Bicep Stepper

Bicep Stepper by lothar22 Feb 13, 2013

Description

Derivatives for servoholderV1, PistonanticlockV1 and PistonbaseantiV1.stl for using a stepper motor instead of a servo.
Changed the pitch of the screw, as it was too steep for the stepper.

The Gertboard manual can guide you for connections to the Pi and installation of the Arduino IDE, so you can program it. See the link for product info and manual. http://www.newark.com/gertboard/gertboard/atmega328-assembled-gertboard/dp/46W9829

Instructions

Print stepperholder and StepperPistonbase at normal infill. I use 20%. Print stepperdrive at 100% infill.
No support needed.

hi I looked at your design and I really enjoyed it. because I do not have the opportunity to buy HITEc-805bb in Russia do not send a good replacement. not prompt what model you used the stepper motor, and how to join the Arduino

I use NEMA 17 steppers, same as I use on my Prusa 3D printer. I connect to the "Arduino" chip with a Raspberry Pi and a Gertboard (an Atmel ATmega "Arduino" chip is on the Gertboard).

Updated the stepper holder...

Wow nice! I would love to see a video when ready on software. Did you gain or lose, when the arm is totally retracted? You say you are going to limit the extension, so I would guess you gained retraction. What stepper Nema did you use?

Didn't lose or gain anything on retraction. Just can't extend fully, but it's not much at all, maybe a few degrees.

Still working on the software. My mad scientist friend is coding it from the ground up. He built the printer board from scratch, starting with an ARM microcontroller and a breadboard. Steppers are NEMA 17.

Sweet! I was just thinking about using steppers in some places when I finish my printer and start working on my own inMoov build.
