Hi All,
I was looking at Alberto's excellent machine in the "Gallery of Machines" (Italy Homebuilt).
He's using smooth idler wheels on all of his axes: (

Does anyone have any pro/con to doing this? It would save some money.
The only things I can think of would be deformation of the "teeth" on the belt, and maybe more noise.
