I suggest raising the Z jerk to M566 Z60 and trying again.

The low jerk values means that as the Z height changes with the heightmap the XY axis has to slow down to give time for the Z axis to move since it has to obey the lowest value.

Reducing the first layer speed can also help.

Glad you got it figured out and the driver hasn't failed.

Worked a charm, thanks!

I measured the movement of +1 Z and it was one cm. Also, I think you may be right about the steps per mm as they are x256 micro stepping at 64,000 steps per mm, and instead should be 6,400.
