@Phaedrux Thank yo for your reply.
I increased the "H" parameter in the Z-probe definition, as suggested by @o_lampe. This solved my problem.
Thank you again.

Hi forum
I could need help diagnosing a problem with probing.
I am running Duetwifi and the IR probe.
The printer has been running without problems till now, but recently a problem accured.
The probe is working on the first couple of probing positions, but as it moves to a new position it skips the probing and continues to the next position. There is a error message when a probing point is skipped "probe already triggered at start of probing move".
Any help would be greatly appreciated.
Kind Regards
Poul Erik

Thank you @achrn
Your time is much appreciated.
I will change the SSR and see if this solves my issue.

@zapta said in 230v heatbed thermal runaway:

Duet and the SSR, does the bed heats when you turn the printer on? If so, you may have shorted SSR.
Also, does your SSR have a led, indicating the control signal? I so, it will help you identify if the problem is on the duet/firmware side or the SSR.

Thank you @zapta
What might cause the SSR to short?

@gixxerfast said in 230v heatbed thermal runaway:

the input of the SSR, does the LED on the SSR (if there's one) light up ?

HI @gixxerfast The heatbed will turn on even if the bed is not marked as active.
There is no led on the SSR.

Thank you.

Thank you Tony, I really appreciate your time.
The wiring is pretty standard and worked until yesterday.

I suspect you are asking for somthing other than what the image is showing! But what?

Kind Regards

@t3p3tony
i would have to take the printer apart to answer how the it is wired.

@t3p3tony
Yes, it starts heating rightaway.
