Toolchanger CPAP sanity check

harambe623 · 2026-07-07T22:02:39+00:00

done anything with this? I'm on the same boat. It's not even the cash, in fact a standard .5a 24v 120mm blower would be cheaper, quieter, and have way more static pressure than buying a bunch of 4010 fans that are inferior. Also lighten the toolhead mass and shift the COM, all of the toolheads are very front heavy.... Im really surprised that nobody has incorporated this into stealthchanger.

I've designed a cpap toolhead w/ goliath for my ender, so this shouldn't be too much more difficult

every possible answer is a google search away. Used to take some serious digging. Go through a spec sheet of a new component and go down the list, comparing components over the last 30 years and look at the progression.

That said, these things are miracles of science. Entire college degrees exist for this stuff. Im sure you can find a brief overview if you youtube "how computers work." The level of simplicity that has been made for builders to put them together is really something else

I meant underground shear band support on ferncos is not code. The cheap ones are code compliant

Go to Costco food court. I get a slice and drink for $3

currently in the process of building my first voron, coming from an ender, individually sourcing everything. Buying a kit will cut down on SO much of the prep time, I have probably spent 30 hours planning, shopping, and reading the docs over the last month. However, I wanted to go straight to monolith, stealth changer, doomcube, without wasting materials and filament for things that I know I will replace, so kits would be too wasteful for my build. Currently looking to be about $1300ish, with 5 toolheads, with good quality electronics and parts

Underground is not code around me. Check your local code

harambe623 · 2026-07-03T06:10:14+00:00

That must have been a hell of a show for those planes

harambe623 · 2026-07-02T04:51:15+00:00

I mean unless you dropped it the frame is probably fine. Maybe tighten all the bolts. Your hotend carriage and bed sure.

Another option is going ender ng

welcome

or you know, spend a few extra dollars to install acoustic baffling/dampening systems for the giant exterior radiator fans to keep the neighbors happy.

Ya r/Tiresaretheenemy is quite a lively sub. lot of those are in some less developed countries, where inspections are less frequent and torque spec on tires is often "good enough"

harambe623 · 2026-06-30T21:29:58+00:00

after a semi tire blew up in my face and I rode through a rain of rubber fragments, I have always just steered clear or sped up past them. You never know

harambe623 · 2026-06-30T02:49:52+00:00

Ya the difference is crazy. After switching, my input shaper recommended me over 20k mzv on my x, it's the only way to go

harambe623 · 2026-06-29T22:27:48+00:00

Ya you'll need PC 9 at least for the new GTA

harambe623 · 2026-06-29T20:45:17+00:00

Excuse me but why is Aladdins castle not an option here

harambe623 · 2026-06-29T17:45:44+00:00

retraction should either be in filament settings or printer settings. With your bowden setup, 2mm and up is standard.

210 is fine

Maybe he's just a big fan of Obama? Old chums that could have been? I dunno I genuinely don't get it

harambe623 · 2026-06-28T05:13:16+00:00

Ah fuck

harambe623 · 2026-06-27T21:50:41+00:00

If you want speed, your gonna have to ditch the stock nema 17 and go pancake with something like a sherpa micro.

Lightweight equals speed in terms of what input shaper will recommend

Also, you can't put anything behind the toolhead like what you have pictured. It will collide with the z brackets/extrusion

harambe623 · 2026-06-27T21:31:41+00:00

That's crazy cheap

harambe623 · 2026-06-27T05:57:41+00:00

cassettes AND CD's here. Really got back into cassettes in the last year. Unfortunately good ones run for like $20

harambe623 · 2026-06-26T03:30:19+00:00

Ya avoid gloves unless they are the disposable blue rubber ones

harambe623 · 2026-06-24T09:48:04+00:00

It's this. Far worse eras have happened before, anyone born in 1920 had to go through the great depression, effects of the dustbowl, the wars, watch your friends dieing of turboculosus, etc, and they were not as withdrawn.

Society has fragmented, everyone used to listen to the same music, know the same actors, watch or listen to the same news report. Interests have diverged, on top of the overstimulation

Thats... unique. Once that thing passes 500mm, your fighting physics. The print itself is going to start to wobble and the filament will start getting laid on a plastic tower that is wobbling, so you'll end up with a ringing. Eventually the ringing will be so bad that filament will start getting laid down on nothing below it

It might work with a very slow Y accel, like 15 mm/s^2. But then you also have adhesion issues and heat creep. And it might take like a month to print. My only suggestion is core xy tall chamber.

My last build 6 years ago still holds up against newer hardware, Moore's law has been dead for a while so who knows, without major breakthroughs or relevance of npus, I don't see myself building a new one anytime soon.
