Which Stepper to use for Model SP6

Hi there,

I have been printing 3d clocks for about a year now all of which I have designed and built from first principles, most of which have been electric using Arduino Nano, and the 28BYJ-48 stepper. All have been working fine. However, the stepper motor used is not very accurate and giving +or- one min in 24hours.

I have recently downloaded the files for Steve's SP5 I must say the documentation is excellent.

I will download the SP6 in the next few days but i have one question for Steve. What is the best stepper motor to use as there are many nema 17 motor to choose from?

Would i be correct in selecting model # 17HS 13-0404s1. to run the SP6 ?

Any help and advise would be much appreciated

Many Thanks

Alan
