I would like to build a Cherry Pi III "ish" delta printer.  I will use many of the parts and idea from [[http://forums.reprap.org/read.php?178,361141|this forum]].  And [[http://www.thingiverse.com/thing:344408|this thingiverse page]].

   * 5/22/2015 
     * Printed [[http://www.thingiverse.com/thing:126778|Airtripper Bowden Extruder BSP Edition]]
       * [[http://youtu.be/ziopiy626Cs]] Here is a timelapse of these parts
     * Printed 4x [[http://www.thingiverse.com/thing:487476|Mini V Wheel Carriage for OpenBuild Extrusions]]
       * Chose to print 4, so I'd have a spare, and because it lined up nicely on the plate (probably a wasted part)
     * Aluminum Extrusion, and Mini V-Wheel kits showed arrived from OpenBuild  
     * Tested AstroBox / AstroPrint.  My thoughts are to currently avoid this
       * The setup and web ui were very nice.
       * It doesn't support streaming video which is a deal breaker.
       * It can talk to your machine from the cloud, no obvious way to turn that off
       * Raspberry Pi camera is not supported
   * 5/21/2015 Some parts started to arrive, such as stepper motors and some screws and nuts. 
   * 5/20/2015 3D printed parts for base.

   * 5/18/2015 Start of the Cherry Pi III project
     * Ordered Many Many parts online most were sourced from eBay, Amazon, or openbuilds.com

Sourcing a few parts have been difficult
  * Magnetic balls
    * http://www.magnet4less.com/ need to figure out what to order

Extruder:
Tim recomended the [[http://www.thingiverse.com/thing:126778|Airtripper Bowden Extruder BSP Edition]]



I like this [[http://www.thingiverse.com/thing:651472|Lightweight end effector plate for Delta]] But it would need various  modifications depending on what we attach to it.

Interesting ideas

the adjustment you need to make for size of parts (once you have your Z correct) is the delta rod length. You can use Rich's M666 command for that. The formula is (measured length/specified length) x delta rod length = new delta rod length

tips... fan motor not spinning
If you rotate the magnets you will find a 'sweet spot' where they don't cause this issue. I had the same problem on the original Cherry Pi.

Slicing

Andy: I use 0.3mm layer height and 33% in fill on virtually all my printed parts. The effector, which is the only ABS part, I print at 0.2mm layer height.

I have been using slic3r with a .3mm layer height and a 20% infill.  I've been printing all parts in ABS

Notes:
It appears a different size carriage will be needed for the v-slot extrusions:
