Like I said in this case, there is chance involved where the correct value just happened to line up. Encoded as done for compact catalogs... Dec is +/- 5 arc-seconds. RA is +/- 10 arc-seconds. So give

#esp32

This is a compact Declination value for example... instead of using a float (4 bytes) use an 16bit int (2 bytes.) 10088/32767 = 0.3078707 (such that the full 16 bit range being +/- 32767 maps to +/- 9

Yep, I see it does that, degenerate coordinates during the transformation from Equ to Hor when right on the celestial poles. I patched OnStep release-4.24 so it handles that as a special case.

So, you're in Antarctica?

Mount type?

OnStep Version? Site Latitude?

OnStep defaults to Topocentric coordinates, which incorporate the effects of refraction. Tracking does not, by default, incorporate refraction (for good reasons.) That confuses users, you are not the

It's been a long time, but from what I see that's basically abandoned code. It's ignored. With no PEC sensor wormSensePos is always set to zero. With the PEC sensor PEC is disabled until the sense eve

It's the default, but not required. The configuration Wiki covers it.

Version?

Version 2.7.4 works fine for me, version 3 didn't work. Now see no mention of the WeMos D1 Mini's blue status LED during all of this, first and most important thing, that'll tell you if the SWS is up

The preferred regulators in the Wiki are low cost alternatives to the OKI78SR, I added mention of that other one too though, thanks.

Yes corrects for the alt/az mount not being level but for go-to only, not tracking. Next version OnStepX was designed so that the pointing model applies to tracking as well as go-to. That is still a w

Is the ST4 guide port active? Disable the port in Config.h to see if that fixes the problem.... If so, take a good look at the soldering and nearby resistor array.

We're still working on updating the Wiki for release-4.24, it now has this fix and answers your questions I believe.

That's stepper motor resonance or ringing. Lower current can help (about 50% of the motor rating,) higher voltage can help, motors with lower inductance (higher current) can help. Frequently Asked Que

I'll put that in the files section. Technically the board isn't designed for the lm7805, they usually need stabilization caps nearby. There's a 0.1uF but usually they need a 0.33uF too and the board d

We are DIY here, currently I know of no one selling complete controllers.

I guess you could issue commands like this from the Arduino Serial Monitor: Start tracking... :Te# Set rate 2 which is 1x sidereal then guide east for 2 seconds, RA axis (normally moving at 1x) should
