rigid tapping g33.1 isnt working spindle isnt sync was created by fabworx
I just now got around to trying to get this to work. as it is now my mill is running. spindle works with my gear change and my screen is updating with rpm and gear selection as it should. however my I never could figure out how to make the ui tell me that a gear change will be needed for the called for rpm. also at lower speeds my on target light does not stay constantly lit. so I didn't realize I had a real problem till I tried to rigid tap today for the first time. cause up until today my parts have been coming out fine.
a little run down on my equipment. the spindle is a two speed gear driven unit that is also belt feed. does that make sense? it also incorporates a power driven draw bar so putting an encoder directly on the final driven spindle is a no go. I have swapped the v belt system for a timing belt arrangement as to have a positive drive with no slip. well limited slip. I have done this so I could mount my encoder directly on the motor shaft.
so all that being said, here is the spindle section of my hal file. I feel like something has to be wrong with how I have connected things in here or haven't connected things correctly. i would appreciate it if I could get some of the expertise that I know is present here on what I should do or what needs attention. thank you in advance.

The encoder-counter software doesn't know what you have done

That's what I am saying.Are you saying what I'm thinking your saying? In the case where the encoder is not attached to the spindle or geared 1:1 with the spindle don't use the encoder index but rather provide an index directly from the spindle?
