So far so good – most of the stuff is done. Currently I’m tuning PID usage, and what’s left is traversing program in time – but that’s easy.

To tune PID parameters and test it, you can use simple halogen light bulb (or car light bulb) connected with thermocouple. This is a good heat source to around 100C and it’s easy to see when it’s working 🙂

You just have to switch SSR to DC-DC one (for kiln you probably will use DC-AC). For easy testing I’ve prepared “Quick program” in LCD menu – where you can set one program step. Provide desire temperature, time and dwell – and you can run it.
