Emergency Stop Firmware 3.0

  • I have a little bit trouble with my Emergency Stop Button.
    So I use the Firmware Version 3.
    The wire I have take on Pin "e2stop" and grd.

    in my config i have take the code
    M581 P"e2_stop" T0 C0

    if i write M582 T2 in the console i take Nothink back.

    what´s the prob.

    i would later a custom scipt to leave the current possition and lower Z

    Please upgrade to release 3.01-RC4 and check whether the problem still occurs. The code to handle triggers has been largely rewritten since version 3.0. Note, the M581 syntax has been changed.

  • 🙂 I make tomorrow the Upgrade.
    Thx 4 the help.

    The BL-Touch config are the Same.

  • @CupaCabra If your were on RC2 or later, (and so if you upgrade to RC4) you first need to create an input pin using M950 with the J parameter,


    then use the P parameter to refer to this pin in your M581 command


  • For the bltouch make sure you add ^ (turn on pullup) to the pin name, it is off since rc2 IIRC. Might be required for the STOP too if you are just going to use that pin and GND.

  • Hello, Now I have install the new Firmware 3.01 RC4.
    But the config don’t won’t Trigger or make everything.

    M950 J1 C“e2stop“
    M581 P0:3 S1 T2 C1

    The GCode M582 T2 return nothing.

  • Now I read in the Doku. the right name of e2stop are exp.e2stop

    Are the right code
    M950 J1 C"^exp.e2stop”
    M581 P0:3 S1 T0 C0
