Tronxy x5s single Z motor conversion

thingiverse

This is my attempt to convert the Tronxy x5s to single Z motor drive. Parts needed (to purchase) : - 2 GT2 40T pulleys, 8mm bore (one for each threaded rod) - 1 GT2 20T pulley, 5mm bore (for motor) - 1 1220mm closed GT2 belt - 2 Threaded rods, 8mm x 500mm long. I think the original ones are too short for this mod. Need to check that out. Parts to pick from your existing printer : - 2 KFL08 bearing flange (the ones that are on top of the threaded rods) - One of the Z motors. Since the motor pulley is smaller than the rods pulleys, you'll have to change the steps/mm in your firmware. No need to increase the stepper current, since there's a 2:1 ratio on the belt side. Edit : I finally received my new Z rods, so I could test this thing ! https://www.youtube.com/watch?v=w7fYIKnkMqk It works great, no more bed tilting ! ##### Edit : V2 added ! Make the supports higher, so a 500mm leadscrew will fit for sure (don't rely on stock 430mm, they are too short !) Make the motor support longer, since 1220mm belt are fitting very tightly Added "anti wobble" Z support for leadscrew nut . Two options : - Use standard M8 (or 5/16") threaded rod + nuts - Use 8mm leadscrews + nuts I've not yet tested the threaded rod version, but it can be cheaper and easier to source than leadscrew... Next version to come : with idler pulleys
