A Kinen Fin to add support for 3D printer Extuder and Heated bed to a Kinen compatible TinyG board. This project is a redesign of the first Kinen fin for temperature control on the kinen platform found here https://github.com/Kinen/TempFin1 . This redesign transitions the platform away from the Atmel 328p to A FreeScale ARM Cortex M0+ for more performane per dollar. The system wide reset is now jumperable so that the fin and the motherboard can be programmed/reset independently of eachother.
