Title: need servo mod help
Post by: kurtron9000 on May 27, 2008, 11:01:43 PM
AHHH!!! So i basically I've been putting off this Mod to the very end. When I plug my servo into the servo bus and flip my battery switch on they do a quick little rotation and that is it.  When I programmed my microcontroller with everything hooked up at the completion which went surprisenly fine it did the same little rotation.  So I think I'm close to being finished the last thing is this Mod that is driving me crazy.  I bought the HiTech HS-425 BB.  When I open it up though I got totally lost.  First, do i need to reprogram my microcontroller to make it use the hex file and erase everything else.  Second when i turn the swith on with the gears out it dosen't spin freely.  And third I don't see any thing that is making it stop and even if it was it rotates in the same direction each time.  I hope all this makes sense to someone.  PLEASE HELP MEEEE!!!!! ??? ???

Hmmmm I didn't quite understand your questions.

You need to use the servo modify .hex file on your microcontroller to do the servo mod.

With the servo mod hex file loaded, and everything plugged in and turned on, you need to rotate the pot until the servo stops rotating.

Does this help?

I modded the HS-425 once upon a time

If I remember correctly there is a white plastic stopper piece on the potentiometer . Remove that to disconnect the pot from the motor . That is the easiest servo I've ever modded .
Then follow admin's gluing instructions, it gets the job done .

Take a pic of the inside if you need any help , I'll be happy to explain it and point it out in the picture.
