I have a U0007 with bootloader BOT01.04.... The firmware that will update this receiver is in the update2019-08-27 branch. I have updated my receiver manually, but why isn't RQR12.11_B0032 available...

If you do not switch both hot wires, the elements stay energized and touching them will shock you. You can get a 3 phase SSR and use 2 sets of...

The schematic shows that each element is 120V. It is a bit weird, it is not a balanced load, L1 has 2x the load as L2. Each knob/switch gets a...

A third wire for a case ground is needed. If the controller is using 120v for a pi power supply, then you need a 4th wire for neutral, or a...

In electronics they call it voltage drop. With 2 elements (the elements match) in series, each will drop half the voltage. For 240V, if you measure across one of the...

I think you may be misdirected by the error interpretation. Looking at the MAX31856 datasheet, I do not see a fault classification that would correlate to Shorted Thermocouple. I see...

I had one failure recently: The kiln is on wheels and I rolled it a bit too far away from the controller. The thermocouple wire is the shortest. Another failure...

I am trying to think of what is changing due to heat. Here is a few thoughts. If the kiln is not case grounded, then ground it. It may be,...

I was assuming, not the code. It looks like the MAX31855, throws errors for short to Ground, and short to Vcc. I looked over the project code and it combines...
