I bought a CNC lathe, model KND, K1Ti (identical with FANUC CNC systems).
The chuck of the machine looks locked, it seems I cannot open
it or close it manually as shown in the attached photo.
In my machine panel, there is no control key to clamp/unclamp
the chuck. So I think I should open/close it by a program.
I run the following program:
M11 // chuck unclamped
G04 U3 // dwell for 3 seconds
M10 // chuck clamped
G04 U3 // dwell for 3 seconds
...
and nothing happened. The chuck does not move.
Although I hear a sound of a relay that dilever 24v to something when I run M11 and
there is another relay that also dilever 24v when I run M10.
Does that mean there is a 24v motor that controls the chuck? It looks so.
What could be the problem? Is it a wiring problem or software problem?
Should I check the cables? What is your suggestions?
