Hello,

I´m thinking in electronic to do my new printer. I have experience with megatroncis but now I want change to ramps. But my problem is that I like to use dual extruder with two thermocouple. Me doubt is where I connect the second thermocouple board in ramps. Other problem is the use of fan, can I use fan for piece with dual extruder and hot bed?

Thanks for help

you can start reading about ramps from here:
[reprap.org]

Note: RAMPS doesn't read thermocouples. you must use a thermistor !!!

Second Extruder Sensor gets plugged into T2

It's all right there in the wiring information on the RAMPS 1.4 wiki
