Re: Mach1 (spring loaded vers) has gear slop?
Thanks Rolando. I wondered if it was "sky" but seems to have been bad a month or more. But you're sharing pretty much same skies as me. So I'll see how it goes. Thanks for the reply. Still my shots have been fine. (does this new group allow images?) I HOPE... Y4 and whirlpool during recent 1/2 moon.

A unique COM port is assigned by Windows automatically. You pin devices to particular COM ports if you want their device ID to stay on it and not move around. One does not need to manually allocate them under normal circumstances.

Re: Com ports

I've had this problem and went into the devices software and assigned it a higher comm port that was not in use. Then in windows go to device manager and advance options on that comm port and assign it to the matching port you used in the device software. It's been a long time but I think that's how I fixed it. Someone can correct me if I'm wrong. Thanks, Charles Sent from mobile device.

Re: Mach1 (spring loaded vers) has gear slop?
Roland Christen
So my question is there another method or documentation of what I might do to take that play out of the RA mesh? There is no reason to take out any play in RA. That axis is always running in one direction and is never reversed, so play or backlash is not an issue. It doesn't come into play at all during tracking or guiding. Leave it be.
Run Guiding Assistant and look at the natural star motion when the mount is not being guided. It will tell you instantly what the stars are doing, how much they are moving due to atmospheric motion. If you get 1 arc sec RMS of natural star motion (scintillation) then no amount of guiding will get you less error. I recently checked my skies here in Northern Illinois when it was clear on Saturday. Stars were moving around so much (probably jet Steam) that i had 0.8 arc sec RMS values of just scintillation. I could not get better then that all night long with any guide settings. It's just the way things are in spring time around here.

My guiding is now at best .99 and averages around 1.50. Good enough for decent stars at my image scale but it makes me concerned. The corrections are very abrupt. I've used PHD2 for 3 years and know it quite well for tuning. I can't seem to get it to smooth out.
I believe there was a PHD2 update during this (good to bad shift). so it's hard to know if it's the mount or phd2.
With that said - I feel there is a good bit of play in the RA mesh. I have taken the slop out before using the 'thumb pressure" tuning trick. That isn't working this time. I move the weights/top of teh scope a good bit that I think is the culprit.
I opened the RA end of the box where the 3 gears are. (the middle gear turns freely easily). But it too seems to have some slop. ? Meaning I can wiggle the middle gear1 bit (1/16th?) inch or could say 1.5-2mm or so before it contacts the other gears to make them move.

I have seen the instructions for (old-style - no spring-loaded vers) which doesn't apply to me I don't believe. As noted above, the thumb/finger pressure on the release lever doesn't seem to work this time. Could this mean a new gear is needed in the box? What else could I try?

Re: Clutch Plug Removal on AP 900
Joe Zeglinski
Hi,
I had to replace all the clutch plugs on my AP-900
and it was a bear of a task, almost unbearable, even with AP’s special plug
removal tool. It was only possible thanks to George and his marvellous advice,
on the easy and smart way of using a 3 or 4 inch long (socket head) as a
“push screw” and my socket wrench, to pull the axle head off and
disassemble the axes. Then it was easy to remove the badly deformed old
plugs.
As usually happens, the DELRIN plugs aged and
flattened out at their tips (from a few years of being tightened down too hard),
becoming mushroom-shaped, and had spread out between the bottom of the clutch
screw hole, and the clutch axle itself. There was no way it was ever
going to be extracted, up the clutch hole, no matter how good the tool. The
mount axes had to be disassembled. Thanks to George’s instructions on how
they do it, the task was almost a breeze after that. Once the “push-screws”
easily did their job, I drilled out a larger centre hole down the old
plugs, and tapped some looser ones into the now empty clutch channel. I think
later, for some of them, I threaded the drilled plug – only half way in, to
produce a “tapered threaded” hole. That way, the tap then had enough grip to
then push & screw the old plug, down into the channel without much
force.
A little WD-40 may have helped loosen it from the hole
threads. The old clutch plugs not only formed mushroom
heads in the channel, they also thickened and embedded themselves into the hole
threads.
With the axles disassembled, the mushroomed head
did not need to force its way upward, but be screwed inward, for
extraction. *****************
However, the next time I have to do it – and I really
hope there will never be one – I think I might substitute the AP clutch plugs
with one’s I found on the web, in CHINA. Or, I will modify the standard AP plug
kit.
Those are almost the same, except they are “rounded,
bullet-shaped”, at the tips. I figure that their narrowed tips, rather than AP’s
straight cylindrical plugs, will not mushroom as much into the empty channel
space, beyond the diameter of the clutch screw hole, making extraction much
easier the normal way using the AP tool. Alternatively, I might put each new AP
standard kit plug in a drill or lathe, and “round-off” the tips to likewise
become bullet-shaped. That would probably be easier than sourcing from China,
where they might become unavailable over time, and possibly not precisely the
same size. If rounding-off would work, I would much prefer to trust the ones
from AP, and modify them. **********
Also, if those Chinese substitutes are used, you
should still source the regular AP clutch plugs to perhaps replace the
“bearings” on both axes. The same AP clutch plugs are used as “rollers” in the
race channel – i.e. there are not typical “steel ball-bearings”. You will
need a KIT of each, plus spares, since you will likely drop and lose some during
assembly - about 24 on one and maybe 22 in the other (?) axle. The DELRIN axle
bearing rollers may flatten out over time, just like the clutches, perhaps
shatter with age and stress. Eventually will need replacement as well, although
that has never been mentioned here, or even written about in any AP
documents.
The mount really was a joy to use again, after its
clutch rejuvenation, and I didn’t need to replace the ones in the bearing race
yet, since I am the original owner. But I suppose, under more frequent use
and heavier loading than mine, the axes may get “bumpy”, when one or more DELRIN
plug rollers chip or shatter, causing a log jam in the race channel. So, keep
that in mind.
Here is a link, to the Chinese company – to see what
those look like.
Actually, it would be nice if AP could be the source
of both the regular clutch plugs for the bearings, and bullet-nosed ones for the
clutch holes. The “rounded section” should be slightly longer than the channel
depth, to prevent even those from mushrooming and getting
stuck. Joe Z.

I just measured the new ones and old ones. The inside hole diameter is 2.5mm and the outside diameter of the plug is 7mm. I did note a bit of variance in hole size with the smallest about 2.3 and largest 2.6. One was 2.8 or so on one side. The plugs I pulled out are the same as the new ones.
