it’s been four days oops

More Assembly and Electronics!

6/28/2026

Ok, it’s z axis day! Gonna try to keep these recaps short since I’ve mostly been writing giant blobs of text with little images recently, since moving photos from my phone to the laptop and into the update log is a bit annoying, but yeah, z axis and motor mounts were started today!

6/29/2026

Realizing that time was really running out, along with the fact that NYC is attempting to reach high temperatures out of nowhere, a schedule was made and coreXY pulley stands were sent to print! First things first though, the z axis lift base thing was added , and some electronics stuff was started! It’s a little different from the wiring diagram, along with the fact we’re using a raspberry pi 4b, and a couple other stuff. Also, the docking bay got redesigned!

Anyways, coreXY stuff printed and the layer is assembled! The gantry has a bit of wobble (and the bearings aren’t a tight fit), but nothing some hot glue can’t help with! (Well, maybe the wobble). Anyways, mainsail flashed on the raspberry pi 4 and figured out the weird issues! Also, reminder to switch the jumper thing for input form the side to the usb power.. so, the t rods hit the gantry too, along with the fact that the build plate doesn’t exist. Decently productive day, 5 days left.

go go go

New month, and leectronics work continues! Sacrificed the aliexpress USB power cable, split the wires, and attached it to the LM2596, looks good! Also learned how to crimp today, so that’s pretty cool. There’s also a picture of the thermistor of the heater bed in the mainsail graph somewhere down there! Unfortuantely, I don’t have free JST connectors on ahdn, so we’re gonna be doing sketchy stuff with a dupont connector in there (the pitches are a bit different, yes, i know it’s crazy sketchy, shhhhh)

Anyways, after setting tool stuff to print, went downstairs and (thanks to my dad) got the t screws cut and a 15x15 build plate out of some aluminum (it’s like 1.3-1.6mm thick?). We did have to make it out of sheet aluminum that was laying around, but it came out alright, the holes are just a little misaligned but that’s a bit on me. Anyways, realized the tool stuff printed was super cursed, had to work on redesigning a lot of parts, specifically the sahft collar, the gearing (no more bearings should be needed, all the stuff should be using filament as deadaxles). Anyways, we have to fix this cad stuff (half way done), then hopefully belt the corexy and do electronics while it prints tomorrow (aka, today)?

Well, that’s it for now, gotta go fast (sonic reference?), only four days left…
