Anet A8 BLTouch and Bed heater problems

  • config.g

    I am setting up a Duet 2 Wifi on my Anet A8 and just updated the firmware to the most recent version.

    On when I select Firmware version: 3.0 or later:
    on the page I/O Mapping, under Z-Probe the Pin "PWM Control Channel (BLTouch only)" defaults to "(not assigned)"; should I change this, and if so to what?
    on the page "Endstops" the BLTouch option is no longer available;

    Also, when running the "Check Heater Functionality" test in setup, the bed heater rises about 2-3 degrees above ambient, then generates the following error message and stops:
    Error: Heating fault on heater 0, temperature rising much more slowly than the expected 1.8°C/sec
    That expected rate seems very unrealistic to me, using my stock board it would typically take at least 5 minutes to reach 70C from ambient which is closer to 0.1-0.2C per second.

    How can I fix this?
