I don't know specifically about the MiniESP3 (it is a custom board which someone designed). You need to check
either with the designer or the schematic for maximum current and such.

But usually, any other board can be powered from 19V, and 3.5A is usually enough for two motors (or three)
plus WiFi, plus whatever the board itself requires (which is not much anyway).

I use a laptop power supply myself which is 19V and maybe 4A. Much better than just 12V power.
Works well on a Blue Pill as well as S6.

That is no longer necessary on 4.24, provided that the location and time have been entered.
OnStep detects that you have a valid location (which is not the default 0 latitude and 0 longitude),
and a valid time (the Blue Pill has an RTC that provides it), and responds like commercial mounts
when given a goto command.

Generic F401CE,
Just noticed this... the support isn't designed for a "Generic F401CE" board.

It's for the "BlackPill F401CC" and very likely the smaller memory of a CC vs. a CE makes no difference (as even 256KB is more than we use.)

I solved my problem by cutting the enable pin of the axis1 driver and jumping it to axis2. Enable pin on Axis 1 was stuck high.


Swapping Axis 1 and Focusser on FysETC S6 V2 (X is damaged it seems) #fysetc #S6 #configuration

hendrik
 

Hi there, 

i received a second Fysetc S6 V2 board today, wanting to replicate my first build with 5160 drivers. Everything went fine till i tried to turn the motors for the first time.
Y axis (axis 2) on the board works fine, X axis (Axis 1) does nothing at all, no hold current nada. 
- Tried so far: Swapping leads to steppers, leads are fine also checked them on my second driver
- Swapping drivers: Tried 4 of them now, X always the one that does nothing
- Measure pins to stepper to the stepper driver, has continuity
- check if enable etc get to the microcontroller, also seems fine. 
- Build / config is the same as for my working controller so that should be fine

So i am assuming i have a DOA board, which kind of sucks. 

My plan now was to swap the AXIS1 and the focuser 2 outputs since i don't use that port anyway, and check if that works. But i cant for the life of me figure out how the pin mapping works. 
Is there anyone with more knowledge about the fysetc S6 V2 mapping that is willing to help me out? I have looked at it for more then an hour and am afraid to ruin even more :)

That stuff is pretty cool... $8 a foot on this 8conductor 24awg one!  :)  Pretty expensive stuff.  


Where are their leftover scrap pile cables that I can pick through?  :)

Not really enough information to know for sure but I can state that with Arduino 1.8.15 and STM32duino version 1.9.0 (etc. per the Wiki) OnStep release-4.24 compiles successfully for me (with a run of the mill Config.h TMC2130's etc.) targeting the MaxSTM pinmap and STM32F401.

Kahlid, is a power supply from a laptop suitable for powering the MINIESP3?  Its rated output is 19v at 3.5 amps.  I will be powering 2 stepper motors at 0.8 amps each.

The majority of OnStep designs are stepper motor open loop, and therefore, there is no
feedback from independent movements. In other words, if you add slo-mo directly to
the gear shaft, OnStep will lose where it is pointing, and will be inaccurate.

One way of overcoming this is to add encoders that give feedback to OnStep via the
Wemos WiFi module. However, this involves extra complexity (more wires, aligning the
encoders with the shafts, ...etc).


Re: STM32F401ce BlackPill

Seems to be a lot related to errors in your config.h file which you did not attach (except for the missing Adafruit BME280 library which you install with the IDE library manager).

mySQM+

Chad Gray
 

I messed up a PCB order and uploaded the same Gerber file twice... so now i have like 8 extra PCBs for a mySQM+
https://sourceforge.net/projects/mysqmproesp32/

If anyone wants one send me a pre-paid shipping label and i will send you one.

DM me or email me to keep this off the list.  I will be posting to cloudy nights also, but i figured this list would be more willing to build such a project.

Re: Blue pill on astroberry

James Lancaster
 

Make sure either you start alignment or turn on tracking. There's a message in the INDI control panel if it's not, as it won't move normally without that. (There are some options in OnStep that can be set to change that, but that's not normally the case.)

Re: Indi LX 200 OnStep

Khalid Baheyeldin
 

Here is a screen shot of my INDI panel.

INDI requires port 9998, because it is a persistent connection.
When you use 9999, OnStep terminates the connection after every command.
The Android app knows how to handle this, but INDI (and Stellarium Mobile Plus and Sky Safari Pro) don't.
They assume the connection will stay open to accept future commands.
Port 9998 provides exactly that.


Re: Indi LX 200 OnStep

Chad Gray
 

I recently switched to wifi instead of bluetooth and did not know it was 9998.  Isnt the Android app 9999?

Crap... well I might get some telescope time tonight... ARG!  I have been beating my head on this for days.

Thanks Khalid... i will test more, but having the right port sure would be a good first step!

So the issue is not on the OnStep side of things.
The status page in INDI is based on the output of :GU.

Maybe it is baud rate?
