I think I have solved the problem. Changing the plungerate to 2mm and to 1 mm did not solve the problem. So I tried to increase the current to the stepper by 50 mV at a time. Went from the calculated 340mV up to 840mV, and the problem was solved. The stepper and the driver get hand-warm, even after intensive testing the z-axis, so I am good to go. During testing I also discovered a flaw in the y-axis stepper current. I printed a drawing of the world a couple of times on the same sheet, and Australia almost collided with Africa after five prints. I Increased the current to those steppers also 50mv, solved the problem and saved two continents at the same time 😉
