I am running Astroberry Server 2.04 on an RPI 4. I have a CGEM mount, an SBIG CCD, a SX Filterwheel with and OAG and a SX Lodestar as the guide camera on the OAG. I am having difficulty with guiding calibration, I have read most of the posts on guiding and watched the tutorial. About a week ago, I performed Polar Alignment with good results and then started internal guiding and it worked well , I was able to take 10 minute subs with round stars in an F/10 setup. This has biased my judgement, that my equipment should guide well and so I have not 'studied' the reasons for success.
Since then I have not been able to repeat that success. Admittedly my PA has not been as good since then (I have a portable setup), but I do get to within a degree (or two) of the pole. Last night I tried using the guide port on the Celestron CGEM with the guide cable from the SX lodestar. I did select the SX lodestar option on the guide page (instead of CGEM mount), but I could not see any guide pulses getting thru to the mount. I watched the mount guide page for pulses and saw none.
So that is question one, how do I use the SX lodestar guide output directly into the CGEM mount guide port with EKOS internal guiding?
I switched back to guiding directly to the mount , then I could see guide pulses. I can see the guide star move when the pulses are applied and the green box moves with it, but calibration still failed. I have logs, I have tried adjusting the mounts backlash settings. I have to look into why the guide pulses are not re-establishing the position of the guide star.
Along that line, I am planning on loading PHD2 onto the RPI and trying it instead of internal guiding, I believe it has native support for the SX l.odestar. Any help in the correct process for installing PHD2 on the RPI would be appreciated. I will follow the instructions here;

unless someone has a better set of instructions.
