Can check content bed.g?



  • Hi,

    I follow do work Bltouch in Duet…

    A- the individual gcode [c]G30 S-1[/c] works
    B- The problems apear when try autocalibrate printer… I have headcrash

    When I send autocalibrate, Duet do the orders content in [c] bed.g[/c]. No?

    Maybe… The error is in [c] bed.g[/c], moreover, my [c] bed.g[/c] is the same when I was installed MINI IR PROBE

    Copy and paste my [c] bed.g[/c], if you can see some error.

    The only important difference, is that G30, have the flag H0.
    A thing that I don't understand is that… When I try autocalibrate, Duet do the orders in [c] bed.g[/c]. No?
    When I try do autocalibrate… First printer homes, and after down nozzle straight and in this point, x0 y, I have the headcrash but the first point in [c] bed.g[/c] is [c] G30 P0 X0.00 Y135.00 Z-99999 H0 [/c]

    Another try I want to do is downgrade firmware. In what firmware is tested Bltouch works?

    Thanks

    You should remove the G31 X0 Y0 line, that was for very old firmware.

    After you home the printer by sending G28, the effector should be close to its maximum height and ni the centre. The web interface should show the position as X=0, Y=0, Z= [height of nozzle above the bed]. Is that what you get?

    Please post your deployprobe.g, retractprobe.g, config.g and homeall.g files.

    I suggest you don't downgrade the firmware, it will complicate matters and make it harder for me to support you.

    PS - in bed.g you should add a M401 command before the first G30 command to deploy the probe, and M402 after the last one to retract it.



  • Hi,

    In [c]bed.g[/c], its necesary redeply BlTouch after each [c]G30[/c]?

    How?

    P.D.; After send content of configuration files in Duet

    deployprobe.g and retractprobe.g must be in the /sys directory, because that is where the firmware looks for them.

    In bed.g, its necesary redeply BlTouch after each G30?

    No. Just use M401 before the first G30, and M402 after the last one.
