Hi everyone,

I have had a problem since I touched both extrusor led wires. It did a short-circuit, but the smoothieboard reset and turned on again and is all fine, EXCEPT, the temperature indicators (extrusor and bed at the same time) are wrong, as seen in the picture.

I tried to set temperature through the CPU, Simplify3D driver, and the resistance rise temperature very well but the display still showing 22 Cº and has no control of the temp. Of course, the bed temp values are complete anormal. 

It is possible to check something, before dissasemble the board from the printer?

Thank you very much.
Maurizio.

Really sorry to say, your thermistor inputs are dead, unfortunately there is no way to fix them, as the issue is inside the microcontroller itself.

Good Afternoon, and sorry for another question

Is it possible to connect and configure the another 2 thermistor inputs remaining by software, to make it work? There are 4 inputs in this board.

And also, what is the last version of this board (board.png), If I have to purchase a new one? I dont know which is compatible with this one.

Thanks very much!

You can try, but it's unlikely to work: if TH1 and TH2 are burnt, it's very likely the whole internal ADC group is burnt.

There are 4 inputs in this board.

And also, what is the last version of this board (board.png), If I have to purchase a new one? I dont know which is compatible with this one.

Latest version is 1.1 If you can't find stock you can email me and I'll try to help find some.

Thanks very much!

Arthur, You're right,

I tried to configure the pins 0.25 and 0.26 but doesn't work :(. I'm going to think in another proyect with this board, because the other inputs and ouputs are fine.


I'll Email you for the board. 

Thank you very much. Regards.
