Shipping - 3:10 hr to pack and ship. Included taking an existing extruder. No quality control on the electronics. Included cutting 17 rods (2 extra). Up until final package taped up, ready for address label. Included dismounting a frame and printing missing belt tensioner, and scavenging corner pieces off existing frame build. Corner pieces replaced as prints finished. used 105% corners for first time, they work better. Packing list checkoff was about an hour - most was prep and rework of packing list and rework of part count for monolithic Universal Axis. Still in process of shakedown. Close to complete documentation for training and hiring, needs detailed time sheet for financial projections.

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.

Set screw on the Z axis motor piece strips out. Bottom m6x18 provides good grip on the z axis rod.

4 people total - 2:24 starting at noon - 2:24 hours to do 4 frames: 1 small, 1 Pro 2, 2 Pro 3, with mistakes and taking things apart.
