dual-Y machine bolang cnc

For dual-Y machines, if you do not need gantry auto-squaring during homing,

you can use the controller’s default lower-controller firmware,

then connect the pulse/direction signals of the two Y-axis drivers in parallel to the controller’s Y-axis terminals,

in addition, we also provide two extra firmware versions,

for the two firmware versions above, Y2 is used for the original B-axis pulse/direction and limit signal input,

if you use the firmware with gantry auto-squaring disabled, the Y2 limit switch does not need to be connected,
