looks good. congrats on getting this to work.

how well does it maintain print calibration when you fold it move it and set it back up to print?

Sounds like is coming along. Pretty good for a first print. The bridge came out good.
While the corner cubes sound like they'd help, It's been proven they reduce rigidity over connecting the extrusions directly to each other, but rather add extra parts (however insignificant). Connecting them directly like this would be more rigid Dentist's Post on connecting Extrusion. and require less parts and cost less.
Quote
I'm sure you're aware either situation will require really precise cutting of the extrusion.
Quote
Which is why it's recommended to cut and then mill the ends square. Non square cuts will make it go out of square. I know you were using an Angle Grinder at the end and it's probably fairly difficult to get square cuts, and looks unsafe.
Quote
Not having a Mill myself, or a Chop Saw and not wanting to blow the budget buying either, I'd get a Miter Box like this one here and screw it to a workbench. I'd use a couple of Clamps to hold down the extrusion against one of the rails and cut it with a Hacksaw. Lastly check with a Carpenter's Square like this one here and file it.
Quote
I'd make every attempt to make those cuts square cause depending on how out of square the extrusion end cuts are, you may end up with portions that don't touch the corner cube or the other extrusion (if going without corner cubes)

Looking forward to more progress

That's looking from the top down when it's in deployed setup?

What kind of nozzle are you using?
Quote
28mm3/s is something that only a Volcano should be capable of melting. Usual nozzles have around 10mm long melt chamber
.Quote
And 3mm is not really efficient at high volume melting because it has a lot bigger cross section than 1.75mm (filament needs to be melted right to the center)
Quote
I am not sure about the size of those prints but 350mm/s is something that requires a long distance to reach unless you are using a very high acceleration. I doubt that you are really reaching that speed anywhere on the prints. Oh and even Marlin has a maximum speed of 300mm/s set for X-Y so I hope that is changed.

Looks like you have got a so called Z-banding issue. It is caused by an M8 threaded rod that is not straight. Pitch on M8 rod is 1.25mm and it looks like the repeating banding happens at this distance which proves it all.
