How to code Macanum ddrive

[whcirobotics]

The mentor suggested that we try this and we did try to get 1 victor at a time and it worked fine. Then we tried 2 at a time and it worked fine. Then i tried all together and one of it failed. So i guess it is a software problem, either that or that one is calibrated. But i doubt that it is hardware partly because of the fact that i tried again but this time i opened new project and tried writing the code and then deployed it and this time the front left one did not spin as seen in video but front right did. :S and the front left was moving for 5 seconds and then a jerk. So on and so forth. And secondly because i confirmed all the hardware things with our mentor who is electrical engineer (Mr.Thomas) and he said everything looks good except one might be calibrated. BUT if one was calibrated why did it not spin when i ran the new code, but front right one was spinning :S Something is very wrong somewhere in hardware or software :S
