You could upgrade this a lot more now you have it by replacing all those plastic pieces with aluminum replacements, that'd make it a lot more rigid :)

@MikelNaUsaCom Рік тому

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!

@joeemenaker Рік тому

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. I've got a 3018, too, and I guess it's about time to start giving that the same treatment.

@pyro1596 Рік тому

I did the same thing with my Tronxy X5S. Had military money every month and just threw funds at it. The only things left over from the original printer are some of the frame and the motors. Everthing else has been replaced and upgraded. Sad thing is, it still isn't working

@dekutree64 Рік тому

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 Рік тому

Interesting toolpath sequence... That sounds like it could be much faster than continuously going around the tooth profile. Ill have to try it next time! What CAM software do you use?

@dekutree64 Рік тому

@@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 Рік тому

@@dekutree64 Wow, how does one write Gcode with C++? Is there a package or tool that is made for writing gcode?

@dekutree64 Рік тому

@@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.

@richkay228 Рік тому

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 11 місяців тому

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.

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 8 місяців тому

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

@user-tf1oo9rj6u 5 місяців тому

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.

I have followed your description and ordered a 3018 Pro and all the other stuff now, allthough I live in Europe, and it was more practicel for me to find the parts closer. I don´t know if the upgrade z-axis will work, it would be far to expensive to get it from Canada, so I have found one that looks kind of ok - we will see.

@airgunningyup Рік тому

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 Рік тому

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.

@rvandope Рік тому

What would you say the total cost to build youe cnc was in the end? I just got a 3020 Pro Max from Genmitsu but anticipating some upgrades pretty quickly.

@airgunningyup Рік тому

@@rvandope 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

I enjoyed watching this because I went through the same learning curve for the exact same reason ...and I was called ScooterFaster. I watched you learning ... Keep the hold downs level and very tight for example. My mill was 5 hp and when you crash or chipweld a 1/2 inch carbide even at 2000 RPM it is very exciting. One thing I couldn't tell is what specific tooling you were using. Try some premium coated 4 flute solid carbide bits. Money spent here shows up bigtime. P.S. My thing was twin (2) brushed or BLDC motors with 400 amp controllers. Fun.

@jeremykukowski3065 Рік тому

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!

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.

Have you tried using a larger collet and tool with the 500 W spindle? it doesn't seem like the 500w motor is struggling that much, and most of the impact appears when upgrading your tool usage.

@ericinventor Рік тому

To be honest I didnt quite perfect the vaccuum system, theres two annoying aspects: one, your vacuum system needs to be close enough to your parts to capture chips but not so close it interferes with the part your cutting (especially in the z-axis), and two, the main solution to that problem, which is like a brush curtain around the endmill, prevents you from actually seeing what your cutting, which for a not so reliable cnc like this one, is quite important. So my goal was to get good chip clearing into the vaccuum while still being able to see the cutting and also not interfere with the part. I got close but didnt quite reach that goal yet.

good job at the end, the cutting is smooth. Probably because the Makita has speed control.

Excelente trabajo, amigo que parámetros de cortes utilizastes para cortar el aluminio, la velocidad de de avance y en qué velocidad pusiste el makita?

I had a fet tries at my Z axis too. In the end I went with 10mm rods, rod sliders and I vacuumed a carbon fibre clad and epoxied cnced wood plate to hold my water cooled spindle motor. Only issue is my X axis is not ball screw, it's belt so it's a bit more flexible over it's 1.8m travel. Will cut aluminium but not ideal.

Great video thanks! The "Warts and All" honest approach is really useful, compared to the "I waved a wand, and this masterpiece appeared" style. Looking forward to browsing your channel! :o) Liked & Subscribed.

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.

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!

Nice video, thinking of buying a cnc myself. Already have a makita router

@Hagis2k Місяць тому

Just bought the 3020 chinese cnc router, I shall absolutely go after your ways. Shall buy a small Makita router to it, as my plans are to cut aluminum just like you, thanks for this video it confirms all my thoughts about the linear rails (roundbars) being to flexible. I been looking at linear rails for a while to modify my 3D printer with 2 lead screws, and 4 linear rails in each corner, I have the creality ender 5 s1 and getting the buildplate adjusted is a real b**** I shall add a 5th point where I can adjust the center too. It is really nice that you can utilize the 3d printer to make parts for the cnc and vice versa :) You gained another subscriber too, have a great day!

Could you please make a follow up video and more part making and testing such as tollerences and accuracy. Would appretiate it thanks.

How much have you spent so far in upgrades and how much time? Just curious

@SeanChYT Рік тому

I've also upgraded the heck out of my 3018. Had a lot of fun doing it, but it would obviously have been much smarter of me to buy a better quality CNC to begin with (or parts to build one from scratch), and much cheaper as well when you add ***everything*** up.

@SmallSpoonBrigade 8 місяців тому

I'm waiting to get mine from Monoprice, interestingly right now they're selling theirs for under $200 for what appears to be basically the same machine. I was planning on using it for plastics, but if I can upgrade it for aluminum, that would open a lot of opportunities in terms of making money to afford a better machine. I'd love to have a CNC plasma cutter.

Well I have wanted to get into CNC machines for a minute. But due to a lack of a decent budget I've avoided them altogether. My goal is similar. To use a CNC machine for a few projects (( mainly motorized bicycle disc brake adapter, a chain tensioner and other parts ))

@charliebrown-np1tv 3 місяці тому

great job, so it would be easier if i just have you put one of those together for me right? lol you already know what to buy and how to put it all together. love your cnc. that would be good enough for anything i would need

@seebl3273 Рік тому

Very nice content, congrats on your selfbuild Frankenstein. But to be honest, the cheaper and more comfortable way would be building on of the half printed ones. For example the TopsCNC.

Nice. I have a bauer harbor freight palm router. I know what I’m about to do with it! Thanks for the idea brosef. Sub earned.

@capthowdy126 Рік тому

i really want to do this to my little 3018pro but the more i messed with it the more i felt like the hole frame was to flimbsy to do what i wanted so i took my focus off the 3018 an put it toward small benchtop mills an i have a wen 33013 now an it eats aluminum or at least it does way better than anything ive ever owned b4 an the finish is great so now im back after seeing a bunch of the newer 3020 machines cause the mill is great an is really enjoyable to run but id like to have it powered by stepper motors so when i want a circle cut it can do it without a bunch of extra setup required so i went back looking at the 3020 machines but i still have my old 3018 an a bunch of linear rails already in the spare parts bin so i may as well try to make it do something an if i can get it to cut aluminum like u show in ur video i would be extremely happy but i think i can pull it off by making alot of the parts my self since i have the mill an once i get everything on it lined out like backlash in the handles it will be converted to cnc. is there anywhere ur sharing ur work for the files u made an a parts list.

@vdsmade Рік тому

@swamppifi6186 Рік тому

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.

Noted! Thanks for the tip, a couple other guys commented this also.

@nickolassaavedra1737 Рік тому

Quick question regarding bits, what bit are you using for milling aluminum? Are there small bits that can mill aluminum if they're strong enough? Or is that just not very realistic without a lot more rpm's than the 30,000 the Makita can put out?

@headshot6959 Рік тому

A quick question - would upgrading the router have negated some of the chatter in the rails/axis? This is an inspiring video btw, about the best CNC upgrade journey I've ever seen.

@ericinventor Рік тому

Having higher RPMs can definitely help with smoother cutting, so the makita cut better than the 500W chinese motor, but the most important thing is machine rigidity

@Arnor2207 Рік тому

hey, would you upload a guide on how to step by step? What about one to cut steel? (even if it is slow)

Just ordered mine, going to increase the size to 300mm by 1100mm, and use it to rotor foam for lost foam casting.

@garymckenzie9307 2 роки тому

Hi, great upgrade - I have a 3018 Pro I was going to bin because it was useless. Now I'm going to do as you did! Did the Y axis require any upgrades? Any mods to the anti backlash springs/nuts? cheers

@ericinventor 2 роки тому

I didn't touch the Y-axis, although I have had to replace the 3d printed bracket that carries the ant backlash nut when it cracked once. I think it would be relatively easy to span two more beams under the y-axis and mount two more linear rails to replace the existing cylindrical rods, but I was able to get pretty good performance without it.
