Do I have this same problem? Or Am I fighting something else?

My Z axis just stops completely, 100% not moving, or making a sound, or resisting me twisting the knob. I was getting it when I was jumping around with my LCD screen, but I just did my first cut of some foam, and it did a few minutes, maybe, and it just stopped moving the Z axis.

I used estlcam to make the gcode. I set the G00 to G01 in the settings as suggested. I have a 3mm/s plunge rate. The LCD panel says my Vzmax is 8.

The strangest thing is that I also don’t know what I did to fix this before. I power cycled, waited, etc. This time, the Z didn’t come back. I swapped the cables so the Z motor was being driven by the X driver, and it moved just fine. The driver is cold to the touch. Maybe it finally pooped on me.

Here’s a quick sample of the gcode, I only see Z with an F180, which is 3mm/s, I think.:
