The Cheapest CNC Milling Machine

Ғылым және технология

PCB Milling was on my TODO list. So I thought I'll give the cheapest CNC mill a try that isn't made from card board. You would be surprised how far I got within two days of messing around with that. The fun alone was worth every penny of this purchase. Enjoy!

    FlatCAM to generate gcode from gerber and bCNC to run the machine work for me. Also, flip the spindle mount over. It will stabilize the depth of cut. The machine actually supports probing if you hook the copper of the board up to the A5 pin on the header and ground the spindle (be sure to isolate the copper from the machine). This will allow you to probe and compensate for errors in the height of the copper on the PCB and control the isolation width. I've made a bunch of very high quality boards with this machine - not as good as having them manufactured, but a lot faster.

    @Doug Cote Indeed that is the way we used to do it before PC's and CAD/CAM software became available. I still write G-code for simple bolt patterns, circles, etc. I worked for a bus manufacturer in the mid 70's and they had a huge CNC punch press just outside my office. There was a guy in Engineering whose only job was to translate sheet metal part drawings into G-code for the punch. He had a CDC PDP-8M Minicomputer to help with nesting parts, but the majority of the code was written by hand. I can still hear that punch cutting curves in 4 ft. X 8 ft. sheets of steel by "nibbling" using a 3" round punch. Made a HELL of a racket!

    As others have mentioned, FlatCAM and bCNC are pretty good. For flatcam, the beta version from git is radically enhanced and is fairly stable. Use auto levelling. Always. Never fix PCBs with clamps, as it warps the board and makes it flex under pressure from the mill. You are working on 35 micron copper. So you need precision. I use scotch blue tape (the really flat version) on both the support (some MDF), and on the back of the board. Glue them together with superglue, and you have a very stable and rather flat surface. Auto level will do the rest for the flaws in the flatness. There is no cure for a lack of stability, so you have to have taken care of that. I manage to do TSSOP (0.2mm traces) this way. Test your mills before using them for real. Many chinese mills are off or leave burr that will be a mess to clean up properly later on. Go slow, high RPM. 8k RPM is a minimum. If you do not have high (16k+) RPM, in aluminium 6060 (a regular, rather soft version, but that trends to stick to the tools), go very slow, use 1 or max 2 flutes, and take very shallow plunges: 0.2mm depth at a time. Don't try harder Al (like 2017) or steel if you do not have the RPM nor the stiffness. Roughly speaking, the spindle RPM will mainly determine the speed you can go, the stiffness of the CNC will determine the precision you can obtain. This is a subject in which you can put a lot of time. You will find out the strengths and weaknesses of the different tools that are available, and you will spend a lot of time and money on it (even when you buy from China) Would it be profitable to use professionally? Not unless you need really fast turnaround times. Lately I have seen more and more non-chinese PCB shops that can be pretty cheap and fast. Will it give a lot of fun and will let you mill custom panels and housings? Yes.

    I worked on CNC machine for couple of years, so here is some advice to make your experience better: - Use ArtCAM to generate g-code. It not only has a versatile array of options and code encodings, but also takes in consideration material warping due to pressure from the mill, so it will generate path to counter the warp. I don't know about any other software that does it. ArtCAM can have a tool base, takes into consideration angle of a tool tip when generating a path, so it will not damage any unwanted parts, if the tool can't reach in there, so your connectors wouldn't be eaten away by the too wide of a tool. Additionally it can work with reliefs too. Back in the day I modeled and milled pendants, buttons, badges, plaques, etc from brass, copper, plexiglass, graphite (real soft, but very dusty) and aluminum sometimes. - Use Mach3 to run the code. It is very cheap and versatile, supports a lot of machines, and it is highly configurable. If you use ArtCAM in the combination with Mach3 you want g-code type "G-Code Arcs (mm) (.tap)" - When choosing materials you need to take into consideration if they are more brittle or elastic. Brittle materials you can easily mill, like brass ZAMAK 3 and ZAMAK 5 type. Widia tool is the best since it is very hard and can take a lot of pressure. I even managed to mill steel, although you will need a way stronger motor for that, then the one that came with the machine, and at least 4500 RPM and very slow feed rate. - Copper and aluminum on the other hand you don't want Widia or it will break as soon as it touches the material and you will have jagged edges. This is because elastic materials are bending around the tool and heat it up, then pull it back. Widia can take a lot of pressure, but only vertically, even a smallest amount of pressure on the sides and it will break. If you drop it, it will break. For those kind of materials you actually want stiria tools. They are waaay better. They are a bit softer than Widia tools, but for elastic materials, they are perfect. - Other than brass, you also want fluid to help with milling, to keep your tool cool and to assist during movement. For copper you want machine oil, which works for steel too, for aluminum I found that 70% alcohol works best, and plexiglass is milled perfectly with water. Otherwise plexiglass will mill with mate surface and most often you want clear surface where mill is passing thought the material. Listen to my advice, or not, its up to you, just wanted to share a bit of experience and most importantly have fun in your craft :)

    This was adorable to watch, being a machinist my self, and brings me back to the days when I was a teen - Making PCB by hand and going to Radio-Shack. Lots of rookie mistakes (not that you were looking to be a "machinist" by any means). So much fun to do this stuff when you have a mill that works for you! Definitely need the right tools for the right jobs though. You'll want something along the linnes of a 2 flute 1/16 straight endmill, maybe even carbide, but if you use HSS (high speed steel) it would be easier to do what you are looking for without adjusting for the taper of that engraving tool. You could do a 1/8th for a majority of the dead space between traces, then when you want closer, you use a smaller tool to get closer to the tolerances you are looking for. Changing tools is key to these kind of works. You can get very very intricate with a 1/32nd tip, but you have to go fast and light around the traces and do multiple outlines on the contour passes. Neat buy for something that cheap! I was surprised actually that it could mill out even that amount of material like that. Build out a small blower fan and a nozzle to help blow out the "swarf" so your cutter doesn't dull out or break, keeps it cool too for the cut.

    Some quick recommendations: 1. Bolt it to something heavy. Like a metal plate or block of wood. The added mass will help with any vibration (and keeping the mill from dancing across the table). 2. Check the bed's height with a feeler gauge. This will make setting the tool height easier, and you'll be able to measure for any tilt in its mounting. 3. Add a wasteboard that you can then mill flat relative to the machine head. Even with software correction it will still help with accuracy.

    Just as a hint from a machinist/mechanic: Tools usually come with a rated cutting velocity or Vc. Using that and using the diameter of your tool you can calculate the recommended spindle rpm using this formula: (Vc [m/min]*1000)/(PI*diameter). In the case with your tools I would just set the spindle speed to max really since assuming the tool tip from that 60° cutter has a dia of 0.5mm and a rated Vc 0f 50 you'd be looking at 31000 rpm

    Wow, this brings back memories when I first tried to mill boards of my own. It's really difficult to overestimate just how difficult this is, to get usable results with medium thin traces and pads. You find out really quickly that no board is completely flat, which can spell the difference between no trace and breaking a bit when you're using extremely thin v-bits. You really need to probe the board with a small mesh size to capture all the potential dips and bumps. Use silicone oil or another light oil to prevent chips from sticking to your bit as well as extending the bit's life, and run the spindle speed as high as it will go with carbide bits.

    A really easy way to improve your clamping is to add a piece of material on the other side of the bolt. The idea being to support both sides of the washer so that it stays closer to flat; probably easiest just to use a few scrap pieces of whatever you are cutting. Alternatively drill a couple of holes through the plate and clamp through those holes.

    just a tip: dont let your wires create loops. Although this is a very small piece of circuit and the wires aren't that big, it is a long going habit of mine. Once, in my electrical classes, our teacher explained why you should never let your wire create loops, and he demonstrated it. It basically becomes an inductor, and it can lead to some metal melting, and eventually a huge fire. Take care, great project!!

    Good job! I mill prototype PCBs with that CNC type too, only a larger version. I am able to achieve somewhat finer resolution by using a probed Z height map, but this step will slow down the process somewhat so it depends on what is necessary. Prototypes are meant to be quick, so only do what is actually required. I think your results are very good, knowing you just got this machine. I also built an acrylic/wood enclosure with dust extraction, an enclosure to protect the motherboard, active cooling of the stepper motors, emergency off switch, push-pull style blowing and sucking away the milled chips close to the router bit using Loc-Line flexible hose, drag-chain on top for the router and Z-stepper cables, additional ball bearing for securing the lower section of the Z lead screw, end stops, plastic end caps for the 2020 profiles, and other miscellaneous things, but none of that is really required or perhaps worth the effort. I also used a pro CNC router some years ago to mill boards, and of course it is possible to achieve better results with pro machinery that are more precise and heavy-duty, and also closer to 20000 or 30000 RPM instead of ~8000-9000RPM, but they cost ~100 times more. If I need quality boards, I finalize a more compact PCB design and order from JLCPCB like everyone else. I now use FlatCam and Candle. Sometimes I use cheap Chinese V-bits (0.1 or 0.2mm), and sometimes I use (also) cheap, second-hand refurbished 0.4mm end-mills from professional CNC shops that sell lightly used bits on eBay. I usually use very thin double-sided tape to stick the PCB to the backer board instead of hold-down nuts.

It's just another tool people can use, and it offers a lot of maker flexibility with milling, drilling and cutting PCB and also other material. It is correct to point out the difficulty level is quite high, and the difficulty is further increased by going for a low-end machine like this. A professional machine will make many aspects of PCB milling easier and more productive, but that's also why they are so expensive. I do some etching too, but am not really a fan of chemicals. That's my my personal preference, for other people they have to choose what they like depending on their project types, work space, ventilation, noise considerations, project deadlines, tools they already own, availability and pricing of ingredients, materials and accessories, primary areas of interest, preexisting skills, budget, and many other factors.

As a lot of other commenters have said you need to get your Z height spot on. Also looks like your blank stock was warped in that first test which will cause you no end of problems. As for the chatter on the sindle.. That what more expensive machines are for or look for slop in all the linear bearings, backlash in the drive system and make sure everything's tight. Then mount the whole unit to something really substantial it will help with the chatter.

    Nice CNC! You deserve many likes to contribute to the replacement of broken tools. That said: I think that for the use of conical tools you should take more into account that the plates are not completely flat, so you could use only very thin cylindrical tools and mill the material in successive passes of only 0.2 or 0.3 millimeters in order to preserve your expensive bits. Or you can previously map the surface of the plate and add the shape to your z coordinates so that the tool always penetrates the same depth into the plate

    Hey now! This may be useful to you. I recommend using a larger sacrificial board, and mounting your workpiece to this with 3m thin double sided tape. Then you wont have the piece running off on you when you finish cutting it, and it will be easier to lock down the larger sacrificial board to the machine

    I would also recommend FlatCAM. I have made a couple of tests with small boards (I find it eaiser to iterate -- and less waste) and for now I'm using 0.5mm for the traces. Also, in FlatCAM, use multiple passes (something like 5) with some overlap (30 - 40%) for the top/bottom layers. Use the calculator tool to calculate the tool diameter when using those V-bits. And DON'T MILL WITHOUT AN HEIGHTMAP!

    When cutting metals it is extremely important to properly set your spindle speed. This controls the velocity of the cutting edge through the metal. Small air cooled spindles operate at RPM's so high that you are limited to very small diameter tools. For instance, if your spindle is running at 24000 RPM you will not want to use a tool larger than about .010" (.254mm) in aluminum. Using too large of a tool will increase cut speed so high that it will quickly dull and start pushing around material instead of cutting it. When using very small tools make sure they are of very high quality; miniature tools are difficult to properly manufacture. The last time I used a micro end mill I believe I paid $50 USD, (it was a .050" long reach reduced shank square mill i think), and snapped it in half 3/4 of the way though the job. Small tools are tricky to work with. I would also recommend using liberal amounts of lubricant, tap magic is great for aluminum, but in the end this machine is simply too small to effectively use larger tools and will always struggle cutting metal no matter what modifications you make or tooling you select. If you really want to cut metal pick up a mini mill with an R8 collet; that is about the bare minimum to make anything useful.

    YOu have to be careful with longer extrusions: that means more flex and less accuracy. You have to increase the cross section per increase in length. You should also go rectangle instead of square. I built mine with 80/20 2" x 6" 3 web I beam. I used their calculator to determine I would get .001" of deflection in the middle with 300 lbs of pressure.

    I bought myself one of these 2 years ago as I always really wanted one, finally I had enough spare $$ and convinced myself I would use it for making pcbs.. I hit a speedbump right out the gate, the rail mounts were for a 8mm rod, and the rods and bearings supplied were 10mm. luckily a local machinist answered my post on my neighborhood facebook group and kindly drilled them out for me (on his bridgeport mill :| ). quickly found it to be useless for milling PCBs, and so I have stuck to the tried and tested toner transfer & etch method.. I do still use the machine though for drilling the pcb holes, but I replaced the spindle with a 400w 12000rpm Chinese spindle (that makes a hell of a racket, but that I think is also partly how the spindle is mounted to the z axis) I have also added a beefier PSU and a digital rpm display. I find the best way to hold the PCB is by using very thin double sided tape, sometimes called carpet tape, to fix it to a sacrificial piece of high impact polystyrene that in turn is held to the bed with the supplied machine screws and t nuts. Like many others in this comments section, I use bCNC and Flatcam

    It’s built of a cheaper Chinese version of 80/20’s extrusions, as so many Chinese products are in the 3D printer and small engraver/mill market. Substitute a small laser model from eBay, and you’ve got a laser engraver. Those “ pointy” bits are engraver bits, not milling bits. Be careful how you use them. And NEVER use an engraving bit, even the heavier ones, for milling. The bits with the cross hatched cutting edges are also not milling bits. By the way, you need carbide bits for anything with fiberglass, as steel bits will wear out very quickly. I don’t know what your bits are made from. You need a proper plunge bit for metal. Those bits you’re using are “die” bits. Not designed for what you’re doing. Buy carbide bits with two flutes for aluminum. Make sure they are made for plunge cutting. Take slow cuts, and think about using some small amount of cutting fluid do the bits won’t become clogged with the aluminum you’re cutting. This is a problem with softer aluminum alloys such as 1001, 3003, etc. don’t use cardboard or something soft beneath. Elevate the part above the surface, and let it cut through so chips will fall out.
