Now she is absolutely unbelievable. She does better on two feet than most with four! And the thing is, she’s fast and agile. Really Fast!!
Watching her run is a thing of beauty. Snow even? And, finally, I see by her demonstration at the end of the video how vicious she can be with you if you don’t do what she wants.

Beautiful video. Thank you very much

Jim

No, she really doesn't need it. If she did I would make one. She actually picks herself up. Very strange to see. Here is a video of how well she gets along:
https://www.youtube.com/watch?v=InTUAsTBGS0&t=13s

I had X-rays taken and the vet said it was an old injury that wasn't taken care of, lower spine damage. This is her "normal" now. She isn't in any pain.

Nice night tonight, looking at the moon and of course Venus in the Pleiades.

Clutch Plug Removal on AP 900

Robert Chozick <rchozick@...>
 

I just replaced the clutch plugs on my 2010 AP900 mount and wanted to describe my experience and give some pointers to possibly help someone doing it for themselves.

My mount had gotten to the point where my RA axis would barely turn when balancing. Major variations in movement of my counterweights showed no difference in balance. My DEC axis has never been a problem. It has always balanced easily. I decided to go ahead and replace my RA axis clutch plugs.

I ordered the special screwdriver tool and plugs from AP. I got extra plugs for future changes but only needed 4 to just change the 4 RA plugs.

The first one came out like a charm exactly as described. "Great - this will be easy" I said. I just gave 2-3 fairly hard hits with a smaller size hammer and screwed it out. You have to apply a lot of downward pressure as you screw it out but as it gets to the end start applying less pressure or you will have the problems described below. Even if you do apply less pressure at the end you may have the below issues.

The second and fourth one had the same issues. The plug came out fine up to the point it got the the edge of the channel but at that point started going backwards. I let off the pressure but it would only turn in place. I decided that the plug needed to be larger in diameter to be able to screw out. (These plugs are really only the width of between the threads but are larger in diameter only because of expansion from use and the tool going inside to expand them) The plugs have a hole through the middle. I took a screw and turned it about half way through the plug to expand its diameter. I took out the screw and then put the screwdriver tool back in and could turn it a bit more using very slight pressure. I could get it to the point it was about 3-5 mm above the edge and then took a small pliers and turned it for the remaining rotations to get it out. On the fourth one i squeezed a bit too much and almost had to start over but it came out. Be careful how much you squeeze.

The third one was the worst. I had to do the same procedure as I described above for the second and fourth but the plug kept going back in. I reinserted the screwdriver tool a few times and had to whack it with the hammer again. It did finally go above the edge but as I took it out with the pliers half of it crumbled. The remaining stub proved to be enough to grab to unscrew it with the pliers.

Thankfully this procedure worked and all 4 plugs have been replaced. I am glad i did not have to take the axis apart since George’s description of that process sounded awful.

Once you get the old plug out you just drop a new one in and screw the clutch knobs back in. George recommended not putting any oil in so disregard that part of the instructions.

If you have real problems with your clutch plugs it is worth replacing them. My RA axis balances beautifully now. I put a scope on the mount and the axis moved for very slight changes in the counterweight.

If you do not need to replace the clutch plugs I do not recommend doing it just for maintenance purposes.

I decided that when my mount is not in use I will leave the clutch knobs slightly loose so maybe the plugs don’t deform as much over time. I usually leave my mount outside without a scope on it. I just have a pier and a cover so I don't leave scopes or any electronics out. Your situation may not allow doing this.

I hope I can save someone some grief when replacing clutch plugs.

Re: AP 1100GTO Absolute Encoders Price

 

Hello Tony,

 

The current and original prices for all of the encoder upgrade kits are shown on this webpage:

Click on the radio button for the kit that interests you and the price will appear above.  The prices probably changed about a year ago when I arranged a blanket order with Renishaw for a large quantitiy of encoders. Current prices are not guaranteed for the future.

Re: Mach1 Unable to Find Home Position Suddenly

Mikko Viljamaa
 

The CP3 is bone dry, nothing wrong there. On another positive note, the mount tracked well all night again as far as I can tell and had parked itself spot on. This is the second night in a row. The start was as bad as the other night (below right and remember that the correct position is close to Meridian) and it's almost like the initialization goes wrong somehow (or doesn't always happen) but I don't know how to verify this. Only after I power off everything including the SGP things seem to improve and when I do a trial slew and it comes back close enough (that same 1/4" typically) I know that if I start the sequence, it probably will plate solve and do it's thing. That's what happened yesterday also.

The photo on the left taken during the daylight was one when the mount was supposed to park itself from 3 to 4. Not pretty...

By control panel, do you mean the CP3 servo drive controller? Yes, getting moisture in there can cause a problem. You may want to dry it out and try it afterwards.

No keypad, nor did I have a small enough Allen wrench to check the small worm gear screw. But I used a marker to mark it and the axle to see if they have moved after a slew or two. No movement and as said, I don't think this is a mechanical issue. As a a matter of fact, I'm starting to see similar issues when the control panel had moist in it and when the mount started slowly to slew and suddenly speeds up. This happen twice now tonight for the first time. Also and I don't know if I have been able to confuse the whole thing but after playing with the mount now for awhile and asking it to park 4, it will hit the pier. That's how much off it is now.

i'm out of ideas at the moment.

Re: Mach1 Unable to Find Home Position Suddenly

Here is another thing you can try if you have a keypad. Disconnect all external connections and plug the keypad in. Turn power on.

Start the mount from present position
Send the mount to Park3 (don't turn power off)
Send the mount to Park4 (don't turn power off)
repeat the above sequence and see if the mount gets an increasing error.

If the error increases same as with the ASCOM driver, then it points directly to a mechanical slippage problem. Something is slipping in the geartrain between the motor shaft to the RA axis itself. Could even be loose clutch, but I doubt that.

Nothing probably to do with this but previously (older versions of AP V2) when you launched the driver, it asked if you want to unpark the mount. The current one does not do that and I notice that even though I have not initialized the mount, the screen shot I attached says that the mount is unparked.

I will try this in a moment but I still think this is some simple silly issue we are missing now and which has something to do with the time or location of the mount (or it's assumption of one of these)

Re: Mach1 Unable to Find Home Position Suddenly

Roland Christen
 

Any time any app opens the AP ASCOM driver it will initialize the mount, whether it unparks or not. Apparently your app (SGP) opens and unparks the mount automatically.

A mount is NOT initialized when the ASCOM driver shows RA=+12hrs and Dec = +90*00:00deg.
A mount is initialized, Dec will show any angle other than 90*00:00 deg.

I join this group in 2009 just before I took delivery of a Mathis fork mount with A-P electronics. But now I just took delivery of a 1100GTO and took it for a spin last night. Kudos to A-P for the fit, finish and attention to detail, plus the good documentation. Love the new GTOCP4 control box. Here is a pic of my temporary set-up. The whole thing is going into a roll-off roof observatory that I'm building this Spring.
