Iterating on my single belt x/y design from last year.

Added a “real” Z axis (which has eliminated the wobble from my terrible “I’ll just use an old flatbed scanner chassis for Z” concept), and upgraded to an E3D Volcano.

This will never be a super precise machine - it’s for making big bulk parts fast.

Regardless, I did print out a 4:1 gearbox with it at 0.5 mm layer height and it actually fit together and turned. So, it’s not terrible.

I think with some more iteration, it could be converted into a flat-packable briefcase printer. (Add hinges and latches to the Z platform and the x/y cantilever, and I’d be halfway there)

Assembled 3D printers are expensive to ship right now because they are big boxes of mostly air. Being able to flat-pack a printer, and have a 60-second fold-out-and-print time would be excellent for educational purposes, using in a tiny house, bulk shipping, etc)

I like the foldable aspect you are tackling here. :slight_smile:

Repetier’s G32 bed leveling and a glass plate are all I need to get an accurate level every time.

Did some precision calibration checks - looks like the total moment of the X arm is about 2mm (due to slop in the Y sled’s bearings). To mitigate this, looks like I’ll need to separate the Y sleds’s bearings substantially.

Alternatively, I have some ideas about using 3 flanged bearings with a tension adjustment bolt on the middle one that may accomplish the same results
