Ran a program to test the M19 command
Spindle started spinning at ~2000rpm
Nothing else happened, so I pressed Feed Hold
Spindle did not stop when I hit Feed Hold
Spindle did not stop when I hit the power off button
Spindle continued to spin when I powered the machine back on
Spindle did not stop when I hit the Manual Stop Spindle button
I then typed in S100, turned on spindle clockwise and then the spindle downshifted to 100rpm. I then pressed spindle stop, and it stopped.
Background:
Old mill I have self-taught myself on. I don't know how to do some of the things on it and I am the most knowledgeable person on it at our shop. The mill has a horizontal and vertical spindle, however the horizontal spindle blank is not fully in there and I have no idea how to change between the horizontal and vertical. I have disabled the tool changer as it would continually say TC NOT IN BASE POSITION and nobody knows how to get that to work either. The Horizontal/Vertical switch results in no command.
Reading the manuals again I came across some interesting lines. M18 Search for Tool (for automatic tool change) and M19 Spindle orientation (for automatic tool change). I tried typing in M19, no luck, so I wrote a small program as follows:
N10 M3 S100
N20 M19
N30 M30
I ran it and saw something I thought I would never see. The spindle spinning when the red Power Off button was hit. (Note: The E-Stop button has been looked into, but does not work. The E-Stop is an AC circuit that somehow gets power from somewhere and will sometimes continue to stay on even when hit. When I picked up the mill someone had made a fused jumper across the circuit so the buttons do nothing. I had always assumed that Power Off would stop any servo in its tracks.)
Questions:
1. WTF is M19? How is it used? Do I activate it to change the spindle orientation? What is it doing?
2. How does one change the spindle orientation?
3. How could hitting the red square Power Off button not turn off the spindle? What am I missing? This was truly scary.
