Thanks for the prompt reply, Motor does work, I have just ordered a new controller board that can handle up to 10A, so I will connect the motor to that to see if that cures the problem. I will keep you posted.
Hey just wanted to say that I really enjoy your videos as you go into detail with your explanations which helps so much as you answer the questions that I haven't thought of.
Thank you very much 👍
Thanks James. I'll give it a go at the weekend and see how I get on.
Hey James. Great video as always! Good job. Could you do one on cutting, engraving bits? That would be amazing. Ta
That would be good!
Yeah, I agree with this suggestion. A lot of makers are not up to spiff with different bits and their capabilities and weaknesses.
Appreciate your videos, I have learned alot from them. I have only been doing CNC for about 2 months now, You are the best on the 3018 cnc with your info. Most of the videos I have found are for the larger machines. I am really interested in just how far I can push the speeds on mine with the stock spindle.
Thank you 👍 just start slow and build up. You soon start to tell because you getting more chatter which is a clear indication you're going too fast
Hello James thanks again for the videos. I wrote to you recently about the Sainsmart 20k motor being
too noisy. I asked some other users and some were noisy some quieter. Sainsmart sent me another
one and it is fantastic. The first 20k recorded 85 to 90 decibels half speed no load. The new one is
75 max top speed. Thanks for your suggestions, am now looking forward to some nice jobs.
Regards Keith
Mine is deafening and when i asked SainSmart about they said it was fine. I feel like they just didn't want to send me a replacement
Hello again James: I enjoyed this video and learned something about swapping the stock motor. My Sainsmart 3018 PROVer hasn't yet arrived so I have no feel if the stock motor will be perfectly OK for my needs (PCB etching). I suspect the stock motor will work but having the higher RPM produces cleaner cuts, so it's something I may consider. However, I noticed your machine in enclosed in a case with door, and has an extraction fan as you mentioned. It would be useful if you could provide commentary (perhaps in a separate video on the topic) on how your setup handles the lose particles as they're removed from the work; where do they go, what kind of extraction pump, etc. Another video that would be great to see for newbies (such as myself) is reviewing the various kinds of BITS and what they're used for and what not to use for a particular kind of job/work. Looking forward to more of your videos!
Careful with the 'Speedster' upgrade James Dean 😉
Great video, thanks. I am getting a little confused with what spindles you have fitted. Can you tell me please? Have you tried upgrading to a 300W or 500W spindle?
Thanks again for another great video. I purchased that spindle and a power supply, my power supply has a tiny voltage potmeter. can you post a video of how build a speed control with a small volume knob or something similar?
Hi James, like many I am new to the CNC game and I have learned a lot from your vids. On the power side of things, have you thought of using a powered usb hub? I use a powered switched usb hub attached to the top of my case (based on your build of course), and I have a switch for my usb led light strip, intake fan and exhaust fan. The benefit is I can run what I want, when I want without it going through the same psu as the board and spindle. What do you think?
Hiya James.
Awesome job with the videos. Really getting the benefit.
You weren’t wrong with the upgrade. Just fried my power brick.
So going to get a new one.
Did you connect from the PSU to the 3018 and the motor from the control board?
Yes, the psu connects to the board and the board powers the spindle. You can power the spindle directly from the PSU but you would need a 24v dial to control the speed, and also a solid state relay if you want the board to turn it on and off so it gets a little more complex
If you prefer to stop start a higher voltage motor using the controller. This can easily be done by adding a small 12/24v relay. But the speed control would need to be done manually by using its own variable speed controller.
James you can auto start the spindle using a relay that is triggered by the spindle drive from the control board.
The only drawback of having an external power supply is that it is not possible to control the rpm from the software any more.
@@stanislavtodorov8705, you can use a board like this to use a different power supply but maintain the mains board control the rpm:

@@paulocabrita2055 how would you need to wire it then?
Hi James, thanks for the videos. I am new to CNC and your videos has really helped me learn how to use my 3018 pro. I am looking to do this upgrade, currently I’m following your advice with the stock 10,000 rpm spindle and doing speeds of 450mm/min for plywood. Would be great to know what the increase in speed is and what you would recommend for a max speed with the new 20,000 rpm spindle! Always worrying about going too quick and breaking bits. Keep up the good work!
Hi Issac. I've not pushed it to much at the minute but I've got upto 800mm at the minute at about 0.7mm per pass on MDF. So it's certainly bringing the cutting time down.
Hi James,
What website can I access to add tools to my toolbox? Easel seems to be very limited even with Pro
You can put a relay on the control board to turn on the motor power supply
Hi James,
One of the stepper Motors on my 3018 pro max has developed a problem and I'll need to replace it. The original part is a Cronos 42BYGH34H-2A-13D. Can one replace this with a generic stepper motor and what must I watch out for?
Good Morning! As for the amps drawn and the max amps that can go through the control board: I've encountered a similar situation with one of my 3D printers, which is just so so and suffers from occasional crashes if too much power is drawn from either heat bed, nozzle or motors. I've put in a solid state relay which is PWM friendly connecting the power from the PSU directly to the bed (the motor). The PWM out from the control board connects to the SSR control input. So if you experience trouble with the spindle together with the control board, you may consider this option.
Thanks Michael. That good to know. Its why I love TH-cam, lots of knowledgeable people :)
Hi, a possible solution to not fry the control board would be to use relays for the spindle lights and whatever else except the step motors
James , thank you for these video's. I have recently purchased a 3018 Pro and found your vids to be the most easy to understand. Being a retired ludite would it be possible to show a wiring diagram for the psu? Many thanks. Denis
Hi Denis, its probably not worth making an entire video for it but if you message me on Instagram or Facebook I'll send you a quick video over of how I did mine
Fitted that spindle in my case it was a lot noiser James.
Hi I'm having occasional issues with the spindle not lifting when moving from one part of the carving to another and it leaves an unwanted tool path any solution for this or is it an issue with easel software
Any update on this motor I ordered one but after ordering it I found a 500w motor on banggood. So I would love to see how this motor works for you. Thanks as always
Were can you buy the cutting bit , I just bought one , and like bits for it. Like your videos very helpful. Thank you ,for letting me know about the bits
I get all my bits from Amazon to be honest. The blue tipped ones from Sainsmart are pretty good.
added a new 20000 motor and the ungraded PSU works brilliant. thank you for the video, any chance of doing a cast acrylic engrave and cutting tutorial?
Hoping to do one soon :)
Thank you for the doing this upgrade video. I have upgraded my 3018 Pro with a new spindle from SainSmart. They said it was compatible with the 3018 Pro. I say not as the controller and power supply cannot handle it. I don't think I can run the kind of current through the Woodpecker controller that is needed. I am working with SainSmart now to see what the best solution would be. I recently published an upgrade video for the new spindle motor. Seems I will need a second one as well. ;-)
You're not the first person to mention this about Sainsmart. I usually give them credit but I also found it strange they only released this spindle in the US - the sceptic in me thinks it was because they didn't want to go global if they knew there might be some problems
@@JamesDeanDesigns I have had good luck working directly with them. I even got a new laser kit from them and I did an assembly video for them.
My suggestion: Those controller boards are not very rugged, and heat is the enemy of all electronics. I suggest an inexpensive relay that runs off of the controller, but then drives the spindle directly from the PSU. That way the spindle still turns on or off automatically (via the controller), but the load on the controller is even less. [There is almost certainly a reverse diode on the board to prevent back EMF from the spindle (now relay), but check just in case.]
I would like to suggest doing a tutorial of the final assembly. Thank you.
Hi, what do you mean by the final assembly? As in fitting the spindle or the final assembly of the machine?
I'm interested in the electrical wiring between the power supply and the control unit
The vibration on my machine had me wondering where the resonances are and if there are speeds (assuming a motor isn't perfectly balanced) to avoid.
I have a HND in electronics (from 1965 !) so I do understand what you are talking about here, but may I compliment you on a very clear and concise explanation of what is involved in upgrading the spindle on a 3018. You answered all the questions that were concerning me after watching your live video on the subject, and I will probably buy the same motor and the power supply which I was already considering.
I follow your reasoning about not overloading the control board with the extra spindle current, and connecting the spindle separately, but does this mean that the speed is no longer controlled by the control board/software? My initial thought was to include a relay or something similar, energised by the existing connection for the spindle, to remotely switch the external supply to the spindle directly. However, this would not appear to permit speed control, so would not be a simply 'press start to begin' situation (which I would like!). Your thoughts on this aspect would be appreciated.
Thank you. Sometimes it just does feeling like I am rambling, it often makes sense in my head but Im never sure how it sounds to others. In regards to wiring the spindle separate, I think some have the speed control on the spindle its self, not specifically referencing a RPM but usually something like a dial with 1-8 on it. For the ones that do not have this control, Im guessing there is a way to relay the power control from the board to control the separate supply in tandem, or I think people fit some sort of rheostat to control it but not 100% sure.
@@JamesDeanDesigns Like @Don, my first thought was a relay to switch the external power supply. As you say, this doesn't allow the software to control the speed. But, how often do you use anything other than full speed? I know I haven't had cause to but I am running a stock 10000rpm motor.
Hello James,
Thanks for your videos they have really helped.
I have a 3018 pro, the original motor was terrible
And unbalanced so bought the sainsmart 20000k
one, but the noise from it at any speed or bit and
even when idling is so piercing I have to ware
ear defenders. I have contacted Sainsmart and
they say this is normal but I have not heard other
videos with this problem. Do you have the same.
Keith
I've heard different opinions. Mine is quiet but others have said there's is loud. What I would suggest is perhaps head to the Sainsmart user group on Facebook and ask if people can take decibel readings. You can download an app on your phone to check. That will give you an idea if yours is within the acceptable range
Hi James, Drawing 10A at 240V is 2400W which is pretty high but a 13A fuse is common in the UK. When you get up to drawing this kind of current it is best to check your household circuit breakers to see if they can handle it. In Australia for example we have 240V and 10A GPOs (General Purpose Outlets) so pulling 10A is really borderline.
These stock motors do not draw no more than 2-4A so a 10A power supply is more than adequate .
James, I am thinking of purchasing the 775M spindle motor but I would prefer to control the motor rpm with a separate manual controller and an upgraded power power supply, could you offer your thoughts on what type controller, also if the controller is not possible then please indicate how to bring up the $ bit (GRBL) and how to set various rpms. Thanks
You basically just need something like a 10amp PWM controller. Available on Amazon for under £10. There is a way to connect it up so the control board turns the spindle on but you then manually change the power - however I've never done this so I cant advise on how to actually do the wiring
Hi James, Sorry this is an old video but wondered if you could advise. I've just ordered the 20,000 rpm 775 spindle from Amazon. I intend to run it on my 4040-Pro. Would you by chance know if I upgrade the stock Power Supply, would my control board can handle the start up current of the spindle. I know the 3018 may be borderline but how about the 4040-Pro. Thank you.
I'm not 100% sure but given the 4040 Pro technically has a more powerful spindle already I would think it has a bit of extra power to run it
Hi James, Terrific site, very helpful. Question:- I have bought a Genmitsu 775 24v spindle and the upgrade PSU that you suggested (24v,15A), problem is when I turn on the PSU the spindle twitches and then again when I turn it off again. Any ideas please? Motor is directly connected to the PSU output.
That sounds odd. Have you been able to check the spindle actually works or even that the PSU actually works correctly? Sounds obvious but just safer to rule that out first. If you have something like a multimeter/circuit tester that can help diagnose where the issue is
@@JamesDeanDesigns the motor now works a treat through the new more powerful controller. Thanks all your videos.
Keepmupmythe good work.
Hi James great videos. The 20k 775 spindle that you shared the link to is not currently available from Amazon and may never be is there an alternative source or compatible motor?
Thats a shame, hopefully they might restock. Try the Sainsmart site as they do a 20k spindle or ill find a link for you
@@JamesDeanDesigns thanks for your help.
Just got my 3018 pro. Noticed max spindle speed in dolla dolla is at 1000. So I need to change that to 8000 for my rpm I want to use or is that 1000, meaning 100 percent ty
hi james great videos for us newbys i have just got started but cannot get the spindle to start when i press go in UGS ?? the machine connects and moves to home etc and goes through the program but alas no spindle. the machine is a 3018 pro mitsui . im sure you have a video with a bit in about this but cannot find it . any help would be good regards keith ps keep em coming bud

Wich mashine is am beste for 20k rpm, which componente ? ( no to much kost )
Hi, James
I have a Banggood 3018 CNC that I have been running off of a 12 Volt power Supply from my Laser, Because the 24Volt will not run the Spinle Just starrts and stops. But when I hock up the 12 Volt Power Supply it runs good but I don't think I am getting the RPM out of it. Do you have any Ideas about it.
Hi, basically they are designed to run at 24v so if you're only using 12v its half the power so roughly about half the RPM.
Hi when designing a project in Easel with the project in the left hand corner does it make any difference if the actual piece of wood on the machine is placed in a different area on the machine bed
No, as long as you set your Zero to the corner of your material
IT would be helpful if you could make a video showing installation of limit switches and an emergency stop button on 3018 PRO machine Thankyou
I've just ordered my Genmitsu 775M motor, arrives early Jan, ouwrt supply next week. Tempted to run spindle manually on separate pwm switch as Easel can't do stepped speed changes! Did you try yours that mode? Do you use Easel?
Hi John. Easel doesn't do it automatically but you can export the code and then just drop in the extra code for ramping the speed up. Mine seems to be ok with the cronosmaker board. I havent needed to to ramp up speeds or control the pwm separately
Thank you James, have a good Christmas with family/care bubble, stay safe, see you next week/year
Looking to do this myself after testing yesterday.
Could you not wire the motor separately then use a relay from the original board connection to switch it on?
Bolting linear rails onto the back of my spindle mount ATM.
There are multiple ways to approach wiring this up, that is one option and you use an SSR relay to turn the spindle on. Hope the linear rail upgrade goes well :)
Hi James
Thanks for all the video help for my 3018 Pro M. I have so far ruined 2 new upgrade 775 motors I have purchased trying to connect the ER11 extension. I have tried heating the ER11 and that didn’t work. Also tried cooling the motor and heating the ER11 but still no joy.
Have you, or any of your followers, got any advise for a novice CNC’er?
Hi Richard, to be honest. I have never had to heat or cool any of mine. They have just been a snug fit and then I pinch the little grub screw up. Have you tried buying a different ER11 collet to see if they fit any better?
Hi James
I will try a different er11. Thanks for your advise.
@@richardtester3985 sorry I couldn't help much more but to be honest if heating and cooling wasnt working, then I'm not sure what wouldas those are quite aggressive methods anyway.
You need quite a strong heat source, gas blow lamp , propane or similar Need 300°c or higher then quickly press the motor to the spindle but leave a gap to motor casing. (Though Genmitsu promise send 765M with ER11 already attached now!)
Hi James,
One of the cronos 42BYGH34H-2A-13D stepper motors on my 3018 Pro max mini cnc has packed up. Could you advise an equivalent if I cannot find a Cronos? Will the replacement be "plug and play" (compatible with the current circuit board and software?)
Hi Bruce, the standard motors called Nema 17. Yours appears to be a 2a version. If you google Nema 17 2a you will get a suitable replacement. I am just trying to find a specific one though, I'll come back asap
@@JamesDeanDesigns Hi James,
You're a star. I really appreciate your help here. Didn't you have the same problem? is an upgrade worth considering?
with the 500w motor you can run the spindle lead into a relay to trip the relay for the power/speed control to the power supply for the 500w spindle and still have software speed control but not use those amps from the main board
Thats good to know. Thank you
yep but beware - there seem to be different types of 500W spindles out there: some with a potentiometer attached to the PSU - and only the potentiometer - and some with an extra control board that can have either PWM input or a potentiometer attached. I think it would be nice if you can control rpms, spindle start/stop and spindle direction forward + reverse all from the software, as one can do with grbl and the woodpecker board and the feeble stock spindle :-)
@@MacBaerFFM but on the power supply there is a small loopback wire. That is where the relay goes. It basically enables the power switch on the back of the power supply. So one side of the relay has only two wires from the old spindle as a trigger. The other side will have a 24v set and one wire going to each lug of the loopback.
@Q5Grafx Er, no, to your original comment about the relay. A relay can only turn the power on and off. If you use that method to control the power, you will lose software control of the speed because you will no longer have the motor connected to the 3018 control board.
The 3018 board outputs a variable voltage to vary the motor speed, that does not get passed through the relay. However, most of those power supplies have, as Michael Grom mentioned, a potentiometer to control the speed. Actually, that is normally just a way to provide a control voltage to vary the output of the new (higher current) power supply and can be used to control speed by using the spindle voltage from the 3018 board indirectly.
@@Q5Grafx Not quite. You'd have two wires from the spindle connection on the 3018 board connected to the relay coil. That will simply turn it on and off - and only if the software sets the spindle speed high enough so there's enough voltage to energise the relay. You then have two wires from the relay contacts to turn the power supply on and off, connected in place of the loopback wire. There is no third set of wires from the relay. The power supply main output is connected directly to the new spindle motor.
If all you're running is the spindle with no lights, fans etc do you still need to upgrade the power supply or should you be ok?
If you don't want to get a new PSU you can either use some code to ramp up the spindle but you have to do this on every job or you can but a little limiter that stops the amps spiking. Its only when the spindle first fires up thats the issue
Hello James.
I am new with cnc mashine. Had same 3018 pro and wanna ask you - what kind of software do you use to make a project. I try finding some to move motors to left/right. Spindel deepness. Can you please give me a help?
Thanks

This will probably answer all your questions on software th-cam.com/video/EMI97Rcb0bQ/w-d-xo.html
Hi again, just received the 20k spindle although im struggling to remove the chuck and collet off the old spindle to put on the new spindle. I have loosened the grub screws although its really stuck on there. Any tips?
This is quite common. The easiest way is to take the nut and collet insert off, clamp it upside down by the ER11 collet and tap the bar out through the middle with something like a screw driver. You can use some penetrative oil like Plus Gas or GT85.
The ER11 is heat interference fit, propane torch 400°c or higher to expand it enough. Unless you have to old style that just secured with grub screw. Heat blueing is tell tale on type identity
Hi James. I have a standard 3018 Pro straight out of the box and am considering the spindle and power pack upgrade. I am a plug and play guy and no nothing about electrics apart from wiring a plug. I notice the power pack has a bank of connections. Can you explain where you wire what. Thanks.
Its simpler than it looks. The connections are just positive and negative, there is space one side for the input power and then some spaces for the output. All I did was literally cut the wires either side of my black brick, threw the brick away and used the wires on the new PSU.
@@JamesDeanDesigns Do I understand this right - you've connected the new 24v power supply to directly power the controller board (motherboard) and your entire system therefore seamlessly switched from 12v to 24v? It would be brilliant if it were that simple... - thanks in advance!
@@pankajkhanna1346 the old PSU was 24v but only 5amp, the new one is also 24v but 15amp. Same volts just higher amps
Hi James,
Can you use this upgraded spindle with the standard PC board that the 3018 pro max was supplied with?
Is there a specific reference for the upgraded 775 spindle you ordered on Amazon? I want to upgrade as well.
There doesn't appear to be any specific references unfortunately 😕 it runs with my board which is the Cronos Maker but different machines have boards as standard. Its a case of just buying and testing unfortunately
Hello!
I would like to ask that with this 20000 RPM spindle, can I work faster? Is it decrease the working time? Will cut the wood like the butter?
This recommended spindle is in a very good price, and I like it. I could replace easily because in the same size like the original. But why so many people upgrade their machine not with this, instead use that black one 300-500 w maybe you know that. What is the different?
So this will help you cut a bit faster, let's say about 20% faster because although it has higher RPM the torque doesn't really increase. Whereas something like a 300w spindle has more torque which allows you you cut even faster. So in short, a 300w spindle is going to be better however it also costs more to make that upgrade
Just bought the upgrades . (Thanks James)After a couple of months of use it seems like a good idea. But one problem I have is when I look at my $$ settings there is no $30 settings. Do you have any idea what im missing?
It might means that, like mine, your control board is grbl 0.9. $I should show you the build information including the grbl version. I know that on my machine maximum RPM is reached well before S1000. I need to do a few more experiments to determine the exact cut-off point but I suspect it will turn out to be 255 as that's the resolution of the Arduino's PWM controller.
You just need to update the firmware on your control board from 0.9 to 1.1. Its quite easy to do, I dont have a video of it but there are quite a few available
@@JamesDeanDesigns Thanks James😊
Hi, the links lead to a currently unavailable spindle on the Amazon page. I’m just curious but what has been the cost of the replacement spindles? I think you said you have had to buy 5 replacements.
The spindles must be out of stock. I ended up sending some back, I think I bought three in total and they ranged between £12 and £20, £20 being for the 20,000 RPM spindle
@@JamesDeanDesigns 👍
Hi james! sorry but by chance you have the link for the er11 reduction compatible with this spindle, unfortunately I ordered one that does not work. thank you
Hi, is it just the collet insert your after? if so it will be something like this that you need amzn.to/2YguOSf
If you need the ER11 collet as well it often works better to buy a combo pack like this with all the inserts amzn.to/3iYSTow
ok I tried to buy that tkanks, instead for the electricity consumption did you do some tests?
Do you have parts list in USA? I have ordered one of those motors of Amazon and it runs fast in slow and slow in fast position. I really enjoy your videos. Love that name, I thought he came back.
Hi, I could get you the links for anything but it would be a guess as to whether the supplier is any good. I generally don't like posting links to products I havent specifically tested my self. Thats odd about the motor. Fast and slow is simply the amount of power being sent to the motor, so the more power the faster it goes. I cant even think of a logical reason why its doing that
@@JamesDeanDesigns OK, Thanks. The Amazon USA does not have the same brand of power supply you recommended.
Hi james, I got the same spindle and power supply unit. I wired the spindle directly up to the power supply unit, but it didn’t spin. Is my motor broken?
Its difficult to say but it would suggest that. Do you have anyway to test the connections, such as a multimeter?
So are you powering just the spindle with that external power supply or is it feeding the board and then the board feeding the spindle? Thank you!
Me personally, I'm feeding the board and board feeds the spindle. Some people do power the spindle separately though
@@JamesDeanDesigns thank you for responding Sir! I plan on taking the same approach as to not lose spindle control
@@chrisjsmitty there is way to power the spindle separately and still control it through board but to be honest its more parts, more money, more effort. Personally not worth the hassle in my opinion
Any idea what pot to use for a manual variable speed control?
You just fit something like this in line for the spindle and that will allow you manual control. amzn.to/3p9lg7K
Is the spindle still going?
Thanks for this information it was very useful. I just got into CNC and I have a 3018pro. I was trying to engrave on a 0.8 mm thick aluminum and it kept stopping after the first character was cut, so I checked the $$30 and its showing =1000 but the spindle speed in Grbl is showing 10000 so now I think that might be the problem. please let me know if you've had this problem before and what is a good fix. Thank you.
As long as the $30 number is not higher than your spindle speed is should be ok but still best to check. Also while aluminium is a soft metal, its still pushing ths boundaries of what these machines can do. I think when people engrave metals they do really light passes like 0.1mm per pass
@@JamesDeanDesigns thanks im going to give it a try tomorrow and hopefully it works do you have a video on creating gcode using easel?
@@JamesDeanDesigns That’s what I do, several light passes at a depth that will allow the cutter to cut but not bog down. The cutter is really key, I’ve had success with 1/32” ball mills and tapered cutters with a fine point like the ones from Dremel. Experimenting is the key.
it also have to do with resonance!? On higher rpm maybe it isn`t in the range the motor chasis and the rest of the maschine can resonance on that like on slower rpm.
Should also consider ramping the spindle speed up slowly on start-up to reduce start up loads.
That all depends on what could control board you have. Ramping is one option but an easier option overall is to fit an inrush limiter which saves needing to use the ramp code for every job
I have set the $30 value to 100, so I can just give RPM values in percent.
When are you doing your video for the laser attachment?
I'm hoping this week. I have a few days off from work after an operation so going to try and do the GRBL setting calibration and the laser video
@@JamesDeanDesigns Looking forward to seeing it. My laser will be sitting in the box until you upload. Lol. Hope you have a speedy recovery man.
Why doesn't the offline controller work with it? The updated version
I don't know what you try to achieve!
I see many people changing original Continuous current motor with a huge asynchronous motor!
I can undestand it for those who work with wood.
But for myself i only need to drill PCBs and i think this CC motor is enought to start.
But since None youtuber is able to draw an electronic schematic, i'm still unable to understand how it is possible to make my original CC motor varying with the gcode 'S' commands given.
Or if you prefer with candle or grblcontrol with the Spinple Speed setting!
I think it's the same done with lasers but it doesnt not seam to be applied on CNC. Or am i wrong?
If I'm understanding your question correctly then your GRBL control board has a $30 setting, usually 10000. This is 100% power. So s10000 would be 100% power, s5000 would be 50%, and s1000 would be 10%. The % I believe controls the voltage going to the spindle. However if for example 100% power is 10,000RPM, 50% does NOT mean 5,000RPM. Its more of a curve than a straight line if that make sense
For a major spindle upgrade, just switch the new spindle motor with a relay. Use a 24V relay and plug it in where the original spindle goes. It will all be automatic just as it was before. The only difference is that you should max out the speed in software and use the motor's own speed control.
I did a video a few weeks ago on this which is basically the same process. Using an SSR to control a Dewalt router. Works great
@@JamesDeanDesigns Excellent. I shall have a look at your video. Is the SSR maybe fast enough that you can make use of the PWM to control the router speed?
I wonder, isn't it better to use a soft start now?
(I mean to boot and keep all components intact, Motor and Power supply!)
Friendly greetings from The Netherlands!

Friendly greeting from the UK too 😁 I hadnt even given soft start a thought when I bought this but a few people have mentioned it now so I think I need to look at it. Also someone suggested about breaking the motor in - apparently you run it under water fir 10 minutes and it helps the life of the motor as the brushes are shaped better
That last video... a soft starter 😜
Hey James, I'm having a problem with my 3018. When I start my file(through UGS) it runs fine for about 5-10 mins, but then it begins to waver away from the cutting paths. It then cuts off path. It seems to skip a line. Something like that. Very odd and I don't know whats going on
Sounds like you may be missing steps. This is usually caused by going to too fast or too deep. Can also be caused by your axis being a bit stiff if they are not aligned correctly
@@JamesDeanDesigns its definitely not too fast or too deep. So how would I go about fixing the axis?
@@every_thing_wood1251 have you adjusted your acceleration settings? If these have been taken to high it can also cause missing steps. For the axis, issue 5 I think in this video about 10.12 in th-cam.com/video/r-uLsMwOBfY/w-d-xo.html
Help! The spindle remained turned on at maximum speed, even when it is disconnected from the PC .
Not 100% sure but a chance your mofset has gone. Do you know what control board you're using?
@@JamesDeanDesignsSame here, it in fact did burn out the motor control on the board. It’s not the stock board, it’s still working because I swapped it out for a generic 1.1 grbl board. Oddly it worked fine with the handheld. But as soon as I used my laptop, upped the RPM TO 100% it never was able to slow it down after with any configuration. Since this is mainly for tinkering and I plan to use if it works well enough to do some metal engraving, I ordered a 300w motor that operates off its own 48vdc PS and sipped is control is through a potentiometer. As you noted, I may need to up my Z stepper power. Hmm….I think this is becoming a hole in my bench to pour money down.
Wich mainboard use you for it ?
I have the Cronosmaker on my machine

Spindle does not spin in machine 3018 why
Hi James
Thanks for the really good videos for a novice like me. I have purchased a 21000 motor as per your Amazon link. How do I change the ER11 extension rod as it won't budge from the original motor. Any advise would be appreciated. Thanks
This is quite common. The easiest way is to take the nut and collet insert off, clamp it upside down by the ER11 collet and tap the bar out through the middle with something like a screw driver. You can use some penetrative oil like Plus Gas or GT85.
For the 3018 pro, what is the mm size for the er11 collet extension…5mm?
I ordered the high rpm motor, but it doesn't seem to work correctly... When I engage the spindle in grblcontrol it turns on in a pulsating manner. The old motor works correctly.
Your power supply unit (psu) might not be strong enough to run it. I ended up buying a more powerful PSU to run it
@@JamesDeanDesigns Thank you for your reply! I found a gcode trick, that may work, but the best thing to do is probably just to upgrade the power supply.
Will the 5.5 laser ingrave Metal?
It may leave a mark on certain metals but i wouldn't say it would engrave them
@@JamesDeanDesigns thanks. I was hoping. Your videos have been great
Hello, I have a CNC3-3018 pro, i have been looking at a lot of these comments and just wondering, there seem to be different types or names of the 3018. are they all the same as far as the control boards and running the same grbl? Also I just bought the Genmitsu GS-775M and I'm trying to get it running to the speed 20000. when I try to change the $30=19000 from a video that I watched on you tube. I started low with S1200 and G4 P.25 kept going to 19000, but the speed never changed. What I'm I doing wrong. I saw on other videos there is text file to open the codes M3 S4000 G4 P.25 (WHAT AND WHERE!!!) how do I find that? I thought I looked everywere, but dident really show me how. SOOOO how do I change it? and get it running at its full potential? I think I need a step by step or a relly good video.
The $30 can be anything in theory. These machines don't actually measure RPM so you can use an easier rounded number like 1000 or 10,000. Its all about the proportion of power to the maximum. So for example if you use $30=10000 ($31 should also be set at 0) and wanted 50% power then that should in theory be M3 S5000 which literally means start spindle at a speed of 5000. The code your referring to insert is ramp code, this is basically to soft start the spindle save over powering anything. So quite quickly you 20% power, 40% power, 60% power etc. I have to be honest if all your code is correct I cant really understand why you can't control the speed of the spindle. Try using Candle. It has a manual speed controller which should help in this scenario
@@JamesDeanDesigns thanks for the reply. I'm in the Candle and I can change the speed from 100 to 1000 but I just can't change it in the console it always says $30=1000 and when I try to change it to$30=10000 or anything past 1000 it seems like the spindle just runs slower. I took pictures of the setting of the grbl on the candle but I can't find any way to send it to you.
@@rolandhoffmaster4760 so if you increase your $30 value but your S values stay the same then yes, the spindle will go slower. Using my earlier example, if you increased $30=20000 then S5000 would only be 25% power now as its all relative. If you're on Facebook or Instagram you can message me on there an send the photo if you want
I went to UGS and changed the grbl in the console to $30=20000 and I closed it and opened it back up and the 30 stayed at 20000 it would never change in the Candle no matter what I did. But I just opened the candle and the 30= is at 20000 but when I hit the spindle speed on the candle the spindle just runs like it's only at 100? James we all thank you for any advice but I know that you are not the problem solver for this machine but it seems like you are a very good teacher with your videos but not everyone is a good student. Everyone learns at a different pace especially when they jump into something they never done. So I (WE) just want to thank you for what ever device you can give. Keep up the good work.
@@JamesDeanDesigns ok so the $30= is at 20000 in the candle I have to put in the console S20000 and I will see it run at that speed? Crossing my fingers
Mine imploded after about 10 uses and killed main board
the 20000 rpm spindle is twice as noisy I can hear it running in the basement from upstairs but it seems to have more power but twice now the z axis coupling has slipped putting the coupling on the screw and not on a machined surface is bad and I have had to drill out the set screws because they are such poor quality the allen strips out I am saving for a quality cnc router and not a toy
It sounds to me like something is really unbalanced, more than like your collet setup. My 20k spindle ended up being quieter than my stock spindle. Sorry to hear you've had a bad experience
as far as I am concerned motors can run at any voltage...but the current is what matters......
Thanks for the information :)
I am aware of your answer, How ever I am trying to find out Why the 24 Volt power supply will not run the CNC, What could cause it act like it does. I have a 10sec. youtube shoot of it if you would like to see it.
my router came with 10,000 rpm and it's not enough. It sounds/vibrates at full speed.
Unfortunately a lot the routers for these machines are really unbalanced which makes them noisy. I found that putting a different ER11 Collet on helped balance things better
The volume of your videos is always too low.
Thanks for the feedback. I always play my videos back on my phone after going live and I never have an issue with the volume. Any particular sections are the whole video?
@@JamesDeanDesigns (whole video)I seem to need to put the volume on my TV up about 3 or 4 levels to equal the level of most of the other videos I watch.
@@aloneinanearthship4010 I'll bare that in mind for the next video. I dont think I can take it up much more as it peaks to high but I'll see what can be done
