Hello everybody,
Last night was the first night in a week or so I could get out. Set up all went fine, did everything like always and the mount went whacko again, kept slewing even though it should have been on target. Tried the tip I had been given, go to Tracking in the menu, turn off tracking, go back to Eq-North turn back on. Several times but didn't work. Soooooooo, tonight it's a fresh charged power pack. The 5 amp power cable will be here tomorrow. Let's see if that helps!
I had this happen to me in DEC right after I received my AVX. I checked the DEC cable and it turned out to be faulty. I re-crimped my own and have never had a problem since. I don't know if this causes your problem but it can't hurt to tweet the connections if you have a multimeter.

Yes I have done the factory reset.
Are you talking about the flat wide cable plugging into the DEC Port on the main assembly? Just to satisfy my curiosity I switched ends and re-inserted. I'm about a half hour away from seeing.

I'm sorry that didn't work for you. It has fixed my issue on more occasions than I care to remember.
I would also say your next step is cable replacement...
Good Luck and please post up whatever you find that works for the next person!
Cheers
Good thing I still have that lacing pony.......it held the connector ends while I pulled two ways, up and away from them as I checked the continuity. Found no faults.
Clestron 5 amp 110v power cable cam today, it puts out 12.20 volts. Celestron fresh charged power tank puts out 12.89 volts...is this making the motor turn faster therefore the travel rates faster?
We'll see Wednesday night weather permitting.

I don't think so, they are stepper motors.
Too bad it wasn't a cable problem.
Are there any differences between using the handset and computer control? One way to check it is to use PHD's manual controls. Just in case the handset has some problem.
Also, to rule out ASCOM, try the ST-4 controls, select the on-camera option in PHD.
Are there differences between RA and DEC? If so, consider switching the cables and see what happens, I know you already said the cables are fine but it's an easy double-check.

I did install CWPI but haven't used it yet, PHD2 for some reason didn't like it. I have used the manual control that floats around on my screen and it works. Let me backstep here, the problem I'm having happens before I fire up PHD2. Before I started using a guide camera I was able to focus on a target and take 30 sec. exposures over and over on Sharpcap, now I can't even get 15 seconds. The mount starts slowly moving too fast.

Man, it just sounds like somewhere there is a setting that has the mount tracking on the wrong speed. I remember you saying how the Moon stayed put yet the stars were trailing.
Since you have done a factory reset and your power is good, I don't think the mount is the culprit. Something in some software somewhere is hosing you.
Have you tried a different capture program to see if the same thing occurs? Something like NINA or FireCapture? If you see the issue there, then double check the driver settings.
More straw grasping from me...

This is your third thread regarding your afflicted mount and there are many posts dealing with your dilemma. So pardon me if I don't remember, but have you tried a different hand controller (if you have access to one) to see if that temporarily fixes the problem?
I have tried PHD2's manual control that's on the screen when connected to the mount, it works. I got a reply from Celestron Tech support, the first questions was which power tank I'm using and how old? Have I updated the Firmware? Have now. They gave me a link on more precise Polar Alignment. My new 5 amp power cable came yesterday. https://www.celestron.com/blogs/knowled ... n-eq-mount
I haven't tried another program , I did download and install CWPI but PHD2 didn't like it. I'll check that out today.
The first of the month I was out back using the power pack, it went sour.
Next night I was at the campground I used the trucks cigarette lighter, worked great for awhile then suddenly PHD2 starts telling me " Your mount stopped slewing", over and over.
Next night I'm using the power pack, OMG it worked flawlessly for hours!
My Celestron CGX struggled to keep on track until I realised that it thought I was at the default Greenwich Observatory location. It doesn't remember the entered time, date and location until you enable the Real Time Clock.
Your problem appears to be more intermittent than that but it might be worth a look?
