I was running a production run of parts, drilling holes accurate to .00001" position, and suddenly I noticed that Z was not returning to 0. Was something else broken? It appears that trying to center drill at 0.5 ipm was confusing it about where Z was? At 0.2 IPM, no problem. Perhaps switching to carbide center drill bits would be good.
UPDATE: Even at 0.1 IPM, Z was getting shifted. I have changed to the glacially slow 0.5 IPM, and increased drill depth to 0.5 to compensate for possible Z errors on start.
