Re: AP1100GTO AE Is Totally Lost...How Do I Reset It

Tony Benjamin <tonybenjamin@...>
 

Okay, I think I figured it out. Had to loosen the clutches on both the Dec and RA and then ran Park 3 and manually aligned the RA and Dec then did a slew and a RECAL and all seems good again :)


AP1100GTO AE Is Totally Lost...How Do I Reset It

Tony Benjamin <tonybenjamin@...>
 

It won't even go to Park 3. Even when I disconnect the mount it keeps tracking fairly quickly (200x?)

How do I get it to figure itself out? I don't recall doing anything odd to it?

When new, my Mach1 (2017) was just under the +/- 3.5, or 7 pk-pk.  I redid my PEMPro curve a couple of weeks ago, and found it to be just over 9".

With my PEMPro curve applied, it's now less than 1" pk-pk.  Guiding is exceptional with my three 9 lb counterweights at the top.

Subject: [ap-gto] 900 Clutch Plug Help

 

After sometime off from using my 900GTO mount, I realized I needed to replace the clutch plugs on the right ascension unit.  I ordered the removal tool and new plugs.  The first plug removal was a learning experience and didn’t get totally removed, the other three were no problem.  I started to disassemble the R.A unit to get the first plug out.  I didn’t realize it was filled with plastic rollers.  At present I have been able to re-assemble it with two rows of rollers and a center axis that just doesn’t seem to now fit into the RA head properly.  Does anyone have the procedure to re-assemble the unit?  Should I send all back to Astro-Physics at this point?

Help,
Bob


Re: Counterweights...How Much Is Too Much Too Balance? AP1100GTO

CurtisC <calypte@...>
 

Just within the past week I added another 18 lb counterweight to my Mach1.  That allowed me to shove most of the weight to the top of the shaft, using a 10 lb to set the fine balance.  Scope is a TEC140ED with cameras.  To my great surprise, it's made a significant difference in PE.  My mount still doesn't meet the original spec, but whereas 20 p-to-p was typical before, now it's down to 11 p-to-p.

I balanced my PW 12,5 with two 18s and two 10s, and use C clamps to balance the scope. Its right in balance.

Just wanted Dale to know I appreciated the suggestion about ASCOM for DSLR.  I downloaded the ASCOM.DSLR files at https://github.com/FearL0rd/ASCOM.DSLR/wiki

This is the latest version that started with Vladimir Torkalo's inital steps. https://stargazerslounge.com/topic/317522-ascomdslr-ascom-driver-for-dslr-camers-canon-nikon/

The driver installed easily and shows up in Chooser the same as any ASCOM-compliant device.  You can link to Canon SDK, BYEOS, recent Nikon, Pentax, and some older Nikon cameras. I only have interest in Canon and, by extension, BYEOS; hence cannot comment on the other options.

Still some glitches plus work to do at my end, but this was a big step forward!

Hi Liam,
With a little time for observations, I will find the time to make these tests and measurements to see what it is. Losing the hotspot on my smartphone placed at 1m and on my PC located at 2m50 left me with a big weakening of the signal and especially the fact of finding it by holding the antenna between my fingers. But I'm not particular in his fields of course.
See you soon then.

Re: Mach2 Wifi problems #Mach2GTO #WiFi

 

Dominique,

 

Good to hear you were able to restore operation to the system. Also good to hear that the manual was of use! I would still be interested to know if the issue was the CP5 emitting too strongly or some type of interference, but that isn’t something I can decipher from AP. If you feel the urge to test things beyond what you have already done, I would be interested to know what the signal strength is at a couple of positions in your observatory with the antenna extended vs flat. For on the go testing, I use a free app on my phone that displays all of the WiFi signals in the area and their relative strengths, as well as the channels they are on. There are a number of apps that do the same thing, so you should be able to find ones that you enjoy for free. On Android, I have used WiFiAnalyzer and WiFi Analyzer successfully. Checking the WiFi signals in front of the CP5 and in front of your computer with the antenna up and down would show if it really was an issue of strength, or possibly some type of interference.

 

Liam

Hi Liam,
Hi All,

In my case, the problem was not that the CP5 was not emitting enough when the computer was plugged in, but that it was emitting too much with the antenna active. The new CP5 manual with the chapter TROUBLESHOOTING, TIPS AND SUPPORT gives the solution. With the antenna lying down or not but surrounded by an aluminum foil no more worries. I just tested.

Hi Ray & All,

I identified a faulty serial cable. This is even more embarrassing as I had soldered the cable myself so many years
ago following instruction from a brand new computer book (at the time) and I was so proud of the
accomplishment.

Once the cable was replaced with several other any large combination of serial extensions, USB cables,
extensions, hubs worked fine. In the end it worked with 2 serial cable extensions of about 12ft each, 2 USB
extensions of 6ft and 8ft and an unpowered hub in the middle. That's about the robustness I expect from simple
wired serial protocol. (alas USB is pretty basic serial as well)

Ray, if I may ask you one favor. With all the extensions in place I recorded one last log from the driver.

Re: AP Driver fails on serial port after PC repair

Hi Gert,

As per the prev question. Is it possible to run bench tests with the AP driver and the the GTOCP3 on a bench? What
tests can I do that way?
The AP driver does not have any built-in tests for the CP3. If the motors are not connected, the driver will probably respond to some, but not all of the commands the driver sends.

What are you hoping to accomplish?

Agreed. Long time ago the 'word on the street' was to avoid adapters with 'Prolific' chipset and use those from FTDI.
The way I see it even today these two are the dominant manufacturers of USB / serial chipset and the parts we're
buying on Amazon are all pretty generic enclosures for either of those chips. I've been going with FTDI for ages
now and have never seen an issue. Thus I'll stay with it.

Re: AP Driver fails on serial port after PC repair

Gert,

I went through the latest logs, and at least one showed good comunication to the CP3, so I don't think the problem is with your CP3.

I went through 2 shoe-boxes of USB cables / USB adapter plugs. Something there got really picky. Not sure what's
going on.
The weakest link in your setup is going to be the USB/serial converter. They are only as reliable as the driver and the components of the converter.

Most USB cables have a length restriction of about 15 feet, so it's best to find a serial/USB converter with a short pigtail. Then you can use a DB9 male-to-female serial cable from the adapter to the mount. The serial cable can be much longer than 15 feet and still maintain reliable operation.

Also, using a USB hub can cause problems, so avoid using one if you can.

Hi Ray,

Thanks for making the log-zip utility this nice small standalone package!

I went through 2 shoe-boxes of USB cables / USB adapter plugs. Something there got really picky. Not sure what's
going on.

My prev. connection (which I like) is :
Mount - 1:1 serial cable - USB adapter plug - USB pigtail extension - laptop.
The pig tail extension (2ft) is there just to strain relieve the USB connector at the computer. Not really necessary but
I like it that way.

Replacing USB adapter plug AND pig tail I got to a connection that worked. I have logs here.
http://skywatcher.space/download/AscomZip-Gert-2020-09-27-104919.zip

The last ones show a 'working' connection. 2020-09-27 02:40:24

I tried my 'old' cable setup with my older 'astro' laptop (win7) and it was OK, though more experiment is needed. It
go too late.



* Is there a B BIOS / driver setting on the PC side that controls USB OS priority that I forgot about and that has
to be re-established in the new mainboard? The board is a 100% same Dell part (alas from ebay) down to
manufacturing rev/date silk screen print.
* Is there a failure mechanism in GTOCP3 where the serial is loosing oooompf ??
* Can I debug the setup in the bench just with the GTOCP3 (no mount) to simplify thing? (What should I look
for to check connection? / I can't press the mount move buttons in the driver and check mount motion then)
* I am thinking that the USB serial should be a rock solid connection with no 'cable dependent' failure modes.
It's solid wire connection / nowhere near demanding signal frequencies / 30 year established tech)

I've mounted a new scope I have...Plane Wave 12.5. I have the scope as far forward as I want in the saddle (might be able to move it another 2" ahead). Right now I have 110lbs of CW and it still isn't perfectly balanced (probably need another 10lbs.

Is having 110lbs of CW okay? The scope with the imaging train is probably 80lbs?
