- In this video, I upgrade the spindle motor on my 3018Pro CNC to a 500W Spindle.
A Quick Warning!!! : If you try this modification for yourself, make sure to tighten the screws at the front of the mount after operating your cnc for a while. I didn't do this on mine and the motor became so lose that it got pulled out of the mount and drove itself into the aluminum plate. (Since I was there watching the CNC, only the end mill was destroyed and the CNC is ok, but it's best to avoid this in the first place)

Ah yes, the 32 subscriber reward. The wood play button
Exactly!
😂 I love it bro 😎
Well done video! Just picked up a 3018 CNC, this will likely be one of my first mods. Keep it up!
Thanks! I hope you find using it as fun as I have!
That new spindle is a good unit , I bought the same one and added it to my 4018 cnc , haven’t tried to cut aluminum yet but it’s great for wood and plastic 👍
Nice, Let me know how milling aluminum turns out for you!
Carbon Coil waiting for better clamps from overseas supplier don’t want metal flying all over the place 😉
I wish when you were comparing the speed of carving you mentioned the actual values. I am trying to CNC soft aluminum and looking to upgrade the motor on the new 3018 I got. is this still the best upgrade you recommend?
Nice work!
Great job. 👍 Like my spindle in my home
Sooner or later all of you who has that 3018 CNC will crave more and even build your own just like everyone else here on TH-cam LOL!!!
The 3018 was absolutely a gateway drug.
Hi there, great video, I have done this upgrade to my 3018 the only difference is I used a different mount. I did use the one you have initially and then changed to this one on thingiverse (thing:3645875) you get the 10mm work height back that you loose fitting the 500watt motor and it holds the motor more securely. It’s a bit of a pain to fit but I found it to be worth the effort. Just thought you might like to try it.
Seems like a good idea, Might try it in the future.
I want to do this upgrade soon. Just got my 3018 today.
Cool video cant wait for more
Thanks!
My 3018 Pro spindle mount does not look the same. The rods seem to be pressed in. That mount you have looks like the one on the 3018. I'll keep looking for now.
What was the new feed rate compared to the old one?
Hi good video!!
regarding the wiring, could you give me more details of configuration. If possible a video on the wiring setup would be amazing
Thanks again
I wired the spindle motor to the motor out of the motor controller, supplied mains power to the input of the controller, and plugged in the included potentiometer to the motor controller. There is no connection between the controller board and the spindle motor controller, I adjust the speed/turn it on and off manually with the potentiometer. The rest of the wiring for the CNC was left untouched.
Thanks for vid and the link to the mount model.
No problem 👍
Recommendation 3D print a vacuum head on the housing of the drill bit so it has a constant suction above the work item 😁
Yeah, something like a dust shoe. Could be something to try in the future.
Did you just run straight 110v into the controller for power?
Also, there are those terminals labelled on/off - I wonder if that can be connected to the stock controller (where the old motor was plugged in) to provide a CNC-controlled power state.....
Yep, 110v AC for the power connection. The on/off most likely is just to be connected to a switch and not powered. But, you could hook a 12v or 24v relay up to the spindle out and then have the relay switch that on/off connection.
The power supply/potentiometer on it is mains referenced. Be carefull with this power supply. I use an optocoupler to set the rpm via PWM. This works quite well.
Not a bad idea, I might try implementing this change in the future.
@@CarbonCoil Not sure if it's possible with your motor but this guy Minh hooked up PWM wires from the old board to the new motor and it worked. He controls rpm with software. th-cam.com/video/Vho_tGuLqd4/w-d-xo.html
PS: Later he did a jumbo-upgrade and used a hand-held router as the motor.
Why didn't you mill a new bracket?
Hello, I upgraded my 3018pro with the 500watt motor and the spindle holder you use, However, the spindle now comes forward a bit. Do I need to change anything in the GRBL settings now?
Nope, you shouldn't need to change anything because you usually set the zero point in software every time you do a carving anyways.
Is the motor speed only controllable through a potentiometer or can it be controlled through g-code as well?
Theoretically it can be set up to be controlled through g-code. I just don't know how I would go about doing that. Could be a future project to look into!
The z axis bearings are too far back on the standard part, you can move them forward around 3 or 4mm while it soes not sound like much every millimeter you can reduce the leverage makes a good deal of difference in the ridgidity, I find that with a little bit of thought the whole Z axis could be moved back toward the collums around 7 or 8mm, which would make a huge difference in reducing chatter
Thanks, I might try this.
How long did that carving actually take? Did that new spindle speed up the cutting speed?
Don't remember exactly how much faster, but I could increase the feed rate much further before I ran into problems with chatter.
Congratulations what software do you use to make your parts on the cnc3018?
I use an online software called Easel. You can find more in depth on this topic here: th-cam.com/video/NNnxV0NLdXE/w-d-xo.html (Although I'm looking into using Autodesk Inventor Cad and Cam in the future.)
@@CarbonCoil Thank you very much.
Hey again, how did you get the middle bronze thread thing out ? I got the bearings out easy enough but the thing in between seems stuck
I think I was able to just hammer it out if I remember correctly
@@CarbonCoil Okay thanks man, i'll shall just hammer away!
what type of filament do you used ?
I used PLA, but I would suggest using something stronger instead such as ABS or PETG
Great video, I'm using mine as an engraver, but can't seem to get the right depth for letters, any suggestions, please TIa
For engraving I just do trial and error to find the right depth. I would suggest taking a piece of scrap wood and trying different depths on it. Start very shallow, barley touching the stock material, and with very small increments go deeper and deeper until you find a depth that looks good with your bit and material. I usually use something from 0.01" to 0.03" for small letters/text.
@@CarbonCoil Cheers thanks for that I will primarily be using acrylic plastic, will the principles be the same? would you recommend changing the bit?
@@richarddalton2052 Yep it will be about the same. If you are just doing engraving, you can keep the V-bit. However, if you are looking to make larger cuts with another end mill, I would suggest a single flute end mill for acrylic such as the one I use in this video: th-cam.com/video/cbQ1ZffEBlU/w-d-xo.html Let me know how your project turns out!
hello friend could you show me the parameters of cnc 3018 configuration list? spindle original
Double Nik here you go skillfasr353.weebly.com/cnc-3018-grbl-settings.html
Could this cnc with 500w engrave painted die cast aluminum boxes?
It should be able to. I recently made a video on this very topic of trying to machine aluminum with a 3018 CNC. You can check out that video here: th-cam.com/video/kODvQ1fMYXU/w-d-xo.html
Good job! But there is a 800W spindle with 20000r/min on Aliexpress. The price difference is not too big, and I think to buy one.
Thanks, I'm glad you found this video useful and are trying it for yourself!
@@CarbonCoil I did not buy this spindle while, because I have no any free time for my CNC3018.
Hello, I also have such a motor (48V). It was working before, but yesterday, while scraping wood, the motor had a hard time and suddenly stopped. Now it doesn't work at all. I measured it with a multimeter. There is electricity (48V) at the output of the PWM driver and the positive and negative terminals of the motor are powered, but the motor does not move. What do you think might be causing the problem?
It sounds like the motor might be damaged, if you can open it safely check the brushes and rotor and if they have sustained damage.
@@CarbonCoil Thank you for your answer. The tip of the charcoal is burnt. I sanded it and reinstalled it.
@@beykana I'm glad you solved your issue!
Is there any advantage too using a brushless motor instead?
Not really, brushes will wear out after a long time but most spindle motors are just brushed dc motors.
@@CarbonCoil There are two potential advantages.
1) brushless enables real speed control instead of just the power control you have with brushed motors (that don't have speed feedback).
2) brushless should have much greater torque at lower RPMs.
whether these potentials are exploited by a particular brushless controller remains to be seen.
Do you seel the spindle mount? Let me know
Hello. Could You send me a design of new support (red color) please

How did u know what speed for the spindle to start carving at?
I didn't really know what speed to start with and I didn't have a way to measure the speed either even if I knew the target speed I was going for. I just turned the spindle up to its fastest setting and then adjusted the feed rate and depth of cut. I would set them pretty high but back off a bit if there was chatter.
And I'm no CNC expert so if someone knows how to correctly figure out what feed rate, depth of cut, and spindle speed should be used, you could leave a suggestion for Pandonaut
@@CarbonCoil ah alright, just wasn't too sure how I'd know the speed since Im still using the stock spindle and people have actual numerical values
Hi. your engine is also very hot?
don't be a bad liver
Can I buy that 3d printed mount somewhere ? Don't have one :(
I believe so, although I'm not sure where. You can also buy a whole metal spindle carriage for the larger motor www.amazon.com/dp/B08SC9K538/
@@CarbonCoil Thanks dude!
Is the 3018 sturdy enough for such a high power spindle?
It's sturdy enough that I've been using it ever since the upgrade with no issues. There is a little vertical play that is made worse because the new mount sticks out further, but I don't usually notice it unless I'm milling something that needs a lot of precision (like facing the top of aluminum).
@@CarbonCoil Thank you for your reply. So. Aluminum isn't really possible with this upgrade?
@@nabbl2006 I'm actually working on a video about this topic at the moment! Milling aluminum is possible with this upgrade, however, the surface finish just isn't the best.
@@CarbonCoil ah cool. Waiting for it patiently 😁
It's finally finished! th-cam.com/video/kODvQ1fMYXU/w-d-xo.html
Is there any way to still control the speed with software?
In my current configuration I can't control the spindle speed through the software. I do it manually at the start of the cnc job with the potentiometer connected to the motor controller. However, the software can control the movement speed (Feed Rate).
@@CarbonCoil how do u figure out RPM with potentiometer
@@Pandonaut To accurately measure RPM, you need a tachometer or stroboscope. However, I have heard these 500W spindle motors spin up to 12,000 RPM at max speed.
Tools required: zipties, 3d printer, and ... a hammer?
Correct, excluding the tools that come with the CNC of course (such as allen keys to take apart the spindle carriage). Additionally, hardware such as a power cable and some M4 bolts/nuts are required. Someone in another comment also mentioned that a rubber mallet would be better instead of a hammer, but it isn't strictly necessary.
What's your setting for candle with this new motor?
The motor isn't hooked up to cnc electrically. I just control it with a potentiometer.
@@CarbonCoil thank you for you answer. And feed? How did you set it?
@@chazy10 I use a free online software called Easel (instead of candle). Based on the material selected and the size of the bit, it recommends feeds and speeds to use. I just follow those. (New video coming out soon covering this topic!)
@chazzy10 Here's the new video explaining it! th-cam.com/video/NNnxV0NLdXE/w-d-xo.html
imp 3d pla or pbc? thanks bro!!
I don't exactly understand your question, but the new mount was printed using PLA filament. (I probably should have made it from some other better material but that is what I had on hand)
@@CarbonCoil I did print a PETG version since it may withstand higher temperatures and mechanical stress
What speed settings should I use in easel
I just use the default settings on easel, however with the 500W spindle you can speed up the feed rate quite a bit before you start getting chatter.
Here's my new video explaining all the basics of using a 3018 CNC! It explains how to set feeds and speeds. th-cam.com/video/NNnxV0NLdXE/w-d-xo.html
Looking to buy or make an American Made CNC. Any suggestions?
If I was to build another CNC, I would most likely chose the LowRider from V1 Engineering. Its a mostly 3D printed Cnc and you can either print the parts yourself and assemble it using a hardware kit from their website, or alternatively just buy the kit with the 3d printed parts included. Either way its a cheap option if you're ok with some diy assembly.

@@CarbonCoil I have a 3d printer I built from 3d printed parts. That seems like a good choice for me.
@@wartlme Sounds good, I'd love to hear how it turns out!
@@CarbonCoil Aww gee doc, that 3018 is so neat and compact and has lots of potential with a few mods to really perform, whereas the low Rider model is starting to look like a biggo where does it go model.......point is, where do you stop enlarging it before you need a room just for it.
That would be OK for those that want to start making ornately carved front doors or table tops etc on the cheap.
I'm considering making a 3018, not with aluminium profiles bolted together as that is a production model especially aimed at the home builder DIY market, but in a steel tube all welded frame the same size as the 3018, mainly because I like making things but also with more potential for milling aluminium and maybe brass etc.....that would definitely need a stiffer frame and after viewing a few videos and reviews on the 3018 the bug is starting to bite.
Dear Sir., I'd like to revamp my 3018.
Can you give me the 3D output (Mountain Bracket) data?
The link to the 3D file for the mounting bracket is in the description of the video: www.thingiverse.com/thing:2719169
@@CarbonCoil Thanks for sharing the material.
Couldn't you upgrade to a dremel instead? I'm asking as I'm looking to get this machine and upgrade to a dremel instead
Yeah, you could. I haven't looked around for a video that upgrades it to a Dremel. The biggest problem I think would be mounting it.
Please give me a link to the model for printing on 3D?
www.thingiverse.com/thing:2719169
@@CarbonCoil Thank you, I downloaded and printed this model, but my machine has a center distance of 38 mm. in this model 38.8 mm this is not suitable for my machine
Dude, post longer videos
Planning on making my next CNC video a bit longer, thanks for the feedback!
We have same spindle 500w,i try to cut aluminium using this spindle,you must try and see my videos
In the future I'm also planning to order some aluminum and try engraving/cutting it with my machine!
@@CarbonCoil yup,good , waiting video upload
to dangerous not starting and stopping the spindle with the program definitetly at least need an Estop , I am saving for a more rigid cnc
Agreed, now that I'm finished my testing, I plug in the spindle from pretty far away after setting the speed and closing up the enclosure I use. Adding an E-stop and/or other safety feature modifications could make for a good video :D
Ti consiglio di inserire anche un piccolo aspiratore.
Good idea, I am currently working on creating a dust removal system.
new spindle can cut faster.then i 3d print this bracket xD.remove al those plastic parts lol
Hello! sorry but how do i connect the kit on the 3018 pro? i can't understand well from the video, is some other component needed?

To physically connect the 500W spindle to the CNC, I 3D printed a mount for the motor. They aren't currently connected electrically, I just use a potentiometer and motor controller to control the speed.
ok so you need a separate potentiometer in addition to the kit? because I wanted to connect it to the machine but I didn't know how to do it
@@gabriele9153 No, a potentiometer comes with the kit for manual control. Usually I just turn the spindle on manually when I'm ready to start a carve. Im not sure how to connect the spindle to the CNC so that the CNC has control over its speed but that might be a future project for me to look into.
ok I understand, can you tell me which power supply you used to connect it to the mains?
You should be using a soft mallet not a hammer
Good point, but it all worked out in the end! :D
Great info but please turn the music off. Makes it hard to listen to what you're saying.
Thanks, will do for the next video!
Cooperation request:
Hi dear sir,could you tell me how to contact you?we want to cooperate with you,look forward to your reply,thank you.
You can contact me at the email address carboncoilbusiness@gmail.com
Also, I'm not sure why your comments keep getting deleted by TH-cam. Apparently it's a problem for some other people too. Hopefully this gets resolved soon
There is a upgrade kit here for the 500W spindle mount www.ebay.co.uk/itm/224165570574
This could be a good option if someone doesn't have a 3d printer. However, this listing doesn't come with a motor controller so that would need to be purchased separately.
@@CarbonCoil True but that is easily and more cheaply bought from china. mount is just to solve a problem. the buyer is already saving money from not having the seller bundle that with it because the seller could easily bundle it all and sell it for much more. instead. just selling the mount so people can be free to CNC.
@@devil2005iscool For sure, thats true
I do not understand why it seems to work well for you. Mine has lots of play as in this video linked here. Does your spindle have the same play ? th-cam.com/video/QOfZ-GKo5Bg/w-d-xo.html
Yes, my spindle has the same play as shown in that video. It's not really a problem when working with lighter materials such as wood
