Hi All

Is there a Part 4 somewhere ?

?

Virus-free.

#70486

Those were not released videos.?

There is eventually going to be a full series, but we are working with Ray right now to fine tune PEMPro for Gemini, so we are likely going to re-do this from the start

Richard I think i saw some comments from you in the PEMPro forum?

Hi Brian

?

YES – was having trouble with drift when PEC ON and then with the Gemini Drift Compensation tool in PEMPro. Basically could not get it to “converge”.

?

Hence interested in Part 4 and hoping you got past the drift issue, you must have as I understand you use PEMPro PEC with your Losmandy mounts.

?

Ray said I have some strange frequency that he hadn’t seen before. He was going to look at it some more, ………. ?

?

I will try again in a week or so when the skies allow. Do it all again on a single night and see what happens. Send Ray the logs etc.

?

Cheers

?

Hi Richard,

?

Have you tried creating a Pec curve with the 0.2x rate in PEMPro? Then set the guide rate to 0.2x. I think drift you are seeing should be reduced.

Dear Brian,

Thank you for sharing these pre-released episodes?with me.

Your experience with video shows... the Jetsons theme music is cute.??

I watched one recently on balancing?the scope load.? On that one I'd add these points:

1. put the mount at CWD and tighten down the RA clutch, before putting on or taking off the scope.??

2. Always put or or take off the scope after the counterweights are in place...Never put on a heavy scope when the system has no counterweights.??

3. Add all your weights to the counterweight bar before you put the scope on.

4. After you add the weights, put the "toe saver" bolt into the end of the counterweight bar.?

5. Soon as you put the scope dovetail in after the weights are on, put in the front 1/4-20 bolt to prevent it from accidentally?slipping out.?

6. Gemini-2 has a "balance" indicator (Menu / Mount / Balance).? ?Put the counterweight bar horizontally, then look at the balance indicator on the Gemini-2 unit.? Use the indicator to help perfect balance.

I'll look at the other videos when I can.? I still have to get my G-2 unit internet connected!? I did get one of those yellow Internet wireless boxes and I used them to connect my older Pioneer receivers to get internet radio.? Now to use one for the Gemini-2 too.??

__________

One of the two new gearboxes I got from you has a tight spot in the gearbox rotation. Feeling the rotation by hand, it has a slight tightness on one spot, but not as bad as another gearbox (the RA gearbox of the G11T that I got).? The other gearbox I got from you seems better.??

I suggest you hand rotate the output shaft of your stock of gearboxes and look for ones that have this tight spot in the drive axle rotation.? Surprisingly this stuff does show up in the PE because the Gemini motor and Gemini drive is sensitive to its drive current.? If you find defective gearboxes, you can complain to your supplier as you have volume purchasing power.??

Stay well and safe,

Michael

Hi Michael

thanks for your feedback

For any future feedback on specific videos It would be great if you could start a new thread here, or better yet add your comments to the youtube?video itself. I fear your input will be buried in a thread that won't be easily found in the future
