Hi Peter; If I write a hal thing that changes the value pushed into the encoder's scale input, how much of a time lag might there be to make it effective?
The scenario is this: I have ordered a 1000 line Omron encoder, which I intend to couple to the rear of the spindle motor shaft, feeding its a/b into the encoder in a 5i25. But the index signal from the new encoder will not be used, remaining with the index in my shop made encoder, and therefore at a known location of the spindles rotation, with the desired end result being a different scale factor according to the gear setting in effect at the instant. So given a couple turns of the spindle to allow the encoder to get re-synced with the new scale setting I ought to be able to do rigid tapping in either gear. Like 4-40's in high gear, and as much as 8mm in low gear. Obviously I don't envision changing this in mid-tap. Other than that potential screw-up on the part of the operator, me, do you see any problems with such a setup?
