After that check for broken solder connections on the part - you can also try faking pulses by dabbing with a probe - are you confident with a soldering iron?

Cheerio,

I went to restart everything and get it cleaned up and noticed that the rotary knob is not functioning, it clicks and sounds normal, but I cannot move through the menu settings aside from clicking the knob in. 

I had a spare LCD control board and I plugged that in to no eval. I thought this may be a firmware issue until I connected it to octoprint and was able to control the printer as normal (all steppers move). 

any ideas? I might think about flashing firmware again.
