@iPeel Yes, that length Bowden tube will always cause issues. I'm still surprised that you needed much, if any, pressure compensation with 0.8mm nozzle.

How do you know you get missed missed steps with high extruder jerk? Especially when using an 0.8mm nozzle. Have you run M122 and if so, what was the result? I'm somewhat mystified because as I said before, extruder jerk never gets applied unless it is silly low.
