The emphasis of the motor tests has been on the repeatability of the travel limits. In most cases, the tests have involved repeated moves from the negative limit to the positive limit and then back again.

In early tests there were numerous anomolies on several motors, mainly in the positive travel limit positions, such that the limit positions seemed to be bimodal. These anomolies seemed to cease after one to two hundred limit-to-limit cycles. The supposition is that the metal disks wore down burrs which caused occassional binding between cogs. In any event, variations in limit positions needs to be monitored. This can readily be done as the limit conditions are always logged and, therefore, can be tracked.

Note that, prior to 03/13/00 all motor moves were done with a speed of 32212 counts per second, which is slower than the anticipated final configuration.

All motors were homed on 01/06/00, 02/29/00, 03/04/00, 03/06/00. Also power cycles occurred on 03/04/00 and 03/06/00. There were some individual motor homings and resets and, undoubtedly, some power cycles, reset, and homings of which I am not aware or did not keep track of, especially during the Feb/00 site visit. If necessary it is possible to find most of these in log files.
