Heating start directly with start of printer
Hi guys,
after i solved the issue with the jumpers with your help. I got now the second problem.
First time started the printer and it begin directly to heat up the noozle and the bed (ssr red light is on)
Also after connecting to the pi it is not stopping with heating. I attached a screenshot of the temperatures and my log. I dont understand why the printer starts the heating up. Found out that it could be a problem with the thermistors but both are showing and changing the values.
Hope you guys can help me out again.

I found out that i need to deactivate the following command to connect the mcu.

If not set on False i am not able to connect
That is a red herring (meaning it has nothing to do with your issue).
How have you wired up your SSR?

Both heater (bed and extruder are heating up at start)

All the green leds are on after starting the board.

This is how i connected the ssr

The neutral goes into the bed heater to the ssr. And L is connected directly to the psu
The blue cable in the ssr need to be brown. But the wiring seems to be ok.
Just making sure, this is not one of the boards that got shorted, right?

Nope thats the third board
If someone has the same problem here is my issue.
The mcu showed a temperature of 178°C directly after starting. If you change manually max temp to 200 you can use the board. But i decided to send it back and get a new one. Dont know why i got the issue. I think something was wrong with the board.
disconnect the power going to the ssr (remove AC power that can be applied... and see if the temp readings are as before. could be your probe is simply not configured properly
Have you tried/executed as bed temp PID calibration with success?
