Print Apnea No More! Custom Voron 2.4 CPAP Cooling

[@Dead_Aim556]

Just want compliment you on your level of professionalism and polish on these videos! You have better videos than most people who have millions of followers and decades worth of content! Keep up the great work as you got something special here

[@Browzzrr]

thanks for the support!

[@unknown_user2345]

Feel absolutly amazing to see my parts printed and working! Also, I really like the colors! Best regards, Sascha/ Flaigenstool Engineering

[@Browzzrr]

Great work, thanks again!

[@WarriorServent009]

Really great stuff! I look forward to your next video!!

[@oldguymeltsplastic]

Another fantastic video! Thanks for sharing the before and after footage!

[@jimwhite4482]

´can't wait for the Micon Stuff because of your quality videos! - Please keep going !

[@Browzzrr]

First Micron Video should be up tomorrow!

[@jimwhite4482]

​@@Browzzrr I am a bit unsure where to start - with Micron or 2.4 I like the Micron because of optics & mods & tiny - But to be more rational i might go with 2.4 (first).... argh :)

[@Browzzrr]

@@jimwhite4482 if you have never built a printer before, the trident is the easiest! if you really want the flying gantry, the 2.4 is also excellent, just a bit more challenging

[@jimwhite4482]

@@Browzzrr I assembled an Anet A8 approx 7 Years ago and modded with alu profile case due to the lack of stock stiffnes etc. It is still working btw. I am familiar with raspberry pi, arduino, electronic and tinkering things. 2 Months ago i bought the Creality K1 and now i want to get back in. I guess it is only a matter of time that i own more then just one Voron. I am just struggeling where to start with ; for now i want them all :)

[@Browzzrr]

@@jimwhite4482 I have the same problem! 2.4 or Trident is your best starting point.

[@TimothyScotts1]

Thanks for the awesome video man! I am just about to start the conversion on my 250 Trident and cant wait to see what it can do :) Also, I can wait to see how you go with the Micron180+! I bought the Formbot kit and its seriously my favorite printer so far! Its the perfect size for me and I reckon it could be modified to do some pretty crazy speeds :) Keep up the fantastic work!

[@Raytenecks]

I had been considering a mod like this, and the results are amazing... But I don't think it's worth the extra noise for me. Hopefully I can find another cooling solution that does the job but isn't as noisy. I keep thinking about the dragonburner, but it's ugly and apparently doesn't support Tap.

[@Browzzrr]

Yeah the noise is a hefty trade-off. I am chasing performance, so it is what it is, thanks for stopping by!

[@kazolar]

you don't run CPAP at 100% -- like ever, my PLA configs have 40-60%, it's far less noisy. Also using an analog control board, you get a lot more accurate control of the CPAP air than doing the fake PWM signal from the pi.

[@Browzzrr]

@@kazolar I run my cpap at 45% for regular printing, but it ramps up for overhangs. so it hits 90% a non 0 amount of time I also run it off of the octopus and not the RPI, not sure how an endstop pin varies. even at 45%, with the muffler, its louder than a combination of 5015's, so noise is still very much a factor for people who want a quiet machine.

[@perfectscotty]

Awesome video.

[@printsomething5093]

Thanks for the sounds comparison, you have made up my mind to not go cpap. The results aren't good enough for me to justify the noise, but this is for me, i don't want a loud printer.

[@mauxx91]

Where can I find the super cool model with voron logo you have on the back plate? Thanks great video!

[@Milkex]

bro. sick forearms. sick video.

[@Browzzrr]

thanks man! a lot of hard work and a lot of hard work went into the making of both :P

[@austinh_eth]

Tried to print the front plate and hose connector and noticed the holes were modeled to be 2.5mm for a 3mm screw. I noticed someone remixed the 2 pieces as they were also having issues, going to attempt to print that next but something to keep an eye out if anyone tries to print this

[@mrvicco]

can you post the link for your rear chain cable management?

[@stevehanwright481]

Thanks very helpful

[@watashimaiku]

Thank you, just installed one myself. I do have a question: My fan goes into beserk-mode when starting up until Klipper is started up completely. Is this normal? My setup in klipper is the same as yours.

[@Browzzrr]

100% normal, berserk mode is how I would describe

[@donald1792]

nice!

[@3Dgifts]

Nice build, really neat. Question, is the cpap basically a PWM blower fan?

[@Mulch4321]

Me when my 3D modeling device creates a disorder that causes my breathing to repeatedly stop and start when I'm asleep: Print Apnea Is this anything

[@radiotbo4646]

great, but mamooth maffler is way superior, give it a try !! :)

Hi mate, what filament did you use for your printed parts?

[@Browzzrr]

Polymaker ASA!

[@stevehanwright481]

@@Browzzrr nice colors, can spot its yours for a mile away.. once again thanks for the video.

[@stay_in_adventure]

I might have missed it in the video but what filament were you benchmarking with?

[@Browzzrr]

Sunlu PLA Meta!

you say you added or subtracted wait

I don't quite follow?

Formbot!

FROM CRAP TO CPAP

[@therick0996]

CPAP did less of an improvement than I thought it would

[@Browzzrr]

the 80+% overhangs went from garbage to very passable, I'm pleased with the results! the upcoming performance upgrades may also utilize it more so than the old single 5015

[@AndroidA258]

i think mammoth is a bit better

[@Browzzrr]

Mammoth is three times the size. Plus most of the noise comes from the air coming out at the hotend. A bigger muffler wouldn't do anything.

[@AndroidA258]

​@@Browzzrr you use spool behind, mammoth has the same depth as a roll on the back

[@Browzzrr]

It's bulky and wouldn't change the noise levels at the toolhead, I'm happy with the one I have

[@pista01slk]

I find that 100% CPAP cooling is too much. I rarely go above 50%. It's just so much better than a toolhead mounted fan.

[@Browzzrr]

Yeah I run 90% on heavy PLA overhangs Usually 20-50% for anything else
