No chamber heater found
Think I am missing something or just being stupid...
Added the Variable and two macros (nothing in them yet but might add something later) in the printer.cfg
Then also added the sensor and heater pin section with the correct pins into the printer.cfg
Save and restart. But still cannot execute the Chamber PID.... What am I missing?

This is what I followed.
No you didn't, because your configuration isn't anything like the example 🙂
You didn't get this from the documentation
Oh wait, you did, it's just not what you want
you want an actual heater if you want to PID control something.
you can't PID an output pin, there's no feedback.
you want a
[heater]I have a external PTC heater/fan connected via a SSR to pin PC13 for control
That's not external. External means external (temperature) controller.
PID is a control loop mechanism.
You can't control something that is controlled externally
To further clarify, an SSR isn't a controller, it's a relay.
True.... Thats why I said I was doing something stupid!!
Haha it's all good, could be futher clarified in the docs tbh
Added a bit of clarification in the titles.
