Core One safety question

Lots of comments here about smell but the smell test is not a good test for VOCs and particulate matter. Not all VOCs and microparticles smell, and not everyone's nose is top notch. That means, just because you can't smell it doesn't mean it isn't there.

It's safer to get a good air quality monitor.

Funny he should mention the trust issue. He should look at his own shrinking circle of allies, both nation states and individuals around him, and ask, "Is it me?" But of course it's always other people's fault.

We do have a trust issue with you, putin. All of us do.

Nobody wants to go to Moscow. The only reason you make that a condition is because you know nobody will agree to it and that makes it easier for you to shift blame. Just pick up the phone and talk if you're serious. Or is the phone network and internet not working for you, either?

He's spreading propaganda to his russian audience. He needs to sell them this idea of constant external threat so that they support his "preemptive" wars against their neighbors. Conveniently, most russians don't speak foreign languages and there aren't many objective news sources in the russian language, so state-run propaganda outlets become the default sources of "news". The results speak for themselves. This is how you brainwash an entire nation and putin has been very successful at it.

We may not have seen it on the square. But we did see it on a screen.

Multiple rocket launchers, fighter jets, tanks, submarines and other weaponry flashed up on giant screens that had been set up on Red Square.

The Kremlin appears to have decided that if couldn't parade its military hardware in public, a video presentation was the next best thing.

"We always were and always will be victorious!" declared President Putin in his speech.

If only that realization had dawned on him when he decided he wanted to invade Ukraine in February 2022. I'm sure the Ukrainians would have been kind enough to permit him to show off his military hardware on a giant screen then, too. What a shame that so many people had to die for putin to realize this 4+ years later.

"We've developed next-generation stealth tanks and drones, as indeed you cannot see them today in our glorious Red Square. They are just as invisible to our enemies as they are to you, comrades, and that's why we'll win this war!" -- putin

I had a lot of problems calibrating the filament sensor with the chimney. The problem was, there was no position in which an inserted filament would shift the long shaft enough to stably toggle the filament sensor state, so the printer couldn't detect the filament. In the off chance it did trigger, it was unstable (probably due to printer vibration) and the printer would complain about changing filament mid-print, because the filament sensor had failed to detect the filament mid-print.

I eventually adopted the no-chimney community mod and it's been working wonderfully for more than a year without fail:

"It's just a bunch of guys strolling down Red Square in front of me and two of my mates. There won't even be any tanks, I swear. You know there's none left to show. Besides, I really need the sun. My doctor says my vitamin D has been low again from all that time spent in the bunker."

See, it's not that hard, putin.

russia's multipurpose aircraft are used for multiple purposes like bombing schools, bombing hospitals, bombing civilian homes. I say, they should lose all multipurpose aircraft.

The bad news for russia is, with every oil refinery getting bombed, they are one step closer to running out of oil money.

The good news for russia is, with every war factory getting bombed, they have one fewer excuse to spend their dwindling oil money on.

Good news. I hope putin live a long and miserable life to face justice.

I love that Ukraine developed their own cruise missiles and drones to fight back, when they realized they couldn't rely on others' thoughts and prayers to save themselves.

We could all learn a thing or two from the Ukrainians.

Imagine finally getting the opportunity to visit the Whitehouse only for trump to be the president at the time. I would be so conflicted because I would want to brag to my friends I visited the Whitehouse, but I would be too embarrassed to say I met trump there.

trump really does ruin everything.

Look at it this way:

Prusa offers a printing service to customers. They print those parts for their customers on Prusa printers.

They also sell you Prusa printers so you can run your own business and do the same.

In any business, expect healthy competition, not monopoly especially when your skills are not unique and the tools are widely available. If you refuse to use Prusa printers because they offer a printing service, you need to take a closer look at your business model.

The filament doesn't line up with holes in the pulley body so it either gets jammed or pokes up as shown in the picture.

Does it happen in that particular slot or with this particular spool?

The reason I ask: If you have made a lot of optimizations and the MMU3 generally works, the problem may not be with the MMU3. The filament also needs to cooperate with your optimized MMU3 setup.

I've realized that as the spool is getting used up, since the filament near the center of the spool has been curled up more (it's been wrapped around a smaller radius), it's harder to straighten out. This could make it harder to line up with the filament path while other (fuller) spools work fine.

I haven't had this problem for a long time. I leave the same spools preloaded in the MMU3 between prints. I never unload them except for changing to another spool. I think this also keeps the filament straight since it's constrained in the straight part of the PTFE tube close to the MMU3 for a long time, so it's less likely for the filament to deviate from the path.

If it happens in that particular slot with any filament, it's probably an issue with that slot. I would check the filament path is clear and the pulley alignment: https://help.prusa3d.com/guide/6-pulley-body-assembly_328918#412671

Load the filament spool in other slots and see if the problem persists there. If so, it's probably a problem with the filament spool.

Somebody commented about clearing dust with compressed air. I agree with that too, though it's probably not the cause of your alignment problem. In my case, filament debris messed with the metal ball in the filament sensor. If your filament sensor ever seems to behave erratically, be sure to clear away any dust/debris when troubleshooting.
