Z-movement stopped working in dual Y XYYZ 4-joint mode system

Hi, I'm in the process of putting together plasma CNC. Now I'm stuck on the following issue:

Before I've changed from 3-joint I could move Z-axis (PgUp/PgDown or +/-) buttons on the screen.

I haven't changed pins for the motor DIR and PUL, when I test it via stepconf it does work.

I have changed HAL as it was required for the 4th joint.

When LinuxCNC starts the config from fresh it displays joints as numbers from 0 to 3. Before execution of "HOME ALL" I can select joint 3 (z-axis) and using +/- buttons on the screen I can feel the motor movement (but is tiny not as per expected move). After "HOME ALL" when Linux CNC is in axis mode the move of z by +/- on the screen does not move motor at all.

My setup:
x-axis on joint 0 (min and home on single input)
y-axis on joint 1 and joint 2 (min and home as one on each joint)
z-axis on joint 3 (no sensors)

I'm attaching my conf and INI

I'm a complete newbie and do not know where to start.

Please help!

Thank you very much for your help!

I have changed MAX_LIMIT for AXIS and JOINT to 120.0 (mm) and it now allows me to move z-axis.I have made one more change. The movement was reversed PgUp was moving the axis down and PgDown was moving axis up. I've changed the scale to "-" value and now I can move it as expected.

Now time to move to the integration of plasma and the torch height controller.
