| Stephen Brooks 2005-07-23 13:50:22 | The bigger S1 optimisation allows the initial S1 to be very long (from 0.8 up to 1.8m) and the rod Z position has been scaled accordingly so it can be 0 to 1.8m from the beginning of the channel. This means that a combination of short (but big) S1 with rod at the maximum Z value will put it right inside S2... though I doubt this is a better design (be funny if it was though!). |
