Help! noob in over his head with new ("used") Tenlog TL-D3-pro setup :-(

God...

I thought I'd be done soon. I tried to level it but after leveling when I tried to tighten the "fixed" screw that must be loosened to adjust the nut that raises or lowers the E2 nozzle all I could get the damn thing to do was endlessly spin without the slightest hint of threading in or otherwise tightening. It looks and feels as if it is spinning and the tool seems to have a good fit...it just doesn't thread. I definitely don't recall seeing a nut or a space for one anywhere in there but I guess there's nothing for it now but to basically start over and tear the thing down from scratch again so I can try to figure out why the "fixed" screw won't thread. Clogs suck.
