    I have identical x and y axis (same type of motor, same type of switches) ,same config. With
    G28.2 Y0
    the Y homing works ok, and takes few seconds.
    with
    G28.2 X0
    the X homing works, but the motor runs at very slow speed (1 % of what it should). The homing swithh signal Xmin works ok, I cerified it with multimeter (3.3v when in home-position).
    The configuration of homing is:
    $xsx 0
    $xsv 500
    $xlv 100
    $xlb 50
    $xzb 10
    $ysx 0
    $ysv 500
    $ylv 100
    $ylb 50
    $yzb 10

    You apparently have a very fine thread screw machine of some sort ($_tr=2mm).

    Are you running the machine from CoolTerm?
    Your value of $si=100000ms is very high, could confuse ChiliPeppr which is status driven. More typical is $si=500.

    Does the machine jog appropriately?
    Are you sure machine isn’t binding in x direction?

    Have you tweaked the motor current pots at all?
