Servo Problems

Servo Problems- Resolved...

Good afternoon!

I just finished building a 4.2.4 Heatermeter. Most of the items are working - probes, thermocouple, blower, etc.

However, I cannot get the Tower MG90s servo working. When I first plug in the servo, it blips about 5 degrees counterclock wise, then it doesn't move again.


Here is what I've tried:

1.) I verified the pinout. Servo groud pin 4. (Brown) Servo Power pin 3 (Orange), Servo Signal (Yellow) pin 6.

2.) I checked the jack with a multimeter. I'm getting +5v on both pin 3 and pin 6. Ground is correct pin 4.

3.) I tried a second cable / second jack / and second servo.

4.) I tried a bunch of servo pulse duration settings / invert / lid mode / manual fan. It doesn't move except slightly when first plugged in.

5.) I checked the board, and could find any bridged pins or other connection issues.....

If you have ever seen this issue or have any ideas, I would really appreciate any suggestions!!

Thanks!!!!!!

Ok.....

Please disregard my previous post. I figured it out.

After checking everything over, 1 pin on the AT Mega (for the servo) folded under the chip instead of making contact in the socket.
