nope!
no need to...
the thermocouple outputs a linear value... meaning its super easy to convert the analog reading to a celsius value. theres more information on the doc page: [
make.rrrf.org]
here's the code:
int raw = analogRead(0);
int celsius = ( 5.0 * raw * 100.0) / 1024.0;
the GCode firmware already supports this, and it would be fairly easy to add it to the SNAP v1 stuff. it will definitely be in SNAP v2.
