So I have it all wired back up finally im using: RepRap-gen3-firmware-2009-08-05 and the fiveD firmware to test on the two hosts.
It seams that it will not read the thermistor value.
I checked for voltage accross the thermistor input and it read just under 5 volts.
I tried to check the resistance on the 4.7k resistor but its so small and I dont think I got a accurate reading, multimeter did not say 4.7.
I can get the print head to heat up (I dont let it go for long, as i dont know the temp)
Reprap host software says 000 for temperature. If i switch to the makerbot firmware and use Replicator G it just reads 255C.
I soldered up another temperature board and wired it to A6, and attempted to change the code, but i dont know enough about the code to see if it works.
My thermistor reads about 75k ohms in my garage, which i believe is correct.
What should I do next?
