Modifying HS-475HB for continuous rotation problem
« on: January 06, 2009, 12:36:17 PM »
Hello,

I followed the tutorial about modifying servos for continuous rotation but when I finished the tutorial it seems the servo is not working correctly.  After adjusting the pot until the servo stopped spinning, I glued the pot in place by putting a drop of superglue on the pot. After letting it dry I plugged the servo in to check that it spins correctly and it just hums.  I have tried several different channels (i.e. center position sticks and free position sticks) on my transmitter.  I also checked the receiver battery voltage and it is fine.  The last thing I checked was to make sure none of the glue ran into the gear next to the pot and it did not.  It seems the motor just won't spin now that I have moved and glued the pot.  Any help would be appreciated.

My last idea to fix it is to use some superglue debonder to free the pot but I want to make sure that won't be harmful to the potentiometer.  I am sure any liquid dripping onto the circuit board would be bad.

Thanks

Stefan

I was hoping not to modify the electronics as this servo has the capability of decoupling from potentiometer by removing the gear insert.

Did you get it to work?

What program were you using to make the servo rotate (after modifying it)?

Yes I got it to work.  I ended up having a damaged gear so i replaced it.  Currently I am not using a program, I am just using a mix on my RC transmitter to get dual motor steering.  I am planning on purchasing a BotBoard soon to play with.
