Kossel 2500 3D printer build

Why has it taken me so long to decide to build a 3d printer? Better late than never I guess… Time to get started!

After some research, I decided to build a delta printer based on the Kossel design. We use a lot of delta robots at work in packaging an they are very fascinating to watch. Whats a delta robot?

I’ve been trolling the Google delta printers group for information. A user on the group builds and sells carbon fiber arms with magnetic joints and I decided to purchase a set from him rather than try to build them myself. The length of the arms, particularly the consistency in length is very important to the geometry for print quality and accuracy, so I figured I shouldn’t skimp on this part. I ordered the arms on Monday and received them on Friday. Lighting fast shipping from Hawaii, awesome!


The arms are labeled with their length and are all within .01 mm.

Raspberry Pi webserver


Yes, this website is was running on a $35 Raspberry Pi!  A Pi is a small (a little bigger than a credit card), single board computer that runs Linux.  I had an extra Pi and thought that this would be a good use for it.

Update – I ran the site for about 6 months or so on the Pi.  I would have to reboot it or restart apache about once a week.  I needed the Pi for another project so I moved the site to another computer.
