Everything is parallel

Posted on October 6, 2016 by paulwallich

Or at least multithreaded. I was prototyping some vaguely image-related ideas in Processing, and decided that I wanted to pick which image file I was going to mess with on the fly rather than hard-coding the filename and path into … Continue reading →

I like Octoprint

Posted on February 15, 2016 by paulwallich

So I was sitting upstairs where it’s warm, instead of down in the cold basement, and suddenly I had the idea to print something I’ve been noodling on for a while. Click. Click. Click. Move the Octoprint browser window so … Continue reading →

more heated chamber

Posted on January 13, 2016 by paulwallich

I think this is a pretty good indicator. Both prints using the same spool of ABS (which my friend Tyler at filabot dropped off for playing with because of the nonuniform color). Right without a chamber, left with chamber. The … Continue reading →

printrbot metal plus heated chamber

Posted on January 12, 2016 by paulwallich

I think I could make this one a little better, but only at the cost of making it much harder to watch prints in progress. It’s got an outer frame of bent 3x12mm aluminum strip that clamps itself to the … Continue reading →

Sometimes it’s just nice to have the right tool

Posted on December 11, 2015 by paulwallich

It’s holiday-cookie time, and the new beater we got for our 15-year-old stand mixer didn’t fit. It went partway on the shaft and then jammed. Grr. So this morning I went down to the basement and over to the old … Continue reading →

More Big-Nozzle Fun

Posted on December 4, 2015 by paulwallich

This may actually be useful for other people. When I went to test different extrusion speeds for my 0.75mm nozzle on the Ubis13 I was concerned about how fast I could go and still have the heater keep up with … Continue reading →

3D printer nozzle wars

Posted on November 30, 2015 by paulwallich

I finally got around to trying the  0.75mm nozzle on my Metal Plus. It arrived before the holiday, but I didn’t have the time to make a custom wrench for it (the flats appear to be just a hair too … Continue reading →

Bending acrylic is easier than I thought

Posted on November 11, 2015 by paulwallich

This summer I took the little radiant space heater down from the ceiling of the woodshop — it really wasn’t doing much to keep me warm out there.  And we’ve had the scraps of a bunch of broken acrylic storage … Continue reading →

Ubis 13: Just a better hot-end?

Posted on October 6, 2015 by paulwallich

So the all-metal hot-ends finally arrived, and I fixed the Metal Plus so I could actually use them, and I’m a convert. First, of course they make it possible for me to print with filaments I couldn’t use before, like … Continue reading →

Yet another tiny robotic car

Posted on September 9, 2015 by paulwallich

Yes, it’s made mostly out of random parts I had lying around. That’s sort of the point: even if you had to buy all the parts, this thing would be cheap, and if (like me) you accumulate toy and electronic … Continue reading →
