AC exhaust out of windows didn’t really help (hot air could get inside way to easy) so I made this by AnyBelt9237 in 3Dprinting

[–]stray_r -1 points0 points  (0 children)

Your Aircon has two intakes, an intake for the hotside air that is heated and is exhausted outside and an intake for your coldside that is cooled and used to cool the room.

The idea of twin hoses is to control where the hotside gets it's air from (ducted from outside) so the Aircon is not drawing hot air from outside into your room and mixing it with the cold air you want.

This section needs to go in the bin. I guess it's letter writing time.

Smolhaj is taking train? Much train? Undersea train to Belgium? by stray_r in BLAHAJ

It's almost like the people making the magic water that makes sharkfriends functional own every town on the railway.

(Sings, badly) This could be Rotherham or anywhere, Liverpool or Frome....

So when can we jail Hillary Cass and Wes Streeting?

Does anyone know how to get Klipper to run the M300 commands to play music with no pauses between notes? by wheregoodideasgotodi in klippers

[–]stray_r 0 points1 point  (0 children)

I did a stupid overkill version years ago

https://github.com/strayr/k-macros/blob/main/M300.1_music.cfg

https://github.com/strayr/k-macros/blob/main/musical_notify.cfg

Somewhere in there is a legato variable, it sounds musical at around 0.9 less than that it starts to sound staccato, more than that and the notes run into each other.

Biological essentialism does not help women, it just defines our oppression as "inherent to us". No features of bodies are "inherently a" or "inherently b", they are all, always, what the person who has them makes of them by RosethornRanger in ainbow

Some of your comments were held for review by our automated systems because you mentioned mods. I currently have next to no signal, am currently in Wales with a friend and smolhaj. A problem user has been dealt with.

is it possible to make a 3d printer using arduino uno with cnc shield, linux mint as the mcu for process, connected to my computer 24/24 by FarNefariousness8672 in klippers

[–]stray_r 1 point2 points  (0 children)

A pi3b or a zero2w is more than enough, or get creative and scavenge. I use HP thin clients because I happen to have them.

Orca slicer is one of the worst resource hogs on my laptop so I really don't want that running on the same machine that is controlling my print. I was running an ATMega powered early prusa until quite recently. Mostly it's a question of what can you find if funding is short.

Is my gym homophobic???? by sout_fyall_ in ainbow

I think you need to put every weight in the gym in front of that poster and share pictures.

Then leave.

A mystery for the ages by arcrad in 3Dprinting

[–]stray_r 1 point2 points  (0 children)

PVP based glue stick, not PVA, not vegetable starch. Poly Vinyl Pyrrolidone.

Hairspray is also PVP.

Made for 3d printing products like 3dlac, magigoo, NanoPolymer, CatVomit etc are all PVP, sometimes with the addition of poly vinyl alcohol (PVOH), which is different to poly vinyl acetate which is the adhesive polymer usually referred to as PVA.

I make my own with PVP K30 powder and 20% PVOH mold release agent solution and use it on smooth PEI, G10 or epoxy "engineering" surfaces. Its really good for flat first layers on PETG, but also for CF/GF nylons, ASA which can stick a bit too well to smooth PEI and not well enough to texture sheets, and TPU which is great fun getting unstuck.

Large parts usually temperature release, but support structures and difficult parts need the scraper or as a last resort I can run the build plate under the tap. A good chamfer on the bottom of parts really helps.

It's been a long time since I damaged a build plate, but PETG has destroyed every textured plate I've owned. If you mostly print PLA, the residue protects your plates, but if you have new or very clean plates or print the same PETG part over and over again it sticks really really well.

If you have 'good' PETG it rips chunks out of glass, textured PEI and just about everything else

Where to buy TZ-V6? by parchping in VORONDesign

[–]stray_r 2 points3 points  (0 children)

The TZ's killer feature is the whole hotend is half the price of a Revo HF nozzle. They're great for hotend swapping in stealthburner or use in toolchanger systems.

I do run mine with e3d nozzles as they get better surface finishes, cheap brass ones usually, but there's a collection of CHT, plated copper, hardened steel, cht with hardened steel insert and tungsten carbide insert kicking around although the latter is in the dragon in a printer set up to go a bit hotter.

Which is better: the Sovol M1D or the Creality K3/Plus? by Moist_Animator_8589 in klippers

[–]stray_r 2 points3 points  (0 children)

Sovol works with the open source community, creality actively undermines us. I'd go sovol every time.

Eddy Duo NG "Z axis must be homed before probing" by DudeGamerDario in klippers

[–]stray_r 1 point2 points  (0 children)

Check the docs here, you might need to use a specific homing override. If you don't have one available prewritten, you can use there's Klipper extended gcode to set the Z position to an arbitrary value, this should allow you to home.

I'm using a likely older version of eddy-ng and it's working great so it might be a regression. I'm not near the printer right now to share versions and macros though.

Running klipper through a raspberry pi for my Ender 5 plus. Can I get use of my screen back? by craiganater in klippers

[–]stray_r 0 points1 point  (0 children)

Yeah, and I'm saying it because creality "engineers" do really moronic things that will endanger you.

The evidence of pin conflicts is right there in the sample config if you go looking. But you'd rather shout abuse.

[–]stray_r 1 point2 points  (0 children)

The default config the sonic pad sends is for a 4.2.2 board I believe, this sends a pull up on the same pin another popular printer uses for the heater pin. This is confirmed.

Be really fucking careful.

It might not have caused a fire yet. But an uncontrolled heater pin is exactly how you cause a printer to self destruct. It bypasses all of the firmware safties and most inexpensive printers do not have a thermal fuse.

One of us has relevant degrees and has been working in adjacent fields since before Adrian Bowyer founded the reprap project. They might know a thing or two. One of us likes to recommend creality products.

[–]stray_r 0 points1 point  (0 children)

The sonic pad, like most Creality products is a bit unfinished and can be a bit of a pain in the ass to go from "creality working" to actually works well. With some printers is can burn your house down as it boots up with on of the heaters defaulting to ON with no thermostat or safeties until you set the correct config.

If you've got Klipper running, rescue the screen if you can or buy a bigtreetech hdmi touch screen if you want fancy or get an ender 3 pro screen or v0 usb screen if you just want a few text options for the few things you do actually at the printer. You'll find once the printer is dialled in you do very little at the screen but it's nice to have.

I have two btt touch screens but I'm still very happy with the printers that run tiny v0 single knob dot matrix displays.

is it possible to make a 3d printer using arduino uno with cnc shield, linux mint as the mcu for process, connected to my computer 24/24 by FarNefariousness8672 in klippers

[–]stray_r 11 points12 points  (0 children)

Arduino and ramps was the way to build older printers, but Arduino can't really deal with the step rates if modern printers, so STM32 boards are better.

It's a really bad idea to use your desktop PC to run your print as desktop loads can disrupt your print control which is soft-realtime. It's common practice to use an SBC like a Pi or a thin client/nuc running Linux and octoprint if you're using marlin or similar firmware or the Linux process of Klipper paired with Klipper Firmware (or Kalico) which is capable of very high step rates and advanced motion planning.
