AstroEQ Support / Re: Using AstroEQ without a PC

Hi Pierre.
Thanks for your quick answer.
So that, according with Tom’s sentence in the link you mentioned (see below), without the need to connect a PC any time, as soon as you connect the Hand-Controller to the AstroEQ, this energizes (connect) the motors.
Am I right?

(When the hand controller is first plugged in, you must select ST-4 speed in order for it to be detected - selecting any other speed will not force the AstroEQ into standalone mode.)

Thanks again Pierre.
Best Regards.

AstroEQ Support / Using AstroEQ without a PC
« on: March 01, 2020, 16:56:08 »
Hi all.
I have observed that, once the AstroEQ is connected (via EQMOD), if I disconnect the PC, the AstroEQ keeps on running. So that, if it was at sideral speed, keeps on running at this speed.
I wonder, is it possible to start running AstroEQ (at sideral speed) without using a PC?
Thanks for your help.

Hi Tom

1-   Sorry Tom, I was not aware of these connections.
2-   Understood. Taking a look at the link about the fob, is there any chance to know the connections inside the fob with the (ATTiny10) microcontroller?
3-   Ok Tom, I have test what you said and, of course, it works.

Thanks again.

General Discussion / ST4 Port
« on: September 27, 2019, 17:09:32 »
Hi Tom
I have some questions about ST4
1-   In order to use ST4 connector, if I am right, you need to connect JP1 and JP2. What is the purpose of these JPs? Why didn’t you make the footprint of these four connections by default?
2-   On ST4 (1), what is the (IO0) for?
3-   Let say telescope is tracking at sidereal speed. If I connect JP1 (RA+) directly to GND, the telescope would go faster to west? Or do I need any other connection and/or action?
Thanks for your help and your patient.

General Discussion / Re: Skipping steps in AR Motor
« on: September 27, 2019, 16:59:56 »
Hi Victor,
Thanks a lot for your help.
As I said in my post, I do have balanced everything, but it wasn't enought.
I have changed the motor by a NEMA 17 0.9º in AR axis (I have no problem with DEC), with much more torke. I have solved the problem with skipping steps.
As I am new with EQMOM, I am testing everything, mainly autoguiding. At the end I whant to be able to take good pictures.

Thanks again Victor

Ok Tom, understood.

Thanks a lot for your help

Hi Tom.
I have some questions about the subject.
When I had an 1.8º AR motor, and I load the “EQ5-Custom Pulley.conf” file, I got the following Window (first picture). In the message area, everything seams ok.

Now I have installed an 0,9º NEMA17 AR motor. Now the AR axis moves much better than with the NEMA14 motor.
But, when I click on “update”, I get the following window (second picture) with these warning messag-es.
Tom, I don’t understand the meaning of the warnings, could you help me?
What is the “IVal”?

Thanks

AstroEQ Support / Re: First start EEPROM not responding
« on: September 20, 2019, 19:51:34 »

Hi Duncos. I am not an expert, I have started recently using AstroEQ and, as any newbie, I have got to fight with my own troubles.
By Tom’s leave, I write down some steps hopping they help with your issues. 

1-   Run astroEQ.exe
2-   Comport led blinks
3-   Select a comport
4-   Click on “update Firmware”
5-   If everything goes well, Status led should go ON
6-   If click on “NEXT”, the "AstroEQ Configuration Setup" window should appear.
8-   Click on the Folder icon and select the appropriated conf file
9-   Do the changes that you need, and click on “update”. In each axis.
10-   Click on “Done”, and the conf settings will upload to the AstroEQ.
11-   If everything goes well. EQMOD will pop up, and you should hear some kind of noise showing that motors are connected.

I hope this can help you.

Mateo

P.S. You did not need to solder the junpers, they are already made in the other side of the board (excep for the junpers to select the motor drivers)

General Discussion / AR and DEC motors move the double
« on: September 18, 2019, 00:31:53 »
Hi everyone
Yesterday my EQ5 with AstroEQ,  a NEMA14 (1.8º) and NEMA17(0.9º), was behaving well. The gotos were good enough and so the tracking.
Today, with no change that I am aware of, although the tracking is ok, the goto goes double the angle than it should, in AR and in DEC.
I am not able to find the problem. Somebody could help me

On the other hand, when I try to Calibrate with PHD2, AR axel does not move at all, so the calibration fails.
Thanks a lot

General Discussion / Skipping steps in AR Motor
« on: September 10, 2019, 17:06:26 »
Hi everyone.
I am having problems with skipping steps in AR motor.
My system is an EQ5 (brand new) and a Reflector 130/900 with only a 5 kg counterweight.
I have installed two NEMA 14 steppers motors.
Everything is balanced.
I have tried to solve the problem increasing the current limit, but as the current goes up, the problem gets better, but not enough.
I have also tried decreasing the goto speed. Again, the problem gets better but it does not disappear.  In fat even at tracking speed the AR motor skips steps, mainly when the counterweight rod is close to the horizontal position.
I have thought in changing the AR motor by a NEMA17.
Have anyone  got the same problem?
Kind regards.

Hi Tom.
Again, it took me too much time to test your advices. I have been out of home for a while.
I ordered a new set of ICs, and the communication problems are solved, but unfortunately, I can not solve the problems with skipping steps in AR motor.
My system is an EQ5 (brand new) and a Reflector 130/900 with only a 5 kg counterweight. Once everything is balanced, and as the current goes up, the problem gets better, but not enough.
I have also tried decreasing the goto speed. Again, the problem gets better but it does not disappear.  In fat even at tracking speed the AR motor skips steps, mainly when the counterweight rod is close to the horizontal position.
I have thought in opening a new thread regarding the “Skipping steps problem”, and see what others people experiences.  And also in changing the AR motor by a NEMA17.
Kind regards.

Hi Tom.
I am sorry, I have been traveling and I have not the chance to do anything with the AstroEQ until now.
The problem with the com port seams to be solved. I really don’t know how.
I tried to run the configure task again, and this time the board kept the connection for about 3 minutes, then the com port were lost.
Then I realized that I had to run first the “Update Firmware” before running the “configure”.
After running the  “Update Firmware”, the com port remains on. Then I ran the “configure”, charging the “EQ5-Custom-Pulley.conf” config file. Is this the right one?
Now, when I opened the “Cartes du Ciel”, I can connect with the Telescope (via your AstroEQ), and I can move the Telescope and do some kind of Goto.
Now I am having the problem that I miss some steps in RA, so that, the goto is not precise enough.
I have the EQ5 Skywhatcher mount, and I have bought the NEMA 14 stepper motors, and pulleys and belts you mentioned in this web side.
The torque in AR motor seams that it is not enough. According with your experience, which is the current that should be applied to the motors? I have tried with 1.5A in RA.
On the other hand, do I have to upload the config file every time I turn on the board?
Thanks Tom
Kind regards
