In concept, an everyday sewing machine could make embroidery a snap: the operator would move the fabric around in any direction they wish while the sewing machine would take care of slapping down stitches of colored thread to create designs and filled areas. In practice though, getting good results in this way is quite a bit more complex. To aid and automate this process, [sausagePaws] has been using CNC to take care of all the necessary motion control. The result is the DIY Embroidery Machine V2 which leverages 3D printed parts and common components such as an Arduino and stepper drivers for an economical DIY solution.

It’s not shown in the photo here, but we particularly like the 3D printed sockets that are screwed into the tabletop. These hold the sewing machine’s “feet”, and allow it to be treated like a modular component that can easily be removed and used normally when needed.

The system consists of a UI running on an Android tablet, communicating over Bluetooth to an Arduino. The Arduino controls the gantry which moves the hoop (a frame that holds a section of fabric taut while it is being embroidered), while the sewing machine lays down the stitches.

[sausagePaws]’s first version worked well, but this new design really takes advantage of 3D printing as well as the increased availability of cheap and effective CNC components. It’s still a work in progress that is a bit light on design details, but you can see it all in action in the video embedded below.

A needle and thread is extremely useful if you need to fasten a few pieces of fabric or sew on a button, and a sewing machine takes things up several notches in speed an accuracy. This venerable machine, however, can now be enhanced with a trio of stepper motors under Arduino Uno GRBL control to take things to an entirely new level.

The “Self-Made Embroidery Machine” employs a setup very similar to a 3D printer or CNC router. Two steppers move the fabric around, while a third actuates the needle. This allows the user to program in decorative shapes and patterns as shown in the video below, and the build process is well documented if you’d like to build your own!

Sewing machine part is any old or new sewing machine. Only change for original is stepper motor with synchronised pulley system (chain/belt drive) and more embroidery friendly presser foot. It is recommended to use older sewing machine, way more convenient to mount stepper motor to cast iron and prices are relatively cheap.

XY movement consists mainly 3D printed parts, 12 pcs and similar parts known from self build 3D printers. Both axes use GT2 belts, NEMA 17 steppers and both directions are fully scalable.

Synchronous movement comes from Arduino powered GRBL G-code interpreter, it is mouthful, but basically machine moves using G-code send to Arduino. It is not that complicated and it is only carrier like any other one when going from system to another one.

Now we have movement and code, but how to make nice shapes and export to G-code. It is nothing to do with medieval sorcery, it is a matter of downloading Inkscape and extension called Inkstitch.

Help and examples how to use Inkstitch extension can be found address above. End result should be really close to hobby level embroidery machines, just slower speed. After all, embroidery machine is nothing more than overgrown sewing machine.

It is February of 2018. Do you remember what you were doing in December of 2012? If you’re [juppiter], you were starting your CNC Embroidery Machine which would not be completed for more than half of a decade. Results speak for themselves, but this may be the last time we see a first-generation Raspberry Pi without calling it retro.

The heart of the build is a vintage Borletti sewing machine, and if you like machinery porn, you’re going to enjoy the video after the break. The brains of the machine are an Arduino UNO filled with GRBL goodness and the Pi which is running CherryPy. For muscles, there are three Postep25 stepper drivers and corresponding NEMA 17 stepper motors.

The first two axes are for an X-Y table responsible for moving the fabric through the machine. The third axis is the flywheel. The rigidity of the fabric frame comes from its brass construction which may have been soldered at the kitchen table and supervised by a big orange cat. A rigid frame is the first ingredient in reliable results, but belt tension can’t be understated. His belt tensioning trick may not be new to you, but it was new to some of us. Italian translation may be necessary.

The skills brought together for this build were vast. There was structural soldering, part machining, a microcontroller, and motion control. The first time we heard from [juppiter] was December 2012, and it was the result of a Portable CNC Mill which likely had some influence on this creation. Between then, he also shared his quarter-gobbling arcade cabinet with us.

Have you ever come across an Internet meme and just thought to yourself, “I have to bring this into the physical world!” Well [0xb3nn] and [Knit Knit] did. They decided to take the classic nyan cat meme and bring it to life.

The frame is 24″ x 36″. Many hours went into the knitting process, but the result obviously turned out very well. The stars include 24 LED sequins to add a sparkling animation effect. These were sewn onto the back of the work using conductive thread. They are bright enough to shine through to the front where needed. These connect back to an Arduino Pro Mini 5V board.

The Arduino is also connected to a capacitive touch sensor. This allows the user to simply place their hand over the nyan cat image to start the animation. No need for physical buttons or switches to take away from the visual design. An Adafruit AudioFX sound board was used to play back a saved nyan cat theme song over a couple of speakers. The source code for this project is available on github. Be sure to watch the demo video below.
