She must have been one of the alien enemy toddlers mentioned in the Alien Enemies Act.

Do we call ICE the Gestapo now or is it too soon?

Also, as cars designed by immature adults go, it might just look better than the real thing.

AI & AGI have me kinda terrified

If you’re young, you should be.

I’m not and I’m nearing the end of my professional career. Even if I get the sack tomorrow, I’ve had a very good run. And I have other skills that simply can’t be replaced by AI or robots, so I’m not really worried. Concerned, yes. But not worried.

But I know I won’t have any retirement, that’s for damn sure. Still, it beats not having any professional prospects from the get-go.

All new technologies eventually displace obsolete jobs. But crucially, they usually do it slowly enough that the workers whose jobs are being obsoleted aren’t all sacked virtually overnight (i.e. society has the time to evolve relatively peacefully) and more of the new and better paying jobs are created for newer generations.

The internet is no different. My Grandpa was a telegraph operator. My Father worked for AT&T installing landlines and I’m a computer guy. Both their jobs are virtually gone and mine will be soon. But I did manage to make a career out of it.

The first real, violent disruption is happening now however: AI is on the verge of obsoleting a MAJORITY of all jobs within a few years, and no new jobs are really created to replace them. Society will be deeply uprooted and won’t have time to prepare for the shift. A lot of people will lose their jobs with no alternatives to put food on the table. That’s a recipe for war.

The saving grace for postal services is the rise of online stores like Amazon. They all shifted from delivering mail to delivering parcels.

When the issuer of the executive orders ignores court rulings, it’s completely irrelevant.

They chose to sleep in somebody else’s bed and they shat it. What did they expect? Twitter isn’t some public agora where free speech is guaranteed or even expected.

Also, social media influencer drama is pathetic in general.

Well, look at the bright side: if they’re allowed to stay here, they can always apply for a job in Florida.

Also, they should count themselves among the lucky few who didn’t get shipped off to a Salvadorian concentration camp without ever seeing a judge.

This is America, and this is the 21st century. Doesn’t that blow your mind? Cuz it sure does mine…

Ooh that’s clever. And I have just the part to test this - a big clamp that needs to hold a part together in 2 axes and regular breaks on the axis that was printed vertically.

Okay so I’ve readjusted the belts’ tension this morning. The X belt was a bit loose and the Y belt was a bit too tight, strangely enough. Both in the green though. So I set them to the middle of the range. Good thing I checked anyway because all the screws on the X motor mount were so loose they were on the verge of letting go completely.

And since I was at it, I cleaned the entire enclosure and re-lubed the rails and the linear bearings.

However, I don’t think the printer faulted because of any of this: I checked where the hard limit was in X and Y and found that the nozzle came right at the edge of the previous prints that failed on the left and on the top:

At this point, I’m convinced the printer got lucky twice when it printed that print right, and when it didn’t, it was the result of the carriage hitting the limits when the motor(s) overshot the extreme positions a bit. I re-sliced that print to leave some margin with what PrusaSlicer believes are the limits of the printing area and I came to a perfectly printed set of parts today. And the new set I started 2 hours ago seems fine too.

So I think the lesson here is that PrusaSlicer is a bit too optimistic with how large you can print, both in X and Y. It pays not to believe it too much.

EDIT: 6 hours later, another perfect batch. So I think my theory is confirmed.

Grid infill is crossing, get a decent blob or buildup and you could have nozzle collision, I personally like gyroid but it is slower.

I’ve had the extruder collide into blob on solid infills (or perimeters) when the filament was too hot - usually TPU or TPE - but never infill. I’ll give gyroid a spin though.

prusa has an article for troubleshooting layer shifting

That’s a great article. Thanks!

I’ll go check everything tomorrow. The thing is, it’s the first time this happens (well, second time now). The only unusual thing I did compared to previous prints was fill the bed to the brim, right up to the edges as allowed by PrusaSlicer. I’ve corrected that to make sure this isn’t the issue. Other than that, it’s a printer that’s been printing all day every day for a good year and a half. So yeah, it probably needs some TLC at some point…

Interesting. I’ll have to try the reverse experiment: I have a roll of TPE that’s been drying in the dryer for at least 3 weeks. I’ll take it out and see how fast it’ll reabsorbs water.

How much weight difference do you see? Do you simply wait for the weight to stop changing?
Good thinking. I didn’t think about that.

My company is flexible, but ultimately this is not my printer and I want to ask permission to undertake maintenance. For all I know, whoever ordered it in the first place is in fact in charge of it, or maybe they want a 3rd party to do it. It’s just a matter of talking to the boss and making sure what I’m about to do is approved 🙂

Turn this (ramping lift) Off/On or tweak the settings

Before doing any of that, I’ll run several prints of the new parts layout that aren’t quite so close to the edges of the bed. The one currently printing is going well so far.

I really have a strong hunch that it’s just a matter of not using quite as much of the bed surface as PrusaSlicer thinks is usable safely.

Oh and i wouldnt use grid as infill

Why is that?

Yes, it’s obvious. But maybe it’s useful to those who didn’t think about it? Sometimes the most obvious things are the easiest to miss.

I’m sorry you feel so negative about it.

This is the company’s printer. I’ll have to get the expense approved first.

Assuming it needs servicing of course: I have to keep cranking out these adapter plates as fast as possible right now, and something tells me not going so close to the edges of the bed will help. It wouldn’t be the first firmware bug I hit in this printer…

Thanks for the tip!

The idler is gripping the filament just fine. I know that because I have to loosen it when I print really soft TPE and I tighten it back up and readjust the idler pressure when I print PLA or PETG - and I did that a few days ago.

The belts might be getting loose though. I haven’t checked them. They look tight but the printer has a lot of mileage, so I guess it’s worth checkout out. But the re-print I just did of the same bgcode just completed fine.

I do have a camera but it doesn’t record.

If it was a nozzle hit, it was a violent one: this was 8 separate parts printing on the same plate and all 8 parts were similarly shifted - meaning the plate itself had shifted underneath, or both motors skipped or lost their origins. So I don’t think the nozzle hit anything.

The filament is PETG, but I don’t think it matters. The prints don’t lift off the bed because I use glue.
