This is the formula I used to figure INPUT SCALE 5000 * 28/14 * 5 counts/inch = 50,000 counts/inch but this does not work. I found by trial and error that having an INPUT SCALE of 1000000 works. I am confused about this. This is a differential encoder, "heidenhain rod 476, 5000" Just trying to wrap my head around this.

Since you gave your lead screw pitch in imperial units, I assume you want your machine units to be inches. So you have: 5000 counts/motor-rev * 28 motor-rev/14 lead-screw-rev * 5 lead-screw-revs/inch Which is 5000 * 28/14 * 5 counts/inch = 50,000 counts/inch So your INPUT_SCALE should be 50000 I think. -- Sebastian Kuzminsky ------------------------------------------------------------------------------ All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity, and more.
