Hi
I am in early days setting up EKOS on a Pi 4 as well as a separate Linux ( Kubuntu ) laptio.

Equipment - EQM35 pro mount, ZWO camera, Sesto Senso 2 focuser.

So I can connect both Imaging and guide camera no problem and these seem to work fine imaging and tracking. I am connecting the EQM35 using Skywatcher - EQMOD settings in the configuration, and with the cameras all is ok. However if I try to add the Sesto Senso as the Focuser then the Mount will not connect although the Sesto now will using a new powered USB3 hub.. I have tried using the Skywatcher - SynScan setting but also not connecting

Any ideas would be very much appreciated or pointers to do some more error chasing

Thanks
