RepRap: Blog

Slight change to the Z tower to get rid of the spacers needed when mounting large NEMA17 motors on the Z Axis Driver. This also allows the Z Motor Pillar Assembly to be bolted to the Z Tower as well as the Z Axis Driver, leading to a more rigid structure. Moving the Z Axis at high accelerations has been shown to make it wobble a bit, and this should help. The updates have been uploaded to Github and Printables V0.04 repositories.

I've also spent a bit of time getting the Prusa XL running. While it prints multiple materials, that trick won't be needed to build μRepRaps as it would limit people's ability to reproduce the project However, the μRepRap itself is intended to be a multi-material printer, so the XL will provide an opportunity to develop the techniques for multiple material prints and create macro-scale models for demonstration purposes.
