I have a modified servo that is only spinning in one direction. Example, click forward, it rotates clockwise at one speed, then reverse, spins clockwise at a slower speed.,
Ive tried both a modified servo, and MS movement panel, as well as different ports, and releasing.
Any thought?
The adjustment screw is not for changing the speed. The adjustment screw is for adjusting the nuteral (stop) position.
To adjust the speed, change the settings in the movement panel.
Lets say i wanted half the speed that they are set OEM, how would i set them?
No matter what i try, i can get it, i get random results
RW Forward Ive tried setting to 120 and RW Reverse to 60.
Ive tried reversing the values, ive tried matching them. Pretty much every combo you can imagine, but nothing consistent.
1) locate free ports on your EZ-B
2) connect the plugs from the servo to the two free ports of your ez-b. One for the left, and one for the right servo. Take notice to the polarity of the plugs. The GND is the black pins. Power is the RED pins.
3) make note of what ports you connected them too
4) visit the configuration dialog for Modified servo Movement Panel, such as you have screen shotted
5) Click on the ports (currently where they say NA) and select the ports for your modified servos that you have connected to in step #2
*Note: when you press the button to select a port, a dialog will show you a picture of the ez-b. For more information, you can visit the LEARN section
I use these values for the Rider robot - which you can find in the EZ-Cloud AppStore...
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.
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?
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.
Instead, change each value until you get them right. It takes time, but once it is done, you're done
Thanks for taking the time DJ
