Finally got my Prusa operational again so I can print the remaining Tantillus parts. As the final printed parts roll off the line, I'm anxious to get started assembling, but I'm wondering if I can roll with what I have, or if I need some more minerals.
In particular, do I need the "real" linear bearings inside the carriage or can I get away with printed ones?
Secondly, the drill rod I have for the axis is not polished and is kind of funky, should I leave this be or clean it up with something like scotchbrite, etc.
Also must 8 mm rod be used in the crossbars or can I use the same drill rod used for the gear-driven rods (especially if I use printed bearings)?
I think that's all for now. I'm anxious to get things together so I have an operational printer and can safely overhaul my prusa without risk of being printer-less
