After I built my first Arduboat (with normal thrust/steering) that went quite well, I have now set up a skid steer setup. But I just can’t solve the problems.
My Setup: Pixhawk 2.1, two T100 Thrusters with Basic ESCs, Radiolink T8fb TX/RX
Firmware: Rover beta 4.0.0-rc1 (because I need the new UTC-based delay)
Everything is set as described in the docs. Servo1 to 73, servo3 to 74, and so on. In manual mode I can drive the boat quite ok.
But when it comes to auto or acro, the boat goes like crazy. To reach a waypoint, it goes backwards first, then turning, then maybe in direction to the Wp, or maybe not. The speed is much higher than the cruise speed and wp speed.
And the strangest thing: after disarming, one thruster is still spinning slowly. I thought, disarming would cut off the motors in general?
I did read the posts regarding similar issues. Switching two of the motor connectors to reverse it and so on. Nothing solved the problem.
I uploaded the logfile of my last try (including some switching of connectors and even from left to right):
Would be really great to get some advice, I´m quite lost.
