 +       * 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.

 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 the adjustment you need to make for size of parts (once you have your Z correct) is the delta rod length.

 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. 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.

 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. Andy: I use 0.3mm layer height and 33% in fill on virtually all my printed parts.

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