Joe,

If your CP4 was not working correctly then all bets are off on the accuracy of values in the log.

Subject: [ap-gto] Odd APCC LOG entries



Hi Ray,

I’ve been trying to read through the few minutes of the log file, when my second CP4 went berserk, besides
several other weird entries,
I keep seeing DOUBLE entries from 3DVIEW, for changes in DEC.
For example:

0012563 2018-04-21 22:23:34.096: Debug, 3DView, Dec Angle Changed = 41.5518291419454

0012564 2018-04-21 22:23:34.096: Debug, 3DView, RA Angle Changed = 180

0012565 2018-04-21 22:23:34.096: Debug, 3DView, Dec Angle Changed = 88.4602777777778

That RA mount speed is pretty darned fast, to do a 180 degree-Turtle, in zero time.

How can the DECLINATION be in TWO places at the exact same time – Time Travel, DiLithium Crystal –
sheeesh?
No wonder this second unit ... also had a stroke, and suddenly ... it was Deceased !!!

I have even seen the first DEC report a positive angle , and the very next line, repeated at the same clock time,
of a huge DEC negative angle. A few times BOTH DEC readouts have EVEN been identical, but that is pretty
rare.

Here is just one example of this dichotomy – the CP4 must be super colossal, to flip that fast in less than a
millisecond.

0000295 2018-04-21 22:18:51.282: Debug, 3DView, Dec Angle Changed = 46.3716666666667

0000296 2018-04-21 22:18:51.282: Debug, 3DView, Dec Angle Changed = -226.371666666667

How do I interpret such strange messages – it isn’t even a complimentary angle?
Is one of these a “servo gear angle” ?

I think we need a Manual, rather than just an Appendix section in the user guide, to understand the APCC log.
