I’ve been working on an Acme upgrade for the Prusa for a little while. Previously I threadmilled the nuts out of derlin. Today I turned down the 3/8 Acme rod on both ends. One end fits into the 608zz bearing in the MG lower end and the other fits into a coupler. Tomorrow I’ll be making a set of couplers to mount up to the motors. Venom is almost ready!
