would be if someone had a loose or sticky switch at the Index marker.
It would not take many scraped parts to figure that out though.
I didn't know what to think when you said "I made the index sensing
edge-triggered on my boards". Do you sell boards, make your own, or
both? If you don't mind me knowing.
I just noticed the Pico-Systems and googled it. Hi neighbor.
I am interested in EMC related interface products you may have, for
the future. A new email for EKCO coming.
Thanks again
Don
