Hi,
I want to convert my bottom axis Axis, dual motor to belt drive.
I have 2 nema 23 4nm motors to fit on this axis over doubling the torque.

I have 2 questions
What T5 pulley should I use?
What T5 belt?

Will this Belt do?

And are these pulleys even suitable?

I see grubscrew and think 4nm is a lot of torque to hold on 4 grubscrews.
