M19 and spindle-index-enable issues

(Untested, I am on a train)

Can do something like homing the spindle when turning on the machine? (By running the spindle for a few seconds).
And to control whether the index mark is found after that - if it is not found - an error!

I intend to add spindles to the homing sequence. In fact the whole multi-spindle change was mainly in preparation for that.

I just haven't done it yet.

Bringing back an older thread because there seems to be another issue that people run into with high(er) speed spindles and spindle index / M19. 

Everything seems to work until the spindle is at higher speeds and right after that you call an M19 to orient the spindle. 

Example:

S1000 M3 
M5 
M19 R0  -> Spindle is a 0 degree

S16000 M3
M5
M19 R0 -> Spindle is at 30 degree or another number due to EMI or another reason the spindle encoder count doesn't match a 100% anymore.

I was thinking of writing a component that would wait for spindle off and a low rpm range (1000 - 2000 etc) and then set the spindle-index high again. The spindle would then re-index before it stops and the next time an M19 is called the position should be accurate again?

Thoughts or other ideas?

 

Maybe add homing to the orient comp?
