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.
