OnStep final installation mystery
May not have a bearing on your problem but on a different type of setup I solved a similar issue by replacing the stepper drivers. Gerry

Onstep Fine tuning
I cannot get Onstep to track properly and have encountered speeds more than twice expected tracking speeds. I wonder if you can suggest appropriate calculator and Config.h generator entries for my Dob

Chris, Yes, I had done that previously and the app retained that data which I could select and upload getting "Success" as a response. Time is set by the Android phone. If that is the Ra and Dec then

HI, Got my my Onstep FYSTETC S6 V2 functioning, to a point. A few things are not right. 1. The system is reluctant to do initialisations in daytime and I usually kick start trials by manually orientin

Basic Motors for a Dobsonian?
Martin, My apologies. Double checking my original email I found a typo and I find I'm a decimal point out on my primary ratio. For simplicity I had rounded down a figure of 38.1:1 but foolishly typed

The FYSETC is a very useful board with lots of capacity for added features although it has given me a bit of trouble. Against that, let it be said I'm not exactly an electronics genius. Suffice it to

Compilation Error: TinyGPS++???
Chris, That was among the things I tried although I think I may have left the other TinyGPSPlus library files in place. I'll temporarily rename them and try your suggestion. Gerry

Motors not reversing with Control in Sky Planetarium
Good news! The new stepper motor drivers solved the non-reversing problem and I am now able to command the motors to turn in both directions. Gerry Byrne
