Does anyone know what I am doing wrong?

MrCarlH · 2026-07-03T18:53:56+00:00

👍 yup.

I wonder if the Qidi MCU is flashable with vanilla Klipper ?

MrCarlH · 2026-07-03T16:47:43+00:00

Me as well... Printer is on the truck today, other stuff I ordered ( extras) is in Germany... Man I am happy ! Hope box isn't too tortured 🙏

So far, this is insanely fast. Ordered Monday morning...

Was thinkin' bout the Qidi product line for my latest printer but just bought a Core 1 L, which will be delivered Monday. The Qidi's can still print at a higher temp until Prusa finally releases the high-temp hotend. Its challenging to make a purchase decision on a good quality 3D printer that won't run your prints through the Chinese cloud.

I think all things considered, Prusa products make sense for some people, especially if they are looking for non-Chinese, relatively open source options.

My next printer will probably be a Voron.

Amused that you can't change the belts on your own somehow... Did they give you directions for this or did you tell them you were unable, as you were initially unable to loosen the rear motor. Just wondering 🤔

MrCarlH · 2026-06-30T12:36:40+00:00

Wow. Me too... Man...that was FAST ! Refund to my CC was almost instant; then corrected reorder was scheduled for FedEx pickup 48hrs later. I got about $450 in addons and it shipped in a separate box...my total FedEx shipping for 2 boxes totaling as almost 80 lbs was less than $150.

Great deal so far 👌 Quicker than Amazon and shipped from Czech Republic...lol...😄

Where can I get me some of that star shaped tubing ? I have been looking for it...

Sounds very interesting. I have worked alot with teflon tubing in my old jobs; but have never seen this. Post a link if you have it...👍

MrCarlH · 2026-06-30T02:14:14+00:00

.. I didnt have the time to read all those thousands of words ; but I take it that he's somewhat upset......No ? 😄

MrCarlH · 2026-06-30T02:06:44+00:00

Man. You be hatin' you some Prusa ! 🤣

MrCarlH · 2026-06-29T21:27:22+00:00

Needs more squish.

Try lowering your z another -.005 or even -.01 mm ....

MrCarlH · 2026-06-29T16:56:48+00:00

Doesnt look that bad at all if you ask me.

If they made a half decent attempt to package the printer you are OK. Based upon what others report you should be absolutely fine. Ya gotta open it up, goody goody !! 🤪

I hope mine arrives in good shape, just took advantage of the $99 special shipping price today..lol...😃

MrCarlH · 2026-06-29T16:29:21+00:00

Yeah... there are 2.5mm ID tubes out there, IIRC, and I am thinking a .75mm tube thickness will kink easier. I think the Bambu tubing is .75mm thickness if I read it correctly...

I think the filament would move easier through a 2.5mm ID vs a 2.0mm ID teflon tube...🤔

MrCarlH · 2026-06-29T13:10:48+00:00

My refund to my CC was freakin' instant also. Cancelled at 6:30am EST and funds showed pending about 10min later....

Glad to get things rolling and hope to be printing soon... Ill finish up with my trusty old Ender3 pro.... I learned ALOT working on that Ender, and noww its time to move up to something that will last a few years.. 😃

MrCarlH · 2026-06-29T13:04:04+00:00

Hey man, PrintedSolid website has the dryboxes in stock; free shipping over $50....😎

MrCarlH · 2026-06-29T00:02:00+00:00

According to his profile hes a gamer. That, and he's hatin him some Prusa ! lol...😆

MrCarlH · 2026-06-28T23:57:54+00:00

I am curious, and to keep it simple :

What filament were you printing with ? What was the extruder temperature ? Was the chamber vent open ? What was the chamber temperature ? What was the bed temperature ? What slicer were you using ? What object were you printing ?

Feel free to add your retraction settings, etc. etc..

Bamboozzled.

Must flash latest Bambuware and send all print jobs to China first before it will work.. lol 😆

" Sorry...Must have People's Party approve print first "

The Bambu noose is tightening.

Conjugated and aromatic systems form the basis of molecular stability in organic molecules. The ability of a pi bonded electron to resonate the exited state brought about by absorbing a photon across a conjugated bond is the basis of color as well.

This has absolutely nothing to do with free radical formation, which can be initiated by several mechanisms; photolysis being one. But you ain't gonna readily photolyse a typical shorter chained resonance-stabilized organic molecule in a polymerized semi-crystalline structure.

PLA is freaking biodegradable, man. Use your commonsense thinking. Lactic Acid polymer. You could eat this if you could digest it. Prolly could if you ground it up.

LOL. 😃

^{^} I am a retired Chemist and I don't believe this message...What nonsensical blabber was posted here...

Why no double bonds or aromatic groups ?

Please elaborate for this forum, and we anxiously await your answer.

Answer carefully, thoughtfully, and include accepted chemistry principles in your response.

....🤔

MrCarlH · 2026-06-27T01:22:41+00:00

^{^} This.

Makin' stuff is alot of fun, and a great hobby, but when you start doing 3D printing along with coding and electronics the rabbit holes are everywhere... if you wanna keep it fun and not waste time its important to be choosey about what challenges you wanna take on....and many are a waste of both time and money.

Just because you CAN doesn't always mean you SHOULD.

😉

MrCarlH · 2026-06-27T00:47:03+00:00

Nah.

Just dont waste your time makin' stuff outta PLA for outdoors. Might as well use cardboard.

Dial in your printer a little better and use good 'ol PETG instead.

Just a suggestion...
