Since I aquired an Losmandy G11 mount without any goto provision I decided to create my own solution. I was a bit reluctant to use a Gemini, mainly because of the cost, but also due to the reliability since the servo motors are somewhat prone to failure. I also like to have complete control over the software/firmware so that no "show stopper" issues will ever be a problem for me. Looking around the 'net I saw other goto systems that seemed capable, but either they had needlessly complex hardware or were commercial systems that cost about twice what they should.
OnStep is a computerized goto system, usually for stepper motor equipped mounts though any step/dir interface motor driver (including servo) should work. It was designed, from the beginning, as a more or less general purpose system and provisions were made in the firmware to allow for use on a variety of mounts including Equatorial and Alt/Az (GEM, Fork, Dobsonian, etc.) It uses an LX200 like computer command set with a few extensions to suit hand controller-less operation.
There's a telescope hand controller App for Android (free in the Google Play Store,) an option to control through a website (Smart Web Server,) and a dedicated physical hand controller (Smart Hand Controller.) Or, on a PC there's ASCOM and INDI drivers for control. These options allow you to setup and control OnStep using a wide range of software including my Sky Planetarium, Cartes du Ciel, Stellarium, SkySafari, KStars, PHD2, etc. You can see most of the control possibilities in the diagram below:
Also, please visit my StellarJourney.comsite for updates, links toOnStep resources, my other astronomy software, or to see someImages taken with the assistance of my OnStep operated mounts.
If you find OnStep useful and would like to show your appreciation and support please consider making asmall monetary donation. This keeps me motivated and helps cover expenses associated with my projects.

There was a recent thread about SWS and Ethernet, and it turned out that in Ethernet
the web interface is not fully implemented yet.
Howard forked it here and that fork seemed to work.

Mike,
I just grabbed 4.24 from Github and flashed it. I get the same behavior as before as described in the first post on this topic. Something else is amiss.

Hello Ken,
I used screw terminals on the board. Had tested extra previously whether the cables fit into the terminals.
Then have used an 8-pin RJ45 cable and switched 2 cable to contact.

To Mark's point most of the controllers used with 24 and 48 steppers used in the TruTrac and Vixen DD systems are limited to 16 or 32X speeds.
Many Vixen owners ask me if they can use OnStep goto

Hi Martin, OnStep 5.xx was not finished and is abandoned in favor of the new, completely redesigned OnStepX, which be a few more months before it's ready. The recommended latest stable version is 4.24

Pour l'instant je laisse les paramètres que Mark a donné.
J'ai modifié AXIS1_DRIVER_REVERSE OFF sur ON
Faut-il faire pareil pour AXIS1_ENC_REVERSE OFF le mettre sur ON?

The main appeal of the TMC drivers (at least the 2130 and 5160 models) is SPI control and silent operation. A 3D printer with 5 steppers running at "slew rate" speeds can be quite noisy. Of course our

I never followed that scheme. My goal was to just have 2 motors with mode switching, and Bluetooth (from the Wemos, for the Android client on a cell phone or Galaxy Tab A as remote control) and leave

Je revient sur ce que j'ai dit car je n'ai pas vu que les paramètres étaient déjà mis dans le config.h de Mark.
Effectivement les rapport ne sont pas identiques entre l'axe 1 et l'axe
