Nice upgrade. I always learn something. I hadn't thought about how to use the zero on the calipers to find the centers between shafts. Nice upgrade.
Flipping over the "Z" axis was brilliant! I actually watched this video before ordering my 3018, so that was the first thing I did when assembling it. Ordered thrust bearings for all the stepper motors at the same time. This way I was able to do these upgrades as I assembled the unit.
I also have a 24 volt 20,000 RPM spindle motor. Have not installed it yet, but that will be the next upgrade...once I sort out how to actually use the machine properly.
Thanks for these very useful and helpful videos. Really helped me decide to finally get one of these.
At last I took the plunge and your design printed perfectly there are a couple of things I need to work out though but am really happy with the result. I realised that I had not put the bit into the chuck far enough and I was getting quite a bit of resonance. Also when I took the first part off the machine I noticed the outer edge was not straight on the vertical edge. Un-known to me one of the bearings had slid out of the holder so I was getting a tiny amount of diagonal shift. It was so satisfying though seeing these pieces produced. Thanks for your help
Definitely the most effective and elegant upgrade of this stock CNC. Thank you for sharing your solution, Sir.
Thanks
Loved it. Just starting down the CNC rabbit hole and found your video very useful and well done. Love the way you show start to finish, software, hardware everything. Thx.
I just realized this all for a 3018 and I have a 3018 Pro. Everything looks different, sucks getting old and half blind. Thank you for the great work you do.
I have been searching for over a day trying to find out if I can upgrade the motor on these mini cnc machines.... Thank you soooo much my dude
Great video. It must have taken twice as long to produce this upgrade whilst filming everything. It would be interesting to see the Z axis deflection on this machine and ways to improve it. Great work.
Thank you. Awesome video. I learned more in 25 minutes watching you than I have in days of googling.
Thanks for this. My 3018 board broke so changed to a GRBL/Arduino board and didn't realise it had no spindle output onboard. Was just looking at one of these spindles to replace it - but will need to 3D print the holder for it as obviously no CNC at the mo. Will give it a go from your plans.
Great job! That spindle motor holder looks like a piece of art :) Thanks for sharing!
Brilliant I wish I understood half of what you do but I find it so interesting to watch this machine is currently on order so will definitely be referring to your posts. Thankyou
Nice video, the way how you assemble the Z axis, shown me, you know what you are doing, works for small quiet fingers. Good job.
Wow, really cool! I was put off from buying the 3018 because of the weak motor but I can definitely see myself using one with this upgrade.

Great upgrade. I might needed to do this and you have presented very well.
Very impressive work, thank you and for the gcode for the support. Excellent Video and a much better solution that a lot of others I have seen.
Awesome upgrade from an expert. It's the best video I have ever watched. Unfortunately, I have tried upgrading my 3018 with the same 500w spindle and the Original 3018 CNC Router 3 Axis Control Board GRBL controller from Bangood. I followed same procedure you did. After 2 minutes the power supply was damaged. Actually, I don't know the reason. But their was a relay in controller board 12 v and the other 24v relay in between 2 controllers. I think I have to bring a new one. Thanks

Thanks for the great video. I will need to at least make a version your spindle holder to replace the original which is cracked in several places. I also used your assembly video as an instructional video to assemble mine... FYI.. that's how I found your channel. Your video is posted to the sellers web-site. Good work. Gave the sub.
You Mr. just got a new follower. Very neat project.
That's a great video, thanks. Your engineering is sound but the result is a greatly diminished Z axis travel. With the bolt on spindle you can't slide the motor up or down to compensate. I'm working on a 500w upgrade on my new SainSmart 3018 with the aluminum clamp on a 3D printed slide. I just have the broad Strokes worked out. Nothing finalized. Thanks again.
Impressive upgrade, thanks for sharing the details, liked and subbed.
Merci pour cette vidéo. EXTREMEMENT UTILE. BRAVO.
Good idea! I just turn the spindle on by hand via a switch. This is more elegant.
It is very helpful in making a good video homemade cnc. Thank you
You should change your name to McGuyver... Absolutely brilliant. Loving your videos.
Nice, might have to do this with mine, although at that point I might also go ahead and build a new frame too for a larger area and ditch the 3018 altogether lol
Well done, plan to do that this weekend. I changed the NEMA 17 on the Z axis to a dual shaft,
and added a knob to the upper shaft to move the spindle up and down by hand. Makes setting
the Z to zero easy.
Thanks. Good luck with your upgrades.
thank you, exactly what I was looking for!
Love you video; high quality, along with the upgrade. Would an Optocoupler Isolation Board provide the same function as you 24v dc relay? And if so, could you point me to the correct board?
Thanks.
Great video. Detailed and well explained. Thank you very much.
You are welcome!
Enjoyed your video, good project and good video production. Is it necessary to have so much stick-out on your endmill while cutting? Maybe the chatter can be reduced if you choke up on that tool?
Thanks for this, which model 3018 do you recommend?
4:43 Nice trick to measure precisely the distance between axes, too easy!
thorough review/upgrade, nicely done Sir
Thanks
Your work is super! If you secure the base, you can cut aluminum
First I wrote and then in the video you did it)))
Thanks
Epic man! really cool job!
Great job...made for very enjoyable viewing. Bit touch and go when I saw the ridiculous hand condoms but you were soon rid of them :D
Does the weight of the new upgrade effect the CNC in anyway? Not sure how much the motor weights but i was wondering the whole time if it put extra strain on the metal rods holding the spindle.
how does this new mod perform when making pcbs? especially with smd components. thanks in advance.
Nicely done spindle holder. Could you please tell me what size screws did you use for the square flanges. Thanks for sharing.
Great video. I'm very tempted to build your Z-axis upgrade. I'd be wary of that PSU though. It doesn't come close to complying with EU safety regs and isn't CE marked. It really shouldn't be imported.
A beautifully clear video thanks.
Thanks
Wow you probably fixed the crap z axis as well. Well done! I wonder if you could take two of these kits and make it double shear x and z axis.
Hi, Nice video, the quality of the parts looks pretty good considering the cost of the machine. Have you tried any 3D milling with the 3018 machine? I use Mach 3 with a taig CNC and wondered if the Arduino and GRBL board were up to this?
What a great video, thanks for sharing 👏👏👏👍
You have the Same 100% ideology as myself. I Like IT.
hi, can you please tell us what kind of software do you use for preparing sketches and generating gcode ?
Добрый день.прекрасное видео.Спасибо за ссылки на детали и проект.Скажите пожалуйста какую вы используете фрезу?
Great tutorial, thanks so much 👍😊
well done much food for thought
Great video, Thanks for the great video!
After changing the old spindle to a new 500 W, what parameters were set for the cutter: engine speed, depth, depth in one pass, feed speed for the cutter 3 mm ?
I'm looking to get myself a CNC router for cutting carbon fiber plates up to 5mm thick for custom drone frames. Would any 3018 model be ok and just do this spindle upgrade or should I be looking at something else?
I've looked at many 3018's and haven't noticed much difference other than the price. Like the SainSmart is $350 but I've seen others as low as $150. Should I stay with a trusted brand or maybe something in the middle. I know I should probably avoid the cheapest option.
Strictly hobbyist use.
Thanx ^_^
good build , check the voltage of the speed pot pins with ref to earth.. just to make sure its safe.
Is it work with Mach 3 controller.Are you using 18 gauge silicone red and white wire for connecting to control board
Great video, what fuse rating did you use in the 3 core UK plug?
Clean, well edited, quality video as usual! Question: why did you put in a longer lead screw? To leave some sticking out of the bottom so you can hand turn it if you want?
Plan A was to have a bearing in the bottom of the holder, it turned out not to be necessary.
@@techydiy Thanks! I'd been wondering the same question. Tidy work, and great video, so thanks for sharing.
Impressed, very nice.
Both ends rotate. Is that just for the fan, or is that a flywheel of some sort? Intentional mass to increase torque. ?
just kinda curious , I am purchasing a 3018 w/ laser engraver also the router and bits turn it in to a small 3 axis inc router ... Way cool ! I am so excited for this it un real .
@techdiy
Any chance you have an svg or similar file for the spindle mounts?
Very good. Thank you!
Nice upgrade. I'd be interested to know if the additional weight of the bigger spindle motor and the additional cantilever distance away from the gantry causes unwanted deflection.
It definitely does. Not much of an upgrade if you ask me, it actually takes away from the functionality of the machine. I'm wishing I hadn't dropped the money on mine
I like it, would like to see the potentiometer replaced with a voltage divider circuit to allow the software to control the spindle motor speed.
Дякую. Цікаве відео. Лайк!
thanks a lot! Great job!
Very nice!!. Clean and easy.
Cheers
Thanks 👍
Hey I have a question and it might seem obvious but how are you getting such good height on the Z you have the base plate then what looks like 15mm - 20 mm mdf then you cut what appears to be 20mm mdf into a ring. Are you pushing this to its height limit and does the 500w change the height? Thanks for your great videos dude they are epic.
Bel lavoro. 😁👍
Thanks for the video but the z axis motor is only rated for .24 kg. lighteset 500w spindle I could find is over 1kg. Is the chatter bad or have you had to upgrade the z axis?
thanks for the arts 🥺
Great video and cool upgrade. Could you use the PWM output to control the 10V input too ? Obviously you'd need a PWM to linear 10V conversion but that shouldn't be that difficult to do.
I would think so.
Well done. 3 weeks ago I received my CNC3018 PLUS, which already has a 500W spindle as standard. And I also ordered the 40W laser at the same time.
But for the other 3018PRO that only have a toy motor as an AS drive, this upgrade is a worthwhile investment, because for proper milling / engraving you need at least 300-500W.
Awesome upgrade! Can you tell me if I can install the same 500w spindle motor in the Sainsmart 3018 PROVer with the same instructions that you used in this video? Cheers
I don't know, the plates might need some modification, you would have to measure the parts and check.
Great video. Could you please tell me what resistor you added to your relay circuit? Would love to keep the on/off function in the software.
The circuit diagram is on my website, link from video description.
What does this upgrade offer? Is it faster or something else? Is the speed at which you can CNC limited by the material you're cutting? Meaning, if you cut too fast the quality will drop. If that's true, have do you find the optimal size motor so that you can cut as fast as possible without going overboard?
Ficou ótimo 👏👏👏
How well does this mill aluminum?
So much great information & ideas in this video. Many thanks.
One question... do you have a link to that surfacing bit? Is it 1/8" shank?
Its a 6mm shank, so you need a 6mm er11 collet.

22mm surfacing bit www.banggood.com/custlink/m3KYEqnoPj
Can you give me the size of the screws and the spacers that you used. so I can order them or find them in a hard ware store.
Very cool! Will this upgrade allow machining harder materials?
You're talking about Alamantium, right ?
Great thanks for sharing.
For wood is it necessary to cool the bit? And at what air pressure?
No need, as long as your feed rate is high enough. Low feed rate is what causes wood to overheat and burn. A dust collector boot helps with the mess
Great video, very useful! Just wondering how noisy is the 500W motor (compared with the stock one, for example)? Cheers!
A fair bit less noisy I would say
Excellent, informative video. Unlike many TH-camrs, you really understand CNC.
Just one question... Is it possible to control spindle speed using PWM from the microcontroller, instead of a potentiometer?
You can but it require a bit more electronics to implement full pwm or you can buy off the shelf pwm to analog 0-10 / 0-5V voltage adapters to allow connection to the power supply.
With this setup is it only possible to turn the spindle on and off or is speed control with the software also possible?
I upgraded the hole cartage with an 4mm aluminum cnc cut plates and replaced the linear bearings with and scs08uu Bearings, I can send you the cartage design to review and try it on your machine
No BS. Just facts video, thanks for making it.
hi! thanks for sharing your upgrade and nice job! I wondered if it was possible to cut thicker aluminium like 6mm or so using this kind of equipment...?
Yes you can
You should include 3d milling demos in your cnc videos
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?
another great video, thanks again,
Thanks
Hello, really nice and thorough review, keep up with the good work :)
Can you tell me what transistor is at Q3 and Q6 inside the power supply?
J6
@@techydiy thank you ! :D
Excellent video... Some very ideas ...Thank you
Great video thank you.
Will this motor work with the Cronos board that is supplied with the 3018 router? (Only the power supply needs to change?)
I believe that you can wire it in the same way as shown in the video
Love the video. Thanks. Just wondering if the 8mm lead on the leadscrew had any effect on the operation, as it is usually around 4mm per turn.
brilliantly condepted upgrade for the little 3018. Did this improve the operational noise of this little machine?
It is a bit quieter
Thanks for an awesome build. Did you have any problems with the Z axis step distance when you completed the upgrade? I have just completed this exact upgrade but have found the z axis now moves approx 30mm for every 10mm command in easel. Did you come across this?
Configure the z axis steps per mm setting for the new lead screw.
The following video explains it (different machine same process)
th-cam.com/video/u4Mcjz7IP10/w-d-xo.html
Excellent thanks.
Excellent video! Thank you so much for sharing your creative re-design of the z-axis. Can you please provide a link to the where to order the 2 flute 3mm endmill from. I have been contemplating to get one of these 3018 sized low cost desktop CNC for learning. But I have resisted it because of the very small workarea of the Y-axis. I am looking to mill Acrylic/wood/thin aluminium very similar to what you showed in your video but I woud like to have a workarea of at least 300 x 300mm. This model only does 300 x 180mm. So I was thinking of say replacing the original side rails, thread screw & guide rods (Y-axis) with new ones measuring about 500mm. Your thoughts on this mod will be greatly appreciated!
The bit was in this set bit.ly/3gcrdKN
You can expand the machine, but to make it stiff enough you will probably have to replace most of the rails.
In the video after next (early september release) I am testing a cnc with a 300mm x 400mm work area.
@@techydiy Thanks for your reply and I will look forward to seeing your next video!
Like your work. I wasn't 100% onboard with your material choice for the new mount, But it looks robust enough and I didn't make out any chattering vibration while it was cutting the aluminium, So it's probably just an old mans "Metal is best" prejudice rearing it's head again. :)
I keep thinking about getting one of these little CNC router/milling machines. Trouble is that I trained as an engineer on bleeding great aerospace milling machines that could rip 200 thou cut's off blocks of alloy at ridicules feed speeds while using 2" cutters. After that, even something like the ever popular Bridgeport series 1 felt like an under powered and slow toy.
I think that using a desktop CNC machine would just frustrate the hell out of me, and make me wish I still had access to "Proper" sized vertical mills. :(
It is a great toy to start with.
