Minion down
Hi, with my Minion I am still a apprentice. Yesterday in the evening I get the fault "verify heater bed ......". Bed stays cold. Today I opened the box (not powered). I disconnected the heatbed wires and measures the electric resistance. It started (my meter tells me MOhm) at 28 and go down to no connect (o/l) during 5 to 8 seconds. Then it start again at 28 (roundabout) and counts back.
Next I give power to the box. There was no power on the clamps. I set the temp to 50 degrees in mainsail and I get 22 volt.
So I thing the Bigtreetech octopus is working right?
Any advice?

Sounds like your heater wires are broken
I doubt the traces in the pad died, but it's possible.

Thanks, a new silicone mat is ordered at AE.
When I change the mat, how do I proces withe the cable drag chain. can I open the single link, can I open it link by link or do I have to pull through the cable through the complete chain??
The minion does not have drag chains. I don't know which drag chain you have or what mods you're using, but that's likely part of the reason your heater wires died.
drag chains can be brutal on wires not specifically made for it.

Mine have dragchains. I bought it second hand. But I thought in the same way about.
