Re: Mach1 CP3 pier crash!! (Similar to CP4 crash in another thread)

Joe Zeglinski
 

Hi,
 
    You should be aware that under certain conditions, ANY Pyramid power supply, including the one sold through AP,  may NOT reset its “thermal breaker” after a dropout, for upto a half hour. So, you may give up and walk away too soon. Then all, is fine the next night, but the PYRAMID trips again. The Pyramid (old linear technology) supplies are not very efficient, but are generally well designed. Just heed their warnings and limitations.
 
    If you still have it, carefully read the Instruction Sheet.
Here is  Section #5,  which I transcribed from mine. Substitute “TRIP” ... for their word  “WORK”.
Yes, it does “work” as designed to do. The power supply breaker will trip,  eventually, even if there isn’t an immediate short circuit overload. So, any long duration or repeated mount slews, will eventually have the Pyramid protect itself, so you can take an imposed  coffee break, before going back to imaging :-)

 

(A-5)  WARNING / DEVICES.

 

THIS UNIT IS WELL BUILT WITH A WARNING!   SHUT DOWN FUNCTION.

THE WARNING / SHUT DOWN FUNCTION WILL WORK  -  UNDER THE FOLLOWING UNUSUAL STATUS:

 

1)    THIS UNIT IS USED OVER 15 MINUTES AT 100% OF RATED LOAD.

*

2)    THIS UNIT IS USED OVER 25 MINUTES AT 80% OF RATED LOAD.

*

3)        THE OUTPUT OF THIS UNIT IS SHORT-CIRCUITED/OVER LOAD/OVER TEMPERATURE

 

NOTES:

1) IF THE WARNING/ SHUT DOWN FUNCTION IS CAUSED BY THE ABOVE ITEMS # 1 AND 2 THEN THIS UNIT WILL RETURN TO NORMAL WHEN THE WARNING/SHUTDOWN FUNCTION CONTINUES TO WORK ABOUT 15-30 MINUTES.

*

2) THIS UNIT IS INTENDED TO CONTINUOUSLY WORK AT 70% OF RATED LOAD DESCRIPTION OF THE WARNING / SHUT DOWN FUNCTION:

STEP I.  THE OUTPUT SHUT SHUT DOWN.

STEP 2.  GREEN LED OF NORMAL OFF

STEP 3.  RED LED OF PROTECTION ON.

    Hope this helps explain the situation you had been having. Check you device power requirements.
When it happened to me, the overload eventually tripped the PYRAMID, and while I was away from the mount for a short while, the power supply cooled off and came alive – and the mount resumed its slew, right into the pier, before I could hit the main power switch. I wish the Pyramid would have stayed powered off, but it seems to have been designed to reset and resume without warning and “unattended operation” – NOT always a good thing.

I have an observatory.  The Pyramid ordinarily doesn't get very hot.  I tested its output voltage this evening, and it tested at 13.8.  So it came back after appearing dead.  Meanwhile, the little Radio Shack p.s. is connected to the CP3.


Re: Mach1GTO RA is lurching back and forth a LOT

Roland Christen
 

If you did a balance with the worm gear backed off, you may have backed off the worm in a forbidden position. The ONLY configuration that you can back off the worm is in Park3. If you tried to back off the worm in any other position you may have accidentally scraped the worm teeth across the worm wheel and thus damaged both worm and worm wheel.

This scraping happens when you are unbalanced a lot and you disengage the worm with the lever. The axis will move suddenly and you will hear a scraping sound as the teeth run over each other. That is why we strongly recommend first doing a rough balance using the clutches, followed by a fine balance with the worm disengaged in Park3 (scope and counterweight vertical) and then moved to where the scope and counterweight are horizontal. Under no circumstances should you ever disengage the worm while counter shaft is horizontal. Same is true for the Dec axis.

Subject: [ap-gto] Mach1GTO RA is lurching back and forth a LOT

When new (November 2017) my Mach1GTO was very smooth. I could shoot 5 minute subs unguided at 480mm all night long. 

Now the RA has regular "lurches" (as I call them). See the PHD2 Guiding assistant pic below.  The RA jumps 2"-8" in the time a 5 second guide exposure is shot, THEN is steady-ish for a while. Of course these jumps are too quick to guide out.  I have run PEMPro, PEC corrected tracking seems to be about 1" RMS.   I have set the RA "backstop" a couple of times with the thumb&forefinger method.  It seems sometimes, in certain areas of the sky, the "lurching" doesn't happen.  But it happens most of the time.

Has anyone else experienced this?  Any ideas of what to try to fix it?

My setup for the following data was:
  • Mach1GTO
  • Permanent pier: 8.625" OD steel pier bolted to 12" diameter 84" deep below ground concrete pier.
  • Celestron EdgeHD 8 at f/10 2032mm focal length. Screenshots below taken at 2032mm, usually I do photography at 1422mm with this scope.
  • Losmandy D dovetail plate mounted to Celestron scope
  • MoonLite focuser
  • ZWO Off Axis Guider
  • ZWO ASI174MM Mini guide camera.
  • 0.59 arc-sec/pixel on the guide camera
  • 2x USB and 2x 18ga power wires through the mount
  • Focus controller, dew controller, and USB hub are mounted on the scope, along with numerous cables.
I have set the "backstop" on the RA motor.  The box with the motor can rock back and forth slightly but it almost takes 2 hands to move it a millimeter or so.

Re: CP4 Time & Location

Wes Atchison
 

Thanks guys, sorry for taking up you time.  After I posted the question I opened up " Telescope Setup" and realized there was my answer.  Since getting the mount recently I have very little time out using it and forgot I had entered locations for several sites.

Thank you again for all the great support, wish other companies stood behind their product like you guys do.

Subject: [ap-gto] CP4 Time & Location

Trying to get my head around how the CP4 gets the time and location from a computer.  I have read the manual for the CP4 and searched the topic on the group page.  I understand the information from the Keypad when powered up is the location selected in the Keypad.  If only a computer is attached when the CP4 is powered up I understand the time from the computer is uploaded to the CP4.  Where does the location come from?  Also, if a GPS is connected to the computer can that be used as the source of time and location?

If this information has been discussed before on the group I apologize or bring it up again but my search did not find an answer to my question.

Re: APCC 1.8.1.1 latest update window missing value

Ray Gralak
 

Hi Yves,

I checked my laptop again. No anti-virus or Windows Defender enabled. Gave APCC access thru firewall just in
case but nothing. I'm still able to check for updates with my all other softwares. It's very strange !!!
Microsoft has been breaking things left and right with Windows updates so I think this is probably being caused by a .Net Framework update that is either missing or broke .Net Framework HTTPS calls. Unfortunately since you are running Windows 7 you may not get updates automatically. There may not even be an update available to fix the problem since Windows 7 is no longer supported by Microsoft.

Curtis,

Consider one from Powerwerx too.  They make two, one with a set voltage and two Powerpole jacks on the front, and this one, with an adjustable output.  I started with a Pyramid but that thing got super hot every time I had it out, was heavy and bulky, and didn’t really supply enough power.  These are built very well, I’ve been using them for years without issue, and they run cool and quiet.  Very nice.  https://powerwerx.com/variable-power-supply-digital-meters-30amp
