servomotor - 15

  • Windell Oskay 8y

    This 12 V, one ton automotive jack has been converted in to a (very strong) hobby servo motor. The string running down from the top goes through a hole in the base of the printer and turns a pot that is used for position feedback.

    very clever idea! I've been working on making servos out of windshield wiper motors, which provide a lot of torque at nice rate of rotation (and usually they are very quiet). I'm using a pot similar to your setup, and a microcontroller to actually run the motor and communicate with the computer. I had also though of experimenting with having the uC be able to read the PWM of a typical RC receiver (like used on radio control airplanes). The funny thing is, it's cheaper for me to get the parts for a monster servo (if I use the junkyard for the motors) than to buy a tiny RC servo!

    Keep up the good work!

    All three axes of the CandyFab (well, all four, counting the heater) are controlled by microcontrollers that read in standard RC servo PWM input code, as you mention. It's quite nice.
