TronXY X1 2040 Z-axis Linear Rail Carriage

thingiverse

I was getting fed up with the x-axis oscillation caused by the delrin wheels on the z-axis being out of alignment, and the slightly narrower v-slots of the 2040 extrusion weren't helping. Even with the tightened modifications, there's still a bit of play due to the wheels. So I decided to install an MGN-12 linear rail under the x-axis arm to keep it rock-solid. It no longer moves an inch.
