So I brought a "EINSY" board http://reprap.org/wiki/EinsyRambo (the one in the Prusa MK3) since I kinda wanted a Prusa but didn't want to buy a Prusa. I've spent some time with it on my M2E and so far I'm in love with it, I highly recommend this board! Here's my thoughts so far:
Pluses:
Quiet even in speadCycle mode.
Sensorless homing is wonderful.
The Trinamic 2130s seem to produce a better quality print.
Stepper motors run cooler.
Negatives:
All the fan outputs are 5v. This is the apparent reason why Prusa is using the Noctua fans. I have a 40mm Noctua and that one seems to be fine for the extruder, but the 5v that I have for my part cooling seems a little inadequate.
The REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER I have for the display is a bit garbled, it still works but it's a tad annoying.
Here's a photo of the board wiring is messy at the moment:
Sample print but this is with the 5v fan and you can see cooling artifacts in it:
Garbled screen:
Things left to do / research:
I'll look for a fix for the screen, but I really don't use it that much since I use OctoPi so I may even remove it.
Find a 5v fan that outputs adequate cooling or I may go with a MOSFET solution and use VCC for the fan.
I would highly recommend the MG guys to look into this solution for one of their future printers!
