Now sad news from my side, an old 2014 kickstarter 3d printer popped out from my basement:
https://www.kickstarter.com/projects/1784037324/bi-v20-a-self-replicating-high-precision-3d-printe sell it and get a new one? Or better to follow the rabbit hole trying to get it up and running?
I am sad because I feel like it is a cheap, low quality big 3d printer. WASTED. My spider senses are telling me to not touch this thing and let it go on Ebay. Yes, I am so stupid I bought it in 2014 and left in the basement until now.
I would strip it out for spare parts for a more civilised unit. My experience with a couple similar units at the local Hackspace taught me that
Kessels without metal framework connectors are a complete charlie-foxtrot to get set up square, and no matter how much people who have them argue otherwise, they NEVER keep that setup; you're CONSTANTLY having to re-level/resquare the fucking thing.

Worse, they will drift appreciably DURING A PRINT.

That, combined with exponentially lower (literally a factor of 10) maximum layer resolution makes even the best belt-drive Kessel good for VERY ROUGH modeling of larger pieces, but just

for pretty much everything else. You wanna cheap printer to make gun stocks with? Kessel is a good choice, IF you can keep layer adhesion going at those heights. (A whole 'nuther level of frustration; trust me.)

That unit looks like it uses a regular RAMPS/MKS Base 1.2-1.4 controller and NEMA 17 steppers. These are used in pretty much ALL the PRUSA-i3 descendant Cartesian printers. Definitely good parts for another printer, especially if you have the later 1.4 with socketed stepper drivers.
