Hi, The Celestron focuser just stopped working. Using 3.1.0.425 and all was working fine about 2 weeks ago. I can connect to the mount and control it and I can connect to the focuser (USB - serial through the hand controller), SGP sees the current focus, but can’t change it. I checked the cables, confirmed port with ASCOM 6.1 platform, confirmed focuseer works with cFU (celestron focus utility), ran a recalibration just in case. I did download two sets of drivers; first was the QHY5III224c so that I could use that as my imaging camera and the second was Orion Startshooter Autoguider. I pulled my Nikon out and used the QHY guider as my imaging camera and made the OSSAG my guide camera. I had to hook the guider up with both the USB cable then the nasty ST4 cable.
setup:
Celestron Edge HD 11"
CGX-L mount
PHD 2.6.6
SGP 3.1.0.425
Ascom 6.4
Windows 10Pro on HP Elite 8300
