I am going to send an email to Leon, but I am assuming he won't get back to me tonight, so I thought I might see if anyone has a solution on here tonight...
I recently purchased a new computer, set everything up, and my focuser took a bit of finicking with (changing phase selections, messing with computer settings, etc.), but I got it to connect and respond to commands. It worked great the first few nights. I was having issues with PHD2 and APT the first night with the new computer (after exposure completed, PHD2 would say it is guiding but it wouldn't loop, and the guide graph stopped responding), but I reinstalled APT and messed with my settings some more, and got it all to work, including the focuser. I had a great night the second night, but my issues with my focuser started then.
When I set up the second night, the focuser wasn't responding. I had to mess with the settings again to get it to work (I don't remember exactly what I did). It only took me a few minutes, so I forgot about it. I brought everything inside, connected the camera, guide scope, focuser, and filter wheel, and everything appeared to be fine (but I didn't test the focuser).
Tonight, I set everything back up, connected my camera, then my filter wheel, then my focuser. The focuser connected and I was getting temp. readings from it, but it was not responding to commands again! I tried messing with the phase select, the driver settings, the USB hub settings, power settings, etc. I made sure my usb devices weren't turning off because of low power, and I even re-installed the drivers and software--no go.
Astrophotography Tool connects with the software, and I even get temperature readings. But for some reason, it will not respond to inward/outward commands.
The focuser is plugged into a USB hub, which also connects my ASI1600 (which acts as a hub for my filter wheel and guide camera) and my mount, and the USB hub plugs into the laptop. I use a 12w USB AC adapter to connect the power to my focuser.
Has anyone had this issue before?
