As mentioned in the March 22, 2021 Kickstarter Update... any news when the kit will be available? I guess I could just follow the STL files, but wouldn't mind the having the kit direct from Makertech3D. I am going to try a drop-in ball bearing to see if that helps my z-banding any. Wish I could get back to the perfect NO z-banding like I had there for a little while. Our printer collection has expanded quite a bit since last year when with the Axis and Prusa only. Have a Prusa Mini up and running. JG Maker IDEX and a Weedo X40 IDEX also up and running. In process of building a Rat Rig v-Core 3 500mm Core-XY, and as soon as that is done, have a SecKit Tank in the box to build (checked the Linear Rails as request, but otherwise still sealed up) Working on the Linear Rails right now for the RR500 which is what reminded me of the Axis Linear Rail upgrade. I'll post some pictures of our new farm setup - we're totally addicted.
