Yikes. After being idle for several years, I am getting our Shopbot PRS Alpha going again. Today I removed all the v-wheel covers to clean and oil the felt. I found one of the V-wheels on the gantry is not riding on the rail, it's about 1/16" above it. The other 3 wheels seem fine. I don't believe these are adjustable (like the eccentrics on the xy car).
Reading page 3-4 on the setup guide, it seems to say to adjust the feet until the wheels are running on the guides. Is there another option?
