@jay_s_uk This is of course also possible. However, as I believe that the weight of the Z-axis with spindle motor is primarily responsible for the lost steps, I rule this out for the time being with a counterweight. Then I will consider whether the motor dimensions are at all practicable.
Here is a photo of the CAD model to give you an idea. Yesterday I made the first chips in Styropr with the real milling machine.
