Sounds like I my have to rethink this...I certainly didn't think about having to try it and reposition it in the lathe. I guess I will need some practice. Thanks

Turn PE OFF, run 15 minutes UNGUIDED with PHD2 showing the guider graph of star position. Any guided graph is basically useless for mount troubleshooting. Rolando

I'll check PE. But after cleaning I did a "record" and it finished so I suspect it recorded a clean PE. I REALLY hate sending in the whole thing. But would be nice to get it all tweaked. (PHD

What is it supposed to do? Well for one thing it would tell me if the problem is on the worm wheel since doing this will expose a fresh set of teeth, and it is highly unlikely that each of the 225

By the way, is it possible that you have PE correction turned on and you are playing back some bad data? We had this happen once on a mount at the Mauna Kea visitor center. Someone had manually

sorry for spamming... but I'm trying to track this down. Looking at the good and bad logs (header) for settings. I made a change. Working log shows I was connected to the mount "astro physics" and

Looking at older logs. The problem seems to have started recently. (there should be no reason for it on my part "HARDWARE" speaking. Is there an option in PHD that might cause this? I had been

I tried the park1 - (move manually to park 5) unpack from 5 and (no change) what is that supposed to do? In my head, I can't think of any benefit/change. The worm still continues doing what it

Next night - I'll do a 2-3-4 worm cycle unguided. I also may have one in a older log. I'll work on that. LAST NIGHTS. -- Ron Kramer https://www.facebook.com/Ron.R.Kramer

Joe & Tom, I understand the concern, but provided there is a positive length location (registering to surface of Chuck) AND the cutting gear train is kept engaged (so nothing can move independently(

Success! That worked Ray.. PHD2 was guiding perfectly...I was getting total rms values averaging .3" and down to .25" at times over 3 hours last night. Seeing was very good, with a light breeze at

Len, I tried anti-vibration pads years ago when I lived in Japan and observed from a 15th story balcony. I found the pads made touch induced vibration worse (such as focusing) but somewhat reduce

Hi Len, Interesting short cut with testing the part, but I would be concerned about “repeatability”. Tom would have to not only mount the part, back into the lathe chuck in two directions,

Tom, "I might as well get some use on my new mini lathe. I'm thinking of delrin or brass." For your adapter use brass or aluminium, Threads in delrin are harder to do than expected unless everything

Your problem may be more than this can solve, but there are anti vibration pads which could help: https://tripodpads.com I have them for my Eagle and the AP portable pier, although I got them

One other thing that would be extremely helpful is if you ran the mount for about 2 worm cycles (about 15 minutes) with guiding effectively off so i can see what the worm is actually doing. Posting a

Ron uploaded the GuideLog to PHD2 forum. While he does have dithering active, the frequency is unrelated to the 'kicks.' As he notes, it is 6.4m +/- 1s every time within the precision of PHD2. If

Ok, that looks like a worm period for each. Rolando

That's nice but what is the time period between each pulse? Rolando

I'll post then then try groups interface. I logged out my best guess on each incursion. There are no seconds so I had to estimate. This would be the later set of errors that kicked UPWARD about
