Mr BI have one 3D printer that is actually working, one that I'm waiting on a pair of new linear rods for, two that I'm making custom beds for, and three (!) that are total rebuilds in progress. So, I would have seven printers, each one different from the others. Ugh, mistakes were made.
While yes, I enjoy building and modding the printers themselves, this is a bit much. If I get all seven working they'd be too inconsistent to form a print farm.
