Axis stopped moving

I mean check the voltage on the 7I96S  X,Y,Z DIR  pins
When you jog back and forth (relative to ground)

However, I do a lot of simulations before manufacturing a first part. I realized this morning at my desktop I was launching LinuxCNC simulation instead of my LinuxCNC configured profile when axes were overtraveling expected limits. I was probably use to where the configured profile icon was before it was repositioned on the desktop too. The configured profile, commanded spindle and axis movement is operable now. Pardon me for mistaken the sim launch for the config launch and any inconvience.

Sometimes, I might overlook somethings on my portable monitor including the screen (profile) title.

No problem, glad that you are back up and running.
