If your screw is .2" pitch, then maybe there are two index pulses / rev? Or is this a linear encoder?
If it was just off by ~ .1" with no accuracy to it, then it is some other problem. EMC2 shouldn't particularly care whether the machine is homed for the first time since starting EMC, or rehoming. It should behave the same way, and be as reliable (or un-reliable) first time or on a rehome. If it really DOES make a difference, that starts to sound like a problem in the HAL driver. Without enough tests, you might be throwing in a red herring on the first time vs. rehome thing.
