Re: Initial OnstepX download error

Robert Benward
 

I just put in OnstepX, I did not touch the SWS.  I will have to reload the SWS, maybe I did something wrong...

But, I don't see current in your screen.....

Re: [Q] STMbluepill wifi & usb connection control #bluepill

Dave Schwartz
 

The Wifi module blinking 3 times followed by a pause, repeating forever indicates it is not establishing it's serial connection with the main processor. This board is designed so that SWAP is not necessary in the SWS configuration so leave it off. The baud rates on both sides should be set to the same value - I use 115200.

If tracking is enabled from the start, the green LED on the STM32 should be blinking since that is the tracking LED.

Is tracking turned on?

Hi, Background: My scope is a GSO 12" Dob that I have added 2 nema23 stepper motors to the mount which run along timing belting, one for alt and one for az. I am trialling a goto system from Byers using the OnStep firmware and I connect to the system via wifi.

Tried using the "goto" command in the OnStep app and got the "Goto failed in standby" message. I followed the solution given by a Group member previously i.e. "press the [at home (reset)] button. I had the stepper motors off the belting and they worked when I selected the "goto" command. Put the motors back onto the belting and tried the "goto" again but got the "goto failed in standby" message again. So I went through the process again of "resetting" etc and even turned the whole system off and on again. Did the "reset" again but each time I tried after this I keep getting the "goto failed in standby" message and obviously the mount doesn't move. Any suggestions.?

Darryl.

The Wiki is all organized and will help you narrow down the type of build you want to do.


This one is very popular.  With LV8729 drivers you do not need the extra wiring that the TMC drivers need on this board so it is pretty plug and play.  It is a great one to get your feet wet and learn the in/outs of an OnStep system.

Then if you want to build something from the ground up you can with the new knowledge that you have.

Hello everyone,
First things first this appears to be an amazing group with a wonderful project behind it. Second, I’m planning on making my own equatorial mount, capable of carrying around 75-80 lbs and I want to incorporate this system because I recently attempted the rDUINOScope system and my results were…not the best. So I have a lot of the components laying around and was wondering if it would be possible to make a goto scope that could be controlled through a serial port on stellarium and also have autoguiding and maybe even a motorized focuser if I’m feeling a little extra😂. I see all the posts but I’m overwhelmed and not sure where to start. Some pointers in the right direction would be greatly appreciated!
Below is a list of components I currently have:
Arduino Due
Arduino Nano
DRV8825 drivers
DS3231 RTC
Various components such as resistors, caps, regulators etc.
plenty of Vera board!

Hoping this will be a fun project!
thanks!

This picture show those light that up when power on the device.
The LED on CP2102 only always ON if not connected to computer USB port. If connected, light will go OFF after a short while.
The blue light on the D1 mini blink several time then stop about a second then blinking again.
Both LED on STM32 Bluepill are always ON. No blinking.
RA motor is rotating as set to Autostart in Config.h



Re: EQM35 Pro - replace gears with pulleys and belts #EQ5 #backlash #mount

 

One other thing...there is no reason why you need to keep the existing geared motors.  You can replace with the Stepper motors and pulleys.


Re: EQM35 Pro - replace gears with pulleys and belts #EQ5 #backlash #mount

 

This mount is a CG3/CG5 hybrid.  The DEC axis conversion works just like the CG5 as it has that appendage sticking out from where you slide the mounting plate.  The RA axis may be more difficult, but there are examples in the Showcase page.

See this post on some advice regarding this mount:

[Q] STMbluepill wifi & usb connection control #bluepill

universe24
 

I have recently built the STM bluepill v1.8.
The initial flash of OnStep into the bluepill look good. Yellow LED light up and RA motor start autotrack.

I got a D1 mini from a friend who previously built similar system. Without any further flashing this D1 mini, the wifi up with ip which not default use by OnStep. However, I was unable to connect via OnStep mobile apps.

I flash the latest WSW to the D1 mini and the wifi not show up anymore. I've tried many times and still fail.

After that, I test the OnStep ASCOM connection. The connection fail too.

But the RA motor will start autotrack whenever the system power up.

May I know what happen?

Thanks.


Re: OnStepX rotates RA only one way when connected to ASCOM

I connected my port monitor to Serial2 and setup logging:
#define DEBUG                         VERBOSE //    OFF, Use ON for background error messages only, use VERBOSE for all           Infreq
                                          //         error and status messages, use CONSOLE for VT100 debug console,
                                          //         or use PROFILER for VT100 task profiler.
#define DEBUG_SERVO                   OFF //    OFF, n. Where n=1 to 9 as the designated axis for logging servo activity.     Option
#define DEBUG_ECHO_COMMANDS           ON //    OFF, Use ON to log command/responses to the debug serial port.                Option
#define SERIAL_DEBUG               Serial2 // Serial, Use any available h/w serial port. Serial1 or Serial2, etc.              Option
#define SERIAL_DEBUG_BAUD            115200 //

I attached logs from slewing to Vega from the App and Stellarium. Do not see any issue in the log as well, I'll validate that the issue is still there tomorrow, because now it just connected to a spare ESP32 board where I uploaded same firmware.

Discovered for myself that the ASCOM driver does not set the date and time on connect by default, and (for my hardware without time source) it seems like the OnStepX recovers time from the NV/last run, which does not seem to be correct time. So I have to pay attention to have this checkbox set.


Re: Plug-in interface for External stepper Drivers

Robert Benward
 

To the diode question.  Yes and no.  For starters, the top diode is backwards.  The voltage will never go below 3V.  Series strings are useful if you want to keep a tight reign on the voltage and keep them within the supply rails.  You can use a single zener to ground, but the breakdowns tolerances are not that great, and they vary quite a bit over temperature.  You can use a regulator diode, such as an LM4040.  Those are tight tolerance, but also expensive.  For one input, OK, but if you had 20 or 50 or 100 inputs, your boss would probably fire you. 

The Schottky diodes are used for their low forward drop, insuring conduction not much higher than VSS (or 3.3V in this case).  The other half, the threat current x the voltage is a peak PD.  A 100mA threat x a 3.5V zener is a larger dissipation than the same current through a 0.3V forward drop.  This arrangement assumes you have a robust 3.3V supply (or whatever VCC you are using), and you can absorb the pulse current via all the other loads and the inherent capacitance on a supply line.

The thing is, they are unnecessary; every IC has these intrinsic body diodes built in to the substrate and across every input.  That is why absolute ratings, which used to be specified as max current into a pin, is now specified as VCC+0.3V or VEE-0.3V.  With sufficient impedance, and understanding the threat, the body diodes and 100K or an RC, is more than enough to protect the input. 

Still need to fix the input voltage though...

I have not updated my OnStepX MiniESP3 to the latest SWS yet.  I will do that tonight.

Here is what i am running now and i have the data under "advanced".

WeMos R32/CNC v3 LV8729 Focuser

Johnnie Pattison
 

So, I'm getting a new mount, and because I like Onstep so much, I decided to build a stand alone focuser for it. I have built 2 Onstep mounts with focusing and not had any issues. This time however...
I took the code from my CNCv3/LV8729 setup and started with new hardware. Set the code to track on startup, and left all Axis OFF except Focuser 1. Added an ESP WIFI module and everything works. The issue is that when I turn the focuser off, and back on, it resets to position 0. I have gone through the code of all 3 setups and can't figure out why it doesn't save the position between reboots. Fault WIFI module? 


MAXSTM3.6 Components #blackpill

Douglas Cook
 

Hi to all,

I have taken the plunge last night and ordered a bunch of MaxSTM3.6 boards. When considering UK postage, it seemed pointless just ordering a couple of them. So either i will need all of them because of screwups or more likely i will have some spare if anyone in UK interested.

Bill of Materials has also been ordered - enough for one board.

However there is one component that is proving elusive for me in the UK - its the PJ325M 3.5mm audio socket. I can find them and they are accessible if i buy 5000 or if i order Qty1 for £0.15 and then pay £30 in postage...........

Just wondering if anyone in the UK has a spare PJ325M in their back pocket........??

Probably the source code isn't installed correctly (path problem:)
Uploading the Firmware

If that doesn't do it re-install the Arduino IDE.

Just to be sure, you do upload the date/time into the OnStep controller? It's not automatic.

Hi 
I am having a bit of problem while verifying the code..
The Arduino ide is not able verify the code
The error is :

OnStep:65:10: fatal error: src/sd_drivers/Models.h: No such file or directory
   65 | #include "src/sd_drivers/Models.h"
      |          ^~~~~~~~~~~~~~~~~~~~~~~~~

But the all the path is written in the program are doing well..
But still ham getting this error..
How to tackle this issue
