What would be a good affordable high tourqe nema 17 for a tmc2100? It will be used on my hyper cube to lift a 400mm aluminum build plate.

How thick, 3mm? Dual motors?
Any 40mm nema17 will lift it.
500x500

@Glen_Beer 1/4in with dual lead screws

@Carter_Schunk for sure with dual Z’s you won’t have a problem. I’ve seen builds using one with belts that lift steel bed with everything on it.
This printer is using steel plus aluminum plate and 4mm sheet and has no problem.
.9 degree however the other 3 in the pic are using 1.8 degree 17’s.

@Glen_Beer Would these work, I salvage them from an old printer and just assumed they wouldn’t

Nice printer. I have a single standard nema17 using belts and three lead screws. The lead screws are 600mm single start 2mm pitch. The bed frame is 2020 t-slot with a 520mm x 530mm x 3mm aluminum (7075) plate on it. It works beautifully. I needed to reduce the acceleration to prevent skipping but that gives it a very cool slow start and then it gets up to speed as it climbs.

@Carter_Schunk yes. In series. They don’t need a lot if the pitch of lead screw is not to aggressive. Extruder works much harder.
