Re: AP Driver fails on serial port after PC repair

Ray Gralak
 

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.

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)


Cheers,
Gert

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?


Re: 900 Clutch Plug Help

Roland Christen
 


I’m calling Astro-Physics tomorrow to get some info on how to know the gears are meshed properly.
Loosen the 2 bolts. Then gently snugh one of the two to use as a pivot while the other is still loose. Gently push the motor box into mesh while simultaneously tightening the loose bolt. Finish by tightening the other bolt. That's it, you are good to go.

It is not important to have very tight mesh in RA. Gentle mesh and even slightly loose will not affect imaging or guiding performance. It is more important to not have worm gears binding. You will get much smoother performance and lowest PE with gentle mesh and even slightly loose mesh. This is true of every mount ever made.

Sean thanks for the reply.  I didn’t see your message until just now.  After a sleepless night, my wife and I started this morning and reassembled our mount.  After some trial and error we figured out how to put it back together.  We just put the motor on the RA.  I haven’t applied any electricity to the mount until I get some help with making certain the gears are meshed properly.  We only took the motor off by using the two unpainted bolts and it seemed to go back on the RA gear ok.  I’m calling Astro-Physics tomorrow to get some info on how to know the gears are meshed properly.

Hi Gert,

Changing the FTDI USB adapter improved connections but now the AP driver UI shows all coordinates at
initialization values.
None of your logs show the mount is responding, but maybe you haven't included the latest?

After a new mainboard you usually should reinstall the chipset drivers in case there are any hardware differences in the new mainboard.

Also, have you double checked power to the mount and tried a different cable?

Hi,

Following a bad charging circuit I had to replace the main board in my Dell laptop.
With that done the AP driver fails on the serial connection to the mount.
The same was working fine before.
Maybe some setting I have to re-do?

I am locking this topic since it has gone off the rails.  Ray has indicated that ASTAP will be considered for the future, but we must be sure that it is a solid product that will provide accurate information and integrate smoothly.

Re: 900 Clutch Plug Help

Sean Curry
 

Hi Bob,

I did this a few years back with my AP900 - all the clutch plugs were stuck and I disassembled it to remove them. I can't remember the exact process, but putting it back together wasn't too difficult - you shouldn't need to send it back to AP. If I remember correctly, George at AP sent me some helpful instructions, which I can't seem to find right now. One piece of advice he gave me was to keep all the Delrin rollers in a box so that the cat didn't start playing with them!

Maybe contact George and get his advice.

I might suggest that you can circumvent the entire issue of nudging the mount for centering by using plate solves and centering in a program like SGP which will quickly and easily autocenter the object you want to photograph.

Each mount requires its own calibration. Do not use one for the other. Too many variables.

Is there any reason that a guider calibration done with the Mach1 would not work with a Mach2?

Re: Guiding with a different mount

Dale Ghent
 

Yes, plenty of reasons. For one you could be correcting for backlash that does not exist on your Mach2. 

If you are using PHD2, just make a n hardware profile for the Mach2 using the profile wizard and then run it through the Guiding Assistant under the Tools menu. Apply any recommendations it has and you have your start.

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.
