| - | 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]]. | ||

| - | * 5/20/2015 3D printed parts for base. | ||

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

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

| - | Many parts were sourced from eBay, Amazon, or openbuilds.com | ||

| - | 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. | ||

| - | 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. | ||

| - | 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. | ||

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