Cnc 3018 Upgrade with a 500 W Spindle Motor

[@brucewilliams6292]

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.

[@joetke]

Definitely the most effective and elegant upgrade of this stock CNC. Thank you for sharing your solution, Sir.

[@techydiy]

Thanks

[@NJP76]

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.

[@bigcountryvet5984]

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.

[@DIAC_Electronic]

Nice to see someone else prototyping with acrylic sheet - so much easier than steel / alu

[@shaynekielmann-kn2tx]

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 .

[@paulwills7902]

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

[@999fugazi]

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.

[@johnhill2594]

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.

[@techydiy]

Thanks. Good luck with your upgrades.

[@WiggyB]

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.

[@SuperCozMick]

Thank you. Awesome video. I learned more in 25 minutes watching you than I have in days of googling.

[@tjones99]

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.

[@PortalFPV]

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 ^_^

[@perceptronimaging7558]

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?

[@brucenorton3864]

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?)

[@techydiy]

I believe that you can wire it in the same way as shown in the video

[@chrisryan3445]

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.

[@tomjoad6993]

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?

[@MrMartinoef]

Just getting sorted to do the upgrade now! I'm not electronics minded & notice there's a diode? on the circuit board. All I think I know is a diode lets electrons? travel in one direction through the circuit but, I don't see a reference in parts list - anyone know if there's only one type of diode or are they rated like different resistors etc. May be stupid question but there isn't a stupid question if you don't know! Thanks in advance.

You're talking about Alamantium, right ?

[@othoapproto9603]

Hi, is there a term for building a machine that then you can use to make better parts to improve that original machine? Is there a developed system of strategically improving certain parts to improve the original machine's accuracy? If I 3d print parts to build a CNC router, I would want to use it to cut aluminum parts to replace the 3d printed plastic parts. I don't think machining the precision parts like gears, screws, sliding surfaces with the original machine would improve the machine.

[@faniyat565]

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

[@brain3845]

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.

[@Pnky-chan]

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

[@tazanteflight8670]

Both ends rotate. Is that just for the fan, or is that a flywheel of some sort? Intentional mass to increase torque. ?

[@garrigarikov4541]

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 ?

[@neco777777]

Great job! That spindle motor holder looks like a piece of art :) Thanks for sharing!

[@phillipcoolman1193]

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?

[@techydiy]

Configure the z axis steps per mm setting for the new lead screw. The following video explains it (different machine same process) kzbin.info/www/bejne/q2WwlJ2wbK6DZ5I

[@UberAlphaSirus]

Your gonna need to earth the spindle and frame. That 100v looks to be mains referenced. It's DC too so if you grab something live, you won't be able to let go.

[@techydiy]

Yes you are correct, It is mains referenced and the spindle should be earthed. The mounting threads at the bottom of the spindle are quite an easy place to attach the earth..

[@wernerviehhauser94]

This is incorrect, the let-go-threshold of DC is much higher than AC (see this study www.wright.edu/~guy.vandegrift/wikifiles/Electric%20Shock%20Hazard%20Dalziel.pdf or consult the IEEE or wikipedia pages on electric shock). These myths date back to the Current War between Edison and Tesla. Nerves work with alternating voltages, so AC affects them more than DC does (short DC pulses in the ms range work like AC). But this does not make DC safer, it's only dangerous in different ways. Nonetheless, the spindle should be connected to PE or sufficiently insulated as 100V DC is anything but a safe voltage level. Edit: fixed html link

[@nixmamd]

Also, the output is nearly 300v with 30% max duty cycle pwm (230v version at least). The big capacitor also stays charged for a couple of days. And it is main referenced. I also use an optocoupled pwm for speed control. The inputs are a bit weird however, as the voltage difference between the outer two changes with spindle speed. I'm still searching for a decent power supply to replace this one.

[@Paul_VK3HN]

@@nixmamd Let me know if you find one. I am not wild about rectified mains, no isolation.

[@hubschenk1652]

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.

[@pantv841]

Great video, what fuse rating did you use in the 3 core UK plug?

[@tjh44961]

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.

[@zrpickups5729]

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

[@beykana]

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?

[@woodworking3815]

Are you aware that the spindle power supply output is not isolated from the mains voltage? I recommend adding a PE/Ground connection to the 3018CNC frame.

[@techydiy]

Yes, your right it's mains referenced. For anyone else reading I added an earth to the bottom of the spindle (m4 screw) and the power supply is now in an earthed case. Earthing the spindle created problems with the height probe, so I also added an opto isolator between the probe and the grbl control board. Battery power supply for the probe side. There is a bit of detail here: kzbin.info/www/bejne/l5-Te4eEn8-grcU

[@JamesThompson-xl4yu]

Why didn't you make a new spring for the horizontal bushing like you did for the vertical ? All in all do you recommend this cnc for a starter?

It is not as necessary

It worked but it really depends on your own setup

[@leec2106]

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.

[@bafa_tents_services]

Great thanks for sharing. For wood is it necessary to cool the bit? And at what air pressure?

[@greensheen8759]

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

[@warrenking1815]

Really nice video, great job. Why did you use acrlic? Would abs work better?

[@techydiy]

Optical clarity

[@Reman1975]

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. :(

[@pj8979]

It is a great toy to start with.

[@mrbiggs110]

Thanks for the video bro I wonder if a 3d printed part would be just as good for the motor upgrade?

[@danielmcarthur9004]

How come you chose this motor? Why not a GS-775MR motor? Higher rpm and fits without modification. Just wondering.

[@techydiy]

It's another option, although I don't recall seeing them around at the time.

[@69LINX]

Good morning, congratulations on the video. I have a question for you: is it possible to connect the wires directly from the spindle output of the cnc motherboard? Else, what is the value of the resistance on the pcb?

[@techydiy]

Can you drive the new spindle motor directly from the PCB ? No

[@frodobaggins169]

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.

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.

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.

Can i still use the original laser add-on with the 500 Watt kit added on or is there something stronger faster better I should get?

Thank you very much for the video. I would like to make the same. I was wondering (after some research) if instead of the PCB with relay+diode, a Solid State Relay (no need for a PBC, no need for a diode?) would not simply be OK for the job: I was thinking of such one like SSR-10DA DC-AC Solid State Relais-Modul DC 3-32V zu 24-380V AC Spannungswandler ? Or is a SSR-25DA also OK or even better? There are some for few euros. Is it a valid option at all? Thank in advance.

[@techydiy]

Your only switching a low voltage so it depends on the spec of the SSR. You can of course use the SSR to switch the mains input. Another alternative is an opto coupled relay board, in this case you would switch the low level switched input.

[@patheron7812]

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?

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.

It's probably a faulty 24v power supply or the power supply overloading. The crimp connections on the motor wires are sometime poor, check those. Failing that its either the spindle motor, motor cable or the pcb.

Thanks.

Good idea! I just turn the spindle on by hand via a switch. This is more elegant.

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.

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.

[@techydiy]

I would think so.

This spindle is very weak. It fell apart after a few days. In total, it worked for several hours. The carbon brush holder cracked, the brushes jumped out of the holder and shorted out. As a result, the GRBL controller was damaged. Bakelite handle 1.5 mm.

That’s not normal, send it back.

How well does this mill aluminum?

Very nice video! The link to g-code don't work. Would very much appreciate it to avoid reinventing the wheel.

@@techydiy Hi! The reason was that KZbin went down completely yesterday. I've managed to download now. Thanks. I've ordered parts for your upgrade. Can't wait to get started. BTW Your video Is one of the best on this topic on KZbin ( and I think I seen the most!)

[@anthonydrake7767]

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?

[@techydiy]

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.

[@paulriley5940]

Maybe i missed it is that extruded or cast acrylic?

[@techydiy]

Cast

[@ЮрийСтоянов-ф5л]

Добрый день.прекрасное видео.Спасибо за ссылки на детали и проект.Скажите пожалуйста какую вы используете фрезу?

[@Q5Grafx]

if you run a pair of wires from the variable 5v contacts on the board to negative and var on the power supply and no relay is needed and you get full range controller controlled speeds

[@techydiy]

Yes that output is available on some mach3 controller boards or are you talking about the 5v pwm output?
