It will come up with a new guess of spindle speed next time it sees an index, and the position-interpolated value will then increment at that rate. What is the drive system on your headstock? If there are teeth on a gear or pulley you can probably use them as a rudimentary encoder (if you can spare a pin, preferably two) -- atp "Torque wrenches are for the obedience of fools and the guidance of wise men" ------------------------------------------------------------------------------ Benefiting from Server Virtualization: Beyond Initial Workload Consolidation -- Increasing the use of server virtualization is a top priority.Virtualization can reduce costs, simplify management, and improve application availability and disaster protection.
