Robot 5 DOF Question

I know you can drive 5 axis mills in LinuxCNC

Can I build a 5-DOF robot with 5 axis kinematics, or does it have to be a 6 axis kin with one dummy axis (some how)?

If 6 axis is easier or required, what is the simplist way to build that in?

I think that LinuxCNC has some robot sims included with Vismach visualization, and pretty sure one of those was 5 DOF.
Been to long ...

No. A 5-axis machine kinematic consists of 3 linear cartesian joints X,Y,Z and two rotary joints. A 5 DOF serial manipulator comes with 5 rotary joints.
I'm not aware of a 5 DOF robot simulation config in linuxcnc but I may well be looking in the wrong place. There is 'scorbot-kins.c' in the 'src/emc/kinematics' folder that seems to be for a 5 DOF 'Scorbot ER3'.
For 6 axis there is the generic 'genserkins' and the 'pumakins' kinematic.

If somebody finds others please let me know.

Was there also "scarakins" or similar?
I noticed lately the config picker has changed and stuff is added and missing from it, hence i was not sure what is there anymore.
Thank you.
