The V4 / (Repeat v2) is still a work in progress and we need to help with the documentation.

The forum thread has about as much information as is available
I’ve got the printed parts all printed, and have the electronics but still need to gather 2020 parts, linear rails, and more than anything decide on a heated bed.
The heated bed is actually the part that is stopping me at the moment as there isn’t a reference design with a specific “go buy these parts” available for the V4- and I don’t have time to finish learning Fusion360 to do it all myself. (Though, if I do that, I’m going to use one of my spare TAZ beds and modify it for 3-point mounting.)
