In my opinion you are creating the best reviews from all the TH-cam content creators that I am following. You put so much work into your reviews. Such a big amount details. Very detailed, structured and an academic approach of testing the features. Chapeau! Now I really wish I could afford the Carvera. ❤ from Katja
Dear Aurora, here is the two cents of an early CNC mill user. To benchmark the capacity of a milling machine, you usually want to do things differently. Every milling bit have a cutting capacity for each of its tooth. Every serious milling bit manufacturer gives the proper dimension of the chip to be cut by one tooth on a single rotation of the bit, and some other interesting information like the cutting speed, and proper RPM for every material, but let's keep it simple for a better understanding. Let's say the bit have a 0.2mm chip capacity per tooth. If the bit have two teeth, it can cut 2*0.2mm per rotation. If the asked spindle RPM is set to let's say 6000, the bit is able to cut 6000*0.4mm=2400mm per minute. So you get the optimal feed and speed of the machine for this bit. There's online feed and speed calculators, but there's nothing like the bit manufacturer informations, because the cutting angle or the spiral shape of each bit matters. The depth of cut is usually told by the manufacturer too. It generally never exceed the half of the cutting tool diameter. Now you have all the required parameters for the optimal use of the bit. A capable machine would do a perfect job at the bit's requirement. If the machine is shaking and/or if the cut quality is not clean and/or if you break the bit, the machine have probably structural issues : mostly cheap or inappropriate guides/transmission and/or flexible structure. If you hear the spindle decelerate when you start diggin in the material, it may have a lack of power. You don't want your spindle to slow down when machining because, according to what have been told above, as your spindle slow down your feed will be too high for the bit's specifications. Last, to make rubbish machines "work" (3018, etc.) you can't even run at the bit's requirements, except with smaller tools and/or very soft materials. So you have no choice but to slow down the feed and set a very thin depth of cut. That's wrong anyways because the bit will heat up and may also burn the material. It will get dull quickly, and the machining time will raise exponentially, so will the wear of the machine. In a review, most TH-camrs are making the mistake to duck the machining parameters to get good looking results, so they give the false impression the machine is fine while it is obviously not. I really like your videos and appreciate the care you put into it, by the way. This is very impressive for a young lady, let me tell you. Regards. P.S. a 3D printed cap to protect the laser lens during milling is probably a good idea. 😉
Well explained, that is why our machines are heavy, they have to be very, very stable and heavy. People sometimes do not realise that they can´t cut steel properly (industry quality) on a aluminium machine. Especially not with that 200W spindle. The torque due to the cutting pressure on the bit at lower rpm´s and feeds will be too much... If you wanna go steel and other metals cutting milling them properly, you have no choice but looking for a industrial machine or build your own with steelframe, maybe even servos and a water cooled spindle. Furthermore you need lubrication, so the machine should be sealed for that issue. The biggest lie i read here on YT is you need a spindle up to 25.000 for cutting steel and stainless steel... This is wrong like the poster showed!! When my parts start vibrating im going UP with feedrate and lowering the rpm as a first reaction!!! Machines like the Carvera are just not capable of that cause they´re too weak build with a too weak spindle motor. The harder the material, the lower the rpm as a rule... Cutting pressure of the tool increases very much then, so the construction of the machine itself needs to be very stiff which aluminium just cannot provide... Too much vibrations, too less torque of the spindle... This is why you could maybe... Maybe get through with an carbide endmill about 2mm diameter i guess. Machine possibly can stand it, spindle maybe has enough power? So there is many "maybe´s" hidden there... The machine looks top notch but sure istn´t designed for hard materials like steel, stainless or similar.
It’s temping. I have a 6040 router with a “2.2kw” spindle at the moment. An ATC would be great, but not sure I could live with a small work area and lower power. What I really want someone to sell is an ATC kit for a router like mine.
@@SeattleShelby while a CMM should be a trustworthy metrology instrument, i always manually verify it's claims. After checking when it states my part failed, i found it was in tolerance. Don't always believe what it tells you.
Thanks !! It was very helpful and I learned a lot from your video. You made me purchase this machine for my own prototyping/engineering ❤ quality content!! Congrats
That looks to be a nice little machine and an awesome review as always. Thank you for taking the time to make the videos, you're doing great and deserve more subscribers, i'm sure they will come.
Small but looks capable. The auto tool changer is a really nice feature. It's great that some features from 3d printing are making thier way to subtractive manufacturing.
Another well done review, as always! Thanks Aurora! Love this machine, unfortunately can’t justify the price... 4K + taxes and customs fees. I need a CNC in my workshop just to mill some small aluminum and carbon parts. Carvera looks almost perfect for that, maybe a bit underpowered. To make PCBs would be a nice bonus in case you need something made quickly, I still prefer to order them from China, they’re cheap and much better quality than homemade ones. For laser engraving I prefer to use a proper co2 laser, would be useless to me.
I must say. I never gave this channel a chance because of the monotone talking. However, I have been struggling making my own things as a beginner in cnc. This is by far the best video on how to get started using the manufacture option in fusion 360. Thanks a lot!
This is my first time watching a subtractive manufacturing video on your channel. Unsure if you have this knowledge so I'll share. I know you're testing the machine, but aside from work area clean up, keeping chips out of the cut is important to tool life. Letting chips build up means your cutter is re-cutting already cut material increasing tool wear as well as increasing the heat as you usually want chips to carry the heat away from the part and tool, but now they're still in the part. It looks like the machine came with some AlTiN coated bits, I wouldn't use those for the materials you'll be cutting on the machine and I doubt if you do machine steel the machine has enough power and rigidity to take advantage of the increased feed rate from the coating. Aluminum will want to bond to and destroy the AlTiN coating, kind of an oversite on their part (or telling on how much the company knows about machining). You'll want to keep it to bright/uncoated or ZrN coated tools. NYC CNC has a video and possibly an excel download so that you can calculate the power needed for a cut if you really want to push the spindle to it's limits. He also has videos on using masking tape, superglue and scrap for fixturing to avoid having to use tabs. I want it to be clear that in the 1mm DOC pocket, the dimensions of the pocket being off is not an indicator of machine accuracy. Due to having to use a large aspect ratio tool, it will have increased tool deflection, the only thing that would need to be changed is rough at those current parameters and add in a finishing pass or a spring pass (no added radial cut, just another profile around at final dimension). You could also change to a high feed mill which would have a short flute length but longer neck (as well as being bullnosed). The small flute length keeps as much solid material in the tool as possible increasing rigidity, you take smaller DOC at high feeds for the same material removal rate. For the files, I know most people know expect small (MB) files to be easily uploaded in 2023, but machine tools work on relatively small amounts of data unless they're large sophisticated machines. The CNCs I have access to only allow 1MB files before giving an error and really you should shoot for 800KB, which is a locked setting (software) that you could pay $1000s more for to allow for larger files to be used (2 or 4MB?), though through the usb it's as fast as a regular drag and drop on your computer aside from the interface used to go from the usb to the machine. One way you can avoid slow uploads is to cut your operations into subsections at a tool change creating smaller files (while you wait for the firmware update).
I've been CNC and conventional milling for years industrially and this is nonsense, You think a tool cuts a sliver of free swarf rather than knock it out of the way? The only time this is true is with tapping or milling blind slots or holes when swarf can build up. This machine cutting if you raise the cover prevents you blowing swarf away then so you'd need to pause it.
Now I want a CNC machine. Aurora can you do head to head competitions between rivals? I have analysis paralysis on several of the machines you've reviewed. I would like to see the Saturn 2 vs Anycubic D2 with AA fully utilized to see who is truly the detailed resin king. (There are claims that the Texas Instruments D2 tech is superior in detail but you need AA turned on) I would like to see the Creality CR10 S5 VS Neptune 3 Max to see who is the best big format printer. (The S5 500x500x500 is bigger but is the new Neptune 420x420x500 superior in results on prints that use the whole print bed?) I would like to see a speed/high temp materials competition between the FLSUN V400 and the Bambu X1 Carbon. (Both have a 300℃ hot end and both are fast. Push the limits on both.) In these competitions it would be nice to see one displaying an advantage over the other or if they run neck and neck it would be nice to see which one offers a greater value in their respective prices.
Nice review, your suggestions are spot on. I'd like it to have it's own screen though. I worked on Mazak and other industrial CNC mills for years and auto tool changing is standard but wasn't expecting it on a hobby machine. I'm wondering it it also taps threads? FYI the rear of a clamp should be higher than at the component, then the force is downwards not at an angle. Stepped or swan neck clamps are good for that. That 4 axis, also not expected and so good too. I'm wanting one of these :)
Huh, weird... I just wrote an in-depth reply to you directing you towards info and resources that could make the purchase of this machine very possible for someone with a disability. Especially if they have access to veterans related programs and resources as well but.... it got deleted somehow? Maybe because it had web links in it and the spam settings blocked it? I don't have time to rewrite all of it now so I hope the condensed version, without links helps. Anyway, as a disabled person myself who recently funded a startup on a shoestring by using some of these resources I hope you will at least look into what I post. Having disability is no longer the barrier is used to be. Unless you are physically unable to use that machine there's no reason you can't own it so don't sell yourself short. I can't go into as much detail as my first post but... First, reach out to local micro business development centers in your state for help with things like writing a business plan they are normally state run or the state may hire the service out to another agency. If there are none reach out to a nationwide volunteer organization made up of retired business owners / leaders called SCORE (Service Core of Retired Executives) who can set you up with a mentor. Both agencies can can do everything from help you write a business plan to directing you to resources and in some cases funding. That funding may be low interest loans or grants from state, federal or private sources. I was about to find a grant to get me started which reduced the amount of my loan. Second, take advantage of the Vocational Rehabilitation program, they don't just help disabled people find jobs they can also use their resources to help you start a business including with funds if you have a good business plan in place and you can convince them of your idea (up to $2k). Do the same for the Veterans Administration and take advantage of everything they can offer. I'm sorry my original comment got lost but I tried to post the main gist of what I said in it. I didn't start up a business to make a fortune, I did it to keep moving and slow the progression of my disability because keeping busy helps. It's the whole "A rolling stone gathers no moss" philosophy. Even if you only make enough to pay back a business loan it would be worth it because it will stop the negative thoughts that fine with feeling there are no options. Thank you for your service and I hope I have been of some help or inspiration to give it a shot. What have you got to lose?
Hey there. Excellent job. I've been showing my daughter (16) some of your videos. She finds them very interesting. You're very professional and coordinated. This review was excellent, covered all of the points of interest for me, for this product. I will undoubtedly be adding this to my toolbelt in the future. Thank you so much. I look forward to more content on hardware like this from you.
This is a pretty amazing review and great analytics on the End. Makera should take all 5 suggestions seriously and offer a 20-40W Laser optional on top. Then They got me . Thank You for this review!
As a retired machinist, I can see that this is a very good machine for small work pieces. It does a very good job milling aluminum even at a 1mm depth of cut. There is some chatter in the corners of the slots milled in the aluminum plate at the higher depth of cut. To reduce the chatter, a shorter end mill will do the trick. But having a small work area, it wouldn't be big enough for most of the parts I'd like to make with a CNC milling machine. I have an old manual Bridgeport that I use for my hobbies. It's a great and versatile milling machine, but it's not CNC which greatly reduces the type of parts that can be made on it. Oh well, I'm retired, but I still enjoy the equipment I'm able to afford. Thanks for a wonder review of the capabilities of the Carvera CNC Machine.
Great video, girl, a lot of work! One of the best reviewers on YT. On the funny side, I anticipated that flat nose issue, albeit I never used a CNC machine and I didn't know what model will be cut (but I work in industrial products design and our factory has some large CNC machines too). I couldn't stop laughing when I saw it. I love that you show all the process, and don't censor out the mistakes you make (well, some of them at least 🤪), this is a very good way fot you to teach, and for us to learn from these part-reviews, part-tutorials. Kudos!
27:16, look how far the end mill is extended from the collet, and also notice the flute length/cutting edge of the end mill. After I posted my first reply, I came back to watch this part again. The finish of the first slot is better than the last due to the depth of cut. Even though the end mill is small in diameter and it's extended possibly an inch from the collet, a very good finish could easily be obtained by taking a light climb milling cut of 0.005 thousandths on the edges of the slot. But, a shorter end mill at this diameter is always best for achieving a better finish.
As a retired CNC Machinist, I just wish I had the $4K available that isn't already earmarked for needs and not wants. The laser engraver even looks good enough to etch 305 x 305 x 5 mm granite or ceramic tiles with copies of books for SHTF storage and rebuilding our tech knowledge base. If enough sites are created even the morons in charge can't destroy human civilization with a WWIII
Hey Aurora, great vid as always. I was just wondering what you think about the Makera and Snapmaker Artisan. Which one should I get? I'm completely new to CNC and Laser engraving, but i need one to manufacture foam cars for F1 in schools. But it would be nice is it were more capable than just being able to cut foam XD. Anyways, please let me know your opinion on which one is better as, primarily a CNC machine but also a laser cutter. Thanks!
It is a shame that the tools cannot cut a chanel at least 100-120 mm in depth. Then DIY home built jet engine builders could make their own centrifugal compressors in the 200-280 mm diameter
hands down the best reviews on youtube! big thumbs up! question: if i also want a 3d printer: snapmaker artisan 3 in 1 or the makera carvera plus a bambulab p1s? solely for hobby purposes, i can get the artisan for around 2.3k while the carvera and printer combo would come to around 5k
30:07, Look at the radii' at the end of the slots from the first to the last, this is what I call chatter due to a heavy cut with a long, small diameter end mill. Yes, it's not bad looking, but all the slots could look uniform with a light climb milling pass on the edges of the slots..
Holy shit this is amazing. If I had one of these I could make my exoskeleton way less bulky. I'm over here printing parts for custom linear servos out of petg lol. If I could make them out of aluminum they could be so small and still strong af.
hi princess the egyptian model was cut to perfection. that particular cut is spiritual and not software. it has nothing to do with g code. the nose and ears are missing because it is true of most egyptian artifacts of today i value that particular cut as exceptional with a high value mark up. it should really be on display and i hope you did not throw it away. the sphinx or most egyptian artifacts have their nose missing etc. i hope you did not throw it away sincerely ejike
Hey thank u for the awesome review. Liked and subbed. A you please tell me if it will be worth and investment for creating art products like bust statues of metal ? What’s the maximum size I can do ?
I don't think this machine can do that, as the 4th-axis is not strong enough to grip the metal for engraving. However, it should work well with wood, resin, and other softer materials.
Thank you for such a thorough and detailed review. As a machinist I am impressed with your knowledge on this machine and G code understanding. I have this CNC in my future possibilities. This review helps me decide this is #1 on my list!
Hi, Mechanical Engineer here... Working on a 33t 5-Axis with Heidenhain ITNC530 and searching for something as a "toy "at home... My oppinion: Perfect Video ♥♥♥ Very sympathic lady not giggling or making fun but bringing out facts and knows what we wanna know about, thank you lady, if i wasn´t that far away, i´d like to invite you on a coffee for this video! ♥🙂 Thank you! Kind regards from Austria
10:18 This corner was high when probed, but deflected downward when milled, reducing depth-of-cut. This deflection is a risk of using a compliant wasteboard without adequate clamping.
Please check out the HX-8610 VMC. It’s made in America and is mainly sold to the education sector. Fully enclosed and cuts steel. At a price point of $5700 it’s worth a look. I’d love to see your opinion on it 😁
Hey there. Love the review!! I am about to buy this machine but have some questions and seeing if you can answer them. I would like to know the following. 1. Can the 4th axis be used with the laser to etech say thermos or water bottles or even your part. 2. Can the laser etech anodizing or say powder coated or etch brass? 3. Have they gotten back to you on youe upgrade suggestions. You were spot on with those. Thank you so much agian for the great review.
A very Good Good GOOD review of CNC. Just see the serial model who become but for now, it's very good price for this quality and capabilities. Thank you for your time and this vidéo ! Kiss from France
What is the collet size? ER-11? What about milling aluminum and brass? I need to make parts for a machine, parts have holes and tap threads, is out possible to do this on the machine?
This is the best review I have seen of this machine! I really like how in depth you went, especially the section on aluminum. This review is what lead me to purchase a carvera. Long time subscriber, you are wise beyond your years, Destined for greatness.
3d printing is cool, but plastic just doesn't cut it sometimes. This is a very cool machine, seems very well made. but out of most hobbyist' price range imo.
This is an excellent review that fills in several holes and provides additional support in "how to" setup our new machines and controllers. Quick note, the link for the CNC vice does not connect to the same vice, is it still available? Thank you!
thanks but still have a question, as the board is fixed and under the board there is metal,when making drilling for the board, the drilling bit will not broking as it will touch the iron base when drilling the board. thankd
$4000... Going to have to give this tech a little more time to get down to a price I can personally afford (sub $2k range). A ton of possibilities though, looks amazing!
Are you still enjoying this machine? What is the maintenance on it like? Thank you for doing the Al stress testing; none of the other reviews I've found do more than the demo parts included with the machine... which have undoubtedly been optimized for the machine.
Thank you for taking the time to make this review, I found it very informative and helpful. Do you know what size tablet the Makea Carvera tablet holder accommodate? Also which Widows tablet did you get for it?
I am using an old Dell Latitude 7275, which has a 12" screen size. I purchased it from eBay for approximately $150. I believe 12" is the largest size it can hold.
Is there any chance you could make a video review on the Laserpecker 4? I’m curious to hear what your view is and think you provide great content would be much appreciated!
Some of my questions I had concerning the Laserpecker 4 and company Im general is how well there customer service is, how well their app works and if it’s conveniently compatible with iPhone. I’ve been considering buying one and hesitant whether it’s worth it starting up a small side hustle business. Maybe I should go for one of the bigger co2 lasers, would be nice if you could do a video on which of those are best overall also! Really appreciate the aspects and content you deliver to your page!
For a router, yes. For a mill, it's pretty generous. For a general maker tool for PCBs, and components for desktop projects, I think they've got it about right. I use a homemade CNC router and am currently investigating adding an auto-tool-changer, but it's definitely not easy, so kudos to Makera for delivering all this in a prebuilt machine.
Hello great video im a long time subscriber. Im a tool and die maker and Manufacturing engineer in California. You guy do such a good job and i regularly learn from your videos. Like always great content and i wish u luck on the success of the channel
Hello! I just wanted to give you a heads up that you put this video into the lager engraver playlist, in case you want to move it to the desktop CNC playlist. Have a great day!
This is worrying - I also posted a comment yesterday and I can't see it (it was about the Makerdreams Evo One Pro CNC being another machine in this price/capability range and worth reviewing). Aurora, perhaps you could suggest another way of sending feedback that is more reliable?
In my opinion you are creating the best reviews from all the TH-cam content creators that I am following. You put so much work into your reviews. Such a big amount details. Very detailed, structured and an academic approach of testing the features. Chapeau!
Now I really wish I could afford the Carvera. ❤ from Katja

Look at the stepcraft Q series for larger with ATC at a reasonable price. I just got the carvera and am ordering the m700 for doing mobile inlays
My grandpa used to own a machine shop and he’s just amazed that for small parts, this does the same thing his half million dollar machines did.
Everything looks great until you put the part on a CMM. That’s when you see where the extra money went.
The absence of a cooling system may lead to the possibility of heat-induced deformation in the metal.

Quick change is an alternative. I had that on my X1. Some guys had modified it to auto change. No longer made.
Cnc machines have been using automatic tool changers and probes pretty much since their inception.

I would like to see the Saturn 2 vs Anycubic D2 with AA fully utilized to see who is truly the detailed resin king. (There are claims that the Texas Instruments D2 tech is superior in detail but you need AA turned on) I would like to see the Creality CR10 S5 VS Neptune 3 Max to see who is the best big format printer. (The S5 500x500x500 is bigger but is the new Neptune 420x420x500 superior in results on prints that use the whole print bed?) I would like to see a speed/high temp materials competition between the FLSUN V400 and the Bambu X1 Carbon. (Both have a 300℃ hot end and both are fast. Push the limits on both.) In these competitions it would be nice to see one displaying an advantage over the other or if they run neck and neck it would be nice to see which one offers a greater value in their respective prices.
Saturn 2, Neptune 3 Max, and Bambu X1 Carbon are the better options imo
I want one! Great review as usual. Keep up the great work!
Nice review, your suggestions are spot on. I'd like it to have it's own screen though. I worked on Mazak and other industrial CNC mills for years and auto tool changing is standard but wasn't expecting it on a hobby machine. I'm wondering it it also taps threads? FYI the rear of a clamp should be higher than at the component, then the force is downwards not at an angle. Stepped or swan neck clamps are good for that. That 4 axis, also not expected and so good too. I'm wanting one of these :)
Hey! It's the Makera Carvera Auto Tool Changera machinera reviewed by Aurera!
Great review. As a disabled veteran I will never be able to. afford one so I live vicariously through you. Keep up the great work.
Regards Tony
Huh, weird... I just wrote an in-depth reply to you directing you towards info and resources that could make the purchase of this machine very possible for someone with a disability. Especially if they have access to veterans related programs and resources as well but.... it got deleted somehow? Maybe because it had web links in it and the spam settings blocked it? I don't have time to rewrite all of it now so I hope the condensed version, without links helps.
Anyway, as a disabled person myself who recently funded a startup on a shoestring by using some of these resources I hope you will at least look into what I post. Having disability is no longer the barrier is used to be. Unless you are physically unable to use that machine there's no reason you can't own it so don't sell yourself short.
I can't go into as much detail as my first post but...
First, reach out to local micro business development centers in your state for help with things like writing a business plan they are normally state run or the state may hire the service out to another agency. If there are none reach out to a nationwide volunteer organization made up of retired business owners / leaders called SCORE (Service Core of Retired Executives) who can set you up with a mentor. Both agencies can can do everything from help you write a business plan to directing you to resources and in some cases funding. That funding may be low interest loans or grants from state, federal or private sources. I was about to find a grant to get me started which reduced the amount of my loan. Second, take advantage of the Vocational Rehabilitation program, they don't just help disabled people find jobs they can also use their resources to help you start a business including with funds if you have a good business plan in place and you can convince them of your idea (up to $2k). Do the same for the Veterans Administration and take advantage of everything they can offer.
I'm sorry my original comment got lost but I tried to post the main gist of what I said in it.
I didn't start up a business to make a fortune, I did it to keep moving and slow the progression of my disability because keeping busy helps. It's the whole "A rolling stone gathers no moss" philosophy. Even if you only make enough to pay back a business loan it would be worth it because it will stop the negative thoughts that fine with feeling there are no options.
Thank you for your service and I hope I have been of some help or inspiration to give it a shot. What have you got to lose?
Hey there. Excellent job. I've been showing my daughter (16) some of your videos. She finds them very interesting. You're very professional and coordinated. This review was excellent, covered all of the points of interest for me, for this product. I will undoubtedly be adding this to my toolbelt in the future.
Thank you so much. I look forward to more content on hardware like this from you.
🤤 that needs to be in my shop...
This is a pretty amazing review and great analytics on the End. Makera should take all 5 suggestions seriously and offer a 20-40W Laser optional on top. Then They got me . Thank You for this review!
As a retired machinist, I can see that this is a very good machine for small work pieces. It does a very good job milling aluminum even at a 1mm depth of cut. There is some chatter in the corners of the slots milled in the aluminum plate at the higher depth of cut. To reduce the chatter, a shorter end mill will do the trick. But having a small work area, it wouldn't be big enough for most of the parts I'd like to make with a CNC milling machine. I have an old manual Bridgeport that I use for my hobbies. It's a great and versatile milling machine, but it's not CNC which greatly reduces the type of parts that can be made on it. Oh well, I'm retired, but I still enjoy the equipment I'm able to afford. Thanks for a wonder review of the capabilities of the Carvera CNC Machine.
Great video, girl, a lot of work! One of the best reviewers on YT. On the funny side, I anticipated that flat nose issue, albeit I never used a CNC machine and I didn't know what model will be cut (but I work in industrial products design and our factory has some large CNC machines too). I couldn't stop laughing when I saw it. I love that you show all the process, and don't censor out the mistakes you make (well, some of them at least 🤪), this is a very good way fot you to teach, and for us to learn from these part-reviews, part-tutorials. Kudos!
27:16, look how far the end mill is extended from the collet, and also notice the flute length/cutting edge of the end mill. After I posted my first reply, I came back to watch this part again. The finish of the first slot is better than the last due to the depth of cut. Even though the end mill is small in diameter and it's extended possibly an inch from the collet, a very good finish could easily be obtained by taking a light climb milling cut of 0.005 thousandths on the edges of the slot. But, a shorter end mill at this diameter is always best for achieving a better finish.
Your reviews are really really good!
As a retired CNC Machinist, I just wish I had the $4K available that isn't already earmarked for needs and not wants. The laser engraver even looks good enough to etch 305 x 305 x 5 mm granite or ceramic tiles with copies of books for SHTF storage and rebuilding our tech knowledge base. If enough sites are created even the morons in charge can't destroy human civilization with a WWIII
Hey Aurora, great vid as always. I was just wondering what you think about the Makera and Snapmaker Artisan. Which one should I get? I'm completely new to CNC and Laser engraving, but i need one to manufacture foam cars for F1 in schools. But it would be nice is it were more capable than just being able to cut foam XD. Anyways, please let me know your opinion on which one is better as, primarily a CNC machine but also a laser cutter. Thanks!
It is a shame that the tools cannot cut a chanel at least 100-120 mm in depth. Then DIY home built jet engine builders could make their own centrifugal compressors in the 200-280 mm diameter
hands down the best reviews on youtube! big thumbs up!
question: if i also want a 3d printer:
snapmaker artisan 3 in 1 or the makera carvera plus a bambulab p1s?
solely for hobby purposes, i can get the artisan for around 2.3k while the carvera and printer combo would come to around 5k
30:07, Look at the radii' at the end of the slots from the first to the last, this is what I call chatter due to a heavy cut with a long, small diameter end mill. Yes, it's not bad looking, but all the slots could look uniform with a light climb milling pass on the edges of the slots..
Great demo of the machine. It would be helpful if there was a mention of the noise level. Will it wake the dead, dog or use it in an apartment?
If there was a bigger spindle I would buy one in a moment even though that 200w spindle did remarkably well.
Holy shit this is amazing. If I had one of these I could make my exoskeleton way less bulky. I'm over here printing parts for custom linear servos out of petg lol. If I could make them out of aluminum they could be so small and still strong af.
hi princess
the egyptian model was cut to perfection.
that particular cut is spiritual and not software.
it has nothing to do with g code.
the nose and ears are missing because it is true of most egyptian artifacts of today
i value that particular cut as exceptional with a high value mark up.
it should really be on display and i hope you did not throw it away.
the sphinx or most egyptian artifacts have their nose missing etc.
i hope you did not throw it away
sincerely

Great video. Oh well in April 2024 the price now is around 5550 USD
Great video. Can you make a video on a home injection molding machine?
Support cutting fluid for metals?
Very versatile but mechanically questionable.
Excellent review. I can tell you put in great effort to make detailed but concise reviews. Subscribed.
what about noise? was it noisy?
It's quiet, and with the enclosure, it's super quiet. It only makes some noise when cutting aluminum aggressively at 0.8mm - 1mm depth.
It is $4800 now. Was that your fault? Hmmm.
Looks nice, but way out of my price range.
Hey thank u for the awesome review. Liked and subbed. A you please tell me if it will be worth and investment for creating art products like bust statues of metal ? What’s the maximum size I can do ?
I don't think this machine can do that, as the 4th-axis is not strong enough to grip the metal for engraving. However, it should work well with wood, resin, and other softer materials.
Thank you for such a thorough and detailed review. As a machinist I am impressed with your knowledge on this machine and G code understanding.
I have this CNC in my future possibilities. This review helps me decide this is #1 on my list!
Hi, Mechanical Engineer here... Working on a 33t 5-Axis with Heidenhain ITNC530 and searching for something as a "toy "at home... My oppinion:
Perfect Video ♥♥♥ Very sympathic lady not giggling or making fun but bringing out facts and knows what we wanna know about, thank you lady, if i wasn´t that far away, i´d like to invite you on a coffee for this video! ♥🙂 Thank you!
Kind regards from Austria
10:18 This corner was high when probed, but deflected downward when milled, reducing depth-of-cut. This deflection is a risk of using a compliant wasteboard without adequate clamping.
Great job as usual!
Please check out the HX-8610 VMC. It’s made in America and is mainly sold to the education sector. Fully enclosed and cuts steel. At a price point of $5700 it’s worth a look. I’d love to see your opinion on it 😁
Hey there. Love the review!!
I am about to buy this machine but have some questions and seeing if you can answer them.
I would like to know the following.
1. Can the 4th axis be used with the laser to etech say thermos or water bottles or even your part.
2. Can the laser etech anodizing or say powder coated or etch brass?
3. Have they gotten back to you on youe upgrade suggestions. You were spot on with those.
Thank you so much agian for the great review.
A very Good Good GOOD review of CNC. Just see the serial model who become but for now, it's very good price for this quality and capabilities.
Thank you for your time and this vidéo ! Kiss from France
What tablet are you using?
Nice to see Millyou breaking out into other type of CNC machines, Next try getting A Tormach Lathe And Mill!😃
What is the collet size? ER-11? What about milling aluminum and brass? I need to make parts for a machine, parts have holes and tap threads, is out possible to do this on the machine?
Will this cut stainless steel?
This is the best review I have seen of this machine! I really like how in depth you went, especially the section on aluminum. This review is what lead me to purchase a carvera. Long time subscriber, you are wise beyond your years, Destined for greatness.
3d printing is cool, but plastic just doesn't cut it sometimes. This is a very cool machine, seems very well made. but out of most hobbyist' price range imo.
Hello there, can you use the 4 axis on soft metals but alumnium or only on wood? Thank you for yhe great review!
I don't think the 4-axis setup can work well with aluminum because the clamps may not be strong enough to grip the metal securely.
Awesome content but the background music is starting to detract, especially around 13:55
This is an excellent review that fills in several holes and provides additional support in "how to" setup our new machines and controllers. Quick note, the link for the CNC vice does not connect to the same vice, is it still available? Thank you!
This was an excellent video. Thank you for running through all of these tests.
thanks but still have a question, as the board is fixed and under the board there is metal,when making drilling for the board, the drilling bit will not broking as it will touch the iron base when drilling the board. thankd
speaking of pcb milling...
I wonder if it can apply solder paste and do some pick and place...
Thanks for pointing me in that direction. 😅. Didn't know this machine is Out there
impressive Maschine.
And ABL in the build too
Great video and walkthrough as always ☺️
thanks for sharing your experience with all of us 👍😀
This a really well done and extremely helpful review. Thanks for taking the time to cover it all!
Wow you’re Awesome and very intelligent young lady 👍🏽
she doing God work.
Amazing Video this channel is under rated
very nice review thank you, i would be interested in this if it came with a little more power all i would want to do is machine aluminum.
Thanks ❤
Boss ass review!
Thanks for doing this great review. I'm sold!
At that price you are getting close to stepcraft prices and are much larger
NICE JOB!
You are very well spoken and do a fantastic job of demonstrating the machine and pointing out there weaknesses as well as their strengths. Well done.
thank you a LOT for this review !
the price is not justifiable for its limitations
$4000... Going to have to give this tech a little more time to get down to a price I can personally afford (sub $2k range). A ton of possibilities though, looks amazing!
It's up to $4800 now, probably because of this review.
Can you all do a review on two trees 450 cnc
the ATC and servo motors a real advantage
Can you use the 4th axis to CNC metal?
Мой лайк #1000
Are you still enjoying this machine? What is the maintenance on it like? Thank you for doing the Al stress testing; none of the other reviews I've found do more than the demo parts included with the machine... which have undoubtedly been optimized for the machine.
Yes, I like this machine so much, this is the only CNC machine on my recommendation list, please check out my website at auroratechchannel.com
great in depth review. One of the best I've seen so far 👍
Would love to own a CNC machine like that, but sadly it’s way out of my budget range 😢😢
The price has even gone up $800 since this video.
now u getting into CNC!! Nice!
wow, super detailed review.
Is there a budget table cnc that can mill hard metals and accepts cam software?
I think only the Nomad 3 comes close, what do you think?
Thank you for taking the time to make this review, I found it very informative and helpful. Do you know what size tablet the Makea Carvera tablet holder accommodate? Also which Widows tablet did you get for it?
I am using an old Dell Latitude 7275, which has a 12" screen size. I purchased it from eBay for approximately $150. I believe 12" is the largest size it can hold.
@@AuroraTechthank you
Great review!
that is cool
Is there any chance you could make a video review on the Laserpecker 4? I’m curious to hear what your view is and think you provide great content would be much appreciated!
Yes, the Laserpecker 4 was supposed to review by the end of Feb, but I didn't receive the machine from them yet and may need to postpone it.
Some of my questions I had concerning the Laserpecker 4 and company Im general is how well there customer service is, how well their app works and if it’s conveniently compatible with iPhone. I’ve been considering buying one and hesitant whether it’s worth it starting up a small side hustle business. Maybe I should go for one of the bigger co2 lasers, would be nice if you could do a video on which of those are best overall also! Really appreciate the aspects and content you deliver to your page!
👍🖒👍@Aurora
❤ love this machine
Great
Great review
Awesome...
Bed size for a CNC is way too small.
For a router, yes. For a mill, it's pretty generous. For a general maker tool for PCBs, and components for desktop projects, I think they've got it about right. I use a homemade CNC router and am currently investigating adding an auto-tool-changer, but it's definitely not easy, so kudos to Makera for delivering all this in a prebuilt machine.
What is the windows tablet and tablet mount?
The tablet was a used Dell 7275 tablet (i7-M/8G RAM/256SSD) I bought from ebay for around $130. The mount came with the machine.
Thanks for the fast reply. Would you recommend this as the best all around CNC mill for beginners?
Awesome video demonstrating this machines capability! Thank you.
Hello great video im a long time subscriber. Im a tool and die maker and Manufacturing engineer in California. You guy do such a good job and i regularly learn from your videos. Like always great content and i wish u luck on the success of the channel
Hello! I just wanted to give you a heads up that you put this video into the lager engraver playlist, in case you want to move it to the desktop CNC playlist.
Have a great day!
Is it you or TH-cam who keeps deleting my comment? 😜👍🏻👍🏻
I guess it was TH-cam, I won't delete comments unless for those spam posted by bots.
@@AuroraTech Maybe they see my thumbs up emojis as spam or something I dunno.
This is worrying - I also posted a comment yesterday and I can't see it (it was about the Makerdreams Evo One Pro CNC being another machine in this price/capability range and worth reviewing). Aurora, perhaps you could suggest another way of sending feedback that is more reliable?
Really enjoying your reviews 👍
