From the release notes for CuraLE 3.2.32:
- Linear advanced enabled for all printers, but not activated
- Must enter M900 K in start gcode to activate. See more info here: > http://marlinfw.org/docs/gcode/M900.html
The K-factor Calibration Pattern has a lot of parameters to tweak some of which are easy and some of which are hard (i.e. I don’t know what the answers should be). I believe it would be extremely valuable if we could get some expert guidance (or even some “worked for me” examples) for each of the LulzBot printers. The comments at the beginning of the generated G-code would make a good template. For example, here’s what I got when adjusting the “easy” parameters for the TAZ 6 (with PLA):

What I need help on is the “Settings Speeds” section and “Settings Advance” section.
