Hi, my problem is, that changing my pressure advance value doesn’t seem to make a difference. I’m running a Bowden setup with quite a bit of play in the pneumatic hose connectors. In the 2 photos you can see me first trying a pressure advance value of 0-1 in 0.02 steps and the second image I’m trying a value of 1-2. At 1.6 and beyond the extruder started skipping. Any clue what I could do? Or should I just leave the Pressure advance at 0?

After messing around a bit with the settings I found out that my speed and acceleration were set to high.
