Re: East Slewing Doesn't Work on AP1100

It wouldn't be a motor stall if the N-S and W buttons work. It's definitely a situation where an errant sync or recal has placed the axis hour angle underneath the mount.

The somewhat mysterious and mostly undocumented meridian safety limits in the CP4 firmware will turn the CP4 light amber, but so will a motor stall, low power situation, a motor cable problem, a motor relative encoder problem or a CP4 I/O problem.

I am still only guessing on the CP4 firmware but I had my mount sent to George in July, 2018 and if I recall correctly he updated the firmware.  Version VCP4-P01-11, 12/19/17 is the latest before July, 2018.  I know I have never updated it since then.
