Floating counter positioning

[Mrwatson 0]

Hi I`m about to post my first one so Help me God.. FX1s 30mr Spray Gun moves along a Table need to outputs Yo Y1 ... using and chainging different areas of the table all the time.. How can I teach or preset a counter to move from point a to point b and then on the next task go from point b to point c ect.. by using a push button set point , then move the gun to stop position preset the 2 positions and start the gun to move back and forward without setting a k number on the counter every single time...So the Up/Dn counter will hovering from thouse points until such a time I do stop It. I`m using a incremental encoder to reference the postions.. opening and closing Y0 or Y1 on either direction.. Cheers I hope I`m clear enogh.. Floating or Teaching positioning

Maybe take the reading off the high speed pulse input and move it to a register when you teach it. Then compare against the register.
