If the joint limits where being ignored then the problem would be that
the joint limits were being ignored, not just "no motion".

The way I would debug this is to program one joint at a time.  Get the
base joint to work in world coordinates first.  Figure out what
happens when you give it a possible (x,y,z) location and an impossible
one.  Then giet the next joint going.     Jumping straight to making a
6-DOFarm work is hard.   Get the 1-DOF case to work

My guess without looking is that the software is not finding any
kinematic solutions and therefore not moving.  Either that or it is
finding (literally) an infinite number of solutions and then not
moving.

If the log files are not helping you should try adding more debug
logging in the code


My opinion? I'd run in joint mode and use a more sophisticated motion
planner and do the planning and kinematics there and then sendd EMC
commands in joint space.   But maybe you have a good use case for
doing this inside EMC, perhaps teleoperation where a human does the
planing in real time?
