I just got the latest version of Onstep. When I try to guide with PHD2, the RA jumps like a degree. Did a recent change cause this or is PHD2 messed up?

Through the kindness of John Peterson I have a working Onstep as a semi permanent loaner. Since this is my first actual working Onstep.. How should the RA tracking motor sound? I expected a tic tic ti

Sorry, a bit off topic from Onstep, but I needed a way to automate a telescope cover for a couple scopes and threw this together last week. It's still a work in progress, but the majority of the work

Finally got my OnStep setup onto the LX70 mount (EQ5 clone) last night. After setting the home position (Southern Hemisphere) I chose a star on the Western Horizon (Alnitak) to align to. This was off

I am trying to connect a DS18B20 temperature sensor to the MKS Gen-l 2.0. I have studied in pinmap of the ramps14, which this board refers, and I have not found defined in pin for "OneWirePin". I have

Hello, Howard, I had already written at other places that I can't get my AS37 encoder to run and I had the assumption that it is because of the low supply voltage. But now I took a look into the code

Dave, Update... OK now working under EQMod sim, CdC etc. Question: I can't seem to save the telescope/ mount set-up....is there a config file somewhere?? regards, -- "Astronomical Spectroscopy - The F

Hello everyone, Is there any issue when running two OnStep kits at the same time (e.g. issues with android App, WIFI server). Also is there a problem having two OnStep directories, one for 3.16 and an

Hi, I'm Just trying to get Axis4 (focuser) working and when I switch on the OnStep controller (STM32) and connect via the OnStep2 Android app, it shows the focuser position at a value of 3551um (not t

Is there a general rule of thumb for arcsec/step as a function of image scale, say k*arcsec/step = arcsec/pixel, where k is a constant? Seems like maybe k > 4 would be good, or should one use smaller

I converted my Cge Pro using a MiniPCB2 with wires soldered to the T4 to enable Gps and home and limit switches. I did this by using a custom pinmap is a real pain when updating OnStep (which I was ad

Hi Group, is it possible to build a standalone rotator controller with a arduino mega 256 and a Ramps1.4 board ? Br Klaus

I'm thinking of building an S6 version but I've read the S109 can't do mode switching on the S6 and I'm going to lose some speed. I really enjoy my 7 degrees per second slewing. Does anyone have an es

Hi , I'm using the onstep master branch with my fysetc S6 board. Every time I update the firmware I have to do a diff between the old and the new config.h files to see if there have been any changes,

Hi, new OnStep user here. I'm in the process of putting an MKS GEN L 2.1 board with LV8729 drivers and NEMA17 400 step motors to use on Skywatcher EQ5 mount. I'm using 4:1 gear reduction with belts. I

Hi, I would like to be able to turn a fan on via one of the feature options, using the outputs of the s6 board. Can It be done? . How do I associate feature1 with fan0? Can the fan speed be controlled

Just curious if anyone out there is interested in some software for real time 3D visualization of their telescope orientation? I searched around but didn't see anything. Maybe this is already out ther

Hello everyone, I have verified that only with wifi Server 1.13i the weather information from BME280 sensor is displayed. Any other version does not show it. I am using STM32 BluePill PCB (#define WEA

Researching parts to convert an Orion XT12G. StepperOnLine seems to be the recommended one. But eBay has this for $23 each. Half price. Risky? Or I can buy the two I need for the Orion, and two other
