"Calibration Failed, star did not move enough"

[Carter Loewen]

Got a clear night for the first time in a while. Previously I used PHD2 on my MacBook running MacOS and worked flawlessly, no issues. I recently got APT and converted my MacBook to run a full version of Windows so I could use APT in conjunction with PHD2. 

Well tonight, I went out and got setup only to keep getting "calibration failed, star did not move enough". I tried everything, switching cables, switching guide star, polar aligning again, rebalancing, touching settings that supposedly would help. Nothing worked and I wasted the night in trying to fix whatever was wrong. 

Attached are my logs from tonight. I would love some help in trying to figure out what went wrong so this doesn't happen again. 

Thank you.

Hello Carter, First clear night in weeks and it all fails at the first hurdle - it could be me talking. So I'm not 'expert' by any means and to me, the Debug log mostly gobbledegook, so I'm chancing a guess. I notice it asks several times if ASCOM is installed? I think that sounds like a vital question, so maybe you should check you've installed the latest ASCOM platform?

Cheers,

Funny enough, as soon as I packed all my stuff up and went inside, I double checked if I had all the drivers and I was missing the ASCOM ones. I just don't know if that's the fix until I'm able to get back out there.

Apart from hardware drivers, ensure you have the latest ASCOM Platform in there as well.

I see you're guiding via ST4. Is that the only option for your mount?

Good luck,

Yeah I just downloaded the proper ASCOM software. Yes, ST4 is the only option. I know the SWSA can be finnicky sometimes since it has no Declination axis, so hopefully with the ASCOM drivers & declination axis turned off I won't run into anymore issues.

Hi Carter

You've only now mentioned what mount you have, and that it doesn't have a Dec motor.

So PHD2 has been trying to Calibrate Dec, and of course fails, and sends you a message.

So you should Calibrate with Dec Guiding OFF in PHD2.

You can guide ST-4 if you want to, so long as you get a good Calibration.
