Help a grown man stay sane!!!!
I just purchased two S3003 Futaba servos thinking I'd use them for
propulsion on a robot. I hacked them by replacing the gear with a "+"
with a brass bushing and gear from two old S148 servos, effectively
bypassing the pot without needing to hack it out. I'm trying also to
interface the servos with the Ferrettronics FT639 chip. No matter
what I do, the motor will only go one direction.
I've also tried calibrating the servos as indicated in the Robotics!
guide with no success. Also, using the pulsout command has no affect
on direction. I have been able to change the speed by increasing the
pause in the loop:
loop:
pulsout 1, 150
pause 10 <-- modifying this changes speed
goto loop
Please help!! Does anyone have any positive experience with the
FT639? What about the S3003? I've already read the tips in this group
as well as the Encoder and other sites with no success.
Thanks!

had to use some pretty high values to get a servo to go the opposite
direction before.
Later,
