@targenaut said in Heat Bed Runs immediately after plugging in Duet.:

@dc42 It does help. I do not view one in thousands as reason for alarm or improvement. I thought it was a rare case as I did try to find similar situations before posting without a lot of luck. Your comment seems to verify that.

Thanks for the assistance and im sure after some time I will get settled about the situation. It was more just me recognizing what i had of value in that room alone and being in a bit of panic about it.

I also still havnt ruled out that it wasnt something I did as this was running perfectly before this.

And, I am in the United States.

You've now been in touch with Duet3D and we've established that your Duet is a version 0.8.5, not a Duet 2. I'm not involved with the Duet 085 because that was a product of Think3Dprint3D, not Duet3D. However, as you are in the USA one option for you would be to ask forum user W3DRK if he can give you a price to mend the board. He is very competent and does Duet 2 repairs for us.
