Thanks DJ, I was mid-post and got called away on a family emergency. The default screen was the first and a starting point, then the next was going to be very similar to your with how the servos were acting with new settings.
When i open a panel all is ok, but a little fast. I used these setting above, on a new set up and only a SMP.

Forward button: Right wheel full speed forward, Left wheel slow reverse Left Button: Right wheel full speed forward, slow reverse Reverse button: Right wheel full speed forward, fast reverse Right button: Right wheel full speed forward, fast reverse

When i adjusted the potentiometer, i noticed one was layed back and difficult to get to, so i took it apart and noticed some silicone on the connections. So carefully moved it back into position then reassembled.

So im assuming now, my issue is because ive played with the pot, and simply need to find 0. How can i do this? Searching the forums now fora similar issue.

I actually don't know the answer to that - never have adjusted the pot before... Have you adjusted the pot on both servos?

No that was a first. I've got it back to where i was before touching them, but still have the issue of seemingly random control as i move the min and max closer to 90.

What do you mean by random control?

If the servos are back to stock (as from factory), the values that I pasted in my image will work for a slower speed.

Perhaps I am not understanding what you are doing. Are you asking to slow the servos down?

Yes, just slow things down a bit so the ping sensor can oscillate in time before moving to far a distance and have time to change direction. I just set these setting into the SMP and both servos move in the same direction, regardless of which control is selected, they just spin at different speeds depending on the direction.

The numbers do not need to be uniform. This is because a servo is not a regular DC motor. I don't think they can ever be uniform (Between forward, reverse and each side). If the pots are changed as well, it will make it more difficult to be closer to uniform values.

Instead, change each value until you get them right. It takes time, but once it is done, you're done

Certainly makes sense! Especially after getting in there with and playing around with the pots. Sort of had the blinders on trying to stay uniform.

Thanks for taking the time DJ
