Also, social media influencer drama is pathetic in general.

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.

- Comment on The Prusa Mk4 has done it again ☹️ 3 days ago:
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.

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 head 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 print 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…
- Comment on Is there enough filament to complete the print? 4 days ago:
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.
- Comment on Is there enough filament to complete the print? 4 days ago:
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. - Comment on The Prusa Mk4 has done it again ☹️ 4 days ago:
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 🙂
- Comment on The Prusa Mk4 has done it again ☹️ 4 days ago:
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?
- Comment on Is there enough filament to complete the print? 4 days ago:
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!

Trump’s loss in support among Hispanic and young adults has been especially steep.
I have no respect for Trump voters, and I especially have no respect for hispanic Trump voters, who should have known better.

Americans should be concerned about Trump and his goons first and foremost - the “homegrown” criminal gang.
Seriously, had you heard about MS-13 before Trump?

- Comment on The magnetic printing plate shifted early in the print - or something else happened? 5 days ago:
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’ve done that a few days ago.
The belts might be getting lose 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 just fine.
- Comment on The magnetic printing plate shifted early in the print - or something else happened? 5 days ago:
The plate does indeed stick very strongly against the bed. The magnets are fine.
The most plausible explanation I have is that someone stuck their hand in the enclosure for some unexplainable reason and the bed hit their arm or something. The only problem with this theory is, there is zerro reason for anybody to do that. But I did start the print early enough for a few people to still be at work when it happened.
Other than that, I’ve taken to using glue on the plate lately, because I’ve had adhesion problems. Maybe some leftover glue turned liquid-ish and degraded into some sort of lubricant with the heat (I’m printing PETG with the bed heated at 85C) and it seeped between the bed and the plate. I’ve never felt it was ever slippery though.
Or it was some leftover water that steamed over between the bed and the plate and lifted the plate for a second, air-hockey stylee.
None of this seems very likely though. So I cleaned the bed and the plate real thoroughly, installed the plate tight against the registration pins, upgraded the firmware to the latest for good measure, slathered glue super-carefully all over the plate, making sure it didn’t go overboard, and started the same print once more. I’m watching it remotely through the webcam I installed in the enclosure and it seems to be going fine:

It’s a major blow to forgetful frequent flyers too: giant Toblerones are famously what you can always find in any airport to buy someone you completely forgot to buy something for and pretend you didn’t forget.

- Comment on How Elon Musk's favorite news influencer is capitalizing on his clout 6 days ago:
The only reason Musk has influence is because he has an audience on Twitter. The only reason he has an audience is because people are willing to listen to what he has to say.
The questions is: who the fuck is interested in what Elon Musk has to say?
Unfollow him - or whatever ignoring someone on Twitter entails, I’ve never been on Twitter so I don’t know - and Musk will find himself deprived of influence. Just like that.
