3D Printed CNC Machine V3

[@Grairo84]

hello friend very good tutorial, can you tell me what 3D program you use to design the plans?

[@LeonvandenBeukel]

I've used Fusion 360 for this design but for my next project I will probably use FreeCAD which I'm currently learning. The reason I'm switching from Fusion 360 to FreeCAD is the recent license change from AutoDesk. My guess is that Fusion 360 will not stay free software in the future. So if you're new to CAD and 3D design I recommend learning FreeCAD. Another reason to switch is that it's not easy to share designs as open source on for example GitHub. You always have to export to STEP files and later import.

@@LeonvandenBeukel You can 'export...' your Fusion 360 design in a '*.f3d' file (Autodesk Fusion 360 Archive Files) in order to share it with others.

[@PiefacePete46]

​@@LeonvandenBeukel : Someone with a more informed source than I have might like to confirm the following; it is not from any official source, and I am not part of the "In crowd"... * There is an expense to Autocad where translators are provided to allow files from other systems to be opened or imported in Fusion 360. ( ie: NX, Catia, SOLIDWORKS, Inventor, PTC Creo, etc.). There is also an expense to them when they provide "one-on-one" support. * The translators (as far as I know) were not available in the Hobby/Startup licence that is to be replaced by the two new licences. ("Startup" and "Personal") Also, there was no support at a personal level. * If Autodesk are to "woo" users of other systems, they need to provide them with a way to continue using their existing files, and provide them with meaningful support. * The new "Startup" licence will (I think) offer this. * The new "Personal" licence will continue to lack translators, and will rely on forums and tutorials for support. For me personally, this is fair enough. Being given free access to software of this calibre is a real gift for a retired person who is not in a position to give anything in return, other than my heartfelt thanks. There is, of course, a benefit to Autocad from the "Personal" licence... Dad likes to "dabble" with CAD... Dad shows kids what he's done... the kids become fluent in Fusion 360, aided by a 3D printer... the kids look for jobs, and they can boast their competence in Fusion 360 in their application... they get the job, the new employer has reduced training costs... WIN, WIN! I love what you are doing, thank you so much for taking the time to share it. *** Invitation to all you serial "Dislikers"; Have a ball! Blow this to smithereens! *** :o)

@@LeonvandenBeukel That is an awesome build. I'm planning on building a CNC like this for a while now. Could you perhaps provide the Fusion 360 design of the whole machine? Perhaps I'm too stupid, but I could not find it in the Github files.

[@senilegamers6197]

Hi just want to say thanks for taking the time to share this. I have built this over the last few months during the lockdowns and its working great. I increased the size of the cut area to 80cmx70cm and its still good enough for the projects I've been using it for. I have been using a cheap Lidl trim router for now but will change to the Makita one for a little more power In the next few weeks. But just wanted to say I really appreciate that you took the time to build this and share with us.

[@NoTimeForThatNow]

Thank you for this! I made my cnc based on your v2 files and I adapted the dimensions to materials and hardware found in the US. Great design, truly had a lot of fun making it and using it!

[@janvier7581]

Can you give me the link of your work

[@NoTimeForThatNow]

I haven’t posted it anywhere, but I guess I could put it on thingiverse if Leon does not object. But it is also the previous version, not this one.

[@bobbyboy1962]

@@NoTimeForThatNow interested myself as i also made mine with a more available 3/4 and had to redesign some 3d printed parts to make up for the difference in size. How did you do it

[@NoTimeForThatNow]

BobbyBoy1962 it took a while, over a week, I had a few misses and had to retry. But I basically tried to use all tubular steel, which worked great. I adjusted the sizes of the holes the tubes went into so that the center would still be the center wherever possible. The motor mounts I was able to use bridging to make them very effective and they work both as mounts and as bed stands. The biggest pain was marking and drilling the plywood for the sides of the xz axes and trying to cut everything out of the limited plywood I had. If Leon leaves a comment here that he’s ok with me posting on thingiverse I will and I’ll drop a link here.

[@LeonvandenBeukel]

Sure, no problem if you share you're modifications. Great to know you've managed to adjust it to your needs. Besides putting it on thingiverse you could also create a pull request on my github page if you want me to put it there too.

[@clivetoogood1447]

Brilliant design, so I built A V3 with a few changes to suit my workshop. Printed all on Tronxy 802 (anet clone). I don't know why but had to rotate a lot of the stl files to make printing normal. Had a few mishaps along the way like over tightening bolts and breaking parts etc. Now putting limit switches on but your info is a bit sketchy on this so a bit of reading still required. One question is on the stl parts list there is a Z axis spacer that a cant find a home for. Found a nice way of adjusting y axis runners I tightened top 3 bolts but left the bottom enlarged hole bolts slack and then inserted threaded bars that holds top and bottom runners together (also slack) then put on a spare piece of 20/20 rail and used wood clamps until smooth and tight then tightened bottom 3 bolts up and tightened the threaded rods gently. Removed spare rail and put onto actual y rails. Mine went on beautifully with no more over tightened threaded bars to break or twist components. Thanks again ******Leon*****

Hi Leon For the X and Y linear axes (20x20mm square tube), you should fill it with Acrylic Resin and 3mm metal bars on each side of the tube to avoid bending by the movement and force of the cutter. Thus obtaining better accuracy. Wilson ...

[@IAintScaredOfNoGhost]

For the same cost as resin he could upgrade to polished ground rods. This project is an exercise in frugality.

[@jeucedahn]

Really nice job! You are improving your machine a lot with each version, thanks for sharing!

[@Dancer148]

Nice design but I see a tolerance problem. On the lower two tubes: Using bearings twice on both sides of the square tubes eliminates play except for slight tube bending in the middle. On the upper two tubes: Using bearings only on the top of the upper tube and on the bottom of the lower tube will have all sorts of play by only upper tube bending in the middle while the lower tube stays straight. When the (mill) tool will press on the worktable then the inverse will occur where the Lower tube will be pressed upwards and the upper tube will stay straight. Solutions: 1) Bearings twice on both sides 2) Use springs to press both bearing gliders to each other

[@LeonvandenBeukel]

Thanks for the suggestions

[@Dancer148]

Now that I think about it... Not only will the solutions solve the play tolerance problems but gain also twice the.tube strength because of now full support.

[@tjkoker]

Very clean and frugal design. My only concern is the metal bearings against the metal guides. This can wear and cause inconsistent cuts. Might want to consider hard rubber roller bearings like the material used in skateboard wheels. Other than that great work.

[@marcerasmus3745]

Brilliant work Leon, very inspiring!

[@petittoto7433]

Nice ! A little engineer trick if you do some modifications for the X axis : it would be better to have 4 bearings on the bottom rail and the top one rotated 45° (flat) with 2 bearings. So the guidance is stiff (short distance between the bearings on one rail) and you avoid any problem of distance between the tubes (and if one is not really straight). The same could be done on the Z but as it is smaller it is less important.

[@salvatorebarbaro5862]

Why not put the gantry supports upside down? , with motors and bearing housings facing outwards! in order to keep them clean during processing, and also to increase the spindle stroke.

[@Juliano.c.g]

Hello Leon. Why did you invert the position of the step motors to inside from V2 to V3? Now it seems they are exposed to dust. Can I flip them out without having to modify the parts? Thank you for share this project, I'm thinking to make it here.

[@guywhoknows]

Nice neat design. I was thinking that it can be a fold/slide away unit to fit in my workshop, but I couldn't have a enclosure or fixed base. Only concern is the wear due to the seams in the box steels. This is only one side, so nothing major. Hope you left the plan and 3d prints in the discription. Or you have a site to sell the parts...

[@Catalysis1144]

Nice design thanks for sharing. I had always thought of building a similar machine but my idea was to use dual V wheels riding on the top and bottom 90deg corners of the square tubing when mounted at 45deg the same way you have mounted them.

[@chuchy96]

excellent work . I have two questions for you: 1st how is the machine stronger, with straps or spindles? Do you think it would be improved by mounting solid square profile (instead of square tube) or do you think that it is not necessary? 2nd with the straps the machine is faster retains accuracy. Thank you very much for sharing your talent and congratulations.

[@islanzadi1]

That looks way better than mpcnc. thats crazy good. keep going, great video.

[@b5a5m5]

The issue you have with your belt is because of the way you designed the belt path. You need the belt to go straight from one side to the other, with the idlers not deflecting it from that line. This way the length of the belt stays constant no matter where you position the y gantry.

[@barry4600]

Leon, won't you lose a bit of accuracy using belts as there will be a certain amount of stretch as your moving in the X and Y axis. I made a little mini desktop one and found that as soon as the bit started biting into the wood the belt would stretch a mm or two and then spring back tight as soon as the bit was lifted off the wood, maybe I am using to hard a type of wood?

[@karipenttila2655]

Why you did not do the new wooden parts with the router before disassembling it? But the design is nice! Would it be better to have y motor plates so that motors are outside?

[@restholzjunkie]

@leon: Currently I'm printing the parts and have some remarks to the left side of Y-Axis. The Y-Mounts need to turned with the long holes to the inner side. The Motor also should be mounted upside down like the right Motor because the way it's shown in your Video you cannot mount the GT2 Belts square to the Holders and Wheel at the Motor. The Direction of the Motor can be changed by turning the Plug at the Channel of the Y-Axis on the Arduino shield.

[@denisbeautrix1829]

I bought 4 square tubes for x and y. For cleaning and a bit polishing I put them each against the others and I can see that one of them was bent of +- 2 mm on 1 meter. That could have created a problem hard to find for the accuracy. Check it out! 🤨

Congratulations for the project & build, looks very sturdy and functional! Which wall thickness did you use for the 20x20 steel tubes? And do you recommend stainless steel or regular? And how much Z-axis travel do you have with this design? I'm thinking of building my first CNC, but I need at least 60mm Z-axis travel.

[@PeterHertel]

I have all the parts printed and are in the process of assembly, but have not completed the z axis yet. I do think you can get 60mm z travel if you mount the router lower, but that could affect cut quality. I say if it's your first cnc go ahead and build it then modify it later to suit your final needs.

[@sarahclark5447]

As part of a school project for the coming year, our team is set with the challenge of making a CNC PCB isolation router. the accuracy and repeatability has to be phenomenal. Obviously highly accurate ball screws and precision linear rails goes a long way to achieving that (apparently). The milling area is only 160mm by 100mm about 6-1/2" by 4" is that the way to write imperial measurements? so the machine will likely be very small. As the only girl on the project, I am their slave, seriously lol. it will be me having to beg and plead with companies to give us expensive ball screws and the like. Believe it or believe it not the first item I have to acquire is a 3D printer so we can make the plastic parts that presumably do not affect the overall accuracy of the finished machine. You are wondering where this is going... well, I haven't a clue what a ball screw does or even what one looks like, neither do I know what is a suitable 3D printer, but of course you guys do. Could you please tell me what make and model 3D printer I should be looking to "acquire". keep in mind I have to talk a company out of one of these machines so it needs to be arguably what we need, not let's have the Rolls Royce. I am not after freebies from you guys just your advice and experience. Oh, does the 3D printers come (in the box) with everything to say make a gizmo? only I noticed in this video the guy pulled a part-out of the 3D printer as if it had grown there! How did the 3D printer know how to make that particular part. Did it use expensive software that if you didn't have, the 3D printer would be as useful as a PC without windows on? Thank you in anticipation of any advice you can give me. Miss Sarah Clark, 15 from the UK.

[@IAintScaredOfNoGhost]

Any 3d printer will come with software, if bought from a company. Only handbuilt 3d printers do not come with software (somebody just buys the parts and puts the machine together themselves) Your best bet is to Google a "makerspace" near you and ask your questions in person. You'll learn a lot faster than asking in KZbin comments.

I am thinking to build this version of your machine but to maybe put it on the outside in order to save some machining space. Also the tubes for the X axis would be a bit shorter and maybe more rigid. Do you think that would work, or is that a bad idea for momentum / power transmission reasons? Thank you!!

I was looking at that too, I'm thinking that you would lose a certain amount of Y travel by putting the X motors on the outside. If you consider the cutting bit position in relation to the edge of the Z carriage I don't think you would gain a lot by reversing their position, maybe even lose some width..?

Hi Leon, Which software do you use for your CNC router. Thank you

[@LeonvandenBeukel]

Fusion 360

@@LeonvandenBeukel I just checked and looks like you can do 3D models with it. Could you make a video how you do a model and then convert to GCode for CNC. Thank you

Good job Kiddo!

Nice build. Just FYI 4:30 that is a masonry bit for brick

I know, it prevents the PLA to melt
