NEMA34 upgrade (lemmy.ml)

Upgraded from a NEMA24 to a NEMA34.

Before going out and milling or buying it in metal it is always a good idea to testprint it.

Probably will use the plastic part for a while as 3mm wall-thickness PETG seems might already be good enough.

Biggest concern for me is creep over time.

Thats why you go CF. It drastically increases the MoE of most plastics and they will not have nearly as much creep; you're pulling mostly against the rigid fibers in the plastic matrix, and not loosely interlinked polymer bonds of plastic alone (which will disconnect over time and causes creep). As long as your service temp is not extremely high (>60C).
