Hi, i’m currently assembling their kit but i don’t know what i’m doing wrong, the kit is the 15mm one with 15mm belt and 97mm wheels, i am using a spacer on the backside of the wheel and that clears the wheel from the motor pulley.
but what i don’t get is how to make so the set screws on the motor pulley wont hit the belt when it’s spinning. am i doing something wrong?
It will most likely have a small amount of play, but it’ll work. I use both, and I’ve had the set screws come loose before. The board still worked fine, but you could hear the pulley rattle a bit. Not a big deal. As far as slipping off the axle, your belt will prevent this if it tight.
