Expect 25% faster moves and maybe some other issues. + +Using lcd and sdcard support on an ATMega644(P) is not possible cause the sketch is way too big for its memory. +I switched to an ATMega1284P which has double size program memory. Unfortunately it's not supported in Arduino IDE out of the box but expect a tutorial on how to compile for it soon. +For the necessary pin breakouts I used Alfons3 design of GEN7 (https://github.com/Alfons3/Generation_7_Electronics) with an additional breakout for pin A0/D31. +I'll publish my desing as soon as possible. + +Expect this fork to be highly experimental. + WARNING: -------- THIS IS RELEASE CANDIDATE 1 FOR MARLIN 1.0.0
