3D Printer

I have a Prusa i3 3D printer that I purchased from Hong Kong a few years ago. It was a DIY kit costing around 280.- USD at the time. The printer was good value,┬ábut I ran into several problems with it’s control system. The one I use is based on Arduino, but with re-designed electronics so you get an all-in-one system that is based on Atmega2560.

Moving on I wanted to re-write the firmware package, but I also want to upgrade my printer with more advanced features than my current hardware will allow.

  1. Scalability to add more control IO to expand the printer’s capabilities.
  2. Proper firmware package that is well designed, easy to maintain and not riddled with real-time issues.
  3. Ethernet wired and wireless.
  4. Proper printer queue solutions.
  5. I want to target CNC machinery in general, not only 3D printers.

Using the current Prusa i3 as a starting point I need the following:

  1. 5 axis on standard RAMPS or equal.
  2. 3 end-stop switches.
  3. 2 temperature sensors.
  4. 2 heaters.
  5. 1 fan.
  6. USB serial solution.

I want to build this on top of my current system with Hat’s and RS-X modules, so it’s more an issue of what do I need to add on electronics. Also keep in mind that I still have my 6 legged robot in mind as I create modules.

The major benefit of this system is that we enable people to build and experiment themselves on plug & play level rather than creating Yet Another 3D Printer Control System.
