If you run full, maybe try half-coil would give better results. It gives less torque but way more speed. Or if you are half coil and need more torque, maybe try full coil.

What is the problem with your current steppers? Speed? Torque? Both?
The X and Y are good. The Z is very heavy and I have had times when it would loose steps because it could not move
up and down. I had a time when the Z could not hold itself up.. I fixed this with springs. I had read on this forum that
people used springs and gas struts on the Z to help. I just decided I would fix Z. I have an 8 wire motor wired as a 4
wire.I am no pro just a hobbyist and retired looking for all the help I can get. Thank you for the reply.
