Re: AP130GT + older rings without center top hole

My camera + OAG is the old workhorse: STF8300 and OAG8300 + ST-i guide camera.

Not sure that you can get the above setup from Diffraction Limited anymore.

How about your off axis guider, pretty good results? What guide scope and camera?

Mach 1 ra motor failure to move the the west.

crib409acme425
 

the other night I set my Mach 1 up with a RASA 8 as a trial before New Moon. this was a new scope to me.  it was balanced , no cabling issues and in fact with the clutches loosened the scope was free to spin in ra and dec with a light touch.  Now to the trouble.  I noted it was not tracking in RA plus when ever I tried to use the Keypad to force it to move to the west the RA motor noise would last about a second stop with a second short burst and that was it.  I could go to the East and use the keypad to move N and S.  The battery was well charged.  Two mornings before I used this same Mach1 for the Lunar eclipse with out issue.  
That Night I took the whole thing down and reassembled in my garage.  In the am I tried the K pad on my 1200 mount.  No problems.
 I hooked the electronics up again, on the Mach 1, using the same battery as the night before and everything worked including tracking a phantom star .
It has worked ever since as I have tried to see if it would fail.  What could have been wrong? I did not look at the stall light I guess because it would move N, S and East and freely move with clutches released. 
The other issue I have is that the ra gear train noise in ra slewing is not always of  the same frequency.  It seems to vary a bit.  thanks cjacobson


Re: "Limit Reached" at meridian, not meridian limit.

Eric Claeys
 

I think I figured it out.  When I tested it, DEC was 89 54' 14.3 sec, which is close to 90 degrees, and when you're close to 90 degrees the meridian limits don't work.  When I backed off DEC a degree, the "Time before limit reached" went to 1.5 hours, which is what I'd expect given the position of the scope.


"Limit Reached" at meridian, not meridian limit.

Eric Claeys
 

I just created Meridian Limits but am getting unexpected behavior.  When tracking, I get "Limit Reached" when the mount gets to the Meridian, not when it gets to the Meridian Limit.  I've successfully used this many times in the past and don't know what's changed.  The picture below shows my limits, and shows the "Limit Reached" message even though the mount is nowhere near the Meridian Limit.
Am I doing something wrong?

I have the rings attached to an SBD12 lower dovetail. 
 
Will the spacing on the rings on the SBD12 + SDDAPB riser blocks on the ring tops allow any current AP Losmandy plate to fit with the correct lengthwise spacing? I have a 14 inch AP Losmandy plate LMDAP4567. Will it fit lengthwise with the spacing of the rings and risers?

Re: My AP1100 CP4 died (I think ..., need confirmation)

Cheng-Yang Tan
 

Hi Marj,
 I got a piece of non-conductive foam that had the right thickness to compress the board down when the cover is screwed back on. See photo.

 Interestingly, I see flux residue on the pins of the processor but nowhere else. This could be due to age or something else. See attached photo. I didn't bother cleaning it with flux remover because the CP4 works. I have photos that I took under a microscope if you're interested. Anyway, this is for your info.

My CP4 serial number is CP4-0476.

I'm glad you solved it. Actually Marj came up with the solution, so I am naming her "Employee of the Day". Maybe I'll make a Pizza for her tomorrow, with all her favorite toppings.

 

By the way, there should have been a small square of foam on top of the board to keep it in place. On later versions of the CP4 we used a different standoff that has screws to keep the board in place.

Hi Roland,

  That was the problem! I pushed on the main board and could feel the board going back into its socket. It moved quite a bit. I have no idea why it would have moved out of its socket because I've never dropped it. But then I'm the second owner, so maybe it was jarred a little bit loose during this second shipping and I do transport it in and out to setup every time. And over time, it popped out.

 

I've tested it fully cabled up and no more problems: it talks via USB and slews find in DEC. 

 

Thanks again!

It is held in place by standoffs. Push on all 4 corners. There is a long connector underneath, and you can see if it is fully seated.

One other thing to try. Open the cover of your CP4 and push down on the small circuit board to reseat the connections. It is possible that it came loose from the main board. It is highly unusual for a CP4 to simply die. Let us know if that works for you.

Yes, initially it lite red.  As soon as I directed east, the yellow light immediately went on and the mount would not move in the east direction. After restarting, the mount would move west, but not east.  Directing east caused the light to turn yellow and motor stall.

The "Motor Stall" warning will occur when unsafe limits are exceeded. This is not a warning that something is wrong with the motor or electronics, it is simply telling you that the software has turned off the power to the motors to prevent your scope from being damaged. At this time we use the same error code for all situations where the motor power has been turned off. It probably could be changed to indicate not "motor stall" but "motor power deactivated".  However, we have many other software challenges right now and this one will have to wait a bit.

Be careful that you don't use something that's conductive, or you may have infinite problems. Electronic foam is slightly conductive to allow static charge to dissipate to ground.

That's when the stall error popped up.
 
After taking it back indoors, the CP4 LED no longer lights up :(

The "Motor Stall" warning will occur when unsafe limits are exceeded. This is not a warning that something is wrong with the motor or electronics, it is simply telling you that the software has turned off the power to the motors to prevent your scope from being damaged. At this time we use the same error code for all situations where the motor power has been turned off. It probably could be changed to indicate not "motor stall" but "motor power deactivated".  However, we have many other software challenges right now and this one will have to wait a bit. Be assured that nothing bad has happened to your electronics or the motors.

By the way, there should have been a small square of foam on top of the board to keep it in place. On later versions of the CP4 we used a different standoff that has screws to keep the board in place.

Hi Roland,
  That was the problem! I pushed on the main board and could feel the board going back into its socket. It moved quite a bit. I have no idea why it would have moved out of its socket because I've never dropped it. But then I'm the second owner, so maybe it was jarred a little bit loose during this second shipping and I do transport it in and out to setup every time. And over time, it popped out.

I've tested it fully cabled up and no more problems: it talks via USB and slews find in DEC. 

Thanks again!

Yes, initially it lite red.  As soon as I directed east, the yellow light immediately went on and the mount would not move in the east direction. After restarting, the mount would move west, but not east.  Directing east caused the light to turn yellow and motor stall.

Yes, initially it lite red.  As soon as I directed east, the yellow light immediately went on and the mount would not move in the east direction. After restarting, the mount would move west, but not east.  Directing east caused the light to turn yellow and motor stall.

Anyway, it was a very weird night. After powering up, with the CP4 LED lit up, I wasn't able to talk to the CP4 with USB. I changed USB cables and used my backup laptop and both wasn't able to talk to the CP4. But I was able to talk to it via TCPIP. In APCC, I can move the mount in RA but not DEC. That's when the stall error popped up.
 
After taking it back indoors, the CP4 LED no longer lights up :(

The "Motor Stall" warning will occur when unsafe limits are exceeded. This is not a warning that something is wrong with the motor or electronics, it is simply telling you that the software has turned off the power to the motors to prevent your scope from being damaged. At this time we use the same error code for all situations where the motor power has been turned off. It probably could be changed to indicate not "motor stall" but "motor power deactivated".  However, we have many other software challenges right now and this one will have to wait a bit. Be assured that nothing bad has happened to your electronics or the motors.

I pushed on it. But it didn't feel loose. But after doing that, the LED lit.

I'll work on it later this evening ...

Thanks!

Hi Steve,

 

One other thing to try. Open the cover of your CP4 and push down on the small circuit board to reseat the connections. It is possible that it came loose from the main board. It is highly unusual for a CP4 to simply die. Let us know if that works for you.
