Re: [FTC]: LABView Servo Problem

From what I can gather from the thumbnail (the .vi would be more helpful) is that you are scaling the values from the left side and right side of the second controller (either x or y) - which is correct and the left side is controlling one servo and the right side is controlling the other servo (servo #1 and #2 I believe). Is that summary correct?

If it is, it appears that the code is correct. So, let's look at the hardware. Is your 12VDC battery fully charged? Is there any kind of load that you are putting on the servos to stop them from turning? Are the two servos controlling one item and are they facing the same direction? If they are facing each other and connected to move a single arm or something, then they would be fighting each other?

If none of those answers lead to a solution, I would redownload the program to the brick and try again. If that doesn't work, then I would reinstall the firmware, redownload the program, and try again. I know that doesn't make sense, but it might just clear it out.

Good luck and let us know how it goes.
