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.

@@WillE86 thanks for your comment Will and you are 100% correct. My current machine now has a rotating ball nut and full steel frame with HGR 20 linear rails 👍 this initial machine was great for learning on cheaply and I made quite a lot of money using it which justified the upgrade. I was able to reuse all the motors, ball screws, electronics and spindle so upgrading wasn’t very expensive, the hard part was finding a working design that I could 3d print the rotating ball screw components

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.

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..

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.

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.
@jamieclarke3212 жыл бұрын
yea you would need to go from the offcut side to go over half a sheet like you say. I cant remember exactly the size i made them if its enough to do half a sheet but for them to be 50mm longer you just need to use longer alumium extrusion t slot tracks and they were very cheap. Might have been an oversight on my part

@jamieclarke3213 жыл бұрын
Hi Kimberly, I don’t really have any whip on my x axis at 2500mm/min but my ball screws are 16mm diameter and 10mm pitch. 5mm pitch means the screw has to spin twice as fast to move a set distance, this could be what’s causing your screw to whip. What size screw do you have? I’m running a 2.2kw air cooled spindle on my machine as I didn’t want the hassle of dealing with the water for the machine, air cooled spindles can’t be run below about 6000rpm so that’s the advantage of water cooled
