Note on Cricut CRV001 Hardware

A project log for Cricut Hacking

Putting Marlin 2.x on the Cricut Expression because, well, why not? Also, some reverse engineering on CRV001

In case someone else is playing with this. The CRV001 has an ATMega128 MCU (fewer timers), a 1x16ish LCD. The steppers work the exact same, the pen test sketch doesn't work at all (it's doing something, but I can't tell what) and the LCD sure seems to be a 4 bit parallel style. Hopefully more on that later.
