Hi, I am interested in tuning linear advance on my printer running RAMPS with Marlin 1.1.9 release
I tried generating test patterns using this page: [marlinfw.org]
The first one I did in the default range 0-2, then I tried 0-10, and even 0-100, and I never see the effect of under/over extrusion going away or reversing.
Does this not work with higher acceleration values? I have 3000 mm/s^2 accel on XY and 10mm/s jerk. The extruder is a greg's wade 1.75mm (no bowden).
I was testing 15mm/s to 40mm/s speed difference.
Is it possibly some conflict between extruder vs XY accel / jerk?
edit: Is there a setting I missed in Configuration.h to enable this in the first place?
Also should I be running the 1.1.9 bugfix instead? I never quite understand why the branch with fixed bugs would be the one that is cautioned *against* using on the download page.
