile but a noticeably faster. No stringing or drip problems at all, no blockage.
