You can fix this by swapping the pwms on the left side with those on the right. (either through code or switching the pwm cables). However this will make what is now the front, the back and the back is now the front. I think if you swap what's inside the limit_mix function with the one below it, then it'll fix it without changing what's front or back.

Maybe post Your code?

Ouch!

In my defense (meager as can be) I can only say I did put it inside the Limit_Mix() function, so that the function did keep the numbers in range. I'll have to check my spreadsheet numbers again, and try the 132 center point.

This is easier.

left_motor = speed - turn_rate;
right_motor = speed + turn_rate;

Where speed and turn_rate are signed char's (subtract 127 from a u-char) and left and right motor are limited to (-128,127).
