Thanks printbus, yes it is finicky. There wasn't anything in the guide about this. I did do it as you mentioned on my initial build, without the leveling step. I noticed the freely spinning wheel and redid it buy loosening the x brackets and then adjusting the cam wheels, then leveling and tightening it up. I need to do it again I guess and take a bit more time. I really like how the MTW Mendalmax 3 is put together. Their x-axis and extruder mount system is very robust and makes adding dual extruders effortless. I see many correlations to the new pegasus printer and the MM3.

I would look for inspiration there if making changes. I have seen some pretty amazing prints from those. It has taken me many hours of tinkering and tweaking to even come close to the results a colleague is getting from his MM3.
