Thanks @RichRickett, That’s what I was thinking too, not worth blowing up the new controller 🙂 The support team has been very helpful with me too! Will definitely be more careful from now on! ---

Exactly my experience too. How did you order the replacement multi connection controller board? ---

You talk to support. They’ll send you just about anything. ---

Same thing happened to me yesterday. I have the enclosure and I was going from 10W laser to 3D print module. I did exactly what others have said and due to the poor connector design there was significant smoke and pops when I applied power. ---

Ya, super annoying (and costly). I don’t know why they couldn’t put the connectors all in the same orientation. I put a big white arrow on the module connector tab so I don’t ever forget. ---

It’s all very well having a locking tab that also serves as a visual clue to its orientation, but if it’s possible to get it the wrong way around then it’s virtually useless. ---

Problem is that after going home, the toolhead is too close to the top of the enclosure to see the connector. It’s much better now I got the quick swap kit, which leaves the tool in roughly the middle. Btw - I HIGHLY recommend the quick swap kit.
