Hello all. I am new to EZ-B. I am trying to set up a tank drive using a sabertooth 2x60 as my motor controller. I cannot figure out what configuration i need to control the motors. I have tried the serial connection in the tutorial but it will only control motor one and in only the forward direction. i have tried it in R/C mode with switch 1-off, 2-on, 3-on, 4-off, 5-on, and 6-off. using that configuration both motors start moving the second i apply power to the motor control board but i am not sending any commands to the ez-b. What other configurations can i try? i have spent the last 4 hours surfing the community and have found nothing that has worked for me. i also tried the configuration in the sabertooth manual where switch 1-off and 6-off but here as soon as i apply power motor one powers and starts moving without me giving it any commands from the EZ-B. any assistance would be very helpful. Thank you.
