Error on config-override.g



  • Hi all,

    Sorry for my English, I have the following problem after updating the firmware 3.1.1. If I don't have a config-override.g and I execute the command M500 it generates the following file:

    M307 H0 A340.0 C140.0 D5.5 S1.00 V0.0 B1
    M307 H1 A340.0 C140.0 D5.5 S1.00 V0.0 B0
    ........

    But, when i try to heat the bed I get the following error:

    Error heater 0 fault temperature rising much more slowly than the expected 1.7°c/sec

    However with firmware 2.5 the M500 command generated the following file:

    M307 H0 A90.0 C700.0 D10.0 S1.00 V0.0 B1
    M307 H1 A340.0 C140.0 D5.5 S1.00 V0.0 B0
    .........

    and I have no problem heating the bed.

    What am I doing wrong?

    The bed is in BANGBANG mode.
    Thanks

    PID tune the bed and save the results.



  • @Phaedrux but i need the bed in BANGBANG. If i run autotune this configured the bed in PID, or after auto-tuning, should I change B0 to B1?

    Why do you need it in bang bang?



  • @Phaedrux I am not using external mosfet as I am waiting for the replacement. Using PID without any external mosfet could bring inconvenience to the board.
    Likewise, the question is whether what the M500 command does with firmware 3.1.1 is correct.
    Currently I solve it by copying the line:

    M307 H0 A90.0 C700.0 D10.0 S1.00 V0.0 B1

    over

    M307 H0 A340.0 C140.0 D5.5 S1.00 V0.0 B1

    Thanks.
