I’ve upgraded my Ender-5 pro with three of these belt tensioners and I’m wondering if it’s really turning out to be an upgrade
Installation was easy and they do make adjusting the belt tension easier … but as you notice in the picture below the original bearing did not have any teeth whereas the upgrade does. The stock bearings allow the belt to slip ( by design ) and insure a consistent tension along the length of the belt
The thing that is bothering me is that the Y-axis & X-axis stepper assemblies also have bearings with teeth and having teeth on both ends seems to introduce in imbalance in the the tension as shown below: the red side of the belt having an unbalanced tension with the green side due to the teeth on both ends gripping the belt.
So, am I overthinking this, or am I introducing a potential ‘belt-backlash’ problem by using these ‘upgraded’ tensioners?
