 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 encountered some major problems with the Z motors and manual control rendering the board impossible to use. As I thought the board was defective I sent it back to shop for revision and testing. They found no fault on the stepper drivers so they sent it back. 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.

 Jenny still runs on the good old Mega + Ramps with a 2.0+ marlin firmware.
 She also has brand new stepper motors for controlling X, Y and Z.

+==== New Fan Duct ====
+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.

+It requires supports to print but does it's job perfectly.

   * Lookout for resonance on the cooler radial fan
-  * Upgrade to a smoothie board
   * Measure % offset on size to get exact dimensions -> print test part, measure, compensate x,y,z, print again
   * Update wiki with Marlin firmware (latest), a backup of Printer/Prusament profiles for prusa-slicer, etc..
