Synscan V4 restarting when observing.


Recommended Posts

Hello, first time writing here so please do say if I need more info in the comments. I got a Sky-watcher Star discovery 150 Alt-az. I got everything set up but when after finishing allignment and viewing an object, when I want to look at another it moves to the object and restarts. Its not random, it always turns off and on when going to the second object, it doesnt matter which object it is. Week ago it was crashing when alligning to a second brightest star. I saw some posts about it but they were all talking about it crashing randomly and the comments said to try a new power cord. I never used one I was running it on 8 AA batteries. The software versions is second to the latest and the latest version doesnt look so nice. 

Edit: The fix was using a 12v charger. Since I bought it I had no problems.

More than likely to be the batteries. Although they may be new, they just don't have the power for the mount.

You're much better running it off a mains adaptor or a powertank.

Hi, as has been said the issue could by batteries but also have you updated the firmware? Even though the hc may be new to you the hc may not be up to date with firmware.

Firstly replace the batteries with a proper +12v power supply. If you insist on using batteries, get a fresh set of Duracells.  8 for £1 from Poundland won't be powerful enough.  Stalling while moving is also typically caused by some bad-contact cable issue.

Don't rush to update the firmware - it never causes this sort of problem.  If you try updating the mount with suspect power or cables, you could kill your mount permanently.

I understand all you are saying and suspect that, but I dont really understand this part. I update the controller by disconnecting it and connecting it using a printer usb cable. Thanks for the other advice.

I was thinking of that but shops near me dont have that an ordering online is not worth it. I have a laptop charger that has the same connection though it is 18v. Im not really knowleged in voltage and how much is needed so will that be safe to use. If not I'll sacrifice the 10 euros and buy it online.

An +18v charger will most likely kill your mount. 

Ubdating the firmware is unlikely to be as simple as connecting a USB lead, and as I said this is unlikely to fix the problem.  Firmware update is not a cure all.

      Hi everyone 
      So i have a problem with the synscan controller v4, when i want to update to the last version, first of all i connect and put the control in the update version, and then connect to computer and the program detects the controller. Then when i press updated to the Version 4.39.10, it only goes to 1.8%, sometimes to the 5% but not further. 
      Then i updated to a low version 4.2, and it updated the control but does not work with the mount anyways. 
      Hope you can help me.

      Greetings,
      I'm super happy to have found this forum of night sky enthusiasts and look forward to learning and sharing on this site! I am an amateur stargazer fortunate to live in a rural area with great dark skies. I'm used to using a GoTo Celestron.
      Unfortunately I'm having a problem with a newly purchased Orion SkyQuest XTg 10. 
      I've only used it a couple of times. Recently, when I turn on the power, the hand controller (a SynScan V4 GoTo, version 04.39.04) states a message "Both axes...no response!" which means the motors won't work. 
      I've unplugged all the cords & replugged to no avail. The power comes from a new Orion Dynamo Pro, 12 V, Lithium Power Supply which was recommended.
      Does anyone have any ideas what the problem might be?
      Thank you 🌟
