Ender 3 X-Axis Belt Tensioner Spacer
thingiverse
I started to notice some X-Axis issues so I took a dive into the subsystem. The first thing I checked was the belt tension. After adjusting several times I could not get the belt centered inside the 2020. No matter how I adjusted the tension and tightened screws, it would always veer off to the one side. But I found the solution! Here are a set of shims/spacers to move out the X-Axis tensioner so it is centered along the 2020 channel. What worked for me was 2.4mm. The following sizes are provided: -0.4mm -0.8mm -1.0mm -1.6mm -2.0mm Hope this helps!
