| Description |
|
In order to tell whether the controller has been power-cycled, the CCD focus motor steps are offset by 100. That is currently carried all the way out, which is confusing. The internal positions should be kept offset by 100, but that offset should be taken out everywhere above that. The positions which non-engineers might use are the arm vertex positions, which are in correctly adjusted microns from one end. |

I'm not sure that's the right place for such a comment but are you sure that 100 steps is sufficient ? We have recently seen that during a large move ( from 300 microns to 0 microns), the motor can hit the switch, causing motor status to be 'Unknown'.
