Problem with emergency buttom

[qlfecv]

When I use this setting for an emergency button, the board locks when it is working.

Is correct it?

M950 J1 C"!^exp.heater4" ; Stop buttom pullup active low
M581 P1 T0 C0 ; Emergency stop on trigger anytime

Firmware version? Send M115 to check.

How you format the command will depend on your firmware version.
