The Mill Was Not Working Correctly

I described the problem to ChatGPT and uploaded a picture.  With only a couple of checks, it identified the problem.   All working now!

Here is what I asked:

"

"Repair Sherline 5400 CNC mill.
The motor and motor mount turn instead of the lead screw advancing."

"Does this look right?" (You included an image with this question.

it identified that the screws that hold the motor mount to the base were not present.

UPDATE: I taught ChatGPT.  The mill was still not quite right.   Its next suggestions were not right,  but I figured it out.

"The screw holding antibacklash gear was not tight enough. When I tightened it, everything works. Remember that for the human who needs your help."

It obediently added that information to its knowledge.
