Hello,

On my F350 with dual extruder I was trying to calibrate LA but do not see any difference in a range of 0.04 to 0.2, I am running the latest beta fw (Marlin SM2-5.2.1) with vibration compensation and direct connection via wifi to orca slicer, could any one confirm that LA working or not?

T0 when I do not manually assign extruder, just K900 K value, T1 with manual adjustment, no difference between them and within them.

Another question, is K900 T0/T1 actually working? Right now I am modifying G code to assign K value to correct extuder because slicers cannot do it.
