The cheapest $149 CNC 3018, cut and mill aluminum is now possible with 500 W spindle upgrade
HTML-код
- Опубликовано: 18 июн 2024
- In my previous videos, I used this CNC 3018 Pro to make some aluminum 3D printer parts. As many of you are interested in how I upgraded this $149 CNC to cut aluminum, I am going to make a series of videos to show you everything including the hardware upgrade, firmware configuration, using Fusion 360 CAD for 3D modeling and using Fusion 360 CAM to generate G-code for the CNC.
In this video, we will start with the most important part, upgrading the 500W spindle. You will see the detail process, what hardware and 3D printed models you need for this upgrade. I will also show some aluminum cutting footage so you can expect what you can get after the 500W spindle is installed.

This has got to be about the best newish RUclips channel on these subjects I have come across. I'm so very very impressed with your thoroughness and informed teachings and style, keep up the great work Aurora Tech!
Totally agree
Its a setup, look at the workshop and who lets kids play with AC voltage 🤔And who pays for all this stuff, there's a team hidden somewhere. And are they affiliate links in the description 🤨
@@NathanCroucher This is a very informative and well done video so I don't see how your comment and how and who created this video even matters.
@@NathanCroucher Anyone with half a brain should be able to deduce that. Doesn't matter: its about the content, and she does a GREAT job delivering it. Far better than MANY 4x her age.
@crozwayne Same here and best wishes to all decent people from Prague, Czech republic! 💪😏
Im 70 years old and its a pleasure to watch your great presentations. You appear to be about 10 years old, your parents must be very proud of you, I only wish I had been as smart as you at your age , Im not even that smart now ! Thanks for the great helpfull video and keep up the great work !!!
Holy shit, if I believed in having kids I would want one just like you. "Dad, I need a water cooling system because the CNC machine I use to shred metal for things I'm manufacturing is getting too hot, also we'll need to run a 240v line because the whole setup isn't getting enough power." a single tear of joy and pride would run down my eye if my hypothetical child said that to me and would do my best to make that happen, if it were in my power to do so. Your parents must be so proud of you.
Wise old people often say "You can't machine aluminium on a 3018", so it's great to see you just going for it and dealing with the challenges like it's no biggie. Cool as a cool thing.
Great walkthrough of the upgrade project, love it
Thanks for sharing your experience with all of us 👍😀
You do a great job of explaining, and an even better job of pulling together resources to make what you need. Excellent!
I subscribed because of the well-presented content. Thank you for taking the time and effort to put these videos together. Any information, tips, and tricks for this machine and others are greatly appreciated!
Your experience and clarity given your age is genuinely inspiring. You rock!
Thank you for your videos. Very well explained and informative. One of my favorite channels.
Thank you for all the hard work.
This is EXCELLENT content. The script is much clearer than any previously offered. Thank you.
This was an incredible video, learned so much and you're so calm and with a clean speaking, congrats
Great video. Thank you for putting so much time and effort into making this.
Brilliant! Thank you so much for this video!
This is by far the most informative video I've found on my new 3018 cnc machine. Explanation of the machine was very helpful. Probably the best youtube personality in awhile!!! Please keep making more content on this! Look forward to future projects!
Absolutely outstanding 👌 I’ve just got the same spindle setup thanks for the tip on the stepper as I’ve been thinking it’s not enough after feeling the weight of the spindle 😂
This is the video I need, very informative, practical and clear. I recently got into CNC and plan to get a 3018 with the intention of milling aluminum later on. I hope you make more 3018 upgrades in the future. You just earned a subscriber. 👍
This is soooooo well done. I've been 3D printing for a few years and am just now looking into 3018 or similar CNC, and this is by far the best series of introductions I've seen. Very clear, very thorough, very worth the watch!
been lurking around the net gathering info , finally got my 3018 a few days ago but have not run it... very good intro, easy to follow.
lookiing forward to more 3018 content, more power!
Great informative video, well done. I am in the process of carrying out a similar upgrade and found this video really helpful. Thankyou and keep up the good work.
Situation where you need two like buttons. Good job. Clear concise and straight to the point.
This is a very well done video. I've seen people gloss over the relay/emergency stop button and your explanation is MUCH more clear. Great job!
I've been looking at many videos on this subject. But, none of them cover the subject with such detail and useful information. Also the quality of the presentation is excellent!
I found your video last night while looking for a cheap CNC router for some projects I want to work on. First, your presentation skills are really, really good. It's clear that you know what you're talking about. Thank you for thoroughly explaining what you did. I'm seriously considering this solution because of you and your video. Thank you and keep up the great work!
excellent work. Seeing your iterative refinement is very useful.
Thanks so much for sharing. You are very informative and enjoyable to listen to as well. I get a kick out of knowing that a 60 year old man is being instructed by such a smart young lady. Especially when it's about tools😊. You keep making videos. I'll keep watching.
Ok I'm subscribed and hooked. Your parents must be very proud of the two of you, it would be nice to see a video introduce your brother not by name of course and understand what your brother does, what you do and what help you get from your parents in producing your videos I think everyone who's helping you do what your doing deserves some praise. I'll be building this in the future once I've completed my Voron build.
you scare me...in a good way. You are so articulate and present so well for what appears to be such a young age. Best of everything in your future. subscribed
straight one of the best video/tutorial's straight to the point no fancy words nor bloatware or old Dave from down the road, saying a million things in-between adding steps or crossing/overlapping information... Keep up the good work young lady, and of course your brother as well, behind the scenes, very thorough and to the point 🙂
I am thoroughly impressed, given your age. Not simply because of your intelligence, but the time it clearly takes to gain all this knowledge. Well done!
Well spoken and nice presentation. Thanks very much.
Great detailed explanation 👍🏾
I just subscribed to your channel. I am just learning CNC on my 3018 pro. I would like to engrave Al with it. You are a great instructor!!
What a great video.
Very glad I found your channel
Thank you. Very helpful 👍
Don't know how old you are, but I am impressed with your knowledge. Someone should be very proud of you. I am 68 and just starting into CNC .
Am putting together a CNC laser unit. I need to learn GRBL code also. Great video. Wish I had a granddaughter with your smarts.
Truly excellent presentation. She certainly has a future in communications
Fantastic video. Incredibly knowledgeable, well presented and informative. 👍🏼👍🏼👍🏼 🇨🇦
Excellent video. 👍
Im in, subscribing! Thanks for the info.
Her presentation skills are absolutely fascinating to watch.
Super informative! Great channel 👍
Thank you for your nice videos
Amazing video, so well done and the quality was fantastic! Do you have a part 2 to this yet?
outstanding presentation !!!!!!!!!!!!!!!!!!!!!!!
Brilliant! Subscribed!!
Fantastic video !!! At the end of this video you mentioned that you will be producing a video demonstrating the addition of a probe sensor to provide the exact location of the stock you are cutting. Please provide the link to this and other videos which demonstrate or explain the use of a probe sensor and 3018 class of desktop CNC machines.
Finally, thanks for all the great videos you and your brother have and continue to provide.
great video thank you for sharing
Nice explanation.
This girl continues to blow my mind.
Wow great video.
You and your brother are incredibly capable and smart kids. Just an observation on your video and someone may have pointed it out already, but your safety is number one. Always use tabs for profile cuts as some hold-downs such as double-sided tape or CA glue on blue tape might not be sufficient enough, especially when aluminum gets heated during the milling. That part that flew off was very scary and could cause some serious injuries. I know you put your CNC in the enclosure but that one didn't seems to be in the enclosure or at least it didn't look like it. Please be safe.
VERY NICE!
Two years before there wasn't much detail about this, i struggled to upgrade
FYI,The stiffness of the linear rods are not sufficient for cutting, i added linear ball rail , designed bracket myself and printed
Well presented detailed content, keep the good work
Awesome just what I'm about to do. You have my sub keep up the great work
Can you do a vid on adding a probe to the cnc
Liked this at least 4 times now..😐.. And I subscribed just as many times!..
TOP PRESENTATION..
Great presentation! Very clear, sufficiently detailed and an example for presentations on this topic. Keep going with this good stuff!👍👍
Hello Aurora and Helios, thank you for posting this video. Just to let you both know I’m 68 years old and I’m learning a lot from you two, awesome and cool. This is my new retirement hobby, it looks like a lot of fun. Keep up with the good work 🤗👏
Uh...same here @ 68 and retirement hobby. I feel like Benjamin Button.
I love your presentation - you guys are great. I had bought the same 500 w Spindle upgrade to my 3018 Pro and was searching for some help on RUclips for the installation. I literally bumped into your video and love it, I've watched it several times. I have a question about connecting the E-Stop and Relay - I can't see exactly how you connected those - can you please share which end of the Relay you connected with the E-Stop and which to the power supply and which posts you used - please??? Thank you in advance and keep up the great work...ml Colorado btw: my son-in-law is an electrical engineer who is going to help me come up with a way to connect the spindle through the Grbl Controller so that the software (Grbl Control Candle) can control spindle speed - when I figure that out I'll share it with you if you're interested.
Brilliant. Ones the new spindle is working, you can then also machine a new mount out of aluminium, in case the ASA part doesn't hold up in the long run
I look forward to seeing your next video. I have not had my 3018 for long and it's interesting to see what it can do with some upgrades. I think I will need fusion 360 as at the moment I am trying freecad but it is very hard to learn. Excellent video again and thank you for sharing.
One thing to be careful of once you get used to a CAD tool you'll end up sticking with it like glue so choose wisely. I use 360 it's fairly intuitive it can be a little buggy so make sure you save a design early on it has auto save but it only works after you've saved for the first time nothing worse than losing hours of work because you forgot to do a first save, like I say it's great but it's also tied to a company so they could change the license rules anytime they like. Free CAD is definitely less intuitive but no-one can just change the license rules on you.
Thanks for the advice I have been caught out by autosave? before.
I will probably have to return the 3018 as the fan on the laser is faulty and makes the squeal that fans do when the bearings are shot, the seller thinks that it is normal! so I will have to get ebay to step in. The laser has not done more than 2 hours and if the fan won't keep it cool it will fail.
@@thingys-rd7id never really used a laser if I was going to get one I'd probably go all out and get a tube laser as I'd be more interested in cutting than etching if only I had the space for one.
Just earned a new subscriber! When will yall upload the video for the limits switches and the probe?
I'm amazed that a 10 year old can explain upgrading a CNC so clearly.
Is she really 10?. I don’t think so
ahhh a child an adult can listen to....presentation is perfect..... we don't even see your age....wow wow quality quality
Hi, Nice work.. Choke up on your tools to minimize vibration. Keep going..
Just curious, how old ar you two?!? Your tutorials, presentation and technical knowledge is impressive! Best channel for these low cost machines. And awesome job about the price informations and explanations why you choose what.
Very helpful video.
I did the same upgrade early this year, but I didn't upgrade to a bigger stepper motor. I read the control module manual and it mentions something like: "the maximum motor currents for the stepper motors used must first be set on the control module using the appropriate miniature potentiometers" and I was afraid that I had to make changes on the control module and I am not savvy when it comes to that.
Is it necessary to make changes to the control module when you upgraded to a Nema 17 40-48?
Can't wait to see your next video about the limit switches and the probe. Thanks.
I went to school for cnc and I didnt know you got more torque at higher rpms, super cool
Hello! It actually depends on what kind of CNC / spindle. For this kind of low-priced spindle, you get more torque at higher RPMs. But, on a more expensive CNC, the constant-torque spindle can maintain the same torque at different RPM. Thanks for watching! :D
You can try Googling "Why does the torque curve drop off at low RPM" and you will probably find some better explanations.
@@AuroraTech What a champ!
Hello great video. I upgraded the stepper to the larger stepper motor but now it just shakes and I have to reset the machine. Its as though it needs more current. The smaller steppers still work first but this new one almost causes over current
Thanks for the great video. What do you think about using a dremel 3000?
I keep finding myself referencing this video as I'm just starting out using my 3018 to cut aluminum and it's incredibly helpful.
Do you happen to have a wiring diagram for the 24v relay by chance?
Great video! Does anyone know what the stepper motor connectors on the board are? JST? Molex? Thanks.
Are you going to do the video on the touch probe and limit switches? very interested
Again a great educational Video you guys are just a treat to see. Yes I want to get that Mill, I use F360 already for 3D Print parts and I have a Cr 10S Pro V1 printer I have many of the same tools you do. Now I need that Mill. I need to make train parts for Motor Mounts and Steam Engine Linkage. I wonder if Aluminum can be Polished and buffed to shine then sealed to stay shiny? The Linkage is only 2 or 3 mm thick. Will it be stiff enough as these main linkages are used to drive all the wheels. If I sent you a part can you assess the process to make it for a Project, If I help pay for your time???? Dennis
Hello. I have been searching for days to find a definitive answer to which terminal is hot or live and which is neutral. I've read a debate about it doesn't really matter. That was in comments for one of the only videos where the author actually used correctly colored wires (for UK). He identified the terminal on the right as the hot (brown) and left as neutral (blue). That is opposite of how you have it. Any thoughts on who is correct?
After watching your video, I am inclined to believe you know better than the old man who made the other video. Your video is possibly the most awesome I have ever seen on youtube. I will be watching every video you have made!
I wonder if you're still planning to do a video about end stops and limit switches for the 3018?
I'm curious: is there any support by your parents?
Video is amazing as always ;-)
When are you going to do the video with the limit switches and probe?
Did you use any resistors on the cables from the control board to the relay?
Where is the video with limit switches installation process? Anyway, amazing videos!
need to hook up a blow Nozzle to push those chips away, of cores a better option would be cutting fluid nozzle which you would want to use a non conductive cutting oil, and run it at a high enough pressure to push the chips away from your work piece.. this will improve the accuracy and over all look and quality of your end product, will also extend the life of your end mills and spindle by them having to work less to cut
Hi. You video are very informative. Thanks you. I new to CNC. I'm looking for a cnc that able to mill aluminium. My budget is $1000 can you recommend something. I'm very handy so some modifications is fine. Much appreciated
Hey, I've something similar set up. With the relay connected without any resistors, is it erratic at low speeds?
wow that's great video i love female engineers smart like you
How’s the upgrade and motor holding up did it finally burn out yet?
Hii, where i can buy the relay?
WHAT IF MY UPGRADE PS IS 24V OUTPUT, BUT THE ORIGINAL ONLY HAS PORTS FOR 12V AND 48V.. CAN I STILL RUN A LINE TO IT? WILL ANYTHING FRY OR BLOW UP?
got a 2hp router I'm putting on my 3018 fox alien I just ordered, 28,000 ripp em's
Ok im having an issue. How do i connect the replay without the emergency stop.
How long did it take
Cutting Aluminum is going to be a game changer!
I wonder can it cut copper and/or bronze.
You should be able to cut copper brass might be challenging though. I've looked at this machine before but always thought it was just to weak for any serious usage with after this video though I'll definitely be building one.
@@Mrtickleberries I would love to cut some hot leather stamps with this. Heck leather stamp are about the same price as this machine being able to make my own be nice.
tbh it looks worse then my stock spindle ... (agreed i saw way worse cuts on other 3018s but still..)
btw for everyone wanting an cheap and easy upgrade, the spindle is not the problem on these mashines... well, it kinda is but not the power but rather the floppieness of the connected ER11 chuck. take a fitting ball bearing onto the shaft of the ER11 collet, print a part that holds the bearing as stiff as possible to the motor and see how much it improved.
PS. for everyone wondering, i tested, well.. rather experienced that aluminum is no problem for the spindle motor even with a 5mm DOC @ 100mm/min and even V4A steel worked for the motor... main problem there was the overall stiffness of the mashine but the motor had no problem with 2mm DOC @ 60mm/min (granted it looked and heard horrible due to missing stiffness in frame and coupling to ER collet but it did cut the pipe in one go ....)
WOW how old are you? your a generous God bless you
Hello, good afternoon, thank you for your attention and your response to my previous query.
I have made the update of the 500 W spindle as indicated in your videotutorial and it goes great, except for the part where you replace "STEPPERONLINE Nema 17 Stepper Bipolar Motor 2A 59Ncm (84oz.in) 48mm Body 4-lead W / 1m Cable and Connector compatible with 3D Printer / CNC "
I would like to ask you another brief query regarding the above, and it is that I have acquired another nema, which has two axes for the purpose of adapting a manual knob, "Nema 17 stepper motor, double axis, 48mm, 17HS8401S, 1.8 TO". but this one doesn't work. a greeting.
problem solved. a greeting.
Did u have, schema of electricity?
At 11:47 what is the spindle speed?
Great Video - I bought the Comgrow . Updating to the 500 watt spindle and relay that you suggested. What are the three wires that are going into the input of the relay. I have the two that came from the spindle. The green light on the relay comes on when I give the start spindle command but does not trigger the relay. Any ideas. Thanks in advance.
The green light is ON means the signal line to the relay is connected correctly from the motherboard 24V terminal. Please check the power supply and the spindle and see if it connects to the relay correctly:
1. The positive of the spindle and the positive of the power supply are connected directly.
2. The negative of both spindle and power supply connect to the relay, when the signal is triggered, the relay will connect them together.
You can also watch and pause at 8:24 of this video for wiring, if you don't have the emergency button, just ignore it and consider that is the spindle.
Great tutorial by an elementary school student
Hello good morning, I would like to know if it is possible to have the wiring diagram.
Besides, I would like to know, if on the "Control Grbl" board of the CNC 3018, the terminal, "0-500w, power 048v" is used, and in that case, what would be its purpose, and what type of connection It would be done?
Thanks for this great contribution.
Hi, the 0-48v terminal on your board is a MOSFET which works the same as the relay in my video. Since my board doesn't come with an extra MOSFET like yours, I have to add a relay to control the external power supply. But I am not sure that 0-48V terminal is OK to control the 110V power supply, or you can consider a brushless 500w spindle which cost more, but make less noise and uses a 48V power supply.
amzn.to/3yna7TD
@@AuroraTechThank you very much for your attention.
It has been a great contribution. I had also thought of replacing the board with this other GRBL Voltage Regulator Control Board, 4 Axis Stepper Motor to add Mini Woodworking CNC Router, 4 Axis Rotary Axis Engraving Machine.
A greeting from Spain.
