ad595 thermocouple on RADDS which pin (5V input needed)
I am trying to connect a thermocouple to the RADDS via an external thermocouple extension board. ( http://reprap.org/wiki/ExtThermoCouple_1.0) I found some info about some other extension boards and RADDS but they all need less then 3,3 v input. I have an lcd connected, and i am planning in using an extension board so the aux1 will also be taken.
Would it be possible to take the 5v from the aux1 and the ground and signal via the xmin endstop? And so yes could i just tell the firmware to use the xmin endstop?
Or is there a simpler solution?
