Re: second attempt: meridian management with mach2 please...help

Hi Andrea,

So my question was directed to understand better the connection between
settings in AE tab and MERIDIAN tab, if they are the same and which is better.
Yes, that is true, but there is only one set of limits in the mount, so when a pier flip is issued, the limits will get reprogrammed for the destination pier-side and declination. During the pier flip, the scope can potentially point close to the meridian.

So, if you are trying to prevent a possible pier collision near the meridian, I don't think the limits can necessarily prevent that. There might have to be a multipoint slew algorithm developed, assuming I understand why you want the scope to avoid the meridian?

hello,
in the AE tab, it seems you can also set AR & DEC limits: this tab in my understanding has the same functionalities of
the "HOME/LIMIT" tab of non AE mounts.

In the help file: "the RA limits that you set here will override any custom meridian limit you may have set on the
Meridian Tab. These limits are the preferred choice for those using automation software...."

So my question was directed to understand better the connection between settings in AE tab and MERIDIAN tab, if
they are the same and which is better.

Thank you for your help,
Andrea

What do you mean by AE tab? What is your question about AE?



AE refers to absolute Encoders. In the Mach2 the encoders are not available for you to turn on or off, and they
have nothing to do with flipping the mount or reaching the meridian. The encoders are permanently on, cannot be
turned off. They control the axis positions and tracking speed.

thank you.
I think option 2 can work for me.
my final objective is to work with CCDAP , so after 45 min when a slew is commanded by CCDAP the mount
will flip.

what about AE tab?
it seems like option 2 but you can set also the behaviour when the limit is reached, no?

thank you again,
Andrea
