More Aluminum Cutting on the Mostly Printed CNC

[@muggzzzzz]

I never thought that MPCNC is capable of cutting aluminum with that finish and THAT precision! You have my respect and an instant sub, sir!

[@nexgen91]

I know right, this makes me want to put my MPCNC back together (though I think I will need to do some upgrades ie: looks like OP has larger belts, and possibly bigger steppers than I used).

[@JasperTielen]

Thanks for providing all settings, this is one of the most helpful videos I've seen so far.

[@hed420]

Ok, I'm impressed .

[@darkshadowsx5949]

nice Johnny bravo hair.

[@Mitokafander]

Finally someone giving actual feeds and speeds instead of some "it all depends on several factors" bs I read all the time.

[@joetke]

Each time I watch your videos I can't help admiring your MPCNC, a great achievement indeed. Amazing that a relatively "cheap" built-from-scratch CNC meets such level of precision... left me speechless. Thank you!

[@modern_DIY]

This has inspired me to stop watching videos tonight and get back to work on my 1/2 finished MPCNC.

[@SuperYellowsubmarin]

True story

[@matts.8342]

Same here. Mine is assembled and I have cut foam with it, time to move up to some wood!

[@brandonsmoot4056]

Did you finish it?

[@modern_DIY]

@@brandonsmoot4056 Actually, I did. Cut some wood and plexi and made a clock. Then, wanting to cut aluminum, I started to add a compressed air/dust collection system but life intervened and I didn’t get back to it for months. Coincident with your comment, I just finished the new hardware last night and it seems to work. The air blows and the vacuum sucks, at least. However, to really test it I need to relearn the software because it’s been months since I touched that side of things. Hopefully, I’ll be cutting again soon (and fight the urge to rebuild the whole thing with the new primo parts).

[@brandonsmoot4056]

@@modern_DIY what air blast system did you use? I'm working on mine myself

[@BrianLeeWho]

Very, very impressive, and the finish is also very good. That is one amazing MPCNC.

[@agilecreator1687]

Für mich als Anfänger, habe gerade mit dem Bau der MPCNC begonnen, ist das was Du hier zeigst beeindruckend und Hilfreich. Danke dafür, Abo hast Du

[@AndrewAHayes]

What you need now is a furnace to cast all that swarf into new parts or blanks

[@imqqmi]

Reminds of my first 3d printer, a prusa clone, a wooden frame of 6mm plywood. After many months of tweaking I got a single perfect print. Then it got out of alignment again and gave up. Got a corexy now of my own design and without much tweaking just prints excellent prints every time. You must've spent many days adjusting and experimenting to get it to this level, better than my ox cnc build. That has now been replaced with a much more rigid design of my own using linear rails bought from aliexpress with some reinforcements here and there, with 20mm thick aluminium tooling plates and steel tubing. Incredible results anyway you slice it!

[@warwickwoodshop8358]

Awesome, the final push I needed to actually try and build one of these. Subscribed 👍

[@byungjaelee5110]

Wow this cuts like butter... can't believe how easy this performs without any problem.

[@chuvvyyk]

my god... but how? what? very impressive! thank you for sharing your experience with us!

[@design8studio]

Cool! Excellent info. I really appreciate the specs and details!

[@FilmFactry]

Can you link the endmills you used? Aliexpress? I really need this ability. Excellent video!!

[@geekoid183]

Also interested.

[@leonbrauns]

I have tried several different end mills from aliexpress and didn't noticed any difference. Just search for "single flute carbide end mill 6mm" and go with the cheapest one.

[@OperationAllOut]

@@leonbrauns so single flute does that nice cutting and finish ? What's the feed and rpm ?

[@AlanHerrigCreations]

@@OperationAllOut man, just watch the video

[@OperationAllOut]

@@AlanHerrigCreations ya got it bro, just commented early ..

[@jrmichel1975]

You can also use tabs to keep your part in place at the end of your cut. Of course, it will require some manual finishing of your part...

[@darkshadowsx5949]

how did you get rid of spindle deflection? its almost like i printed mine with ninja flex instead of PLA.

[@Matt-wb7lm]

Many have said it already, but very impressive. Keep the vids. coming. Very enjoyable.

[@mrbritcoinnakamoto2793]

id love to see you do a video on the software you designed this program on as im having a right head ache would be insightful thanks

[@RinksRides]

That is good accuracy for 6mm belts and NEMA17's. I happen to have at least a dozen of older NEMA 17's I bought from ebay quite a while ago, maybe I can finally put them to use on a lowrider 2 version I'm designing. I like the concept, but I see room for immediate improvement.

[@AlanHerrigCreations]

Excelent, thanks for your tips, sooner i will build my own, your information really gonna help me.

[@christophergrove4876]

I very much appreciate this. Nice knowing just how far one can push the MPCNC.

[@jmtx.]

Thanks for sharing your awesome results!

[@AmauryJacquot]

you can also use small tabs at the bottom to keep your part attached to the rest of the stock, and cut it later

[@stollifpv3322]

Amazing video.🔥 What spindle are you using?

[@J1I9M7M4Y]

Amazing result for this kind of router. Very god job there!

[@tommyers7634]

An often overlooked measurement that can affect your CAM accuracy is the diameter of the bit(s) being used. If the actual diameter is different (usually smaller) than the nominal diameter, using the nominal introduces inaccuracies into your CAM.

[@misteragb7558]

Did you ditch the upgrades? where is the double belt setup?

[@andrewpepmeier268]

Where did you get the files and what spindle are you using? I’d love to be able to do this but not sure where to start

[@petervier]

any recommendations for cheap endmills to cut plywood?

[@ChrisHarmon1]

Didn't you have videos showing angle iron upgrades on your MPCNC?

[@jasonlipavsky7371]

I like the tube wipers to keep the chips out of the bearings

[@brocharumplestilskin4513]

You mentioned a Chinese brand. The flute section seems long on yours can you list the single flute bit so we can find it. thanks. I found a ton of them but hesitant as they tend to break easily. Great video!

[@shanemcdoogle1662]

Is there a reason everyone recommends single flute bits for the MPCNC? I haven’t had many problems with 2 or 3 flutes, so I’m just wondering if I’m missing something… This video is great btw!

[@wonderfalls2]

I've heard other people say chip evacuation is difficult. I think it has to do with having to run at a high RPM because most of the cheap spindles don't have great torque at lower RPMs.

[@jeremya8844]

Amazing ! What are the dimensions of the CNC ?

[@leonbrauns]

Work area is roughly 600x300x50mm.

[@geekheretic]

Do the collars you have around you axis reduce slop? At 3:03 you have a closeup on one of your axis's and it has a supplemental black bit. I ask because I just cant seem to get rid of my center gantry slop

[@leonbrauns]

Those are wipers to keep the chips away from the bearings.

[@PiSSPiSS2020]

I couldn’t find it mentioned in your build series, but what is the build size? Thanks!

[@ciscokid925]

Do you have a video on your air hose set up? If not can you please post that Info. Thanks.

[@captivenut4122]

Great results! One question though. I remember an older video where you modified your MPCNC. Those modifications don't seem to be present here. Am I missing something or did you not end up keeping them for some reason?

[@nielssamuels5465]

Was curious about that too. He had the dual reverse belt setup.

[@leonbrauns]

I published an update on thingiverse as well as on the v1engineering forum about that: The glued belt started to curl up. Instead of fixing it I took the chance and switched to a single belt. As I didn't notice any difference, except that it's easier to set the right belt tenison, I am keeping it.

[@nielssamuels5465]

[@tgirard123]

I'm so sorry to ask, at 4:30 Your talking about doing a Helical cut and you say something at the end, "I'm just not able to avoid some..." Was that "Shadow" Cuts or "Shallow" Cuts? I just really want to be sure I understand what you were talking about here because The whole Helical cuts setup is still a little confusing for me. Thanks :)

[@curtislitchfield1378]

Would love to understand why you don't use the dual belt system anymore on your MPCNC. I'm building my own soon and was thinking of using your mods. Why did you remove them? ( I see you kept the 15mm belt though, seems like a good idea)

Is there anything that makes your mpcnc so capable compared to some other ones? I saw your build video but it does look like you are using your double belt system so I don't know what it is.

[@shyowl3453]

for me the reason im looking at a mpcnc is I dont really have a reliable way to cut metal and id like the additional capabilities that a cnc offers for woodworking as im not artistic in anyway so using a computer and a machine to turn wood into a design is a amazing option for me

There are some modifications to the original MPCNC like a different foot design or 9mm GT2 belts instead of 6mm. I guess using a high quality spindle also makes a huge difference.
