I am Koen. I'm a Dutch designer. My design studio is called Kim & Koen. Together with Kim we design furniture, interiors, expositions and more from reclaimed and sustainable materials. Whatever we design, I make. So here you can see how that goes.
CNC Build | The Mechanics
Welcome back to Krafted by Koen! In this video, I’m diving into the mechanics of my homemade CNC machine, focusing on installing the key components that bring this machine to life.
I'll start by mounting the gear racks, then move on to assembling the Y-carriage and Z-axis. From there, I’ll fit the gears, pinions, timing pulleys, and ballscrew, along with adding the drag chain. I’ll also assemble my custom-designed drive reduction system, which plays a crucial role in enhancing control and precision. Finally, I’ll install the closed-loop stepper motors and spindle motor, bringing the machine closer to completion.
This series offers an in-depth look at the engineering and craftsmanship involved in building this CNC machine, turning a simple frame into a fully functional piece of equipment. Whether you're a CNC enthusiast, a mechanical engineer, or just curious about the process, there’s plenty to explore and learn in this video.
To see the kinds of projects I’m planning to create with this machine, check out my website. I’ll also be documenting these projects in future videos, so be sure to subscribe, and feel free to leave a comment if you have any questions or feedback. And if you enjoyed this video, don’t forget to hit the like button!
Thank you for watching, and I’ll see you in the workshop!
This project was made possible by the "makersregeling" of the Municipality of Breda.

Link | A standing desk with wooden mechanism
มุมมอง 1.4K6 หลายเดือนก่อน
I’m excited to share this video of a unique standing desk made entirely out of wood. This isn’t just any standing desk; it’s a true piece of Dutch design crafted from reclaimed materials. The result is a functional yet aesthetically stunning desk that stands out in any workspace. The mechanism that allows the desk to transition between sitting and standing heights is a clever wooden linkage sys...
CNC Build | The Guides
มุมมอง 23K6 หลายเดือนก่อน
Welcome back to Krafted by Koen! In this video, I'm installing the linear guides on the previously built steel frame. I get to the point where the X-axis and Y-axis (the gantry) are installed and running smoothly. It's starting to look like an actual CNC machine. The idea was to build the machine so that no surfaces need to be machined or ground flat to install the linear guides properly. To ac...
CNC Build | The Frame
มุมมอง 9K6 หลายเดือนก่อน
Welcome to Krafted by Koen! Join me in this video as I take you through the process of building the frame for my homemade CNC router. Follow along as I share my journey, tips, and insights into constructing a sturdy and reliable frame for this exciting DIY project. I start by building the frame out of steel, keeping three main thoughts in mind: being able to pick it up with my pallet jack, maxi...
many good ways to solve things, thanks for sharing!
Looking so good!
Thanks!
hi there. Do you sell the plans for this build?
Hi, plans aren't done yet. I'm now working on the electronics, but can't find a lot of time. So it's a bit slow going.
Looking good! Subscribed
Thank you very much!
❤nice bro... salam from Indonesia
Amazing ❤
Thank you!
Very nice build. Everyone is building their own cnc these days lol. BTW, did you use loctite on your bearing blocks?
Thanks! I can't fit a commercial machine through my shop door 😅 So I have to. I made the frame so that I can partly disassemble it to fit through the door, should I need to move it. I did not (yet) use locktite.
Very cool
It will be a beautiful machine with the motors already equipped with an encoder... I'm drooling here...
Your Z axis looks great! It will give you a nice torque, congratulations!
Machtig !
Waiting for new episode! :D
Me too! Can't wait to have it running.
Top !
Looking good, I used a similar system with the piano wire to align my tracks when building my MechMate router. Those are interesting aluminium profiles, where did you source them? I would be interested in seeing the 3d model when you are ready to release it.
Thanks! Were you able to tension it enough? I noticed that I still got some deflection. The aluminium profile is an ISB 16x80. I got them from tech-specialist.com, but I believe it's a Belgium company.
@@KraftedByKoen the tensioning was always a challenge, especially over the long axis which on my MechMate was over 3 meters long. But once you surface the spoil board it's more than accurate enough for a wood router. Chasing 10ths of a micron is a frustrating exercise and has very little benefit.
How much do two guides like this cost? Will there be a third video?
I did go for the budget line from Almotion. The two X-axis rails (H25) were about €300, and the Y-axis (H20) €130. The bearing blocks are about €20-€30 a piece. There will be at least two more videos. 'The mechanics' and 'the electronics'. I have lost some footage which I'm trying to recover, so it takes a bit longer than expected.
Do you sell any plan or dxf file ?
I don't plan on selling plans, yet. There are a lot of people asking for the plans so I think I will make the 3D model for this machine available (for free). There are however some improvements to be made. If I make an updated version I would maybe sell plans for that. Is that something you would be interested in?
@@KraftedByKoen Yes
Hi! Do you have plans available? For this frame and for the laser cut parts? What stepper motors will you use?
Hi, thank you for your comment. I don't have plans yet, but I may make them. Also I think I wil publish a 3D model somewhere. When I do, I wil share a link to the files, here or on my blog thread: www.cnczone.com/forums/showthread.php?t=469872&referrerid=873563 As for the motors. I will be using NEMA34 Closed-loop steppers from StepperOnline.
Thank for fast response… maybe I will wait for your plans :) What will be the working area of this cnc?
it will be slightly larger than a full 4x8 sheet, with some room for a vertical area as well. I will measure the final work area.
very well done. Is there a list of all (machined) items for the frame avialable? e.g. what kind of source material: rectangular tubes, wall thickness, lenght. Thank you
Hi, thank you for your comment. I made a post on cnczone. Here you can find the cut list. www.cnczone.com/forums/showthread.php?t=469872&referrerid=873563
Ok🎉🎉🎉
Leuke bouw, top. Bedankt 👍
Bedankt voor je reactie! Het vervolg is in de maak.
@@KraftedByKoen heb hier n lowrider 3 staan, maar wil n sterkere gaan maken volledig van nul. Bedankt voor de inspiratie. 🙏
ok
🔥🔥🔥🔥
Hello, thank you for sharing. I like your way of directing and we see that there is little room for improvisation. The chassis is very sturdy and the squaring is well done, looking forward to seeing the rest and the beautiful evolution of this machine. I can only wish you the success of the project especially as it is off to a very good start ^^
Cool looking, but not very practical and useful 👎🤷
Thanks! It's a commissioned piece, so it's not meant for everybody. It's specifically tailored to the needs and uses of the client.
That is looking really good! What motors are you going to use? And by the way, a wise man once told me "if you can`t make it perfectly straight, make it adjustable"!
Thanks! And those are words to live by 🙌 For X and Y I'm going to use Closed loop, NEMA 34, stepper motors with a rack and pinion system. The Z-axis will be a NEMA 23 stepper with a ball screw.
@@KraftedByKoen I am really looking forward to see future videos of you build! I like your frame design!!
