I choosed to connect both z-stepper with a timing-belt-loop because of some runtime-differences after a while.
Mostly these belt-loops havn't the right length you need, so take this solution. My timingbelt-loop-tensioner spreads the length to fit the loop.
Add a simply GT2-Idler and a M3-screw as axis and adjust the tension of your loop-belt. For some cases, you have to do some designcorrections because there are different stepper-sizes of the dual-shaft-stepper-motors. Sometimes, a scale in Y is practical.
To make designchanges, I add the original FreeCAD-File.
Have fun.
