We are having an issue with our new Bluerov Heavy, it functioned fine when in the shop pool using the builders PC - but since connecting my own PC the unit will not hold pitch in depth hold mode.
Depth hold mode functions correctly when ROV is level.
When ROV is pitched (or rolled sideways) the depth hold stops functioning as needed. For example, if pitched at 30 degrees, and forward movement input is applied, ROV will drive downwards, reverse will drive the ROV upwards, both on the 30 degree pitch. If up thrust is applied, ROV drives up but on an angle at 90 degrees to its pitch. If ROV is rolled sideways, and lateral thrust is applied, same issue. All in depth hold mode.
We know the ROV is reading depth correctly as it displays correctly and holds depth when no thrust is applied, we know GYRO is functioning as we see input when manipulating by hand.
All sensors have been calibrated, no fix.
Fathom, ROV and QGC all running latest version.
Any help or thoughts would be great!
