TronXY X1 2040 Z-axis Linear Rail Carriage

I got pretty tired of the x-axis wobble from the misaligned delrin wheels on the z-axis, combined with the slightly smaller v-slots of the 2040 extrusion.

And even with the tightener modifications, there's still room for wiggle because of the wheels.

So to make it as solid as possible, I opted for installing a MGN-12 linear rail to support the x-axis arm.

Now it doesn't budge.
