the results have show to be off.
Am I using the wrong motor?
The point is the kind of motion required.Some idea of the mechanical arrangement of the turntable is useful - direct driveto turntable from motor spindle, or belt drive or some sort?
Hi,the link is to a jewellery ad, what is rotating apart, the ring on the screen?More info please..Tom......
Yeah I know about the no no's but if only one non load servo is used it should work just fine.
If all you are doing is rotating lightweight things (rings) then a good easy way to do it would be with a "sail winch servo" which can be rotated 360 deg. It also has position control whereas a stepper would need a home switch and a driver board and a power supply to drive it.If there is no load on the servo then it could be powered possibly by the arduino (5v) with a nice cap.Yeah I know about the no no's but if only one non load servo is used it should work just fine.
You need to define the equation defining the motion you want, convert the output toa number of steps, and regularly check to see if this changes - if so you sendthe right direction of step to the motor (and keep track of where it is now) - effectivelyyou are using the stepper as a servo.
All motions would transition smoothly and not in the typical abrupt manner that a usual stepper or servo act as they are performing their instructions. I am sure this can be done, I just need a nod in the right direction to complete. Thanks for your opinions and help.
Is a "sail winch servo" the same as a "continuous rotation servo"?
