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 for stepper motor equipped mounts. 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 (GEM, Fork, etc.) and Alt/Az (Dobsonian, etc.) It uses an LX200 like computer command set with a few extensions to suit hand-controllerless operation.
In addition to the wide range of software supported through it's ASCOM driver, many software packages work directly with it's LX200 protocol. These include Cartes du Ciel, Stellarium, SkySafari, etc.
There are hand-controller Apps for Android and iOS devices available in the Google Play Store and Apple App Store (both are free). These allow you to Un-park or Align the mount to get going, then startup SkySafari (for example) and connect (using Bluetooth or IP) to have a full planetarium type control application... All from a cell-phone or tablet.
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 consider donating code to the project (if capable,) or perhaps a language translation, or new celestial object catalog for the SHC, or a small monetary donation which can be put toward covering my expenses associated with this project.
Howard,
just tried it with this little change to the Pins.Ramps14.h file:
#define LEDnegPin 13 \\Aux0 = 11
and it works beautifully and does no harm. It lights up the

Oh NOOOOOOOOOOO. after several Months waiting and several hours trying to understand why the program would not compile I have realized they have sent the incorrect board. they have sent a Wemos D1R2

Without cutting that trace on the Teensy the MiniPCB2 will "power up" with just the USB plugged in (5V and 3.3V become available but the motors will no run.) I.e. you will see the power LED

I will go back an look at my scratching of this connection. The location shown in the picture is unclear to me.
I was thinking the same and have gone back to that connection a number of times. Will

The heater outputs are supported in OnStep as auxiliary features, dew heaters, switching EL panels for flats, etc.
Mapping status LED's over that is not the way to go.

Should power up with just the coaxial DC connection.
Power from the USB into the Teensy should have been physically disconnected as instructed in the MiniPCB2 Wiki.

My MiniPCB2 requires both motor power connection and a usb to computer connection to power up.
Is this normal or have I missed something. MiniPCB2 and SHC working. WIFI working.
Thanks to all

if nothing is connected to the heater or fan terminals, it should not matter if the FET's get switched but the LED will turn on (if I read the schematics right). Therefore it could be

I see you trying a bunch of things to solve a problem that you alone, AFAIK, have encountered. This works for many users on many devices, the play store says my App is active on 1281 devices

Howard thank you for your immediate response!
I would like to clarify a little more on the matter: once i power up the MaxPCB, the blue led of wemos starts blinking and continues for about 30 - 40

Yes am using 0.9 degree 4.4kg.cm motor with direct drive... not dare to use pulley, because am using over 10-15 kg payload equipment.
Just order two TMC5160 V1.2 USD 12.65 for

Yes, I have plans to add PEC and Home switches. I think my guiding errors are a magnitude larger than PEC. I need to sort out mechanical issues in the drives.
It was a bit of luck but I have done
