There is just no easy way to put this but I am just not happy with the how choppy the z-axis movement is with only one lead screw and motor. I am halting a lot of progress in the printer by just not accepting it needs two lead screws for smooth motion.
On another note, my main competition has been the Prusa Mini and I recently learned while working on some that they do not use dual gear drives. It's not the end of the world for them but their extruder system is very likely to strip filament and clog the extruder in a jam requiring a near complete disassembly of the system to clear the jam.
In other news, I ordered some new weather foam strips for masks and I have been printing a number of masks as test prints.
Cheers!
