If the limit switches are shared, then the first axis must be moved off the limit switch before the 2nd axis can search for home, then again for the 3rd axis. Just setting the home position to a large enough non-zero value should accomplish that.

There is a bit of a glitch, at least on some encoder counter schemes, when the encoder count is suddenly set to zero by the index pulse. It is pretty small, as the driver masks most of the discontinuity. Missed you at the CNC Workshop!
