I can envisage a HAL component that has parameters X0, Y0, Z0, X1, Y1,
Z1 and SequenceNo.
Outputs would be Pos-X, Pos-Y, PosZ, at-home, input would be current-sequence

Just wire them up to a few stepgens each, and sequence them with
ladder. (or a simple hal component that only increments when all
inputs are "at-home" linked to the current-sequence pins.

More complexity would clearly be necessary once it had absorbed more
than a few seconds thought.
