Command 'quit' not found, did you mean:

command 'luit' from deb x11-utils
command 'quilt' from deb quilt
command 'quiz' from deb bsdgames
command 'qgit' from deb qgit
command 'quot' from deb quota

Try: sudo apt install <deb name>

mike@cnc:~$

Did you have Linuxcnc running whilst trying this ?

No I didn't, it won't run unless I delete the HALFILE xhc-whb04b-6.hal
Should I delete that and have Linuxcnc running and run those commands again?

No.
Actually reboot and run those commands again.
But type them in one at a time rather than copy & paste them all at once.

Ok it would appear that the user comp is loading.

Now rename xhc-whb04b-6.hal to MyPendant.hal and change the entry in your /home/mike/linuxcnc/configs/my_LinuxCNC_machine/my_LinuxCNC_machine.ini from xhc-whb04b-6.hal to MyPendant.hal

Reboot and try to start Linuxcnc.
