Bits were ordered for milling new brackets using the shop's CNC. With the shop's lasers temporarily out of commission, this represented the only option for stronger brackets within my reach, without outsourcing. An attempt was made at milling a bracket out of aluminum using the shop's CNC. Unfortunately, the bit began slipping halfway through the job (my fault), and the job had to be halted. Having lost confidence in the idea, I cleaned up and unbolted the aluminum plate from the waste-board, effectively rendering that part unusable.
HDPE remains an option in the future, though COVID-19 has changed a lot of things.
Shipping from China has become intolerably slow. It was slow before, but it's a matter of months between ordering and receiving now. As thicker brackets will require longer screws, I will probably go forward with the brackets I have, and attempt to build a usable machine, then consider upgrading the brackets... even if it's just a matter of farming out 3D prints to those with larger printers. The laser cutters may again return to functionality, in which case, that's another option to consider.
The very very last of the ordered parts from AliExpress, however, have finally arrived. So all components are present now.
It is time to start plotting out the lengths of the aluminum extrusion segments that need to be cut.
