I know this is an old video now at the time I'm comenting however still worth a mention for anyone who might come accross this. Instead of turning the ballscrew which is a large mass, rotate the ballscrew nut and have a fixed screw. I think having something like hgr15 or 20 guide rails fixed directly to the side of the table would be worth while considering for something of this size also. Would simplify the build and eliminate the problem of that flex in the y axis.

Very Nice build. What most people do not realise is that there needs to be a table. That is maybe the first consideration before getting into the machine building part. In your case take into consideration that the Spindle motor is going to get HOT which means that the 3D printed part will become soft and therefore you will experiance Z movement on spindle. I would use aluminium clamps for the required spindle - they are freely available now days.

Is this build alive after 3 years? It is very interesting. Did you have horisontal deformation on the long side?

The title should be how to cut paper.

@2:30 those are just 5 pentagons... @5:18 oh, there it is! :D

Guessing it didn't work....? Cant find the 3rd video.

In the Y-axis long tubes, you can probably insert a vertical plate inside through the corners to give it more stiffness. Or even a round aluminum tube that is a tight fit but then there is that annoying weld seam inside the square tubing. I don't know how much that would improve the sagging. But your idea was great with rolling support.

I'm building a Root4 in half the size as yours, using 1600x1600mm ball screws. Should be stiff enough. I was hoping to see your video of the electronics being hooked up. Did you not record or upload that step? Regardless, your 2nd video in this series, assembling the X and Y axis' was extremely helpful. Thank you very much for sharing that. Well done and I hope to continue seeing more videos from you.

This is a bit more professional looking than the one I made but the principle is the same. I 3d printed the rail fixing and the sliding stop but, being a cheapskate, I used plywood strip (about 75mm wide) in place of the t track and for the measuring tape I used the paper tape measures that hang up in a well known swedish furniture retailer. Not as good as yours but, when I inevitably stand on them, I won't be heartbroken at having to replace them. Good video, thanks.

Great job so far my friend.. I would love to have the space to build one this big but mine is going to be 1200x1000mm ish.. LOL I love the way u built the CNC printed parts fro the runners along the Y-Axis.. I'm using 2060 extrusions for my Y-Axis. I bought pre assembled runners from Amazon with the V-slot wheels already on them but I'm struggling with the Gantry parts atm. What is the width of the Plywood ur using my bro? Is it 18mm or 25mm?? for ur gantry parts.. The same for the Z-Axis if u don;t mind me asking? Why the Torsion box method?? Is that so u get a completely flat surface bcos it's a great idea. I might try that myself now. I'm in the middle of getting ready to build my own table saw too btw. I have a loada steel 40x40mm Sq tubing 1000mm length. I have 25x25mm x 1000mm and 50x25mm x 1000mm sections also..I'm thinking of maybe changing tack and building a CNC plasma cutter from the steel. Won't be huge but big enough toi cut what I need and that's good enough for me.. I'm in 3-4 minds atm mate.. My brain is going 90 to the dozen right now with different ideas for so many different builds. I need to slow down and build one at a time.. LMAO U have built a brilliant CNC machine there. I sub'd liked and shared the video my bro,, Keep up the great work too btw. I'll be watching for more of this awesome content.. Salute from Dublin, IRE..

Thanks man❤

Well done!

did you ever get thru with this?

What motherboard you use?and stepmotor +driver

What would it look like if you made the pentagrams with equalladeral triangles like the yellow? Basically all yellow.

exelente

That’s literally my old school st marys

if i need to make one with a diameter of 6 meters in a 1:50 scale, what will the measurements be?

hi, dead project?

Update?

Do you have a version for non metric tube?

POV: most of the people leave this vedio after watching 0:11 ☹️😅

Unsupported rails like you have (not to mention you have no linear proper stiff linear rails) will have a lot of trouble cutting in the center of the work area. The supports you made will only help with force from the top down but none of the other directions. You may wanna look a the print NC for some inspiration for a stiff and cheap construction.

Magnificent! There would be a conversion for zipper girdle and not screw thread???

Not working or why no update since over one year?

I like your idea's, brilliant fixes. I would suggest once the machine is done, cnc all your plastic parts in aluminum. Even the x and y holders where the square beam is in changing those to steel or aluminum will do a huge difference in vibration and tensility. Other than that excellent build man.

What cnc software are you useing For your tablecan you showe use a dimistation

Put a half inch pvc inside a one inch pvc. Put it about 1/2inch above the bottom of the 1 inch. I can get 72 gals a day out of a 2" pipe 30feet down. Simplest design ever.

HOw's that coming along? Any updates?

Forced me to buy a 3d printer along with a track saw, but I need to make some custom cabinets, most local stores are out of stock and most woodworkers don't seem to want to make it, so I will do it myself.

Your cable/drag chain is twice as long as it needs to be 😉 Also, it's been a year! How's the thing working?

Hi Jamie, you did some very nice work! At the moment I am also building a large version of the Root CNC 4. would it be possible to share your 3d printed parts? it would be my great pleasure. greetings and good luck!

what are the measurements

Where is video with PrintNC

very nice. good dome mate

Hi Jamie, I really enjoyed the video and subbed. Would there be any merit in making extensions for these do you recon as I guess to get 1710 length you would need to do the maths and allow for blade thickness, and then set the rail up from the offcut end of the sheet as things stand? I'm guessing that might make the guide and track a little unwieldy? It's also a shame the t track aren't 50mm longer so a 2440mm sheet of ply could be cut exactly in half.

21:35 at this point would a rack and pinion be a better path? Eliminating the the need for lead screws? Use the track for drive and remove the sag? I’m eager for the beam side but I really want to eliminate the lead screw

Would you share the lead screw support file I think it would work for another cnc I am building

Is this project alive? Have you any thoughts about its issues? In my opinion, a square tube will provide minimum accuracy and repeatability of 1-2 mm, especially diagonally. But maybe I'm wrong ;)

Hi Jamie, where did you get your leadscrews from?

Building a CNC that big to. We have 1500mm X lead skrew. How bad is the whip on Y ? Curious. For that reason we went with toothed belt . Our x has really big whip, under fast acceleration😧 Could properly be fixed whit pretension 👍 What kind of spindle do you plan on using ? We went with a water cooled one. Was thinking of getting a cw3000 water cooler any opinion on that ? Great job so far. Greetings from Denmark 🇩🇰

Excellent build and excellent explanations of the dynamics in play with large format machines like these!

Hello Jamie, Sorry mate but I gave you a thumbs down, good project but you need to fix your sound levels, you speak softly but the music is to loud, I had to adjust the volume with every scene change ( or her indoors would crack it ) in the end I gave up. I'll check some of your other videos as it looks like you are a knowledgeable guy, I hope you are able to get the videos as good as your projects.

Greta video, where are the next parts to it?

Any chance you could share the side support files please?

Would it help to fill the steel tubes with concrete or something like that? Should increase stability but also weight, and maybe the sheer forces in the center are too big - I don't know. Have you considered it?

we really need pt3

sorry it is pt1 available?

Okay idk
