  • “We are going to have a crash and we’re going to have a crash like a 1929 crash if she gets in,” the Republican nominee warned, referring to the Great Depression.

    Perhaps Trump identifies as a woman and referred to himself.

  • I think HBO thinks they have a great asset because Maher can still pretend he's left wing on the surface (getting thinner by the minute though) and suck up to Trump and the magats at the same time. So HBO nurtures him and his show to hedge their bets.

  • I quit finding Bill Maher funny years ago, and I can see right through his "I'll talk to anyone" shtick: the man is basically MAGA-adjacent to put it kindly, and his vehement and frequent critique of Trump and MAGA is just a distraction.

    That's why Trump invited him to dinner: Maher is the useful pseudo left-wing pundit whom he hopes will legitimize him.

    Fuck Bill Maher.

  • NonPlanar Interlocking Walls for Stronger 3D-Prints

  • 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.

  • The Prusa Mk4 has done it again ☹️

  • 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...

  • Is there enough filament to complete the print?

    Jump

  • 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?

  • Is there enough filament to complete the print?

    Jump

  • 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.

    Jump

  • 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 ignores the Supreme Court. Fat lot of good this will do: the Supreme Court justices had better get used to being frustrated.

  • This professor studies dictatorships. He helped convince Harvard to stand up to Trump

    Jump

  • I agree. It's just that resistance should be uplifting, and seeing that, once again, only the rich have the means to resist is depressing AF.

  • The magnetic printing plate shifted early in the print - or something else happened?

    Jump

  • 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.

  • This professor studies dictatorships. He helped convince Harvard to stand up to Trump

    Jump

  • Their pressure seems to have helped Harvard President Alan Garber stand up to Trump

    No: what helps Harvard stand up to Trump is that Harvard is loaded. The University of Bumfuck Nowhere will immediately cave in to Trump's authoritarian nonsense to maintain their federal funding and their tax-exempt status. Harvard can afford to do without them.

    In other words, I'm glad Harvard is resisting. But this is yet another example of rich-man-can-do.
