Re: Need help with O-scope

I have had a ton of problems with my Gecko's. Best thing I
did was to run ALL 3 Gecko power supply grounds back
to a single point ground. I also use this single point ground
for my encoders ground, VFD ground, all my shields go there, etc.
You need to make sure your encoder wires are shielded and kept away
from the PWM out to the servos. Of course, this assume you are
using servos.
