That doesn't help at all. My sangololu board will not connect over the serial port to my computer or raspberry pi running octopi. I cannot get the lcd to turn on. I only mentioned the mega 2560 because I want to eventually hook that up. I can't seem to get the wiring correct on that one either ...

I recently got a Prusa i3 Pro B from you guys, You can see my last posts about missing parts and other stuff not working. I recently tried to power up my printer for a job and its been working great lately, it didnt power up the LCD at all. The light on the sangulolou board is on, and the fans are ...

When I plug anything into the bed slot on the board, NOTHING shows up at all except for the 140/0. this includes when the extruder thermistor and the thermistor attached to the bed are plugged into the bed-slot on the board...

Clearly both thermistors work.... if they both show the correct room ...

yes, it is 16 degrees C where I am, but the bed is not 140... its as cold as the room im in..

So. If I switch the thermistors, and the temp stays the same as before on the extruder and bed.. wouldnt that mean its a bad board/ "B-THERM" port on the board??? The thermistors are working if I switch ...

Sorry, I didnt know you wanted both thermistors plugged in, the last picture i sent was only with the extruder thermistor plugged into the heatbed only, here is a picture of both plugged in but reversed... like you wanted..

Why didn't the heatbed heat up when i switched the thermistors though? shouldn't it have heated up then since it had a working thermistor?

Heres what it looks like:

Thats what I checked the first time... Its normal..

No there is no light that comes on.

Just tested with a multimeter and it's showing resistance/ is good. Not sure what else it could be
