lin_guider apparently requires the firmware that Dan recommended to work. I am not sure how to resolve that conflict yet. I don't want to lose QHY support in the INDI/Ekos stack but I want my guiding to work. Jon, You mentioned that you use PHD2 to guide. I think that's where I will end up in the short run until I can figure out a way to resolve the QHY dependency on lin_guider. Would you mind walking me through your setup for you have PHD2 configured? I started down this path and actually almost had it working but I took a left somewhere when I should have taken a right I think and it all went sideways.
