Designed this bracket to combine four Stepper Motor Driver v3.3 together in One convenient plate. Perfect for custom mounting on your 3D Printer. Mounting hole are 1/4 inch. Perfect for a flush finish on your printer!

Sometimes you want to be able to quickly disable a stepper without having to shut down your bot to unplug it. This is especially useful - although by no means limited to - when using a stepper extruder. It's nice to be able to flip a switch and spin your gears by hand.

Photos from my DUAL-STEPPER setup ( thingiverse.com/thing:6362 ); this is connected to allow me to turn off the second stepper and only use one. I built it so I could do some tests and see what difference the second stepper makes. You don't need to be using dual steppers for this to be useful for you, though.

Thanks to Kliment (and everyone) on #reprap IRC Freenode for the idea.

There's not any files or printed parts required to do this, but just for fun I designed a parametric switch cover to use for the purpose.

UNTESTED- Single sided stepper driver based on TB6560. This isn't ready for prime time yet, but it might be a good start point for someone.

**Untested project for the MakerBot Giveaway contest. I’ve got no clue about how sturdy MakerBot printed parts are, this means that I don’t know if the parts I designed are thick enough to support the weight of the camera and steppers. I’m maybe plain wrong ! However, parts size have been carefully designed to fit into Makerbot’s build envelope. The only overhangs are holes, therefore the parts should be printable on a MakerBot (At least, I hope !). STL parts have been checked with Netfabb and are manifold EDIT:I reuploaded the STL parts. They are now oriented in build direction**

This half automatic pano head has been designed to take pictures using a Canon Powershot A560 compact digital camera. The purpose is to shoot panoramas without getting into the risk of forgetting to take THE PICTURE absolutely needed to get a complete panorama (when you don’t have got a wide angle lens, you need to take a lot of pictures!)... The head moves left/right and up/down. Two NEMA 17 sized stepper motors are controlled by an Arduino (or compatible clone) using two Sparkfun's Easydriver. The shutting mecanism will be controlled by Arduino.

The Canon Powershot’s normally don’t have remote shutting capabilities. Fortunately, a great open source software package can add a lot of functionalities to these cameras: CHDK. It adds remote shutting by detecting when voltage is applied on camera usb port.
This head has to be mounted on a standard tripod.
Function: When pressing the start/stop button, the camera will take a picture (or more, if CHDK “bracketing in continuous mode” is checked – needed for HDR), then moves upward, takes a picture,… , then moves left,then moves downwards, takes a picture, … ,and it does the same column after column. When the necessary pictures have been taken, the photograph has to press the start/stop button. After, the reset button has to be pressed to put the pano head back in starting position (only horizontal axis needs to be moved).

Advantages of this design:
-No need to carry a notebook to control this head.
-Simple to use.

drawbacks of this design:
- the row/column intervals and time between moves can only be changed by editing the arduino sketch.
- No care taken about “No-parallax point” for now.

This is an unfinished rotor gear for a printable stepper motor that I am designing, I have posted this here in hopes of finding out if this part is indeed printable.

This is a circuit for driving bipolar stepper motor drivers. More information on the RepRap site: make.rrrf.org/smd-1.2
