Re: Which to Choose; Absolute Encoders or 92 mm Stowaway

I have one of the older Mach 1s which I love and is still performing wonderfully. I too have wished as with my AP 900 and 1200 it could be broken down into two pieces.

If we could somehow split the Mach2 so that the heaviest part is less than 30lb, is that worthwhile?

Sorry to pick up this old thread, but I will wholeheartedly cast a vote for being able to split the Mach 2 into separate pieces.

When I image from the backyard I need to carry all my equipment up about 8-9' of stairs. I found that it is doable with the Mach1, but the 42 lb. weight of the Mach 2 has me a little worried. I'm not a big guy, and have had a minor knee surgery and three major hip surgeries (last one just 10 days ago), with the prospect of a few more down the line. Anything towards reducing the Mach2 mount weight is music to my ears.

Re: Mach2 Status Update

 

Well folks, this morning I was notified that my Mach 2 will be shipped this afternoon.  I'm very excited.  A big thank you to Roland, Marj, and Karen!

For a reference, I put myself on the Mach 1 list on October 17, 2018, so you may be able to determine where you are from that. 

If you're still waiting too, there is hope. :)

Thanks Karen

Hopefully Illinois can open back up sooner than later, once it becomes more obvious that the virus is not rebounding in the states that have opened back up.

Hang in there.

Re: Motor Gear box removal instructions (newer auto-meshing model)

John O'Grady
 

Hi Charles,

Thanks for responding and I apologize if my earlier post wasn't clear. 
I have a motor gear box without cover (cap) screws. 
Therefore, I'm at a bit of a loss as to how to proceed.

Thanks,
John


Re: Motor Gear box removal instructions (newer auto-meshing model)

Charles Thompson
 

I believe the screws are deeper in those holes that have the cover screws. It takes a little precision to get the allen key all the way in there and hit the mark. That might be what you are missing. 





Thanks,
Charles

Subject: [ap-gto] Motor Gear box removal instructions (newer auto-meshing model)

Hi,

I'm looking for instructions on how to remove the motor gear box on my AP1100GTO.  I have the latest model (I believe) of motor gear box supporting auto-meshing capability with the lever for disengaging the worm from the worm wheel.  I can't find removal instructions for this specific model of motor gear box.  I'm wanting to re-grease the mount and the instructions that came with the grease kit describe an earlier model that has cap screws on the exterior.  I hesitant to proceed opening things up without the matching documentation.  

I checked the documents on astro-physics website and the files on groups.io but I may be overlooking which manual is the correct one to follow.
Can someone point me in the right direction?

Thanks
John

I had a similar issue to this with my AP1100.  I adjusted the backstop, but that didn't help.  I followed some additional adjustment instructions given by Roland here. Worked like a charm!

Worm tooth mesh is only one of several possible reasons why the RA axis could rock back and forth. One reason, other than worm mesh, is that the end play nut has come loose and needs to be tightened up. This nut holds the worm bearings in place and can be reached by removing the small round cover on the side of the gearbox.

The problem with trying to get answers on a user group is that there is never any meaningful information, we only hear about the symptoms. However, if you call George by phone, he can run you thru a series of checks that can pinpoint what is really happening. George is available to help AP users on regular business hours, so either give him a call or send him an e-mail and set up a time when you can be at your mount.

AP has a procedure for adjusting the mesh between the worm and the worm gear that will eliminate the play in either axis. The play is easier to detect in RA because of the large moment arm provided by the counterweight shaft. Declination should be checked to if it has been a while. The procedure is available on line under Support.

The backstop does not prevent the axis from rocking back and forth unless you put a huge amount of force on the axis that causes the worm teeth to lift out of the worm wheel. Checking axis backlash should never require huge force to try to move the axis, rather it should be just finger pressure back and forth. If it doesn't move with finger pressure, then all is well. However, if finger pressure does move the axis, then it is an indication that the worm bearings are loose, or even that the main bearing end play nut has come loose.

Give George a call.

Then it's the backstop. It's largely irrelevant though. I would leave it alone.

HI Peter,
   I haven't done anything yet. I'm waiting for Rolando or George to give some advice. Perhaps the very small rocking in RA is normal or needs to be adjusted. Like I had posted earlier, I don't see or feel the rocking motion on my AP1100 on either axis.

Hi Joe,

How often should PEC training be redone? I have an older 1200 mount with a CP3 that carries a sixteen inch
Newtonian in a permanent setup that is used about 5 nights/month.
You should probably check it every 3-4 months to see if it needs a new curve. Apply a new curve if the old curve isn't correcting as it did when it was originally loaded.
