This (gray) part inroduces additional elasticity which worsens the quality for larger hoops and/or faster stitching speeds. The disadvantage of this is that a part connecting the belts on the underside to the linear rail on the top is necessary (Belt_to_block.STL). The thought behind this was that the fabric will not interfere with or jam the belts. Note that I flipped the frame such that the timing belts are on the underside of the frame. The coreXY frame is suspended on four holders which bring the frame up to the required height (contained in the 3D files). On the other hand the framed design allows for a smaller overall footprint of the machine. I think I would prefer markol's approach now because the fabric of what you are emboidering can jam the gantry of Lehavier's frame if it gets between the axes. I used the frame by Lehavier mainly because I started with this and I was not aware of markol's project by then. A coreXY architecture is beneficial because it keeps the moving gantry lightweight and the motors out of the way. In the following I will adopt the sections as they were in markol's blog.įor the mechanics you basically need to build a plotter. The microcontroller coordinating everything including the UART interface to the computer.The sensing of the sewing machine's speed and position.The high voltage driving circuit for the motor of the sewing machine.The XY gantry for the hoop movement and driving of the associated stepper motors.The project can be roughly divided into four areas: His implementation allows for fast stitching and uses the machine's built in motor. Have as much of the sensors and wiring hidden inside the machine for a clean lookĪfter some searching I found the website of markol with his take on building an embroidery machine.Embroider at speeds above 400 stitches/minute.When I then could get hold of a beautiful old BERNINA 732 for free I had to start this project.There are quite some open source projects for DIY embroidery machines to choose from. Attempt this project only atyour own responsibility and use this article for entertainment purposes only rather than for education.Īn embroidery machine has been on my bucket list for quite some time because it would complement my sewing projects quite nicely. If you lack proper certification and/or experience to handle such voltages do not attempt this project in the way it is presented. The original project uses circuits that work with mains voltage which can be lethal. This article is an addition to the tutorial by markol. What is this article NOT ? A step-by-step tutorial on how to build this machine. If you you are using a BERNINA 730/731/732 you will also be able to profit of all the 3D files. So whom is this article for? For people following markol's tutorial and looking for some additional inspiration. peope using the popular GRBL shield for Arduino since this way the PCB work gets simpler and more approachable.Īdditionally I will mention details which I had to find workarounds for or which made my life harder such that you may have a little bit less debugging to do.people using the same or a similar sewing machine like mine.Still I think that the documentation of my take on his project might be useful for His documentation is amazing and sufficient to realize an embroidery machine. The goal of this article is to document my approach or my realization of markol's project Embroiderino.
