The basic functionality of setting the temperature is available, but the problem was about which method should be used for setting the temperature. Now it’s done via a shell script setting a pin, which is connected to a PID which controls the temperature. This problem is similar to the THC function required for plasma cutting. We do it this way. I’ll have a look at your config files. Is it the dallur-advanced config?
