AD595

lorenzinglorenzing
in Repetier-Firmware
Hi,
I have an anycubic trigorilla (ramps 1.4) and I want to use a termocouple ad595 circuit on T0 pin. Unfortunately, if imposed it in the firmware the board don't detect anything. I tried also on T2 but I have the same problem. What can cause this problem?

Configuration.h: here
Full firmware: here

Thank you in advance for your help.
Lorenzo

                            Thermocouples do not work at the T0-2 pins of RAMPS as these use a voltage divide with 4.7K meant for thermistors.
    You need to connect the output to a free analog pin on one of the extension ports and set the analog pin number (not digital one!) as pin.

                            Unfortunately on this board there are no free other analog pins. and 'the problrma can be corrected by software? I could fix the AD595 multipliers?

                            I have removed the resistance and it works perfectly. 

     Thanks so much

                            Ok, nothing I would have adviced but removing resistor makes it a plain analog input so yes, that does it.
