I have a delta Rostock, (Arduino MEGA2650 and ramps 1.4) and I am trying to run the extruder with a MAX6675 thermocouple via SPI interface. I know my pin configuration is correct, because everything works with an older version of Marlin firmware. With the Repetier firmware ver. 91, I get a temperature reading, but it will not update.
As Repetier seems to be written in C++ and uses non standard arduino libraries, I am at a loss as to what to do. I have tried changing SPI speed and delays between the reads and writes, but this is really out of my league,
I have seen some other posts with a similar problem, but no solutions have been posted.
Is anyone out there using Repetier firmware and successfully using the MAX6675?
Thanks in advance....
