Kit assembly woes

I just finished assembling my Mk2 kit - but I am running into various issues post assembly.

First, turning the pot on the LCD screen does not scroll through the menu. Nor does the SD card reader seem to work. I checked multiple times if the wiriing is correct, and even did a continuity test on each individual wire in the ribbon cable to check for faults. Needless to say I emailed Prusa to get some help.

The next issue I am running into is connecting the Mk2 to Prontrface / Simplify3D via USB to do my own selftests (since I can't initiate it from the LCD at this time). I installed the drivers, and I am able to connect to the machine, but its not reporting any temperatures, and I am not able to interact with the machine at all. While the LCD was connected (I took it off until I can get it fixed) - it reported temperatures around 30C. According to the Troubleshooting video, that should be correct. To be extra sure its not the thermistor wire - I connected my existing E3D v6 from my other printer (which I know works) - and it also didn't report any temperatures in either application.

Lastly, the inductive PINDA probe seems to be triggered (red light is on). From my experience with Printrbot - the light should only be one if it senses metal. The probe is no where close to any metal parts

Anyone experienced anything like this?

Ok - so I just managed to fix all the issues I listed above.

1. The reason the applications didn't report any temperatures was due to the initial message you get the first time you power up your machine - something in the lines of "The printer hasn't been calibrated - check the manual...." This message needs to be dismissed before anything is reported over USB

2. For some reason that defies all logic - after connecting my printer to USB, and dismissing the message, my LCD pot just started working by itself. Nothing's changed - so I don't understand how doing this made it work. Hopefully if someone else has this issue they can try this as well

That's OK, inductive probe works with inverted logic. The LED is on when the probe is NOT triggered.
