Review on Befenybay 2020 Upgrade: X-Axis Synchronous Belt Tensioner For Creality Ender-3/Ender3 Pro/Ender3 V2/CR-10/CR-10 V2/CR-10 V3/CR-20 Pro –Straighten And Stretch For Enhanced Performance by Patrick Carlson

The single sided X-axis didn’t fit at all.It’s a good idea, poorly engineered at least in relation to my CR-10V2. The distance from the bearing to the mount holes is too long. Much longer than the stock version and the adjustment isn’t long enough to allow you to move the mount out of the way. The mount hits the carriage long before the carriage reaches the end of the bed. You could reset your bed size in firmware and lose the volume but that’s just silly. No way to lock the adjustment either.seems like an oversight. I may cut it down and drill new holes at some point but the stock version works with less effort than modifying this poor design.The Y axis doesn’t fit either. Bed hits the mount before the nozzle reaches the edge of the bed. So, I cut the mount down and drilled another hole in it.made it work. A month later.we’ll, listen to the bearing. These units are poorly designed and built with junk parts. Buy something better.
