My understanding is that all of the v-wheels should be tight enough that they can’t be turned freely with your finger but not tighter - ie the eccentric nut at about 11 o’clock. But the bottom front wheel on my right side Y-axis spins freely regardless of how tight I make it. I tried loosening the back bottom eccentric but to see if it was just tilting to far up but it seems I just can’t get it tighter. This is from fall 2015 that I recently upgraded to the XL so this v-wheel and assembly is two years old. Not sure how I can fix (or even if I need to? Or do the bottom v-wheels just need to sit snugly around the extrusion but not necessarily so right they don’t soon freely?)
Thanks for any advice.
