I would like to ask the "Pulley People" a question:
Are regular pulleys with set screws OK to use on smooth shafts with no keyway or flat sides etc.....? All 3 of my motors have a smooth round shaft, as well as my Z-axis shaft, and my X-axis pinion shaft. Not sure about my Y-axis shaft cause it's in the mail.
Also, XL belts are only about 1/4" to 3/8" wide. That doesn't seem very sturdy. Would L belts at 1/2" wide be overkill?
Thanks for any reply..............Sam
