Re: [CAD_CAM_EDM_DRO] drive belt idler

I found just the opposite, There is a minimum diameter allowed for each type of belt that can be used on the back side of it for a
tensioner. The other inexpensive options like cam followers were too small. The belting I used was bigger though, so hopefully you
will fair OK.
Cheers,
Brad
