[Emc-users] missing tooth index questions..

I have a optical encoder from a mouse running on an emco encoder wheel (100 holes). I cut out the metal between 2 holes. I think that would be considered one missing tooth... I have the encoder scale set to 100 and the missing tooth set to 1 I have a little comp that sets the index enable to

Lol.. I remember Chris R was working on rigid tapping at one of the fests in galesberg.. He was using the mazak which had been converted to linuxcnc.. (I think it had been worked on over a couple fests. ). Anyway - it didn't seem to be tracking the correct pitch.. (Tapping in plastic).
