The signals are quite susceptible to noise, especially if the ribbon cable is long. Try to keep them away from the other wires.

Also, Marlin is under heavy development at the moment and bugs may be creeping in. This is primarily why I have not updated my fork for a while.

As a side project I will be taking a look at configuring aprinter for the Mendel90 as an alternative firmware.
