This is a simple test setup  for a 50 count optical homemade encoder. In quadrature 4 x 50 = 200 ppr. One rev. = .200 with 5 threads per inch (TPI). This Disk is 4 1/4" in Diameter with 50 slots for 1 thousand (.001) of an inch resolution on the DRO. This could also be used for Manual Pulse Generator (MPG), by adding a detent for incrementing.
