Firmware, watchdog to prevent overheating etc

Hi,

is there any function in the firmware for some sort of timeout.
For example, if it haven't moved any motors for like 5 minutes, that it power down the heatbed and hotend.

I had an issue last weekend with my printer stopping mid print, just stopped, nothing more happened, fortunately I was there and able to manually stop it (turning of heatbed and hotend).

I have googled around a little bit but haven't found anything about it. IMHO it would be a great security wise improvement if this kind of function existed in the firmware.

(Regarding last weeks issue I haven't analyzed the gcode, could be that it was just broken..)

It is most likely that the GCode file was incomplete (copies before it was fully saved, SD Card removed without Windows "Safe Removal" etc.

There is nothing in the firmware to shut down in this circumstance as far as I know, and the need for it is very infrequent, so I doubt this will be implemented any time soon.

Anders,

did the printer controller crash, or did the print just stop? If the printer just stopped printing, then it is really likely a problem of the G-Code.

The firmware has a thermal runaway feature to guard you against broken temperature sensors.
