Here we go! THIS is #Ingentilire It’s my attempt at a 3.0 printer (being the third one I’ve built) and it’s got lots of little details that don’t come through. Case in point: The frame is held together using button head screws, as are the bearing supports. Why? Because they’re clean, can be installed blind, are cheaply available, and rely on the cuts of the extrusions to provide perpendicularity. Order them cut to length and tapped from Misumi and it helps an end user without heavy tooling build a rigid and square printer.
It reuses a lot of identical printed parts. Why? Because once you get one part dialed in (e.g. bearing supports), you make 7 more just like it. Why are X and Y axes seperate? Because they let you play with any size carriage you want, plus it’s easier to set a datum in one corner, get the carriage moving smoothly, then set the bed equidistant from the carriage.
Like I said…lots of thought for lots of reasons. Looks like it turned out okay. (Github location to come shortly)
