In this video, we will make some aluminum parts with this super cheap CNC 3018 Pro for the Sapphire Plus CoreXY printer. If you’ve watched my previous videos, this printer has a few minor issues, but considering that it costs less than $400 and has a very sturdy frame, it actually has a lot of potential. It’s able to print at 150mm/s with pretty good quality. But, when I try to print at over 200mm/s, the hotend couldn’t melt the filament fast enough. So, I decided to upgrade the hotend to a E3D V6 Volcano which should do a much better job than the stock one.
After all upgrades, the total price of this CNC machine is $230. I also made an enclosure, as this machine is quite noisy when it cuts things. I used less than 4 meters of 2020 aluminum extrusions, which cost around $35, 2 pieces of laminated MDF from Home Depot, which cost $12, and one piece of a one-eighth-inch acrylic sheet and some magnetic tape, which cost $30. So, the total cost of the machine with the enclosure costs less than $300. It actually doesn’t look too bad, but the most important part is, can it really cut aluminum? Let’s find out.

@claudelefebvre3076 2 года назад

one thing that would help , it is to put some cutting oil on the tip of the cutter while cutting the parts, it will cool it down and help the cut , good work and you can tell your brother that he is doing a good job with the videos , you can also tell your parents that they are raising two great kids 👍 , and from what i saw in the comments lower , sois tu lis le français ou tu utilise translate , mais ta réponse en français me faire dire que que es une personne ouverte aux autres langues et c'est admirable de ta part, bravo ! merci de partager tes vidéos 🙂

@cacaokingdom3122 2 года назад

I have one of those same CNCs and just purchased the 500W spindle. haven't mounted it yet though. Also have the limit switches and planning to get them installed. While the 3D printed option for the mount allows the most flexibility, one option is to mill a new mount using wood instead. You won't have it go soft from a little bit of heat! Maybe figuring out how to mill one later from aluminum would be best though even if done as a couple layers/pieces.

@duncanmarks1590 Год назад

hi, very good presentation with good coverage of the limitations of small machines and the issues of using "cheap" tooling bits. bye Duncan

@bigwendigo2253 Год назад

You’re awesome! With the spindle heating up, I’m surprised you didn’t use any cutting oil. Anyways I really want to get one of these and slap linear rails and a larger spindle (I’ve seen some people use dremels or makita drills for the spindles and get really good results) Yeah, there are a lot of upgrades you can do on this.

Awesome video and great instructions. Little advice... make sure your tool is as short as possible. Get a shorter endmill and put it in the spindle as far as you can. If the Tool can't reach the desired depth, just move the whole spinbdle motor down in Z and your finish will be a lot better.

I came here looking for the CNC but saw that we have the exact same Sapphire version. I cut the Z lead screw tops with bolt cutter and printed a plastic hotend mount and fan shroud for v6+volcano (again same choice.) Otherwise for Sapphire Plus, if you have the version with Z screws on sides, volcano block collides with the screws.

@aps3000miki 3 года назад

Fan-Tas-Tic. Amazing how much experience you show. If you want a job in the CNC industry, call me. You can start on Monday. Besides, here are a few tips for your cheap machine alu cutting: Always use single flute endmills for alu. Even cheap ones will do a good job and greatly reduce the stress on the spindle. Always use ramping (spiral ramp) to enter the material as well as for cutting and also try toroidal milling. These precautions will help your underpowered and flimsy machine to hopefully get useable results. You also need to be careful not to go too slow as your chips will get too hot. The plastic spindle mount is a bad idea as it retains the heat and supports heat build-up. Make one from alu, it will work much better. I just admire your videos, you have so much knowledge and your presentation skills are great. But even better, your video preparation and research are tops. Am sure your brother helps you a bit. You deserve 100000 views and you will get there.

@cacaokingdom3122 2 года назад

The actual mount that holds the spindle is aluminum and comes with the spindle. The issue in this case is the Z axis carriage that it attaches to. The one that comes with the system is integrated into the original spindle mount so has to be replaced in order to mount the more powerful spindle. The 3D printed option is pretty common since it is often readily available. However as they discovered using a lower temp plastic is bad. Most approachable initial option would be to use the system to mill a carriage from wood, perhaps in layers that can be stack laminated together. Using that, the system could run the higher power spindle and be used to mill an aluminum option. Another idea would be to add more active cooling to the spindle mount, maybe just in the form of a fan blowing on the spindle mount to help bleed off heat.

@dahlbergt 2 месяца назад

Very well done! :-D

@JonBergacs 2 года назад

Being that i did this. I can confirm increase your speed, reduce feed and i have run up to .015" deep. Have you ever tried any coolants? And you should move your X and Y to start position then run rapid to .100" above. Start spindle and move Z last to start cutting. This prevents dragging over the stock. Lastly you really should spot the hole before drilling and use same spot drill to chamfer the edges after. To remove some machining marks using fine grit sandoaper can give you a nicer finish.

@lawrencecole6527 3 года назад

You are kidding me with that using the tool as a probe!! Wow.

@scottwood9181 2 года назад

You wouldn't be the only one to cry about breaking expensive bits. I get carbide burrs for cleaning up welding projects and occasionally need to grind an inside corner. On a high speed rotary, that's dangerous and you have to be very careful as any 'skip' will quickly multiply as it careens off the inside walls and usually breaks the carbide burr sometimes sending pieces of it or the stock flying. But if you manage to escape flying bits, you still have to sit and cry over a $30-70 burr laying in pieces across the garage floor.

@davepaturno4290 Год назад

Also, you may be able to use a shorter windmill and increase depth of cuts.

@lawrencecole6527 3 года назад

Do you know about chatter? Chatter happens when there is not enough material for the cutter to cut so it pushes passed the material leaving a smudged/melted look. You can fix chatter by decreasing RPM or increasing Feed Rate. Also increasing rigidity will help prevent chatter. Hard deal for your situation. Try less tool stick out, better work holding, and less than 100% step over for your tool path. This is a make believe number but maybe with say 3% stepover the motors can handle full speed to utilize full rpm to avoid chatter. Maybe try a super short tool with insane number of flutes. Have fun!!

@peerrucke2599 Год назад

you need to build some cooling apparatus for this thing, better cooling milk than air. You also want a real Wolfram-Carbid bit which is aboz 25-30 bucks for a standard size. I think this machine is amazing. trust me this thing can do more than 0.1mm depth in aluminum given a good bit and proper cooling. Everybody can be an engineer now.

Thanks for the great video. I’d love it if you could buy one of those cheap rotary add ons for the 3018 much like the Snapmaker has but for a fraction of the price (not the roller type). Is it even possible? I’m assuming you’d have to raise the entire hight of the Z axis?

@eurisko84 2 года назад

As an engineer and hobbyist, bravo! Fantastic work the two of you. Excellent presentation method and writing. I would highly recommend using coolant/lubricant for cutting aluminium with this machine. Although technically not required DC for more expensive machines, this hobby cnc needs all the help it can get. Any lubricant is fine, but even just using something like water or ethanol mix helps dramatically. Just be careful and it will be a little more messy. Surface finish will be brilliant.

@Thedamped 2 года назад

Is it a reasonable concern that water ethanol would catch fire during use?

@eurisko84 2 года назад

@@Thedamped Usually the mix is around 60% water to 40% Ethanol, so no, the mix is not flammable. Also aluminium is a really good conductor of heat, and chips are not hot enough to create any risk of igniting the mix. Finally, these machines are cutting such small amounts with low feed and speed rates that the chips that are produced are more of a powder than actual chips.

@Thedamped 2 года назад

@@eurisko84 Thanks. Good to know. Though that mixture is definitely still flammable. I know from experience that 50% ABV will burn for quite some time while the ABV is constantly falling. I found a source that confirms flammability at least as low as 24% ABW: Flammable Liquids and Class 3 "...the dissolution of a miscible flammable liquid in water affects the flammability. For example, pure ethanol will flash at 12.7°C; a 70% mixture by weight in water will flash at 23°C; and a 24% mixture in water at 60.5°C." After reading a bit, it seems that fires are pretty common anyway so something you have to mindful of when CNC routing, especially when dry cutting wood. Which thinking now, seems obvious that the most common thing you cut is also flammable. I found other sources that back up your suggestion for using it as a coolant/lubricant on aluminum, but warn against using it in ferrous materials that can produce sparks. So also comports with what you're saying. So it's probably safer using ethanol to cut aluminum than dry cutting wood. I'm still getting my feet wet with this. It seems that CNC routers really need supervision. Apparently they are the most common cause of fires in machine shops. Have you ever had a fire? What all do you cut?

@eurisko84 2 года назад

@@Thedamped I should have been more clear, yes, it is still flammable, but less so than pure ethanol/methanol. Also do not aerosolise the mixture, only and use a direct jet or injection method onto the part. I use a small spray bottle on a single stream (not spray) directly at the part, whereas I have seen people use misters or the like, but I don't like this method at all. I cut 95% of my parts in aluminium and small templates in MDF, but you cannot use any lubricant on wood or MDF. But you are correct, it is a very dangerous machine to leave unattended, and as per all machines, shouldn't be left to run on its own without supervision.

@Thedamped 2 года назад

@@eurisko84 Oh okay, interesting. Thanks.

@Kyokahnn Год назад

I think you could've made an aluminum bracket for the spindle. Or even wood. For aluminum on a cheap CNC: carbide single flute endmill (cheap ones work ok, upgrade without breaking the bank: Yonico brand), adaptive cutting on fusion360, adapt an air assist with a cheap compressor or dust collection or both. Finally if you have some more of that nice aluminum, replace the plastic parts of the machine and upgrade the steppers to high torque n17 (the board allows a bit more amperage, just add a sticky heatsink on the drivers) I realized this is old, so just leaving this in case anyone else is getting one of these machines.

At 4:47 minutres into the video you go through a sensor probing routine to tell the CNC controller where the "Z" home; "X" and "Y" positions are relative to the piece which you are machining. Could you please provide the commands for the g-code sub-routine or macro that you used to accomplish this ? Also what software are you using with this CNC configuration ?? I'm new to dekstop CNC milling and 3D priniing and have found your videos to be a most valuable resource. Please continue producing these great videos !!!
