Hi There, I am new to this site and am hoping you don't mind me piggy backing on this convo. If this should have been posted else where, I'm sorry and please let me know.

I just completed building the indi_servoblaster_cap driver as described in one of your previous posts knro . And I should say thank you for that post and all the documentation. I'm running Astroberry on RPi 4, and using Indi Web Manager in concert with KStars and Ekos on another comp. I have two question:

a. How can I get Indi Web Manager to see ServoBlaster as an optional driver from within the local driver drop list? It does not appear within the Auxiliary section, however it does appear when using KStars on the RPi 4, which leads me to my next question.

b. While in KStars, on the RPi 4, I can set ServoBlaster Cap as an auxiliary driver within one of my Ekos profiles and start it, no problem. However, in the subsequent Indi Control Panel, I can not get the servo to move when I click park/unpark. The servo is plugged into the GPIO pins as follows (and from what I can tell, matches your table in the previously mentioned link). Power to pin 2, Ground to pin 9, and signal to pin 11. On the Calibrate tab I choose servo ID 1, as per the table it correlates to pin 11. You should also know when I built the servo driver, I did skip the USBRelay2 Roof and Wiring PiGPIO as they were stated as being optional. Is Wiring PiGPIO required for manual operation of the dust cap or is it more for the automation within a capture sequence as describe earlier in this thread? What I'm I missing?
