it needs another piece of 2040 in the middle under the bed to tie it all together and to stop any push down above, on my version of this I have a piece of 8mm tapped aluminium for this bed and that is screwed down into the extrusion in on all 4 sides, its as rigid as it can gets now, finally it needs a brace across the two X axis 2040 extrusions , doing that makes X and Z very rigid. I used a piece of stainless steel that I had for this at 3mm thick. It makes a big difference now. Once final thing is I have the entire machine bolted down on a large desk which is heavy and has a thick counter on it made of a piece of granite. I then built a full enclosure which goes over it and keeps the noise down by about 30% and because I use a 1.5 kw VFD water spindle it is loud but very fast and accurate , mine also has ball screws rather than lead screws. its worth the extra cost which is not that much to be honest and helps to reduce backlash by quite a bit. My extrusion is bolted together rather than using corners which are fairly useless, simply drill through, counter bore and tap the end of the other piece with M5 allen heads. If you look closely in the video this was put together for speed of the video and most bolts and screws are missing. There are also some steps missing, you do not need to use the controller tin this video, any small grbl controller will work but you might need driver amplifiers.
@@nerviantone in the end, I abandoned building this because I decided it was too small and I ended up getting a machine from rat rig which is far stronger as a much larger bed of round one square square metre and takes some much more powerful spindle, this machine by the time you have the plates cut out and buy everything is around about €650 for 1200 I was able to get the rat rig machine and just put it together myself. I'm not saying this CNC is not good. It was just too small for me once I looked at the cost in full. I made the decision to change. basically this is an upgraded 3018 or similar like a fox alien and it's a nice little machine. It really is too small for anything decent as I said in my comment I think there are some pieces missing that need to brace it better because once you start cutting metal out, which was the prime reason I wanted to it use it for on brass copper and aluminium I felt it would not have the sufficient power or strength to give me a good finish. Good luck.
Nice video...Sir please make a video on higher/improved performance CNC machine something like laser cutting.. I mean all the mechanical parts should be easily available in market and there shouldn't be no 3D parts ( not everyone can make 3d parts, so implementations by viewers will be tough without all parts).
Really nice design well done - may I make a suggestion for even better rigidity? The rigidity in the X travel could be greatly improved by putting a web between the upper and lower black extrusions atm the gantry can flex creating a parallelogram shape
basically stick a piece of metal on the back of the two X extrusion bars that way it will be more rigid, either a whole sheet the width of the CNC and between the centres of the two extrusion bars. so about 500 mm wide by the height....dead easy, its already quite stiff but that will make it very stiff @@sanjaybatra6593
Congratulations, it is a spectacular project. Could it cut metal pieces? At least light metal like aluminum? What other types of materials could it cut?. Regards.
I suspose at some point you went back and aligned/squared everything? Not sure how or maybe I just missed it but you have no alignment or dowels to even remotley have accuracy. But If thats not what your going for. I guess it works.
Huh ? Do we really need that big control box ? , itsnt it just enough to have a microcontroller and supply for it cnc shield and motor drivers for motors ?
google, tons of programs out there, most free. The question you should be asking is how , calculating them is easy ,machining them is another deal all together especially if they are in metals but this machine should be able to do that reasonably easy asper thevideo, just takes longer with metals.
limit SW come all axis own to GND and input pin thats all. 2 limitSW x axis etc, add SW paraller and then to board gnd and input pin. thats all. simple- same E-stop. home SW probe,etc etc.
hello sir i want a stepper motor driver ic that is smd and 30 pin but i don't know about its part number please if you suggest me i am very thankful to for act of kindness.
I would think that this style of linear rails rather than the round rod style would be more likely to be affected by the dirt and dust created by the cnc requiring more frequent maintenance. Great project though.
round rods sucks, they sag and affect the stiffness of the machine. linear rods are much better and they are somewhat hidden because they are on the sides
@@MrInnovative Yes, but you can use a simple adapter for any driver. The adapter is installed instead of the driver on the cnc-shield and allows you to connect any driver. It's very cheap. In any case, your project is amazing! I'd love to see it!
@@ХерлуфБидструп-м1я not need adapters, all external drivers need only arduino or cnc shield out step , dir, and enable pin, not more need, to drivers, and big power 36V maybe most used, to drivers and big nema 23 or 34 motors.
We have very cheap and high-quality linear guides, ball screws, linear modules, linear optical shafts, linear bearings, needle roller bearings, and rod end joint bearings. Do you need them, made in China😀
I built this the board and a cnc but for some reason the UGS doesn't recognize the board and says I need to configure it manually? Did you have this issue?
NO if build it ready to run kit cost optifinity etc, many other cnc 4000-8000$ and i has build little better and biggest cnc better parts less than 1000$ what onefinity has.
Great job, very professional wire routing with the din rail connector points. I had extected to see some din rail breakers for the stepper drivers but maybe they've got them built in.
750 to 1000 usd for something like this with a good mill and controller, you need a palm router or a VFD water cooled spindle , I costed it to around 600 euro plus the controller and VFD takes it to a grand. if you use a router then take 300 off but it will be very noisy....this I am sure can cut steel , it needs stiffening in places and mounting on a solid desk and it works very well....
@@spiritburners palm router have worst option cnc machine, i has before but same cost real good 800W aircooled ER16 spindle lot lot silent and better collects and better torque than router have. cost about 100$ aliexpres.
ballscrews ghave lot lot lot expensive than lead screws. T8 lead screws cost 4-7$/axis and ball screws same size cost 80-140$ axis. no need waste money stupid.
Hi, I wana buid or can say upgrade my sewing machine using grbl motion control system and plan to do embroidery using inkstich post processor. Is it possible to do this. Can you give inputs on this project.
perfect beginner cnc build have arduino+grbl+nema23 470 oz/3Nm+ DM 556 drivers. and 800W air cooler ER16 spindle. if want cheap and easy and good first cnc build. better use MGN 15 or SBR 16 linear rails. very cheap set.
hoi , i like your video. i want to make one for my own. but i have a question. can i use a laser too.? and if that is possibly how can i install it? greetings from Holland.
i dont know if his controller supports a laser but a new controller that does isonly about 50 euros,. its a easy swap and replace to do that and then this machine can run a drop in laser as well as the spindle, if however you are just interested in lasers then buy a ready made laser kit as it will be very cheap compared to building this. Its a semi pro CNC that I expect will be able cut steel which is the holy grail of CNC cutting machines, aluminium, brass and copper and finally all woods will be effortless with this machine. Its super over engineered.
not need, can buy ready to use board less than 10$ 3-4 axis. arduino cnc shield or many many other options have use arduino + pc or raspberry pi or mesa card or protoneer cnc board or klipper, or fluidcnc or many have less than 20-30$
need big stepper drivers, what have motors max current need drivers handle same current, and all other have same ewery motors. nema 34 use normal DM 860 drivers good. and setting max current little less motors maximum.
its a 500 watt ER11 spindle i expect I wouldnt use this just stick in a Makita R700 or Clone router and change the clamp that holds it. The 500 watt motor is rubbish on this ,you need much more power and the makta will give this, failing that a water cooled 1.5 kw VFD spindle
@@sitgesvillaapartmentneilsc7924 worst spindle use makita or other router to cnc noisy and weak power, 800W aircooler ER16 spindle have lt lot better torgue and silent than any worst router.
yes, i has one cnc 2500x1500x200, cutting plywood full sheet. biggest cost linear rails more only, all other parts cost same. but normal big machine used linuxcnc software mesa card and ema 34 motors and drivers. big need lot biggest motors too can move all.
THANK YOU FOR A GREAT VIDEO and some good ideas. I got a 3018 6 moths ago and I would recommended anyone to get one to start with as it is a cheap way to get into CNC routing. I found that I really like it but I now would like a bigger machine (only with a work area of 500mm X 500mm) so I am designing my own. As the ones you can buy cost too much. Like the idea of using threaded bar all the way thought the aluminium extrusion. Like the idea of two motors for the "Y" axis. I was thinking of using 20mm rail NOT 15? I will have to look at the different now? going to use HSK only because there is a supplier about 8 km from me. using a belt on the Z Axis is a great idea as it save on the Hight of the machine. why did you use Mild Steel and not Aluminium? steel is stronger but Aluminium is light and I thought it would be OK for something this size? Thought you might of used Ball Screws instead of Acme Threaded Rod?
steel frame makes it super rigid unlike a 3018 which is really only good for light wood and soft plastic, it causes chatter because it has steel rods instead of linear rails. this cnc will almost certainly be able to mill steel. it is that strong, aluminium brass and copper will be a breeze, if you are thinking of building one use this and change lead screws to ball screws and buy a different controller and it will work very well. I build small cnc's for a living and this is one of the best I have found to base my designs on. Its not the cheapest but for around 700 euros you can buy all the kit and have a 3000 plus machine that will cut almost anything I would imagine.
Efektownie ale z mechanicznymi błędami . Brak kasowania luzów na śrubach pociągowych , brak łożysk oporowych na śrubach pociągowych , zbyt cienkie prowadnice , brak stabilnej podstawy to błędy . Nawet przy najstabilniejszej konstrukcji brak wymienionych elementów czyni całą obrabiarkę tandetną . Reszta to składanie kloców lego . Zdecydowana większość filmików o obrabiarkach CNC zawierają te same błędy konstrukcyjne nie naśladujcie bo szkoda czasu . Niewielkim kosztem można te błędy wyeliminować zastanawiając się w którym miejscu powstają ugięcia i luzy mechaniczne , właściwie 100% takich pomysłów to lipa - widać robią to ludzie nie mający pojęcia o mechanice albo robią to celowo by ludzi zniechęcić do budowy swojej konstrukcji windując koszty ,kreując firmy produkujące badziewie za grubą kasę . O głowicach wspominać nie trzeba zamiast kupić porządną frezarkę z regulacją prędkości na dobrych łożyskach sprzedaje się reklamowaną tandetę - frezarka dobra do takich celów kosztuje 3/ 4 stówki
How well will this cut aluminium and brass ?? I'm interested in making this as the old Mach 3 3018 I have is not really up to it, it does do it but very slowly and it suffers from chatter and backlash, this has much stronger supports, linear rails etc so I would expect it to fair a lot better I need to mill brass and copper in small runs. thanks
need only usb or paraller controller board, better nema 23 or 34 motors, biggest DM 556 drivers and good spindle 800W air cooled ER16 spindle or 1,5KW water cooled spindle whit VFD. minimum nema 23 3Nm motors. lot biggest need steel. about nema 34 9NM motors.
Well done? Excellent job? 1. How much it will cost from learning point of view? 2. Do all the mechanical part are available or some part will have be manufactured on order ? 3. Any offline training?
