I have been having issues since day one of owning the Skyfi3.
Was using Skysafari 5 pro, then upgraded to 6 pro. Both versions exhibit the same issue.
I have the latest firmware on Starsense, Hand Controller (usb), Skywatcher Adapter, etc and latest Skyfi3 firmware (1.3.3)
The starsense setup works flawlessly standalone without the skyfi/skysafari. Orion Sirius Pro mount.
My procedure is to power everything up and do an alignment without the skyfi on or plugged in. After alignment I connect the skyfi and connect skysafari. The scope's position is displayed.
I have skysafari setup to use skywatcher synscan, but have also tried orion sirius and avx. All do the same thing.
After some time of being in use and Im ready to move to another target, when giving a goto or slew command through skysafari, the scope will start to move, the Hand Controller will lock up, sometimes the mount will even slew in a random direction. When the HC is locked up, I will have a spinning asterisk symbol on the right side of the HC screen. The scope will not slew using the hand controller when this happens. Skysafari will display an error saying it can connect to the wifi but the scope is not responding. I have to do a full power cycle of all gear and re-align to fix.
Things I have tried. Different USB cables. USB cables with noise filters on them.
The only thing that has seemed to help is last night I slowed the readout rate in skysafari down to 1 per second from 4. The scope worked for 4 hours before locking up.
