    I love how he has a cnc on his desk that cuts aluminum well enough and still proceeds to make parts for the cnc with the printer while knowing rigidity is the issue.

    Recently I had to look for someone to cnc me some brass parts for one of my projects, and the only one company that actually replied to my email gave me an astronomical price for their service, and now I found your video about buying and upgrading a cheap cnc machine on a affordable budget. With 500 bucks spend on cnc, 80 bucks on materials and a few days of work I can produce same parts much cheaper and also will be left with an amazing machine for God knows how many years. Good Sir, you are my hero! Thank you!

    Impressive!
    For machining gear-like things, I've found the best process is to first cut out the inside holes, then add more workholding in the center, cut a circle around the outside, and then start working the curvy profile. First use downward motion with the end mill to cut away most of the material inbetween each tooth, and finally do the continuous profile cutout (one rough pass, one finish pass).
    The circle allows you to use a large and tough bit for full width slotting, and together with the downward motion, the small bit never has to take a heavy side load. You also get much better chip clearing compared to cutting a curvy full width slot. This procedure is particularly necessary when using very small bits in very hard materials (I came up with it when making titanium cycloidal discs with a 1/32" end mill), but it's a great speedup for aluminum too.

      @@ericinventor C++ :) CAM software is outside my budget. Python would probably be easier, but C++ is what I'm used to. I also use 3D models in Blender to help visualize things.
      For best results when nibbling with vertical motion, always keep the center of the bit over open space. Involute gear teeth need several bites to get all the way in to the base of the tooth.

      @@ericinventor Mine is all written from scratch, but now that you mention it I should clean it up and make it available for others to use :) As is, it would probably be confusing trying to understand how it's meant to be used At its lowest level it's just functions like G01_XY which takes an x,y position, applies backlash compensation, and prints a G01 command to the output file. But I also have a functions to do more complex operations with a single call, like drillHoleCircle(centerX, centerX, numHoles, circleRadius), or cutHole(centerX, centerY, radius) which will cut a helical path downward, with tool offset toward the center of the circle, and then do a finish pass with .001" or whatever finish chip thickness you have set.

    Thinking about upgrading my 3018 but wasnt 100% sure where to start, this is really helping out. Cause i started questioning basically everything about it, down to the torque of the steppers. Its very nice to see that the most important stuff for somewhat speedy results are the z axis and the spindle.
    Cause i realy stopped using it alltogether since i kinda hit a wall already with some hardwood, only managed to go at a feedrate of around 100mm/min woth a doc of 0.25mm took me forever to do anything

    You need swan neck clamps to clam the metal down or the clam has to be level with the piece you are clamping. The lesson i learned from this video is to buy industrial level parts so you could use your cnc to make more parts that you need to complete the rest of the cnc machine. Great video.

    For me , linear rails on X and Z solved the "chatter" problem. The rods are just not up to the task. The 10K RPM spindle motor is the next to go - probablyy with the 30K RPM router. Thanks very much for all your input.

    • @Festivejelly
      @Festivejelly ปีที่แล้ว +1

      You want slower speeds for cutting aluminium. So you want low RPM but high torque.

    • @MaintDocs
      @MaintDocs ปีที่แล้ว +2

      That's good feedback. I've got a 6040 router I've had for 10yrs. It cuts a lot of alu & brass, but it's still on chrome rods instead of proper linear rails. I've been wondering whether the flex & chatter or the steppers are the biggest limitation to my cutting ability.
      Note: upgrading to flood coolant with soluble oil made a huge difference to it's metal cutting ability. Nothing I tried spraying by hand even came close. With flood coolant, you can run a faster rpm, so you can take advantage of a high speed spindle rather than trying to cut low and slow.

  • @richkay228
    @richkay228 ปีที่แล้ว +36

    A tip for hole "plunge" toolpathing, a far better method is to "helix bore" rather than plunge. 2 flute mills tend to chatter when plunging in the z axis only. If the hole diameter will allow (you will need a smaller tool to interpolate helical within the hole). Try it, I think you will find it mills much smoother. Not sure if your router has the capability to interpolate X,Y and Z , but just a general FYI Good luck !

    • @DodgyBrothersEngineering
      @DodgyBrothersEngineering ปีที่แล้ว

      But it is also a lot slower than plunging too. You need no backlash for it to work properly. He is just using cheap threaded rod, so I don't know if it would produce a better result.

  • @MikelNaUsaCom

    So what I got out of your video is to buy the most expensive tool you can afford... do your research and make sure that $$ is spent for what you are going to do with that tool. Use a hammer for nails, a screwdriver for screws, a drill press for holes, a saw for cutting, a mill for milling and a lathe for turning, etc.... to me, the fun part is thinking about the projects and designing them out on the drawing board. Also enjoy making my own tools, but you can just buy what others have designed for you, as you can always trade-off time for money. It's not the destination, it's the journey. Thanks for the video!

    This reminds me of the upgrades I made to my 3D printer kit, where I gradually replaced each new weakest component until I had pretty much built a new, better printer, just using the original kit as a scaffolding.

    @airgunningyup 2 ปีที่แล้ว +22

    for a cnc mill , rigidity is more important than all other factors.. The last one I made which is still use is box steel filled with concrete in a concrete base. 320 lbs , and the weak point is actually the spindle power which is 1.5 kw.anyway , excellent work finding all the weak spots in the design.

    • @stefandebruijn3167
      @stefandebruijn3167 2 ปีที่แล้ว +10

      Yea. (600/60)*0.75*3.1 mm = 23.25 mm^3/s. If you put in those numbers in fswizard, it's 0.02kW... that's really just peanuts for any 1.5 kW spindle. I have a nice, granite, rigid cnc here that does 20mm deep cuts with a 6mm endmill... If you punch that in, you still only get 0.53 kW, which means that the spindle will still be fine, that is: as long as the cnc is rigid enough...
      The weak spot in any cnc3018 is just... well everything... these things are just so flimpsy. Throw a back plate against it, and the little nema's won't have enough power. Upgrade the motors, and the excessive backlash will ensure that vibrations kill the router bit. Change to ball screws, and the side panels are too flimpsy to any real work. Replace the side panels with 15mm steel, and the y axis will be your next problem. Next, the motherboard is crap. The stepper drivers are crap... the list just goes on and on. At the end of the day, not much will be left of your router when you attempt to make it good...
      Really, the only thing good about these small routers is that they are so much fun to toy around with. I had one and enjoyed it quite a bit.

      @@robsproducts well u already have the main components from the 3020.. Mine cost about 750 total , But i used flat 20 mm linear rails on all 3 axis .. that was the majority of the cost ( 250-300 dollars) the concrete is dirt cheap , I used all the 6040 electronics, got a geared nema 23 for the z ( 45 dollars ) and used the 6040 spindle. The steel for the column was scrap from the garbage I picked up on the side of the road.Its probably more rigid than my 700lb benchtop mill , but these chinese spindles lack the grunt needed for heavy passes i can do manually on the mill. Hope that makes sense.. In my experience , the Z ( spindle mount ) rigidity is more important than the x aand Y, so u can go cheaper on those rails. I kept my 6040 running right to the end , to make brackets for the new machine.. then basically swapped the electronics over in one day.. so very little downtime

    Not sure if you touched on it or not, but one of the first things you should be making is replacement parts for all the support pieces that are still plastic. Especially now that you can machine aluminium easily. Replace the side supports, and also the 3-d printed backing plate. You should be replacing everything you possibly can with metal. I like that you changed out your slides for linear rails as well. Doing all your axes will make an improvement as well.

    As a machinist and cnc programmer, I see a common issue with hobbyist using the CNC 2018 , the clamps are not being used correctly. The clamps should be parallel to the top surface with a packer piece to suit. This will greatly assist in clamping as it won't vibrate loose and break the cutter like it did in you video, with the clamps at an angle, it will come loose and move, breaking the cutter.

    When using a router, it's important to try to cut into the material direction only (as when using it for woodworking), Notice the vibration and chatter when cutting WITH the tool travel direction. That is because it is trying to cut with the shaft/tool direction. The tool will try to climb. The shaft needs to cut into the material.

  • @Dutcharmytent

    WD40 cannot be used as a cutting agent, paraffin is better or best still soluble oil. Lubricants dull the edge of the cutter . If you lubricate a cutter it glides over and does not cut efficiently. Also your clamps need to be parallel to the table. I have been milling all my life and now retired. Just an observation to help you get better results.

    I'm in process of a hybrid upgrade following this video. I'm going with 2 linear rail sliders on each x axis rail but the $80 z axis. The x axis ball screw alignment was a bit challenging due to the tolerance stack but I heated up the backlash nut after everything was mounted and ran the axis back and forth to help it self align in the 3d printed mount as it cooled. The files all had to be scaled but that isn't that difficult. The thing that is less fun is that these aren't solid files and they all need to be meshed into a solid which makes them tougher to modify, but hey he did most of the work so its a small inconvenience. Next is to change over the Y axis to linear rail guides and extruded aluminum because its flimsy after the extension in comparison to the x and z now.. Thanks for the vid!

    Excellent! I'm just starting my upgrade journey with the newer Sainsmart 3020 Pro Max... My first upgrade was to add linear rails to the Y-axis and make it 400mm (now 3040). Next, I'm going to beef up the X-axis in readiness for a new Z-axis and bigger spindle motor 😃

    Excellent video! I have this exact kit that has been sitting in my 3d printer room unassembled for the last two years. I didn't want to put it together until I had some kind of plan to make it machine aluminum more adequately, Now it can be a really useful machine that can help me to create the long lasting and useful designs that I have been wanting to make out of aluminum. So the main issues are the X rails, Z axis and the motor (I knew the stock motor was garbage from the outset). You have shown a clear path to improve the most salient points while leaving the adequate parts alone. You have earned my subscription sir.

    You are still speeding up the video when cutting. It would be really nice to see the speeds and feeds that you used. One other suggestion would be to get rid of those Y access spaghetti tube linear rails and extend the bed across the edge of the main frame rails and use linear rails on top of those. Those linear rails on the bottom bend and cause all kinds of vibration. Having a solid steel bed adds a ton of mass and really helps the finish. I'm following a lot of what you did with my 3018. At about the same pace.

    • @ericinventor
      @ericinventor  2 ปีที่แล้ว

      Hi Timmy, at 10:50, 11:19, and 11:52, there are a few seconds of real time cutting that is not sped up. And yes replacing the Y axis using linear rails like I did with the X axis would be the next logical step for sure. I was happy with the results I was getting for now, but if I do more upgrades in the future, that would be the main next one!

    I am a trained CNC machinist. I went to college for manual machining and then CNC machining. I'm also a trained welder, fabricator. I have not been machining since 2009. I was a good machinist and then the economy took a downward turn & I lost my job.
    I'm on disability now and I am looking to use my education to make a extra income because of the economy being what it is. I bought the 3018pro for under $200 delivered. I'm use to milling metal and not plastic or wood.
    I'm learning how to turn my skills into a viable income to help me with the increasing costs of living, & I am so bored with life that I could scream! Honestly, I went from high performance go-kart racing parts, Jr dragsters & lawnmower racing when that became a thing, to living a sedititary lifestyle. I was at the end of my rope, figuratively & emotionally, with loosing family members & friends to death. I was in a Very Dark place & I needed a creative outlet for my emotions & my skills of building & creating things. I'm the try that will build something that can be bought already made ready to go. But I prefer to build my own pieces of equipment to guarantee that I will have the best machine for my money. It's a lot of work to reinvent a machine, but the rewards are well worth the effort, time, expense & the knowledge that the machine is built as strong as it possibly can be, given the size of the parts that make up the machine & the components that are used in the machine itself. Like upgraded bearings, bolts, materials and everything else that you can use to make your creation better than the commercial variations that are for sale to the general public. I'm definitely not your average customer & I demand only the best in my equipment selection. I will completely redo the entire machine sometimes to add better bearings, linear rails, high grade bolts & fasteners. When I'm done with the upgrades it's almost a completely different machine. BUT MY MACHINE, WILL ALWAYS BE 2X'S-3X'S BETTER QUALITY THAN THE BEST FACTORY MODEL!
    I know that I could just save up the money and purchase a New Professional Grade machine, but that takes time and money, both are in short supply at the moment. So I IMPROVISE, and create the best machine that I can using what I have, can afford & what will do the job I'm asking it to do. It's a Frankenstein machine, some parts are modified to make them work with a different companies parts, but it's a TRUE PLEASURE TO SEE YOUR FRANKENSTEIN MACHINE COME TO LIFE, & BE EXACTLY WHAT YOU'RE NEEDING AT THE TIME!
    NOTHING BEATS THAT FEELING OF A HOME ENGINEERED, PROJECT ONE GOES THROUGH TO BUILD A BETTER WORKING MACHINE AT HOME, WHEN EVEN THE BEST COMERCIAL MACHINES HAVE DIFFICULTIES DOING, THE SAME WORK THAT YOUR HOMEGROWN, SELF-DESIGNED MACHINE IS POSSIBLE OF DOING.
    The PRIDE you have, knowing that you built that machine and it works, BETTER, that it's Professionally Manufactured Counterpart Machine has trouble recreating the same product.
    There's more than 1 way to skin a cat! The same with machinery. The Professional Companies have pretty well designed machines. They cut costs where they can so they can stay competitive in the market. I'm not interested in competing with anyone. I'm just trying to make the best machine, with the most robust components available & using them to make my machine work better and last longer because I chose to go with upgraded parts from the beginning of the build. Why wait until it starts to fail to redesign the parts so they can handle the Extra Tourqe, Rpm's & the Flex or movement of the linear rails or support pieces. Take care of the items you feel are substandard to begin with, and save yourself weeks of time and misery trying to figure out how to make this piece not flex or not do something it's not supposed to do. A little preemptive thought and engineering will make the machine work better, faster, will increase overall performance and efficiency in your parts manufacturing and the quality of your parts overall. It takes some time to make the changes to your brand new machine and then there's the cost of the improvements to your machine build. BUT in the end, IT IS ALL WORTH IT. THE COST OF THE IMPROVEMENTS WILL PAY FOR THEMSELVES IN A VERY SHORT TIME.
