Convert Ender 3 S1 to COREXZ kinematics (deprecated)

There is a new version of the Ender 3 S1 Corexz, version 2.1 → https://www.printables.com/model/492543-ender-3-s1-corexz-v21

---

I was not happy with the Ender 3 S1 z-axis layer line consistency, print speeds and quality. Dual z-axis uses 2 stepper motors + 2 lead screws and yet I was seeing print defects.

The corexz (with klipper) has improved speed and quality tremendously. My standard print speed now is 200mm/s (100mm/s external perimeters) yields really good quality. It can potentially print faster, but I don't require higher speeds and i'm afraid the printer might jump off my desk.

My apologies for the lack of documentation as this is a hobby and takes a lot of time / learning from my side.

I have to say it was totally worth the upgrade and I am not going back to lead-screw z-axis setup.

I have taken inspiration from Voron Switchwire and other corexz printer conversions. However, I modeled everything from scratch to be a cheap way to convert the Ender 3 S1 to corexz.

I would rate the conversion intermediate to advance as I am not giving instructions. It requires M3 / M4 / M5 bolts, nuts, t-slot nuts, brass inserts, bearings, pulley's, GT2 belts etc.

• Added motor mounts (lower x-axis) that allow x-axis to move down lower, I needed this as I added an MGN9 linear rail to the x-axis.
