I hope the vast FIRST community can help us with this problem.
We are trying to run two van door motors at the same time using two different speed controllers
and two different pwm outputs on the controller. The problem is they run at two different speeds and cause
our arms to go out of alignment.We had them variable, running off of the same joystick ( pull back they both
go up, push forward they both go down). To solve the problem we made the joystick act like a switch
and changed the max values so they would run at the same speed, but know it is very jerky, (on off,
on off). We want to be able to be variable again but still adjust for the different speed motors. Is there a routine
that we could run in the program that could account for the difference? We know its not a friction issue just the motors
are not the same. I would like to thank you in advance for any help.
