    Hi,

    Everytime that I power the arduino, the grbl goes in alarm state, anybody has any idea what could be causing that?

    Here is my $$
    >>> $$
    $0=10
    $1=255
    $2=0
    $3=6
    $4=1
    $5=1
    $6=0
    $10=3
    $11=0.020
    $12=0.002
    $13=0
    $20=1
    $21=0
    $22=1
    $23=0
    $24=1000.000
    $25=7000.000
    $26=25
    $27=8.000
    $30=1000
    $31=0
    $32=0
    $100=106.667
    $101=106.667
    $102=800.000
    $110=3000.000
    $111=3000.000
    $112=2000.000
    $120=500.000
    $121=500.000
    $122=500.000
    $130=540.000
    $131=485.000
    $132=30.000
    ok

    The first message that shows in the verbose and goes in alarm mode is:
    [verbose]GrblFeedbackMessage{message='[GC:G0 G54 G17 G21 G90 G94 M5 M9 T0 F0 S0]', distanceMode='G90', units='G21'}
    [GC:G0 G54 G17 G21 G90 G94 M5 M9 T0 F0 S0]

    $25=7000.000 - The limit you put on the axis is 2/3000 - Lower this to a 1000. That might help.


    $102=800.000 - This seems very high. Are you sure this is correct?

    See documentation at gnea/grbl (direct link to the parameter) You have $22 - Homing Cycle, enabled. If you have it enabled, Grbl will go into ALARM mode on startup to force you to perform the homing cycle so it knows where it is. Disable it by sending $22=0
