Using Stall detection as emergency shutdown?
-
Hi!
This weekend, an unfortunate mistake happend to me:
For any reason the BL-Touch clamp broke while homeing... Unfortunately this happend exact at the moment I had no eye on the printer... As I came back, the nozzle had scratched over the whole printbed and was stuck at a bed clamp.So my question:
Is there a chance to use stall detection as emergency shutdown? So if the board detects stall detection (e.g. after a print didn't stick at the printbed and the nozzle crashed into it etc.) the stepper motors should be turned off as well as the heatbed and nozzle?Greetings kuhni

I presume it is just the Z motor that you would want this to apply to?
I can add it to the firmware wish list. The change would be to add option R4 to the M915 command, meaning do an emergency stop.

The circumstance as it happend was the following: Due to the broken Bltouch the bed leveled to high. So x and y moved and the nozzle scratched over the bed. So I think it would also be great for x and Y.
Other problem could be: a print that doesn't stick to the bed and causes a crash of the nozzle.
