When I first printed the foldarap there was no Z endstop adjustment bolt. I reprinted my Z sliders due to some play causing z wobble and want to make use of the z adjustment. How exactly does the adjustment bolt go together? I see no captive nut trap or anything else to hold the nut so the bolt can adjust up and down.
In fact the bolt is screwed in the plastic, either by the top (it allow an easier adjustement on the fly), or by the bottom (it may be easier to screw it in if the z-slider is already on the foldarap)
