Describe your issue:

Now I have a fault on z movement. The default position on my printer is z in the middle of the printer, means 400mm down.
Z hase to move upwards to 0 and during start of reference or print the z stops and makes awful noises.
If I move the z to example 20mm up and start print or calibration after, it works fine.
So only on a big movement it gets faulty. ?

[printer]
kinematics = corexy
max_velocity = 150
max_accel = 1000
max_z_velocity = 50
max_z_accel = 50

For a lead-screw driven system the max_z_velocity is much too high. Try something along the lines of:

[printer]
...
max_z_velocity = 15
max_z_accel = 120

works again, thx!
