Hi all.
I'm a beginner working on my first project and I have a somewhat basic question.
I have two gt2 pulleys:
Pulley 1: 36 teeth
Pulley 2: 60 teeth
Center distance: 51.5mm
Belt: Closed 200mm (100 teeth), 6mm width
If I drill the holes so that the distance between the pulley centers is the calculated 51.5mm, will there be sufficient tension on the belt?
Or should I drill slits instead of holes to allow for tensioning? If so, how long should I make the slits? Is 2-3mm long enough?
The frame material I'm using is 6mm aluminum 6061 and the stepper is a geared NEMA 17 with 6mm shaft (hence the weird ratio, I only found 6mm bore pulleys with either 20 or 36 teeth)
The second pulley shaft is 8mm.
Thanks for your help.
