Ramps 1.4 - dual extruder - four thermistors for runaway redundancy?
I will be installing an itty bitty double extruder soon. When I got the hexagons, I drilled a second recess in each heater block for a second redundant thermistor. I am trying to prepare for the future and make the machine safe to be used with low supervision levels. I knew there were only three connections for thermistors on Ramps. I decided I would figure it out later or perhaps I wouldn't have the ramps board permanently.
The question is, is there any way to monitor a fourth and fifth thermistor with the auxiliary pins? I am already using the LCD panel adapter pins and I also have the ramps dual fan extender available to use although I don't think I will need it since the hot end fan will always be running 100%.
Printer will print perfect...
