I tested it out but the eMotronic board I ordered differs from the smoothieboard project in a few ways. First, the entire PCB was redesigned by eMotion Tech and most of the pin numbers were reaffected. Documentation of the eMotronic is at the time of writing rather poor and scarce. | I tested it out but the eMotronic board I ordered differs from the smoothieboard project in a few ways.

- | In the meantime, I have reverted Jenny back to the good old Mega + Ramps marlin-based controller. | + | **As it turns out the eMotronic board takes many liberties with the original smoothieboard design and is not an easy implementation on an i3-type architecture.** |

+ | I redesigned the fan duct of the radial fan cooling the print. The problem with the first design was the large flat bottom surface too close to the print that would hit on any print part warping during print. | ||
