imitation

I tried PID tuning on my Mendel today. It's a Prusa Mendel with Ramps1.4 and a 100k NTC-based hotend (reprap-fab). After hacking in the pin configuration for the Ramps and setting the Thermistor, i started the tuning process. My workshop is pretty cold atm, and i regularly run into MINTEMP at the start of a print, so i didn't think much about the initial "some value is too high" error, which went away after heating up the hotend a bit. So when the tuning started, the hotend did heat up, but it reported the maximum raw temperature as 988, and the current temperature was dropping - I guess the tuning process ignores any thermistor/thermocouple setup made and just looks at the raw values. However, for an NTC this doesn't work. At all. I guess i'll have to set up PID the hard way then. -Tom
