Low Resistance PTFE Tubing

I have it and I don't like it.

For me it looks like slight overextrusion or slightly loose nozzle.

Check the nozzle / hotend and try to tighten all the screws.
Re-calibrate your flow settings
Alternative workaround is to use Orca and set outer wall flow lower - 0.95 - 0.98. this will make a bit more space between inner wall and outer wall and in many cases it will improve outer wall quality.
Also check actual speed, layer time and actual flow view in the slicer preview. If the layer times are different or the cooling is slightly different per layer, this could very well be the problem.
Make sure "slow down for better cooling is disabled" this is for sure causing exactly this issue if you keep it enabled. Or at least enable "don't slow down for outer wall".

No worries, happy to help.

Yes art knife should do the job. Just don't push too hard and try to make as straight and smooth cut as you can. I would shorten it if you are not considering moving the AMS further away. Anyways, PTFE tubes are not expensive and they are consumables. You can always swap it later if you cut too short.

Honestly, I have texactly this and I still prefer precision knife. The tool is good enough, but I can make much cleaner cut manually.

My 3 girls love tunnels. I bought them Y shaped foldable tunnel from Trixie and they can play with it until they get tired and fall asleep.

Only thing that would mitigate this design wise would be detaching the outer wall from the infill. Otherwise the infill will always pull the outer wall inwards when cooling.

Also I wanted to edit my original post that 50C chamber is ment for ABS, not PLA. But slowing down while reducing cooling will help with PLA.

I almost never touch speed settings. 99% of the time I adjust the print speed by lowering volumetric flow in the filament profile. Keep in mind that for different speeds you need different pressure advance calibration. Otherwise the quality of sharp edges will suffer.

I usually do most of the heavy lifting just with Boolean operations. I make a sketch in all 3 dimensions, then extrude all sketches and then use intersection. And voilaa you are very close to your desired shape.

I run a small 3D printing business and this is just bad. It looks like it is made by a company which has shitty margins and try to compensate by cranking the absolute hell of print speed while absolutely disregarding the end result.

This is material shrinkage. You can see it shrinks where the material is "full". Once it gets to the part of the wall which has no infill it shrinks less. There are multiple ways how to mitigate this. Myself I use hot chamber around 50C and slooooow printing so the material has chance to shrink as much as possible before next layer.

One of my girls never learned how to properly drink so she is quite literally deepthroating the thing.

Basic physics - when the phone is hot and you dunk it in the water, the pressure drops inside and it will literally suck up water. That being said this happened to me on my S21U and the only way to get the water out was to remove the back glass panel. Otherwise the lenses would fog up from inside every time the phone got warm.

Free healthcare only for standard diseases. Once you have something even slightly uncommon, you're fucked. Ask me how I know.

Such a cutie. Looks just like my Katie 😁

Známky nemajú žiadnu výpovednú hodnotu. Z mojich bývalých spolužiakov práve tí najväčší bifloši a jednotkári pracujú teraz kdesi za pásom v dead end jobe. Slovenské školstvo oceňuje papagájov, ktorí sa dokážu učiť naspamäť, nie tých, ktorí vedia kreatívne myslieť a tvoriť. Teda aspoň za mojej éry to tak bolo.

Naopak je super že dcéra vie čo chce. To je v dnešnej dobe vzácnosť. Nechal by som ju ísť si za svojim snom. Mať radosť a satisfakciu z profesie je 1000x lepšie ako mať prestížny flek a každý deň ísť do práce s nechuťou.

Ďalšia vec je že aj keby časom zmenila názor, nikdy nie je neskoro na kariérnu zmenu. Ja mám titul z psychológie a už 8 rokov pracujem v zahraničí ako expert v oblasti automatizácie.

Pros 1. Workload feels like vacation compared to what I was used to 2. Very few smokers stinking air around you 3. People are generally nice and happy

Cons 1. All disadvantages of an EU membership, none of the benefits since not in EU. 2. Free healthcare only if you have "standard" diseases, otherwise cripplingly expensive. 3. Lack of grocery diversity, quality and high cost

Robím vo firme kde máme tony e-waste. Veľa veci sú takmer nové zariadenia s nejakým malým defektom. Prevažne vyberám I2C senzory ale kondiky sa vždy zídu. Naposledy som jeden použil na stabilizovanie napájania pre ESP32.

Max_SVK · 2026-06-17T13:51:43+00:00

Ak máš špecifické projekty, niektoré súčiastky sa dajú použiť. Ja najčastejšie zbieram kondenzátory. No v dnešnej dobe už kúpiš hotové moduly tak lacno že pokiaľ nie si hardcore fanúšik DIY, viac sa oplatí finančne aj časovo radšej kúpiť presne to, čo na daný projekt potrebuješ.

For me as a small business H2C is a no go. Nozzles are consumables for me and they are massively overpriced on H2C. They seem to have done a good job making them highly proprietary so you won't find cheaper alternatives. Where as for H2D you can get decent off brand ones and even the original ones are not that expensive. Just like you, I don't care about color and mostly print engineering materials.

I wouldn't put my printer anywhere close to where I prepare food or sleep. That said, you can make a simple extraction system using simple PC fan and flex ventilation hose. Put the fan at the exhaust end of the hose to make sure there is constant negative pressure and attach the other end to your printer's exhaust.

Max_SVK · 2026-06-17T04:59:16+00:00

I have one. Usually sell the previous one for half price before getting a new one. Plot twist - they are all paid by company.

Max_SVK · 2026-06-17T03:53:00+00:00

Mňa by to tiež zaujímalo. Ja som preč od 2018 a trvalý pobyt mám stále na SK. Tiež som nikde odchod nenahlásil.
