S3M Timing Pulleys on stepper

Help & Support Robot Parts

Hi,
I’d like some advice on using S3M Timing Pulleys with a stepper motor turning up to 300rpm, max torque 0.55Nm. I’d like to use a 42 tooth on the stepper, and a 15 tooth on the over hand, in order to increase the speed by the same time. Is it ok? Or 3mm is too small and I will face sliding?
Thanks and regards!
Olivier

For others, S3M 42 tooth timing pulley: https://www.robotshop.com/en/s3m-42-tooth-timing-pulleys.html
The bore of this is 3mm and there is a set screw to keep it in place on the shaft.
If possible, have a flat on the output shaft for this set screw.
Don’t see any issue with the setup you described, provided the belt is properly tensioned.
