Progenitor of the Weird Knife Wednesday feature column. Is “column” the right word? Anyway, apparently I also coined the Very Specific Object nomenclature now sporadically used in the 3D printing community. Yeah, that was me. This must be how Cory Doctorow feels all the time these days.

  • I can’t speak for other printers, but my X-Max 3 has an absurdly thick aluminum plate under there which seems to spread the heat pretty well. I’ve poked it with my little IR camera and it’s not 100% even but it’s not bad. The only side effect of this is that it takes a month of Sundays to fully reach temperature, especially when you’re aiming for higher temperature materials like ABS.

    Here it is on today’s preheat for PLA:

    (IR cat tax paid here.)



  • DVI is not supposed to carry audio, but in practice in many cases it does. That’s because internally both devices are likely to implement DVI by just shoving an HDMI output through the connector anyway. The jury is out on whether or not this has any licensing implications. I’ll be damned if I know, because I was always under the impression that the part that incurred licensing fees was the HDMI port itself.

    I rediscover this fun fact a couple of times every year when one of our office machines decides to randomly start piping its audio out of the monitor sounding like a mouse trying to play the kazoo through its sinuses rather than the speakers that are right there, and somebody complains at me and I have to schlep over there and switch the audio output back.

    Apparently this is expected enough behavior that cheap bottom of the barrel PC monitors bother to include speakers for it.





  • It certainly makes it easier to photograph, or at least to find with the autofocus.

    There are also two color blemishes on the top surface which I’m a little miffed about, since these were defects directly in the spool of filament. It must have been made with like two pellets of the wrong stuff in the hopper.

    Oh well. It’s a tool, it’s not like I’m hanging it up on the wall in a frame or something.





  • Getting away with it so far. We’re just about done with the bottom deck and about to move on to the vertical walls. Apparently the entire thing has in fact not folded up like a taco and come off of the print bed, so that’s nice.

    The layer on top of the short section of infill covering the entire tray transitioning to the top fill is easily the longest time spent on a single layer I’ve ever seen in my life. I think it took more time than the first layer.
