270 degree servo won't turn further than 180 degrees

Help
1

I bought 270 degree 9imod DS35MG-270 servo and it won’t turn more than 180 degrees. Using esp 32 devkit, is there anything special to turn that servo 270 degrees? Using that servo for twist.

I had the same problem and the issue was the servos werent 270 as advetised

You had exactly the same model and it didn’t turn further than 180 degrees right?

Hi mscwot,

Try these fixes:

  • Reset your .ino file to the original: try SR6_Alpha4_ESP32 by TempestMax using the 2.0.6 espressif systems package.

  • Reduce the Main and Pitch servo frequencies to 100hz and don’t change the others from 50hz.

In addition flash the system using a 115200 baud rate, make sure your COM port in device manager matches

Well it didn’t help still turns 180 degrees

When you move the slider in MFP from 0 to 100 is it turning during the whole way or does it stop around 70%?

7

In khrull FW turned slider all the way and still 180 degrees, don’t know how to give it manual commands in MFP

8

okay figured it out in serial in MFP still 180 degrees

When you move the R0 slider from 0-100 in MFP does it constantly move throughout 0>100 with the total range being 180* of does it stop suddenly around 70% or 30%?

If it is moving constantly throughout it is either

    1. Your servo is 180* and not 270*
    1. You are being limited somewhere in your firmware/ packages

If the servo is spining fine but stops around 70% or 30%

    1. Your frequencies are not set correctly and it’s causing some type of bug

You can also try changing the GPIO to another pin to rule out hardware issues.

Try asking in the TempestMAX discord, there are a few more people who could assist you there!

Good luck!

well i consulted on discord and it seems that the seller needs to plug in and reprogram the servo to 270 degrees (still not a 100% anwser)
