Questions on Parallax Continous Servo's
Hello All!
···· I have 2 projects that·requires·one Parallax Continous Servo for each project!
Project 1
··· Is it possible to use this servo to turn Both ways·with a·limited 10 turns at 1 degree increments with a BS2? And to log the Current Servo Setting to memory so the position is known, and can be recalled·at·any later time?
Project 2
··· Is it possible to use this servo to turn both ways but a limited 300 degrees? (Less than 1 revolution) and at 1 degree increments? ( I don't want to use the Parallax Standard Servo because of the need for continous pulses to maintain position and position jitter!) Could this position also be logged to memory to be referrenced later?
Thanks for reading my post!

Project 2 -- No.
You probably would be better off with stepper morors and gears.

····· Appreciate the suggestion! I will read on Stepper Motors and see if it fits the bill! Seasons Greetings to U too!

···· Thanks for your thoughts! I've used rotation counters on Ham radio Stuff!
It appears my thoughts on this Servo subject aren't anything like another method I'm presently using! Sounds like it's time to·scrap these ideas! Thanks to all that replied!

You could also modify a servo by replacing the standard pot with a multi turn pot.
However, as far as ten turns with one degree increments - no. That would be 3,600 unique positions. If you used a servo that worked with .500mS to 2.500mS pulse widths (typical is 1.000mS to 2.000mS) AND the servo had a dead band of only 1uS (typical is 4uS to 6uS) that would still only be, at best, 1,000 discrete positions.

···· Thanks so much for showing and explaining to me about the servo's!
I now see that i can't do either project with a Servo! Seasons greetings to you too!

If you were going to do this with just a Basic Stamp then you could get an encoder and move slow enough that you don't miss counts. If you have no other tasks while moving you could continuously read the encoder and keep up at a reasonable speed. For example if you had an overhead maximum of a 2ms servo pulse plus 2ms worst case of reading encoder and updating position counter, you could count 250 degrees per second.

···· Thanks for the post! Seasons Greetings!
For all readers at this point, I will NOT be answering anyone anymore as this is not a good way to do what I wanted to do!
So no more posts Please, as I can't delete this Topic! Thanks to all!
