      Looking for a set of lasercut parts to build one? Clockwerk Mech offering at $400 incl shipping in the US
      Now that FreeBurn-1 is up and running (see http://openbuilds.com/builds/openbuilds-freeburn-1-v-slot-co2-laser-60-100w.1001/)

      I think it's time to start working on my 4th iteration of a lasercutter design: FreeBurn-2-Mini

      The Mini is a much smaller (900x650mm desktop footprint) machine that offers approximately 600x400mm work area, with a 40-50w tube (larger tubes need a longer body - so you would be better off building a FreeBurn-1 style machine if you want higher wattage)

      Furthermore, the Mini will use a lot more lasercut/waterjetted metal sheeting (yes I hear you - but trust me every big town has a shop just hunt them down) with some strategic bends. Also, a BIG challenge is to make the whole design be bolt-together. If I could use spot welds my job would be a lot easier but then that would make reproducing the machine / packing as a kit / later disassembly impossible - and I'm not prepared to compromise those. No the FreeBurn-2 Mini will need nothing but a few bolts to assemble!

      The sheetmetal frame will be easier to align than a FreeBurn-v1

      So where do we kickoff this project?

      1. 20 Jan 2015: Release the first render
      2. 20-25 Jan 2015: Cleanup design - all those buttjoints have to change to planned bends with radii allowances and holes so all the panels can bolt together. I also need to draw the lid and z axis
      3. Jan-Feb - finish drawings and ordered first prototype, plugin for sketchup to laser-gcode, etc - see the discussions tab for details
      4. 19 Feb 2015: Alpha machine frame built! Released beta files for early adopters
      5. 9 March 2015: Electronics prototype phase
      6. On the hunt for a cheap US based supplier to lasercut and bend frames.
      7. Saving up for the tube + PSU

      8. April 2014 - first movements

      9. April 2014 - kickoff efforts to build a ChiliPeppr.com workspace to control the machine with
