In our CCCZH laboratory we are using the R2C2-Electronics from BitBox<\/a> now.

\nFirst run. Uh! Oh! It’s smoking.
\nWe had to drill and poke the PLA out of the PEEK.
\nWhat had happened?
\nWell. Math happened \ud83d\ude42

\nThe Bitboxers obviously dimensioned their serial resistor for another thermistor.
\nWolfgang is using the B57560G104F<\/a> in his hotend.
\nSo with a 10k\u03a9 resistor in series the voltage on the ADC will look like that:

\nWhile basically it should look like that (with R1=500\u03a9):
\n\"\"
\nOr in short: Let’s get the soldering iron again >.<
\nThe C-Code will then look like that:
