Re: Odd behavior with keypad startup - runaway mount!

Roland Christen
 

the mount runs away and doesn't respond to the stop command
 
Does it run away the moment that you turn power on? Does it run away when you press a direction button? How does it run away, please be specific.

Subject: [ap-gto] Odd behavior with keypad startup - runaway mount!



I own a 1600GTO Mount with the CP4 Controller - and have a crazy error if I start up the mount with the keypad.  With the keypad (but not the APCC), the mount runs away and doesn't respond to the stop command!   The mount is roughly 2 years old - did I miss a firmware update to the keypad?

Sounds like it could be a stuck or damaged key on the controller.
 
Or a corrupted hand controller firmware image.

Re: Park Position South Celestial Pole

Geert
 

Strange, I think you should check your settings for geographical position then, also in any  program you use to connect to the mount and ascom driver - they should be same.  You cannot define a custom parking position in the keypad, but you can put your mount with the keypad in the position you wish, then select Park 0, this will park the mount at present position and resume from there next session.

Best regards,

Geert

Hi Geert,


Unfortunately no. The Park 3 position tries to twist my mount completely around and down which I imagine is to Polaris. 

Probably worth noting that it also seems to tell my mount that is has travelled to the Northern Hemisphere to, because once I abort a Park 3 position, she has no idea where she is anymore. I have to restart The SkyX and turn the mount on and off and do a sync to get it working again properly (its a messy process using the inbuilt park positions). I imagine this problem is inherent to Southern Hemisphere owners maybe. 

Is there a way to tell the mount a new Park position that it will remember?

Re: AP1600GTO No Guiding

The problem I am experiencing is when I hit the guide button the guide star just starts moving in RA until it is off the screen. It is like sidereal rate is being stopped. I'm using the same settings I've been using all the time which are the default settings, I've played around with some just experimenting but it still does it. 
 
You probably have the "Pier Flip" checked which will drive the star off the guide box if you are on the wrong side of the mount.

Also it is worth mentioning for good measure. The guide camera works. The guide setting move the telescope with the GPUSB. How do I know this? On the Maxim DL guide tab in the camera control window, there is a move button. When I hit that button, it opens up a window with arrow keys. I can hit those keys and the mount will move.

If I leave a star on the screen using camera one with 1 second exposure in sidereal mode with no tracking she'll stay centered all night, it is only when I hit guide that the guidestar travels off screen. 

When I calibrate I a lways get the message that the star didn't move more than 5 pixels in X, but it has always said this (even when I've changed to settings). 

I've changed the guide speed on the mount hand controller as well but that has no effect. 

This all started when we had a power cut on Sunday. Prior to that she guided perfectly.

Any theories welcome.

Re: The SkyX and Recal

Roland Christen
 

When is the best time to uncheck that box and use the sync feature please?
 
The only time you might want to use Sync is when you first set the mount up after unpacking it from the shipping boxes and placing a telescope on the Dec axis. At that point the mount internal electronics has no previous information about where it is in the sky. So you manually send the mount to a known object (either with your hands and a loose clutch or with the direction buttons), then you bring up the co-ordinates of that object and press "Sync". Note, you have not gone to the object via a GoTo command, rather you have manually found the object and need to tell the mount that this is the place in the sky where the axes are pointed.
 
From that day onward, you never have to use this sync function again. If you are permanently set up, you simply turn on power, the mount servo calculates from its internal memory where it was when it was shut down last time and uses that information to go anywhere in the sky using the GoTo functions. It does not need for you to tell it where it is pointing because it has an internal memory of the last place where it was left or parked when power was removed.
 
Of course you can use the Sync again each time you start up, but it is too easy to make a mistake that way. For instance you may tell the mount that it is pointing at Aldebaran when in fact it is pointing at some other place. When you do that, you effectively cause the mount to be in error and you won't find any other objects.

Subject: [ap-gto] The SkyX and Recal



Hi,

Would just like to confirm my process for pointing my AP1600GTO with the SkyX. 

When I start up the mount and the SkyX (TSX), I connect to mount, I slew to a star using TSX, I centre it either with the hand controller or the TSX move buttons, then I synchronise using the TSX software (not the AP pluggin), then I hit the 'Recalibrate' button on the AP window that is visible in TSX. Everytime I slew to another star I hit the Recalibrate button. The mount points well, and this post is just a confirmation request that this is the best way to do it.

I take it the Recalibrate button just adds to the pointing model?

There is a checkbox on this window as well that says

"Convert Sync to Re-Cal (highly recommended)". 

When is the best time to uncheck that box and use the sync feature please?

Thanks

Ray




Re: AP1600GTO No Guiding

when I hit guide the guide star drifts more than when just in RA. I'll keep fiddling. 
 
You may have Pier Flip turned on in Maxim, which will send the opposite error signal to the mount and will slowly drive the guide star off the chip.

Hi Timo,

So you are saying that there are no setting on the mount that can turn off autoguiding settings? If so that is good because that will narrow it down to Maxim. 

I've done a recalibrate, used default settings, setting the correct output (GPUSB). 

The guide camera settings are all perfect as well. I get the guidestar, I can send commands to the mount manually, when I hit guide the guide star drifts more than when just in RA. I'll keep fiddling.

Did the reverse x checkbox get unchecked? Or vice versa. Maybe it thinks it is on tho other side of the meridian from where the calibration was really done.

I believe that once the PEM state is set in the CP-X controller regardless of which device sets it, it will stay set at that state till another device resets it.

Re: Had my first pier crash...

Hi Joe,

 

Thanks.

 

Yes, I definitely did make a point of saving your “USB cable fix” suggestion when you sent it out (Sun 10/16/2016 11:52AM). I will be trying this out once I get myself organized.

 

Thanks again!!

Hi Tony,

 

    Are the cable connections to the hub somewhat loose, side-to-side? This may be either from wear, or being twisted sideways a bit by cable drag or bundle weight,  at the scope.

 

    You could try my “USB connector fix” which I posted here recently (16/10/2016):

            “OT: Fixing loose or worn out USB cable plug ends”

 

    Even a single wrap of “bare, non-foam” clothes dryer vent type, aluminum duct tape, would snug up the cable’s connector with just a single layer wrap, no matter how loose the hub sockets may have become – or even started out loose, right  from the manufacturer. This is even worse for the small square-end USB-B type plug that plugs into older hubs and CCD cameras. The aluminum tape sticks very tightly to the plug end, and won’t unglue after many insertions. The hub socket plastic wall prevents its wearing out. A roll of bare aluminum tape is cheaper than replacing a USB  hub.

 

    I found that some USB hubs may have “softer” white plastic walls, which deform after a several insertions, although I think StarTech is likely one of the better manufacturers. In any case, for telescope USB cables at least, this fix is probably going to help, even before the problem gradually sneaks up on us, and we waste many nights tracking it down to a “tired USB hub”. No use trashing a hub, if the next one develops the same loose fit. The cable fix, in specific uses, avoids the problem.

 

May be worth a shot, especially if it potentially prevents problems with other USB cables as well.

These connectors were suspect from the moment I hooked them up. I’m not talking about the cables themselves, but the connectors on the Hub itself. I was expecting better QA and build from StarTech.

OK, what state did netstat show? CLOSE_WAIT? Are you running Windows Server 2008 x64? There was a known timestamp bug that caused sockets to get timestamped far into the future, which seemingly caused sockets to wait forever before closing.
