How tight should v-wheels be? - The Shapeoko Forum

Just started assembling my SO3, and I have a question about the eccentric nuts and the v-wheels on the Y-axis. It says the gantry should move freely, without binding, grinding, etc. When I tighten down the eccentric nuts at the bottom of the Y rails, it gets pretty tight. I would say it moves "smoothly", but definitely not "freely".

Strategy and error analysis for machining the designed ...

It shows a structured grinding wheel rotates at a grinding velocity (v g) and the workpiece is fed at a feed rate (v w). The proposed model assumes that while the grinding wheel starts moving, each grit point rolls over the workpiece surface as a summation of the rotation and translation motion through a perfect cycloidal path (see Fig. 2b).
