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.
i have this stepper motor
are 2 A/phase.
If i use TMC5160 what can be the correct value for
power 12V or more?
TMC5160_VQUIET
DRIVER_IHOLD ?
DRIVER_IRUN ?
DRIVER_IGOTO ?
thanks for

First let me say that I'm glad to see you back and hope you're feeling better now.
I will investigate the issue but could you first let me know what version of OnStep. Is this 3.16 or the master?

I have been out for a time due to diseasse reasons and now im tryng to get things to work ok, also due to covid situation many parts has not arrived in time.
The controllers im making now are ESP32

So last night I did my PEC recording and playback, observing the drift in RA in PHD2 before and after and this is what I got:
As you can see, the RA is still drifting by the same amount (about 40"

You may have to estimate the end torques at the rotational axes (RA and DEC in the case of GEM) and divide by the corresponding overall gear ratios to know the motor torque requirements.

Does the Onstep keep the RA/AZ and DEC/ALT motor Drivers always on or does it execute sleep/wakeup protocols based on the need?

if i go other site to imaging i need to set new coordinate again in shc?
what if i no using SHC, how to manual key in new site coordinate in smart phone onstep?

good to see TMC5160 work great in skysafari slew very fast...but
i get error from SHC remote saying ERROR ME!
was it i set the value of:
#define AXIS1_DRIVER_MODEL

The OnStep Configuration Generator is now updated to work with 3.16 (stable) and 4.x (latest master).
This update was done because some people still struggle with the syntax of the configuration

I recently made a wireless smarthandcontroller, enabling bluetooth communication on the ESP32 controller.
I share the information to modify the original project and obtain a wireless SHC (see zip
