I would prefer the old behavior where if dawn approached then it initiates the shutdown

Jasem, yes I think they work fine. I think its the firmware on the mount (I need to update it). I tried motion control East/West when near the pole and it does move but incredibly slowly. Also tried on the handset and the same result....
In the end I just manually moved the mount in RA by disengaging the worm and moving approx 30deg as per the PAA instructions. It worked great. The only difficulty was the first attempt. The polar error was about 1 degree and my FOV is only something like 35" so it was hard to see exactly how far to move. But doing it in 3 passes it worked perfect. Its a really useful tool.

I had some clear(ish) skies on Friday night and polar aligned using EKOS. I got it to within 20 arc seconds of the pole... The Ekos polar align is a bit quirky though. For some reason it couldn't slew the mount between images so I had to manually slew which is fine. Also you need to have polaris in the frame which can be initially tricky with 35" field of view. Also a bit dangerous, at one stage the mount was going to crash into itself but I unlocked the RA worm just in time. So take care when polar aligning. The polar adjustment on the CEM120 is very smooth.

Thanks for the firmware tip lazjen. I haven't updated it yet. I need an RS232 to USB adapter before I can update the handset so I'll get one of those. I'm currently connecting the PC to the mount via the USB socket on the base of the mount.

Moved it to the observatory yesterday. There's my dad doing some cable work below...
The through the mount cabling and internal usb hub works perfectly. I've 3 devices plugged into the saddle and 1 usb cable coming from the mount to the PC
Also it provides 2x12v power outlets on the saddle for camera & filter-wheel. This is really useful. Its coming from the main power going to the mount base. Although this won't allow powering just the CCD but thats no big deal.

No clear sky yet for polar alignment and first light. Will update again

I can connect to my CEM120 via direct USB. Seems to work fine.

If the CEM40 has the same serial command set as other mounts (good chance it does). Then in theory you could just add it to the models map here
github.com/indilib/indi/blob/master/libi.../ioptronv3driver.cpp
Then rebuild indi locally and test it.

I see this in the log file
`iOptron CEM120\nPlease ensure remote device name corresponds to actual device name`

But you are using a CEM 40?

Maybe try change the baud rate in the indi driver settings. I had to change this to connect direct to my CEM120. I set it to the second highest one 11520
