TronXY X5/X5S Cart upgrade

thingiverse

This replacement, along with other modifications I suggest, will significantly reduce layer shifting and prevent motors from working harder than necessary so replace your carts on the TronXY X5S with these new ones. The X5S_Cart-1.stl requires two 6mm aluminum spacers and two 6mm eccentric nuts to function properly. In contrast, X5S_Cart.stl only needs the two 6mm eccentric nuts. After you make this modification, you will notice a significant improvement in how smooth the R and L are, and I mean extremely smooth. To take it even further, remove the extruder plate and drill out the bottom wheel hole (of the three holes) with a 9/32 inch bit (5/16 will also work). Then, place an eccentric nut there as well. Due to the thinness of the extruder plate, you may need to remove about .1-.2mm from the eccentric so it fits flush; this took me less than a minute using a metal file. My entire system is much better since I added the five eccentrics in total, and you will be amazed too. One other thing worth noting is that the 625zz bearings on all wheels were extremely poor on my machine, so I replaced them with 625RS (from AliExpress for less than 12 USD delivered for 50) and this made a huge difference as well.
