Yep, I have a CEM70 and it does that (although not always).
No big issue for me because I setup and tear down every night. Might be an issue (or better, an annoyance) for ppl with observatory and stable setup though.
My workflow is: setup everything, staying awake a bit to check that all is working fine, going to bed because meridian flip and auto-park will take care of everything, wake up and see that parking is horizontal (even though I set vertical) and, most of the time, still reporting slewing to. Therefore I click "goto home", turn off everything, etc

FYI, I sent the latest firmware to Jasem yesterday, and this morning he pushed it to the repo :)
If someone has the mono version, now it should work fine.

A couple of other params I don't know how they should be set:

HCG/LCG gain ratio
Offset

Someone has any idea?

I've made a comparison between the ASI2600MM, QHY268M and RisingCam/Altair IMX571 Mono with the numbers found on their respective official websites:

To me it's even more clear that the RisingCam camera should always be used at gain 100 (which is gain 0 on other cameras).

Actually, there's another important advantage: to reduce the read noise. If you look, for example, at the 2600mm graphs, you'll see that at gain 100 the read noise is half that of gain 0.
If you look at the Risingcam's graphs, you'll see that gain 0 is always the best option for both LCG and HCG.

Yep, that HCG should be used with gain 900 and greater. But looking at the graph, I'd never use gain 900 with HCG on this camera. It simply doesn't seem to be the best (again, according to the graphs).

I asked them about the amount of memory and how to use the graphs they provided, because it seems that for both LCG//HCG the best would be gain 0. The reply was:Engineering should come up with a standard version for all customers, because they said a different thing to another user wassat.png

The more I look at the graphs, the less I understand.
Why would they suggest to enable HGC at gain 18db (900)?
According to the graphs, everything gets really worse at such high gain compared to, for example, gain 3.95db.
I'm really puzzled...

They replied to my email with "engineering will look into this".
Let's hope they'll do that one day..

Ah ok, I've just seen the graph with the gain/gain(dB).
Man, this camera works in a weird way xD it even start at gain 100.
