No thermal runaway protection #30

I flashed my x2 with BLTouch-3x3-HS-H32.bin but when I tested it, does not have thermal runaway protection working for the hot end.

The new firmware does show the new screen, but when I disconnect the hot end thermistor it just continues to heat up infinitely. This is a fire hazard unfortunately.

I tested using "Aquila H32 BLtouch Firmware V5.8.2" from aquila's site and it does have thermal runaway protection. It's not very good. I had to touch a screwdriver to the end of the thermistor to deliberately make it cool down enough to trigger the shutdown signal but it does respond to the error condition. I tried several times to get the BLTouch-3x3-HS-H32.bin to trigger shutdown by cooling the thermistor tip while heating the hot end but it never triggers no matter what.
