DEC Offset homing wrong direction

Open iThom96 opened this issue 11 months ago • 3 comments

Here's what I do:

  1. Power on the tracker with DEC pitched down
  2. Manually rotate DEC to home position (up) - DEC steps in OATControl increase to a positive value
  3. Set DEC home offset in settings
  4. Power the tracker off and on.
  5. Run DEC offset homing in OATControl
  6. DEC moves down instead of up

I live in the northen hemisphere, the DEC axis is inverted in OAT Firmware config. I'm connecting to OAT using ASCOM driver, not directly via the COM port

Please specify the firmware version you are using

OATControl V1.1.7.0 OpenAstroTracker-Firmware V1.13.11 (commit 693cbaa) Everything else is probably the latest version, installed in the last 2 days

I have also verified that when slewing the mount down, the DEC steps value changes to a negative value.

After saving that as the offset, resetting the mount and performing the DEC homing, the DEC tilts up, so its reversed in both cases
