Overview

The goal was to make a fast printer. Currently printing quite comfortably at 200mm/s with 3000mm/s² acceleration. (The benchy in the pic took 20 minutes)

The design does include oldham coupling but from what I've seen they aren't necessary unless your lead screws are not straight.

Base

Mount on a 850mm x 610mm piece of MDF or melamine.

The X endstop is designed to clasp a SS-5GL part. The usual ones may fit, but this is the preferred part.

I'm using an MKS base with TL Smoothers and Klipper firmware.
