9/20/2026 - 11th Update!

missed one day, but miss two? i dont think so. anyways, dramatic opening aside, it is 11:25 PM, just celebrated cake day (a couple days late but still great :D), so yeah, in celebration of becoming yet another year older (my foot hurts), time to get cadding! (brb)

ok, it’s 11:50 PM, might need to lock in, in other news, doggie just got 97% (again) and 91% on grief tonight! might want to tune in (if youre reading this from the future, today’s stream 390)

anyways, first things first, we need to find a stepper motor ideally with lead screws built in (those exist?) (yeah, apparently so)

ok, it’s 11:58 PM, gonna go watch a movie, brb!

ok ive returned at 1:30 AM to focus on two things at once (i gotta get the sticker streak continuing), so yeah

ok now what are the heights of mgn7c rails…

why does no one have cad models for mgn7c rails that arent filled with other stuff…

ok 1:46 AM and now im actually gonna be fully focused

so, this might not be the most ideal setup. currently the motors really far in the back, however, theres no real mounting solution going on here, so here’s the dilemma. the motors too big. like. too big. additionally, this means that it kinda pokes through the back, or in a weird way. anyway this happens isnt very good, since the gearing has to go through the extrusion. obviously, we can do a hex adapter and do a spark here, but that’s not a good idea for obvious reasons (re: spark)

do we actually have to look into pancake motors? yeah, i think we do…

also, one more thing, it might be a good idea to split the belts to be on both sides instead of just one, just to balance things out a bit

got a little distracted with compact hotends, but yeah, went down a rabbit hole, we need ptfe tubes (spark did not have these), wow, theres a lot to do

turns out, sourcing these things is super annoying! looked for nema 11s with integrated lead screws, all of them are mad expensive, probably just gonna use a shaft coupler, yep certainly am.

anyways, lets do some math, the 45mm motors have (allegedly) 10Ncm of torque, should be enough with a T8 screw and having two of them (additionally, to help with lower layers, an idea that came across the other day was adding springs at the bottom)

uh idt this is gonna reach the full range…

anyways, it’s 2:43 AM, mostly a bunch of research and small adjustments, nothing too big today, hopefully more stuff tomorrow?

that said, it’s 2:44 AM, good night!
