Was this working up till now? a new program? does the spindle come on? can
you post the g-code you're trying to run? is this barfeed work? ID or OD
chucking? I assume spindle comes on and tool rapids to approach position and
just sits there with coolant on, and looking at position page nothing is
moving and it shows proper "distance to go"? Does any other program run
properly? Can you MDI a cut? Can you see ACTUAL spindle speed on your
Help us help you,
Yes, and if you have more than one spindle, like in a lathe with a
counterspindle, it has to be paying attention to the correct one.
That is selectable on all the machines that we have that have more
than one spindle. Feeds per revolution can be based off of whatever
spindle or live tool you want, but you have to know and specify.
When the program is running, if you are in the "Program" screen, and
in the "Check" screen with the distances to go and such, you should
see a S act. or whatever that shows the actual spindle RPM. I could
be wrong, but I think the display is based on whatever spindle is
selected. At least I think that's the case. If the spindle you are
trying to cut on is actually running, and that S act. reads 0 RPM,
then something is wrong anyway.

Check the encoder belt on your spindle if it is broke then you have no
pulse code for the feed. Should be mounted directly to the spindle. It
is also used to thread. Some machines will display the spindle speed
based on the comanded motor speed instead of the actual rotation speed
of the chuck.
