    Anyone used it? Seems great when you need the occasional start hole on your wire edm.

    So, we have started experimenting with the BSA feature on a new part.

    We get a slot that is .010 at the top, and .0095 at the bottom.

    Would I set the BSA offset to .00025 or .0005?

    Every part needs to be probed for center and that takes extra time because T91 waits for the tank to drain, but the tank is already drained.
