Machine Won't Move!

You've sent G28 and the machine still won't move using the jog buttons. Take a look at the
serial terminal output. You may be seeing an error go by that looks like this:
What is most likely happening is that you haven't yet plugged the hot-end thermistor in. The
firmware is preventing the machine from moving because of this – it's a safety measure of sorts. A cold
thermistor will read ambient room temperature, but a failed one may not – it could read zero or some
very high number. The firmware is will prevent the Rostock MAX from operating if the thermistor
readings are below 3 degrees Celsius for the hot end and heated bed, or if the hot end temp is above
275 or the heated bed is above 140. (These are defaults and shouldn't be messed with unless you know
exactly what you're doing)

LCD Panel Not Working

The LCD interface in the Rostock MAX v2 is a pretty simple device – there's not a whole lot
that can go wrong with it. The most common issues involve either the display not lighting up or the
knob not properly operating. Both of these issues boil down to a wiring issue. Remember, before
working on your Rostock MAX v2, make sure you turn off the power!
First, check to make sure that the small interface PCB is properly installed on the RAMBo. It's
pretty easy to get it on there shifted to the left or right by one pin. (Rare, but it can happen.)
Next, you need to make sure you've got the cabling between the LCD and the interface board
installed properly.
If you've got an LCD controller that has a white PCB, you'll need to make sure that the red
stripe on the ribbon cables are on the right side as shown below.
Cabling for white PCB.
