Mine was tight as well after install. However, with the machine off, I was still able to move the x-axis and simultaneously stop the lower v-wheel by pinching it between my fingers, using moderate pressure. It was a little tighter than how I set my lower y-axis wheels (also using eccentric nuts). I have about 5 hrs of machine time on my XXL now, and haven’t noticed any major issues with the tight HDZ eccentric wheels yet.
Can you stop yours tight wheels from rotating with your fingers when pushing the x-axis? (Machine powered off of course)
