![]() Needle hole is way too big, this results as same as not having foot at all (nearly).This is made for other methods, but it is still the best. It would make sense to have round hole for needle and thread. As seen on image above, lifting arm is stuffed with shrink wrap by me to maximise movement. Sliding hoop under this foot is tight fit. This is best what comes to end result, but lack movement.Embroidery pressing foot is special because it rises every time when needle is up most location. I have tested these and only one is good, not actually, but it will do on start. There are 4 types of pressing foots available nearly everywhere. If fabric rises with needle, entire stitch is lost, outcome is nothing that we like, this is of course a problem that my machine had. Pressing foot, you need one and specially designed to embroidery. If sewing machine needs some sort of uncommon needle, I recommend to get another one.It is way easier to ditch than fix on this stage. Before starting any modifications make sure sewing machine is fully working condition, use new thin needle and fabric and make long enough run.With older sewing machine there is not that many parts to go wrong and old singer types are dirt cheap, if not, just find another.Iron body makes it easier to swap more suitable stepping motor.Fabric can become really tight when plenty of sewing is being made on single spot. Cast iron body, assures there is not any flex and wind wont fly it away. ![]() It must be domestic, no walking foot or anything that sort of “helping” movement, we don’t need that.Simple straight stitch is only thing we need, so keep it simple.Build Instructions Choosing suitable sewing machineīasically anything will do, but it would suit much more better if it matched a few basic requirements: After all, embroidery machine is nothing more than overgrown sewing machine. End result should be really close to hobby level embroidery machines, just slower speed. Help and examples how to use Inkstitch extension can be found address above. It is nothing to do with medieval sorcery, it is a matter of downloading Inkscape and extension called Inkstitch Now we have movement and code, but how to make nice shapes and export to G-code. It is not that complicated and it is only carrier like any other one when going from system to another one. Synchronous movement comes from Arduino powered GRBL G-code interpreter, it is mouthful, but basically machine moves using G-code send to Arduino. Both axes use GT2 belts, nema17 steppers and both directions are fully scalable. XY movement consists mainly 3D printed parts, 12 pcs and similar parts known from self build 3D printers. It is recommended to use older sewing machine, way more convenient to mount stepper motor to cast iron and prises are relatively cheap. Only change for original is stepper motor with synchronised pulley system (chain/belt drive) and more embroidery friendly presser foot. I didn't test grbl until now, because I don't have my system working.Sewing machine part is any old or new sewing machine.

Several different tools are also available including GUIs. All tools are Open Source and available for all this platforms. It should be adaptable to Win and Mac OSX. The following description has been made for a Linux system (Ubuntu 9.10 64bit). Focus on the kind of GCode produced by CAM tools.
