That's bad; it could be dangerous because you don't have control over the hot end temperature. Take a look at the tabs on the power MOSFET transistors adjacent to the heated bed and hot end heater connectors. If the tabs are touching each other, bend the transistors forward and back so they don't touch. Then see if the hot end stops heating all on its own. If you have made any changes to the wiring, review exactly what you have done. One side of the heater circuit is permanently connected to +12V; the other side is switched to ground through the MOSFET power transistor. If, somehow, the wire that is supposed to get switched to ground under control of the MOSFET is instead directly connected to ground somehow, then you'll get that uncontrolled heating.

I'll check that but it seems to happen after using curator but not matter hackers control

No idea what curator is or where it runs (too common a name to easily google), but is it a separate board that powers up with the Simple Metal? Is it software that runs in the background on your PC, or was running when your SM was turned on?

Let me get this straight: you are apparently saying that:
Scenario A:
1) You run your printer under "curator" (Cura?) control.
2) You turn off your printer.
3) You turn on the printer and do nothing else, but find your hot end is heating up. ("Doing nothing else" includes you have NOT connected "curator" or any other computer software; the printer is doing this totally on its own.)

Scenario B:
1) You run your printer under MatterHacker control.
2) You turn off your printer.
3) You turn on the printer and do nothing else - and find your hot end is NOT heating up.

Basically, this seems impossible to me, with only one possible exception. The printer totally loses all memory of the state it was in when you power-down. When it boots up, it does not turn on any motors, fans, or heaters. The exception would be if you have an SD card in the slot. I've never worked with SD cards, but maybe when you turn on the printer it starts to run the program (G-Code) that's in the SD card.
