| Description |
|
Twice now the first theta map ever taken had inexplicably stalled motors. Since we take the fastest map first, and depend on that finishing (having the motor drive e limit-to-limit) that causes everything to fail. We should either run a "limbering up" run before acquiring data, or be prepared to re-run the first one. At worst we need to make sure that the first/fastest run failing causes the notebook sell to fail so that it can be manually rerun. |

Seen on several/most modules. Will add retries (3?) in the notebook. FWIW, some of the theta motors which did not span the desired (>360 degrees at very least; >375 better) range miss by a lot. We see motors with ranges of 200,250,300,320, etc., which look fine when we retry. One possible problem is that we currently do not retry until after several (6) full maps have been made, at various ontimes. So we do not really know when/how the motors end up behaving. |
