    I keep getting a soft max and min limit after homing x and stops the homing all process, after homing it gives "Exceeded POSITIVE soft limit (4.80000) on joint 0" i can neither move x or y axis, can move z axis, I can home y axis, but then I cant move z axis after that.I have the axis version of linuxcnc 2.9.0 on plasma KDE desktop.

Looks like your min and max limits on X and Y (and joints 0,1) are reversed.

Yes, because whenever I flip it the bed homes in the opposite direction, maybe I'm doing something wrong, but that was the solution i found until now

You need to change the home search direction for that.

it does not change, it still homes in the same direction. only flipping the positive and negative in the table length changes the direction.

If the homing direct does not change, then it's likely the you did not
change the correct ini constant (or perhaps there is another error in
the ini file homing constants or perhaps home switch operation)

I don't think you can eliminate the soft limits issue unless you get the
MIN_LIMIT and MAX_LIMIT setup properly (MIN_LIMIT < MAX_LIMIT)

It may also be the you have the hardware directions reversed, this you can
fix by inverting the direction pin or changing the sign of the joint SCALE
ini constant. (say 4000 to -4000)
