A geared motor is used which drives two belts on the left and right to which the Z-carriages are attached. A fine adjustment mechanism for aligning the carriages is missing. I hope that this isn't a problem and that the alignment via the rotation of the pulley is enough. 2/2
I started to build the Xprinter V2. The drive system for the Z-axis is looking good. The cheap mgn7-rails have quite a lot of play which could be a problem.

I'm in the final design stages of the second version of the Xprinter. This time modeled with @FreeCADNews and #LinkStage3
I'll write about it on the @hackdayio project page: https://t.co/pCjh3LStjy
