Hi everyone, building a rover for the first time using Cube and Sabertooth duel controller and have come against an issue With the 4.0 beta I don’t fully understand as not done a rover for a long time.
the setup is 4 motors wired left and right in pairs, Iv set the input to separate input now on the controller and set Rover to LH and RH side Motors and calibrated the RC input on the controller correctly .
testing in Manual mode I have noticed something odd in thst that’s the servo output on throttle and steering is vastly different to the calibrated RC values and it’s causing the motors to run at centre stick.
Servo 1 and 3 In skid is set as 1100 Min, 1900 Max and 1500 Trim , RC is calibrated and all looks correct on RC setup with all movements as would be expected.
At mid stick I can see the RC at 1500 or so Pwm but the output servo pwm is around 1700 or 1300 depending on if I reverse the channel and the motors are running.
To get it to centre to 1500 I have to trim the servo output to 1200 or 1800 in the servo screen to get the output to be correct at 1500 and it to not run.
Any suggestions as i can’t seem to work out why it’s got such a difference in output vs input.
