Re: Error in AP driver

Chuck Faranda <mail_lists2@...>
 

Yeah, but the printed command protocol doc from AP indicates that it is looking for and giving longitude in a 0-360 format. I think the firmware author needs to chime in to solve this one......

Chuck,

as the AP protocol is extending the LX200, I read back the LX200
description (http://www.meade.com/support/LX200CommandSet.pdf)
This indicates the presence of the sign, and that East longitudes are
negative (so -180 to 180 is the expected range).
The trace from ASCOM - and the log from PulseGuide both show a value
near 360 (but wrong: 355*50 for E 5 50).

Re: Error in AP driver

Ray,

I have autoconnect set to No and want to keep it as is; so the
location is prompted at every power cycle, which - after selection-
erases the value in the mount and sets it in the range 0..360, which
PulseGuide cannot cope with (-180..180)

See also my reply to John W.

this sounds like maybe a change to the keypad software would fix the

negative longitude.

Hi Ray,

This is Rev L. CP3 (this is a brand new Mach1).
In my latest tests, I used PulseGuide and only PulseGuide (1.30).

This is the exact sequence to show the value is not retained
after
power cycle:
- set the longitude to W 6 50 via the keypad for location 1
- power cycle
- start PulseGuide and get Site Long: all fine
- set longitude via PulseGuide to E 5 50, then click "send to
mount"
button
- observe that PulseGuide reads back the value correctly
- exit PulseGuide
- power cycle
- select location 1 via the keypad
- shown: W 6 50 ... too bad ...

Hi Ray,

No: unfortunately, the value written by PulseGuide is _not_
retained
properly after a power cycle if the longitude is East.
Last test I did was to set the longitude to W 6 50 then
change
the
longitude via PulseGuide to E 5 50, then click "send to

button, then power cycle then select location 1 again on the
controller.
Then I inspected the longitude: back to W 6 50 - so the value

I'd appreciate to have AP to check what is going on: I am now

east

Re: Error in AP driver

Pierre Henrotay
 

John,

The sequence cannot work exaclty like this: after the power cycle,
the keypad prompts for location selection; selecting location 1 will
replace the mount values. I habe autoconnect to No and want to leave
it as is.

So I refrained from entering the location 1 and got the
initialization dialog in PulseGuide, where I selected Cancel (did so
whenever PulseGuide was started).

And indeed, the value read back by PulseGuide equals the value it
originally set (and I bet it is set internally to something strange
like W -005:50:00 !!)

Of course, next time I select the location, the value will be changed
to something that PulseGuide cannot retrieve.

So it seems (GTO3 4.12 REV L):
- AP is using 0..360 (unlike LX200)
- AP is having a problem with Gg for East longitudes (storing 355 50
instead of 354 10 for E 5 50)
- PulseGuide is using -180..180 but this leads to strange values (W -
005...); side effect unknown
- PulseGuide cannot read above 180 (and hence East longitudes from AP)
- selecting the location overides the mount value, in the format
0..360

What if you don't use the handset at all after using pulseguide, i.e.:

- set the longitude to W 6 50 via the keypad for location 1
- power cycle
- start PulseGuide and get Site Long
- set longitude via PulseGuide to E 5 50, then click "send to mount"

- observe that PulseGuide reads back the value correctly
- exit PulseGuide
- power cycle
- start PulseGuide and get Site Long

Does the value read back by pulseguide equal the value it originally set?

Hi Ray,

No: unfortunately, the value written by PulseGuide is _not_
retained
properly after a power cycle if the longitude is East.
Last test I did was to set the longitude to W 6 50 then change
the
longitude via PulseGuide to E 5 50, then click "send to mount"
button, then power cycle then select location 1 again on the
controller.
Then I inspected the longitude: back to W 6 50 - so the value
was
sent but not accepted.

I'd appreciate to have AP to check what is going on: I am now
thinking that the AP controller returns an incorrect string for
east
longitude when the Gg command is issued.

Re: foam for cases

observe_m13
 

I used very high density open cell dark grey foam. It gives but quite
reluctantly, similar to the closed cell foam. Your choice of the
closed cell polyurethane foam should be excellent as well. For cases,
I managed to scrounge an old aluminum monitor case for the 1200 ra
section and a "Scopeguard" style case built for a heavy piece of
obsolete equipment for the dec section. Keeping them as small as
possible is really important, especially for the RA section. At 50 to
55 pounds, bulking it up is counter-productive to say the least. I
would think that even a half inch thickness of good closed cell foam
would be adequate with good handling and transport techniques; and up
to an inch of foam for even better protection if one isn't quite so
careful. More foam than that would be necessary if you were building
these cases for rough handling and shipping, but every inch adds
weight and bulk. Keeping them as light and small as possible is really
important for the 1200.

Rick.

I am going to make a set of cases for my 1200 and a couple sets for

they shipped with but only use 1 layer of it to save space. I will
not be shipping with it but just moving it in and out of my truck for
the occasional star party so it will not have rough handling

I got a sample of the grey firm foam like found in most equipment
cases but it seems very mushy/ soft and would compress a great deal
with the weight of the mount and I fear offer little support unless I
use several inches. The foam that it came with is just the opposite,
very firm but if AP ships with it, it must be good.

I will build the boxes using Baltic Birch plywood with a removable
lid and had thought of making it so that the interior where the mount
sits is exactly the same size as it shipped, but the box ID size using
1 less piece of the shipping foam. The Dec assembly is not that large
so original size is not a big deal, but it would be nice to reduce the
size for the RA assembly mainly.

Any thoughts or opinions from what others have done?

Re: Broken clutch knob

Wiggins, Rick
 

Hi Pete,
I have seen the flurry of posts. Let me offer some simple
suggestions. Don't put any glue or any other stuff down in the hole.
I think that is a low probability of success and higher probability
or making the problem worse.

Next, Are you comfortable with working with the suggested tools? If
so, then take the easy-out screw extractor advice. If not, then have
someone that is comfortable with tools do this or take it to a
machine shop. Of course, you could always mail to AP for repair.

1. First take another stainless steel screw of the same size, put it
in you vise and do a test run of the set punch, drilling, and easy
out insertion. If you can do it in the vise, you can do it in the
mount.
2. If it is too hard to center the dril and not slip, then do this
setup with the drill press and light slow drilling.
3. After you are comfortable with the process, set up your mount so
that you can drill straingth down into the screw.
4. Use a set punch to provide a small starting dimple. This would be
a light tap with the hammer, so you get just a small dimple to
prevent the drill from skating across the screw surface.
5. Drill either with the drill press or very steady and carefully
straight down to make a pilot hole. Use a very small drill bit. Be
careful not to break the bit!
6. Now drill a larger hole to the correct size specified bt the
screw extractor.
7. Slowly and carefully install the easy out.
8. Slowly and steadily back out the screw extractor, making sure to
apply only perpendicular torque. Make sure the wrench is held
perpendicular to the extractor and that the extractor is parallel
with the screw. Dripping a light oil down the hole (only one drop)
may help if you are worried about the screw being struck or cross
threaded. Wait 5 minutes for the oil to soak around the threads.
9. Completely remove the broken screw.
10. Clean the hole of oil and debris.
11. Celebrate with Holiday Drink of choice!

Cheers, Rick

thought to myself "hmmmm. Interesting construction that could let

I realize now that what had probably had probably happened is the
aluminum had split but not broken right off. If I had realized the
(somewhat odd) construction of the "bolt" I would have backed it
out
and replaced it right away. Live and learn.

Thanks for all the advice. I'll let you know how it goes. I've
already
had both the Dec section and RA section back to AP at least once,
so
I'd rather avoid another repair visit. I sold my backup G11 last
week,
so it would leave me without a good mount!

Since the top of the broken stud is 3 mm down in the threaded
hole, if
glue of any sort is put on top of it and the other piece is
threaded
in, any excess glue will be forced out of the space between
the two
broken pieces and into the threads both above and below the
break,
since there will be no where else the excess can go. I
seriously
doubt that there is anything that can be done to seal the
threads
adequately to prevent this, since the glue is relatively
incompressible. If the amount of glue used is so small that
there is
no excess to squeeze out, it might work, but the proper amount
is
probably difficult to estimate.

Re: Error in AP driver

Pierre Henrotay
 

Hi Ray,

This is Rev L. CP3 (this is a brand new Mach1).
In my latest tests, I used PulseGuide and only PulseGuide (1.30).

This is the exact sequence to show the value is not retained after
power cycle:
- set the longitude to W 6 50 via the keypad for location 1
- power cycle
- start PulseGuide and get Site Long: all fine
- set longitude via PulseGuide to E 5 50, then click "send to mount"
button
- observe that PulseGuide reads back the value correctly
- exit PulseGuide
- power cycle
- select location 1 via the keypad
- shown: W 6 50 ... too bad ...

Re: Error in AP driver

Hi Konstantin,

The value is being rejected by PulseGuide I think because the keypad wrote a
value over 180 degrees to the mount. The range is -180 to 180 in the LX200
protocol so I that is the range PulseGuide validates.

In any case if I am understanding the problem correctly the keypad firmware
is not writing the correct value when above 180 degrees anyway... or the
firmware is wrongly converting it.

I purchased cases from Scopeguard (I think AP uses them as well).
They are constructed very well and I have been pleased with them.
Scopeguard uses Ethafoam in the cases which is like the foam used to
ship the mount. The Ethafoam works great. I had custom cases built
with custom cutouts for the ethafoam so I would not have to remove
the dovetail when transporting the mount. You will probably need a
case for each axis.

the occasional star party so it will not have rough handling

I got a sample of the grey firm foam like found in most equipment
cases but it seems very mushy/ soft and would compress a great deal
with the weight of the mount and I fear offer little support unless I
use several inches. The foam that it came with is just the opposite,
very firm but if AP ships with it, it must be good.

I will build the boxes using Baltic Birch plywood with a removable
lid and had thought of making it so that the interior where the mount
sits is exactly the same size as it shipped, but the box ID size
using 1 less piece of the shipping foam. The Dec assembly is not
that large so original size is not a big deal, but it would be nice
to reduce the size for the RA assembly mainly.

Any thoughts or opinions from what others have done?

Re: Error in AP driver

Ray Gralak <rgr@...>
 

Hi Pierre,

So it seems that the problem might be fixed by changing the keypad firmware
to write in the range -180 to 180 instead of 0-360. I think because
Pulseguide writes in the range -180 to 180 the value is retained properly
after a power cycle.

Chuck,

as the AP protocol is extending the LX200, I read back the LX200
description (http://www.meade.com/support/LX200CommandSet.pdf
<http://www.meade.com/support/LX200CommandSet.pdf> )
This indicates the presence of the sign, and that East longitudes are
negative (so -180 to 180 is the expected range).
The trace from ASCOM - and the log from PulseGuide both show a value
near 360 (but wrong: 355*50 for E 5 50).

Re: Broken clutch knob

Mark Squicquero
 

The previous post warning about glue in the threads is right on. There is no way to prevent "gluing" the broken piece to the mount with this technique. This will only work with an exposed broken segment. You have to protect the threaded hole no matter what you do in this case. The best suggestion so far was to use a left handed drill of the appropriate size. You must also protect the threaded hole with a small piece of tubing while drilling so that "when" the bit wanders it won't destroy the threads for the new clutch screw that you're going to put in. Just get a piece of brass tubing or similar, cut a small piece and place it in the hole. Then use it as a drill guide. As was previously mentioned, the increasing "bite" of the drill as it penetrates (with left handed torque of course) will eventually back the screw out. Use cutting oil, low rpm, moderate pressure. Worst case scenario: you'll need an extractor if it doesn't back out by itself, but the threads will
still be intact.

Re: Broken clutch knob

observe_m13
 

Hi Pete,

I have good nes and good news. I took one of the knobs out of my 900
and then took teh stainless screw out of the knob. The black knob
appears to be aluminum and the screw has been threaded in to give a
solid access point for a hex key in order to tighten down teh knob.
Aluminum would strip far too easily. What remains inside your mount is
about 1/2 inch of threaded aluminum and, lo and behold, since the
stainless screw was in there, there has to be a threaded hole in the
center of it. I should have looked more carefully but I am betting
that the stainless screw is either 8-32 or 10-32 thread, not that it
matters much. What you want to do is get an easy-out for the aluminum
stub stuck inside the mount. You will have to probe with some small
bits or a toothpick and see how deep the hole already is. Measure down
to the lip of the piece that remains inside and then measure inside
the existing hole. If it is of sufficient an easy out to fit that hole
should work just fine. If the easy-out requires more depth or a larger
hole, just carefully drill it deeper/larger with the required bit. The
hole itself will ensure that the bit remains centered.

An alternative would be to get a small bolt with the same thread and
size as the stainless bolt is. Carefully thread it into the existing
hole until it stops, noting how deep you can put it in. If it goes in
1/4 inch or so INTO THE STUB, then back it out, mix up the tiniest bit
of epoxy, apply even less than the tiniest bit to the threads of the
bolt you just removed with a toothpick and thread it back into the
stub in the mount. Let it set up until the epoxy is hard as nails and
back out the stub using the bolt. When I say the tiniest bit of epoxy,
I mean just that and I can highly recommend JB Weld. The smallest
swipe or dab, just barely filling the threads of the bolt on about 1/4
or less of the bolt surface area that will be inside the stub. You
want to ensure beyond any doubt that this stuff doesn't contact any
part of the mount itself. Once it sticks and sets, it is done,
virtually forever.

Again, if you don't feel comfortable about doing any of this DON'T do
it. Give AP a call tomorrow and see what they recommend.

I thought you were talking about the mount having a problem with a
broken off threaded section in the mount itself. That is serious and
is what a picture of would be worth a 1000 words.

As you can see, the device is actually a hollow threaded
aluminum tube
with the knob part screwed into it. The walls of the tube are
not that
thick, but should take quite a bit of torque without breaking. All I
can assume is that the knob got banged longitudinally somehow,
and the
tube broke.

The rest of the tube (with the "outer" thread) is unfortunately
still
in the mount.

Yes, PulseGuide validates the return value in the range -180 to

is why you are seeing 0's.

Can you try changing Longitude from the hand controller, power
cycling, and
reading it back from PEMPro? Do not connect with the AP ASCOM
driver at any
time when doing this test in case it tries to change Lat/Long. You
can even
open PulseGuide's Log window to see what commands are being
exchanged.

Not a silly question at all.
Yes, I:
- set the correct value in the controller (it shows E 5 50)
for
location 1
- select location 1
- start ASCOM tracing then MaxIm
- connect to the telescope (using MaxIm) and show setup
display
- I click "Get..."
- the setup display shows E 4 10

Confusing: the string returned by the mount for Gg as shown
in
the
trace is +355*50:00 ... which is definitely wrong (360 - 355
50
00
gives indeed 4 10, not 5 50 !!)

Something wrong in the firmware itself ?

Also please tell me what appears in the dialog afterwards.
This
code
is very simple. The mount is reporting the CORRECT

from
your trace below +355*50:00 in AP's format really means E
005:50:00
in standard terms (they measure 360deg positive westward
from
the
prime meridian).

Here is how the driver works: After putting in the correct
LAT
and
LONG settings in the dialog initially, click APPLY. This
will
set
the values into the mount controller (you can also set them
into
the
controller by hand but BEFORE A GET make sure that the
controller
is
initialized and you have selected the correct location (I
suspect
that you had not done this when getting the bogus values).
After
that, clicking on GET LAT/LONG should correspond to the
correct
values

Hello,

If further information or tests are needed, do not

to
contact me.
This is a Mach1 mount, 4.12 GTO keypad. Driver is

Helper2.dll is dated 7-apr-2005, 45056 bytes.
I wonder what is the impact. Any idea ?
