Hey folks,
I'm looking for a hint or a solution to change the behaviour when the error "BED_MAXTEMP"occours. Right now it turns the MOSFET off, i would like it to turn off the powersupply.
After my MOSFET (for heating the bed) burned, the power couldn't be turned off anymore and...well it stinks.
Due to this encounter i made a little circuit to cut off the power to my printer.
So far everything works great, after sending the command M81, the PS_ON pin (D12) is turned off and my 24Volt powersupply is beeing cut from the main power.
Unfortunately i haven't found a solution to turn this pin automatically off when the error "MAX_BEDTEMP" occours. Just in case something like this happens again.
