The failed printer


If you’ve been to this page earlier or come by using old search references left from my old site you probably remember me buying a TechZone Huxley 3D printer. And if you wondering what happened to it, here’s a quick summary:

  • When I first got the package a couple of parts were damaged, mostly the build bed. So I had to make a new one.
  • A lot of the important structural pieces was too small, machine had to be reduced in size to be able to be assembled.
  • One of the timing belts was way too short, had to fix it with a couple of zip ties so it could reach around.
  • Many of the printed pieces was poorly made with warping and shifting.
  • The Z axis cogwheel was failing due to both warping and shifting, timing belt slipped constantly during -Z motion.
  • Drive gears in general slipped now and then.
  • The hot end was catastrophically damaged during testing due to faulty tolerance in the ABS filament (My bad!). The hot end was pushed out of the Teflon holder and since I couldn’t do anything to fix it I ordered a new and better hot end.
  • When I installed the new hot end I tested it out extensively and all looked good.
  • After mounting the hot end back onto the machine with some minor modifications I was ready to test it out once more.
  • Temperature sensor suddenly didn’t work and the hot end wouldn’t heat up.
  • Then the controller board popped and smoked.
  • The machine was then disassembled.

So after all the hard work trying to put the damned machine together I never did make it work, and each time I thought to myself that I finally had everything done right something nasty would happen. Now that was about 3 years ago, and the market for 3D printers have changed dramatically. So many new printers out there it feels much safer to get out there and try again, the machines are cheaper, better built and a lot of changes to the designs have happened. Just look at the Orion Delta from SeeMeCNC. Using better construction materials instead of relying in stuff bought from the nearest hardware store really makes everything easier to put together.

So when I was searching for a new 3D printer to buy I had a couple of different machines to choose from, and I wanted a small and portable machine with “OK” print space for a decent price. There was some machines out there that I really would like to own, but they were way to expensive. I’m going to use it for fun/hobbies and so on.

 

I finally went for the MakiBox A6 HT because it seem to be very easily assembled. The man behind it built one in about 2 hours, so for someone who hasn’t the experience he has still should be able to do it in one day, and not in a couple of weeks like the machines earlier.

There are still some “bugs” in the design, but they seem to be minor and constantly fixed and upgraded by both the developers and the community. I really want to start printing parts now. 😛
