TINYenormous – Build it up to break it down again

Here’s an overview shot of the prusa, E-stop switch, and macbook. I still have to build the bed, but the rest is all there. Yesterday I flashed it with the sprinter firmware and I like it so far! The biggest thing is that it has acceleration. That enables lower torque motors to start slow and …

I’m not sure what’s been going on with my makerbot, but I don’t like the way it has been progressing! All week long I have been having trouble with my extruder board. I’ve been talking with Matt at Makerbot and he has been super helpful, but we haven’t figured it out yet. It will give …
I can’t believe it took this long, but I finally had a bad filament tangle last week, and a few aborted prints because my old setup wasn’t working. I really needed to get my filament spooled so that it would nicely dispense, and not jam, tangle, or unspool. I really love the way the official …
It all came down to this… When I assembled the extruder (makerbot mk4) the allen wrench that came with the kit never felt right. Regardless I tightened the set screws on the gear until the allen wrench felt like it was about to strip it, and then I went on my merry way. After watching …
Let’s give this a try! Tonight I prepped 4 3ohm 10 watt aluminum resistors with in two parallel pairs with solid copper wire. I gave it 12 volts of juice and it got plenty hot quickly, so hopefully this back of the matchbook effort will pay off. I don’t have the aluminum plate with me, …

As I’ve been blogging, my makerbot is sick (as in broken). Yesterday as a fun distraction I ran across the makerbot music page. Thankfully you don’t need an extruder in order to make music, so I dropped the lady Gaga “bad romance” gcode onto my bot and hit run. It was a good break, and …
I recently bought a molded reprap prusa mendel kit from Metrix create space. They are a hacker space in Seattle, Wa. The molded kits cost anywhere from a third to half of what a set of printed parts cost because they take far less time to produce. One downside of the printing method is that …

I’ve only had the makerbot for a month now, but it’s refusing to print. Sigh. I know it’s a diy kit, but this little puppy only had three whistles printed on it before it rolled over, ready to die. Here is my thought process as I go about trying to fix it. Symptoms: The extruder …
I really enjoy building mechanical movements, and I am terrible at it. It is really difficult to build things that move without relying on expensive pre-built mechanisms. Thus I am always looking for cheap ways to design and build cogs, gears, and sprockets.
After breaking my makerbot extruder head I decided I wanted to try my hand at making one from scratch. It’s a brass m6 tube with a nozzle screwed onto one end. How hard can it be! It turns out it’s really hard, but I ended up having luck with a technique called the “afghan lathe” …
