One more question, I've been looking at gear reduction for the stepper motors / belt system.
Have you ever come across an 80T + 20T combined idler pulley? Or a 60T + 20T combined idler pulley?
Running a 20T GT2 pulley from the stepper to a 60T idler that is connected to a 20T gear turning the drive belt would give me a gear reduction of 3:1, which if I run the steppers at a good voltage could give me better native resolution and better / smoother performance.
Alternatively I've been looking at 16T gears, but the idlers only have a shaft of 3mm, and that seems too small for my liking.
It looks like most people are simply running 20T gears without any reduction for their pulley systems?
Please explain to me how to...
