Configuration of the Aux features is described in this Wiki https://onstep.groups.io/g/main/wiki/19055 (pay no attention to the name 'master' - it was written back in the day when this way of configuring aux features was new when 4.x was the master).

The S6 pinmap defines Fan0Pin, Fan1Pin and Fan2Pin for use as the FEATUREn_PIN.

If you use beta (4.x) you can configure a fan as a FEATURE in Config.h.

Alternately, you can just use BigTreeTech TMC5160 V1.2, and not add a fan at all.

OK, you posted this while I was writing my previous essay....  Still I would like to see that test I described to see if the motor shafts actually move, but if the voltage is not dropping then extend the tests to 30-60 seconds to see if we see motion.

Is it a 5V or 12V fan?  5V you can just plug it into any 5V pin on the S6.  12V may be tricky if you are going to power the S6 from a higher voltage as I am not sure if ther is a 12V regulator.  But it should be fine f you can use a 12V source.

Strange looking for us northerners to see an EQ mount laying down almost in an ALT-AZ configuration but Bogota is only 4.7 degrees north.

Congratulations!

That is good to know.

Hi guys! 

I have a 40mm pc fan to be added to my build on a S6 v2, i cant find any info in the wiki about how to add it, if i just plug it in the fan 0 slot it does nothing, i think i have to change something in my config, i need your advice thanks!!

The cases we had with not finding the include files usually involved a botched IDE configuration, or improperly extracted zip file.


See the many messages that have the topic.

Did you try with both the limit switch and home switch enabled? I'm still getting the error. Apparently they both try to use Aux3

Yeah that's not it. It just occasionally decides to forget where the include files are


Re: Robotdyn Black Pill issue

Yes, the problem with this board manager upgrade was discovered yesterday.

I plan to write a section in the Wiki about this but I was busy with tax returns today.

The result is: DO NOT UPGRADE TO THE NEW 2.x BOARD MANAGER YET!!!

As Khalid says, you will have to remove it and reinstall the 1.9.0 one.

Go back to the 1.9.0 board manager and try again.

That is a bit over my head.  not sure how the switches are working.

Re: lx200 classic (broken electro) to onStep transform #define #fysetc #S6

You can find the relevant wiring here.
For an external driver, you only need the STEP and DIR pins, and maybe the ENABLE pin too.
You can use a piece of perfboard that is the same dimensions as a StepStick, and solder in male pin headers on each side.
Insert that, and you have a way to route the above pins to where they should go.
Only the above pins need be connected to the external driver.
The rest of the pins will be not connected.


Re: lx200 classic (broken electro) to onStep transform #define #fysetc #S6

I understand. But sometimes old mounts (hand made) can be imperfect while moving and they need more power to move them. And it can be very difficult to repair them on CNC or so and just ,,raw power'' can do a job. That's the reason I\m asking. I have very old fork mount, robust, but I'm not able to repair imperfection on it and that could be handy. And I'm also interested in some schema/pic how to wire S6 to the external driver to know that, it doesn't mean that I'm ending implementing it. You know it's also the curiosity involved here ;)

And generally I'm considering that some high A applications needs those external drivers because 5160 are about 3 A max I think. And I'm also interrested how to connect them. Another advantage could be the microsteps on those drivers I think. Or am I wrong? You know, to study it first to be able to use it later when bigger scope is ready.
It is a common misconception that you need high current motors for OnStep, while most likely the opposite is true.
A well balanced optical tube does not need much torque to move.
The 1.68A NEMA 17 motor will most likely be running at only 50% of the maximum current, and will do an adequate job.
The TMC5160 have no problem doing that.

Microstepping on the TMC5160 is usually used at 1/32 or so, although it is capable of going all the way to 1/256.
What you actually use depends on the gear reduction from the motor to the final stage.
You have to balance actual physical gear reduction and microstepping. The latter is no substitude for the former.
Use the spreadsheet and enter the values you know or have.

So for the small scopes like lx200 or so I'm going to use S6 v2.0 with TMC of course and Nema 17. I already found component on inet so I'm going to purchase. This seems to be clear.  For bigger one I'll try the Nema 23. I'm also going to provide 24V power supply as mentioned before. Could you please recommend appropriate power source? 36V and step down to 28V to S6 power input?
A good and cheap source of power for OnStep is laptop power supplies. I use a 19V 4A supply for my S6, and it runs the motors, as well as a dew heater without problems.
