Re: [CAD_CAM_EDM_DRO] Cheap place for new servos.

Thanks for the information, I guess I was looking in the wrong place, all
industrial supplies. Should have looked at what the Gekko drive supplies to
see what servos I could use. Since I most likely will want a reduction, i'm
assuming that means I need to get new belts and pullies for the shoptask to
fit the servo I get?
