I made the X Axis modification/upgrade by installing a linear rail MGN12 on my K1 max.
The gliders I downloaded from cults3d, a design made by “lashigt”, and made some adjustments on them by making the holes for the teethed gears little bit larger to 4mm diameter so I could use m4 bolts for the Idler gear 20T 5mm.
The printing results are great (Less till no VFA anymore on your prints) and a big improvement of the K1 max without having to root the machine.
