I knew if I asked - the answer would be simple. I just changed to a real MPG (Fanuc) this morning. I only need one mpg with touchy. I had three pulse generators connected to three software encoders. They work but not very good. They move better one direction than the other. If you spin the pulse generators the exact right speed the count works good both directions.

Chris > thanks Stuart -- The value of goods are expressed in money, while the value of money is expressed in goods. Money and goods are clearly not the same things, but are exactly opposite things. Goods are wealth which you have, while money is a claim on wealth which you do not have. Goods are an asset; Money is a debt. If goods are wealth; money is clearly not wealth, it is negative wealth, maybe even anti-wealth. – Quigley, Tragedy and Hope, pg. 44 (emphasis added) ------------------------------------------------------------------------------ Join us December 9, 2009 for the Red Hat Virtual Experience, a free event focused on virtualization and cloud computing.
