Thank you for quick response
I’m thinking of returning the two trees 450 as I’m having difficulties assembling it
Big laugh, someone on eBay UK trying to resell these at £850!!
Not an authorised selling channel and effectively 2nd hand, so won't carry full warranty!!
@@JohnColgan. sadly there are always people out to try and make a quick buck 😕
would you recommend this machine for engraving in Aluminium sheets about 3 mm thick?
Well
Thank you for this video James.
Followed it to assemble mine this morning.
Definitely took more than 15 minutes for me though, but I'm guessing a lot easier than some that need a lot more assembly.
Very well packaged and they give you everything including a screwdriver! And the box with all the bits in that are all labelled up, excellent.
One slight bit that threw me, the Genmitsu on the panel where the spindle is was upside down!
Only 4 screws to undo to switch it round though.
Thank you for all your videos
Fantastic review. Super slick and very informative 👌
The 4040-XE had 2 advantages, the inbuilt offline controller and stronger stepper motors. However it is now becoming an older machine so if I had to pick I would lean more towards a newer machine such as this
So very glad you gave this a good review. I just watched this, as well as some of your other videos. I ordered this prior and it showed up yesterday. Sadly the bits did not. Now, if I can just get my head wrapped around the software, how to use it and which to use, I'll be golden!
Thank you from Appalachia and Bourbon country!
Glad its helped 😁
Stripey 'oss again. Love it. Signed hopeful cnc buyer in the future from over the hill in chesterfield.
Thank you for a nice series on the 4040 Pro. Just pulled the trigger on Amazon US.
Hope you enjoy 👍
Thank you for affirming my impulse purchase
😆 glad it helped
Love your content, James. I have been watching it all to try and decide what machine to start with as a beginner. Do you have a recommendation between this and the Fox Alien 4040 Masuter pro? They seem to be extremely similar and I’m having a hard time deciding which one. Would love to see a comparison video. Thanks!!
Thanks for this great review James. I have a 4040 and the first thing I discovered was that the spindle needed an upgrade.
Yes, its ok to get you started but more power is usually better :)
What’s a good or rather max size spindle upgrade vs a router that would fit in included mount?
And say one went with a 500 watt 52mm spindle, do need to upgrade the board? Or is it plug and play
Hey James, love the review of this CNC. Got a question regarding your stress test. Could you please share the feeds and speeds that you used for it if possible.
"Yes there is; leave it alone". LOLZ! Not only technically savvy, but quite the comedian too.
I wrote the below b4 hearing about the 2 different positions for the z axis.. I would like to see a 4th axis demo
Hi James, very glad to have seen your review after stumbling upon Genmitsu on Amazon. I had been eyeing the OneFinity CNC and I'm glad to have found this "Mini-finity" as you call it, as it may perhaps be more fitting to my projects (though the bigger bed of OneFinity will ultimately gain me more output, but that's at 5 times the cost). Given that it uses steel tubes, I assume then if I find longer tubes, I can make the Genmitsu 4040 support an even larger bed, yeah? I think 24x24 would be my goal.
Since making this I have found out Sainsmart are working on an extension, likely to me 400x800. Yes in theory you could extend it yourself. You would need the tube and a longer lead screw for each axis. Probably have to extend a few wires as well
@@JamesDeanDesigns Oh, so like the extension kit for the PROVerXL 4030. Do you know whether they'll sell it as a standalone 4040 Pro product (maybe called ProXL) or is it only as an upgrade path?
400x800 is a lot bigger compared to the ProVerXL 4030's upgrade of 400x400. I can only assume the price then would be double of what they currently offer now for the retail price of the 4040 Pro
Nice review James. This wasn't out when I bought the FoxAlien Mauster Pro. I like FoxAlien but for the same price I would have chosen the Genmitsu. If they offer an expansion kit I may sell the FoxAlien, I will wait for your comparison.
I've just deleted my last comment as Sainsmart have updated me and said they are working on an extension 👍
@@JamesDeanDesigns 2 things, extension X, Y or both? Second, which axis's have limit switches?
@@11290slk they haven't not confirmed that but hopefully they will as they check these comments. All axis have dual limit switches
10:12 morning James, do you have a tutorial on how to create the stress test file?
Thanks
My Genmitsu 4040 Pro comes tomorrow. This is my first CNC and I'm so excited to get it. Do you have any pointers to get Carbide Create to work with it?
Very nice review, I have seen where some people say there is a lot of flex in the tube rails. Have you experienced much of this in your work with the machine? Thank you Bill
Not on the Y axis. The only time I really saw it on the X axis was when doing 5mm deep cut but there was a lot of pressure for obvious reasons. They probably could have used thicker steel tubes but equally then the weight goes up, the price goes up etc.
Would it be difficult to add a 4th axis, a rotary to this?
Hey James. You mentioned a sanding brush for getting into the fine details on the clock. What do you use for that?
Nylon sanding wheels

Hi James. I know you are at a stage with your channel that doing reviews are a good idea. What I would like, as many others would, is for you to decide on and then use some quantitative and qualitative assessments which you can do. This would mean that each cnc can be compared with at least a similar price range or similar specification machines. As the assessments are not a personal opinion you should be then be telling the manufacturers what your standard assessments are. By continuing your current “everything is really nice “ “this is not a good thing “ . As I am trying to figure out what Cnc to buy I come away none the wiser in spite of watching all your builds/reviews/in-depth videos. I love your work but now you are becoming the goto channel for Cnc content I think a more scientific approach with a downloadable file (for Patreon) to use as a comparison between Cnc S to find what’s right for you.
Hi! Do you think it is possible to make small detailed pieces such as a 75mm height chess knight with the rotary axis? Thanks.
This is very tempting. Looks like it could be easily extended using DOM too. If this were 600x600 id jump on it right away.
They are making an extension kit but suspect it will be 400x800
@@JamesDeanDesigns I heard about the extension kit as well.
Not sure what to do Ideally I want 600x600 but the price of the 4030 upgraded to 600x600 is at the point where I could do one of the various bees or lead machines out there. I still may try one of these and diy some extensions. I believe I could easily strengthen the X gantry too.
Hard choice to make Ive 3d printed for years and converted one into a very weak cnc and I really want to get something better and really get into it but for a lot of the things I have in mind I need a bit more space. Would not mind getting a small super stout unit for aluminum though the 3020 looks good for that. The 6050 looks amazing but at that price I would need at least 600x600 since Id want to do both wood and aluminum on it. I think extending that one would be possible too but the cost to do that would make it kind of foolish to do.
Other optiona are to go up to one of the more pro machines out there and im not sure im ready for that kind of investment. Or try one of the 6060s built the same way as this but with 3 tubes on the X axis that are popping up.
Ah decisions decisions
James, i am looking at the sainsmart 4040 verus the fox alien 4040. I need to clear up one point. I currently have a 3018 which is screw driven and have had little or no problem with the movement portion of the machine. It does limit you due to the smaller size. I am very comfortable with a screw driven machine. I worry about a belt driven machine ( maybe unnecessary ). I do some laser work but currently olny have a 2.5 ( optical) laser. My plans are to buy the machine and ad a 40 watt laser later. If you could shed some light on best chose for me i would appreciate appreciate it.
Hey James, if I want to upgrade to a 500W spindle, do I need to get a power supply or can I use the same power supply?
Could I buy bigger aftermarket guide rails and lead screws to make it larger ?
Hi James, which one between Vevor 6040 and Genmitsu 4030 is the best? The 6040 seems 2 times more robust.
More useful to me would be a review/demo of the machine with its original spindle.
Hey James, appreciate the videos. I am upgrading to the Makita RT0701C router this week. I watched your other video about upgrading to a router, does the end of the extension cord still get plugged into a power source, or did I miss something? I know you had to take the plug off to get it into your enclosure, I just wanted to double check before I end up doing something wrong.
If following the video, I wire the SSR into an extension lead to save voiding the warranty but ultimately it still has to be plugged into the wall either directly or with an extension lead.
Awesome video I always learn something from watching them. Can you link the file for the Z-Probe 3d printed box?
Thanks. I thought it was in the description but clearly wasn't 😆
www.thingiverse.com/thing:5888374
Hi how do I find my z axis length please on the 4040
At 5:58 you mention that the drivers are fixed and cannot be changed in the black box. If I were to upgrade the Nema 17 to the Nema 23 would I have to change the drivers? I can drill new holes or make adapter plates for them but that is not the issue I am faced with. The drivers on my 3D printer can be replaced but these cannot. So my ? Is will these drivers work for the Nema 23’s?
Do you need a separate power upgrade for the higher power options like the laser or router? If😢I know the FoxAlien needs a separate power supply for the 40w laser
Looks quite impressive. I assume it is GRBL can I ask what software you are using please?
Yes it is GRBL. I use Carveco and UGS
Thank James. Would this machine power a 300 or 500w spindle directly?
Im 90% sure it will not power it directly but let me check with Sainsmart
Firstly many thanks for such an amazing video.
I recently bought this machine and wana start my first project like the one you made of Zebra. i just loved that one.
Is this possible for you to put a video with detailed steps to create that art work i. e which, software you used, machine setting, spindle type, how you created svg file etc etc. I wana to start my journey with that artworks and your Guidance Sir.
Thanks a lot in advance!!
Yes, I already have a video out for it.
ua-cam.com/video/FCoF20IToqo/v-deo.html
is it possible to access the PWM output on the controller to be able to use it to trigger a solid state relay (for a switch for a plasma cutter)?
The laser output has PWM so I would imagine that should work. People use this to run their spindles from a VFD so similar principles I'm guessing
Hi James. My name is Yves and ive got a bad hand wirting in englis. sory for that. but i did purchas a genmitsu 4040 and it is very slow on the Z axis. wonder if it can go faster. And to make it go faster. From Canada. Thanks for all of your reviews.
I prefer linear rails. It doesnt look like enough z for a 4th axis.
What is the cnc behind you?
Morning James is there an extention kit for this model?
There will be one coming. Just not sure when.
los motores de mi 3018 se han quedado agarrotados,apago el sistema y se desbloquean.No se que hacer.Gracias
Looks like a fantastic value in this machine. About 800 or so usd once you get the makita or a carbide3d router (same, cheaper, no extra parts, longer cable, 80 dollars) & the adapter. A great entry for someone who maybe wants to get a onefinity later. Excellent entry machine for someone who wants to start out, learn, then make some money for a full on onefinity setup. this is coming from someone who has a stepcraft d840 and a shapeoko pro xl. This genmitsu looks a lot like the belt driven FoxAlien machines in this range, excellent value over those.
Hey mate, i was ready to go buy the Stepcraft D840 but this being my first machine, i may be thinking its better to just go with the Genmitsu first, and if things go well move on to a d840. Onefinity isn't available for europe in a logical price.
It is a great machine for the price, and super easy for beginners :)
@@leogiouldasis5063 IF a d840 is in your budget & you are passionate about this kind of thing, I would actually start there. The new versions (stepcraft3) are fantastic upgrades over mine (stepcraft2). IF you are not sure, I think it is worth ordering a Genmitsu product on Amazon Prime for the return policy “just in case”. Having not had hands on it, yet being very, very displeased when I tried out the 3020 Pro Max (completely different machine, this one in James’ video looks way better), I was glad I got it Prime so I could send it back. It is worth a try as long as you have peace of mind with a return policy. I do not know how good home-base in Europe stepcraft support/sales people are, but here in the states, the US headquarters has done very well by me many times, they will talk on the phone & help you with anything that is confusing or whatever. Keep in mind the cost of the stepcraft includes Vectric Vcarve Pro & UCCNC hardware/software, so that is one reason it costs a bit more, those are expensive on their own.
Hi. Can it cut 3mm Carbon Fiber plates with the standard spindle? Or stuff like 3mm plywood?
Ply yes, may need to take a few passes to do it but it will get there. Not sure about carbon fibre as I've. Ever cut it but probably yes
I’m torn between this and the 4030. Main reason for wanting the 4030 is due to the fact that I can upgrade the workarea if need be. I’m used to a 30”x30” area from the Shapoko. But I hardly use that much space and I still have access to it at my local makespace should I need it. 90% of my projects are done on the workarea of this maschine. But I want a rugged machine that grows with me as I get more advanced. Currently not doing any 3D work, but plan to in the future. Is the 4030 worth the extra $350? Especially since I read here in the comments that they are working on extensions for this machine. I have to say I don’t do any metal work. Only wood. Hardwoods primarily such as maple and walnut.
The 4030 is a more ridged and powerful machine so yes it is worth the extra. The extension kit for this is likely to be 400 x 800 but will still be with Nema 17 motors. The pricing generally gives it away of which is the better machine, the 4040 is still go but likely to have to go at slower speeds than the 4030
Thanks man!! I was about to cancel my 4030 Order to get the 4040. I was unsure how good rails on wheels are. But it should also be easier to modify it.
Hey James, is it possible to usw a MPG Handwheel together with a Computer at the same time?
Thank you! : )
I believe so but not 100% sure to be honest
Any thoughts on using the 69mm collar + Dewalt DWP611? I see the Dewalt is quite a bit heavier than the 65mm + Makita you chose for the video. Yet, Sainsmart does offer the 69mm collar so perhaps that 4040pro has enough capability to drive the DWP611? Appreciate any opinions / insights you may have on the front.
They offer both as the Dewalt used to the the goto router for CNC. The problem is in the USA they started using softer brushes in the Dewalt routers so a lot of people moved away from them over to other brands like Makita.
In the UK the Dewalt is about twice twice cost of the Makita so personally I would go for the Makita
Hi james
I was wondering about what software does it use
To run the machine, any of the most common ones such as UGS or Openbuilds Controller.
Similarly for design, most of the common ones such as Easel, Fusion 360, Vectric and Carveco. This video runs through them
ua-cam.com/video/EMI97Rcb0bQ/v-deo.html
How do you compare this to the 4030 Prover XL?
Whilst this has some new, nice features, the 4030 is technically still a step above this.
My 4040 keeps stopping in the middle of roughing out a 3D carving. Any tips?
You need to understand what's causing it to stop. A lot of things like this are actually PC related and not the machine. Make sure all powersaving setting are turn off like going to sleep. Disable a function called Selective USB Suspend as well as this is a big pain
Sorry if I missed it, but where can i geht the files for the clock?
I can't remember which one as I downloaded it a while back but will have been one of the free sites I list on here ua-cam.com/video/y8-c756Hk7o/v-deo.html
I can't seem to find a lot of information on how to get from an STL file to the file format needed for the 4040 Pro, or at least in a way that I can understand it LOL I have basically a trial version of Fusion 360, and I can get to the point where I can select tools and such, and tell it to generate a tool path, it hangs at like 91%, and I've left it to run for well over 12 hours and it never moves past that point. Does anyone have experience with creating an STL and getting it into the Genmitsu file format so I can try testing my design in the machine? Or an actual step through on settings and such that are needed to convert it? You'd think since I work in IT and have experience in a myriad of different technologies both hardware and software I'd be able to figure this out, but I'm stumped, and the 4040 Pro right now is a dust collector in our garage.
Nice and thorough review, and a nice looking machine. I think I still hanker after something that can do 4ft boards though. It is hard to tell from the photo but it looks like this is still using the notorious WCH serial chip. Do you have to install WCH drivers for this machine ? These drive me crazy. I thoroughly disapprove of the shady practices of CP & FTDI but as much as I want to like WCH, sadly my Win10 laptop just loses sync with WCH chips on a long run and this is widely reported on the interwebs as "a known issue with no fix". B.T.W there is no 'e' in hors.
Truthfully, a lot that goes over my head, I don't have much knowledge of it. You have to install 1 driver (CH340SER) to make the machine work, but I've never had the issues you mention and I'm also on win 10, ran jobs for over 8 hours without a hitch. But as I say, when it comes to chips and circuits, I'm out of my depths
@@JamesDeanDesigns Yeah, that's the WCH. I don't know why a machine costing hundreds of pounds needs to make the few pence saving. Not everyone sees the issue, maybe the laptop I was using was a bit under-powered. But I took to using Candle on a Raspberry Pi 4 and I've not seen it since. Another thing that works is to get an FTDI adapter and connect the serial to the "offline controller" port ... if you can find the pin-out of that connector (which I founder harder than I expected).
Oh it does resemble onefinity if you zoom wayy in. Haha, that's about the end of the similarities though I think
I'm sorry if I've missed this, but I can't find the exterior dimensions anywhere? Can someone tell me how much space it takes on a table top?
I have a small workshop and need one dimension (preferably width) to be less than 26 inches......
About 1.35 into the video, footprint is about 700x700 so just over 27 x 27 inches I'm afraid 😕
I ordered a 4040 pro and I've also got 4 spare NEMA 23 motors it possible to swap the NEMA 17 out for NEMA 23?
It's unlikely but depends on what nema 23s they are. Chances are the control board will not be able to provide enough juice
@@JamesDeanDesigns yeah i was thinking the same thanks.
What's the full weight of this machine?😊
what controller board comes with that and will it support Mach3, and/or does it come with software?
It's a custom control board that runs GRBL. A lot of CNC machines have moved away from Mach3 now because its outdated and GRBL is opensource so doesn't cost the user anything
Thanks a bunch that's great to know!!
will it work on a Mac book pro
What is the footprint dimensions of this CNC? I can’t seem to find it anywhere. I have very limited space and want to get one and build a enclosure for it
Ok never mind. You just said it in the video
Thanks
All sorted before I even had chance to reply 😁
i always wanted one of these but what stops me, is that i have no clue how to set up the software to make is carve out a pattern
Loads of videos on my channel talking through every step. Also joining the Sainsmart Facebook page as its full of really knowledgeable people to help pretty much 24/7.
It's a big leap to take but just take baby steps with the learning curve and you'll get there
Hallo nice machine but can you Test a stepcraft M series.
Would be nice
I would LOVE to...I just can't afford a Stepcraft. You should tell them to send me one 😆
@@JamesDeanDesigns I'll Tell them.
But do you know the story of stepcraft?
Well it was as German brand and since view years it has expanded to America.
It's a pretty big company now in Germany as well as in America. Or maybe you can test a slightly cheaper machine from stepcraft like the d420 or d600 or d840.
Would be very nice because I don't know which I should buy because of rigidity of the machines.
@@rolandrethati2549 before my Instagram got deleted, I used to follow them and they also followed me. I've wanted one of their machines for ages. Maybe I'll get there one day
Not available direct in the UK at the moment unfortunately
It was, but they sold. Its still available on Amazon but shipped from the US, however the price jumps up quite a bit I believe
@@JamesDeanDesigns yeah do you know when they might come back?
Now available directly and the flash sale is still on - Sainsmart Genmitsu 4040 Pro - Direct - shrsl.com/3x4v2
That’s good. 15 minutes to assemble it now. Try to get it to work don’t bother calling Support you’re pretty much on your own.
Support doesn't have a phone number. Best option is email or Facebook messenger. But you'll also get a lot of support in the user group.
Tubes are for lawn furniture.
Tell that to the makers of Onefinity, probably one of the best selling and best rated machines for its size 😆
Looks like it’s sold out in the UK :( :(
It's been a popular. They will get stock back in soon hopefully
Amazon sell them but they are now £800+. I bought mine a few weeks ago for £700.
@@JamesDeanDesigns hi James have you had any issues with the machine Other than user error?
This morning i was running a job and the machine turned off and on three or four times repeatedly after running for about 45 mins Resulting in the job being out of sync.I stopped switched it off and left it for an hour. As the blue light would not come back on. Came back to it. I have run the programme again and it is still going as i’m typing. What on earth could have caused this? I have emailed sainsmart just to let them know and to see what they say.
Also how hot do the stepper motors get? The z motor is really hot to the touch. my spindle housing bushes have started to fail already. Sainsmart have sent me a new one however it was for the prover not the Pro. So i’m currently waiting for them to fix this. The reason for them starting to fail could be due to a few massive mistakes/crashes on my part.
As you are aware i upgrade to the 500watt spindle (which snapped in half) and i am currently using the 24v 20000 spindle you did a video a while back. I don’t really want to get a router just yet. However i can see that upgrade coming shortly. Another cracking video and very informative as usual. Since upgrading the spindle i have noticed that the bed does not seem to flex or vibrate as mush as it did with the stock spindle. When i come to changing the boards i will look at adding that extra piece to help stabilise it.
Now available directly and the flash sale is still on - Sainsmart Genmitsu 4040 Pro - Direct - shrsl.com/3x4v2
$600 U.S, £800 U.K. , that’s fair isn’t it, should be around £500 U.K.
$600 is the base price before tax and delivery as that varies between countries. For the UK £543 base price, then £650 after tax and delivery directly from Sainsmart
You guys always show it with a Makitta, it DOES NOT come with a Makitta.
AT NO POINT DO I SAY IT COMES WITH A MAKITA. What I say about half way through the video AFTER SHOWING THE KIT SPINDLE is that the machine benefits from being upgraded to something more powerful. A router can be as cheap as $50 and nearly 10 times more powerful than the kit spindle so well worth considering as part if the overall purchase

would you recommend this machine for engraving on aluminium or stainless steel sheets about 3mm thick?
I'll start by saying these machines are not designed for metal but in some cases they can do it. If your goal is metal all or most of the time then look at something like the 3030 Pro Max or stronger. If your goal is wood with a bit of metal then this may work for you. Aluminium it will do, lightly engraving steel is possible but may not be as clean as some more rigid machines
