I am new in the platform. few days ago using a Stellarmate operating system on a raspberry 4. I try to guide with Phd and ekos app, but the axis of RA drifts towards infinity and beyond in graph. DEC move is OK. I connected my mount and cameras directly to my laptop and the guidance is OK. . It gives me the impression that it is sending pulses in the opposite direction. I moved a lot of buttons and knobs but cannot change the problem. the connection is on eq3 skywatcher mount with oem serial cable, with a generic rs232 to usb. mount moves with ekos app with no problem. also check the position (southern hemisphere), correct time utc ... etc. next week try connection wit FT232RL chip.
attach two images, from stellarmate OS and PC phd. with the same telescope and mount configuration (no changes).
I tried with the standard configuration (without changing anything), and the one I use in pdh2 on PC. Same problem happens with both config. Physical connection is by generic 340 usb adapter and OEM db9 to rj11 cable, connected to handset. V4 handset is configured with time, location and aligned with 1 star. Today arrives FTDI FT232R usb adapter (jmper selectable 3.3-5V) to connect directly, and flashed the os again.
Can you go to INDI Control Panel --> Synscan --> Guider and try to set pulses here manually? i.e. set 3000 in NORTH or SOUTH then open mount control panel and see if doing that changes the Declination value. Same thing for WEST/EAST and RA value.. do they change at all? I suspect it could be due to the synscan guiding performance within the driver itself.
