Set screws on Z axis mounts do not work. Ended up not using them. They bulge out the Z axis holder - plastic is too weak. Solutions - modify geometry so that set screw does not make the holder bend out. Maybe make the holder structure stiffer.
Mid set screw for carriages for carriage closure - can it be wider? Need to ream it all the time.
Set screws on motor and idler piece - they have to be pre-threaded with another screw
Big bearings are too stiff if carriages are too tight. Some worked, some were too tight. The grey linear bearings are looser. Must be different material quality.
We mounted Z axes on [2] Pro 3, [1] Pro 2, and [1] Pro. Pro 2 has 4 z axes now for more stability with insulated bed.
We started on making extruders. Heat tightened a couple heaters. Started putting in motor.
