More Aluminum Cutting on the Mostly Printed CNC

Making some big chips and talking about my experience of cutting aluminum on the MPCNC.

[@hed420]

Ok, I'm impressed .

[@darkshadowsx5949]

nice Johnny bravo hair.

[@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).

[@Mitokafander]

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

[@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

[@JasperTielen]

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

[@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!

[@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

[@BrianLeeWho]

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

[@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!

[@warwickwoodshop8358]

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

[@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!

[@AndrewAHayes]

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

[@design8studio]

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

[@christophergrove4876]

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

[@Matt-wb7lm]

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

[@AlanHerrigCreations]

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

[@J1I9M7M4Y]

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

[@jmtx.]

Thanks for sharing your awesome results!

[@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...

[@createforcuriosity225]

Woooooow ! Now I want to test it on my 3d printed cnc...

[@jrmichel1975]

Same! Just finished my upgrade to Nema 23 too! :-D

[@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.

[@jeoq8566]

It's Amazing what you Can Do with ! Respect !! I learn many things from your vidéo !! Thank you

[@seancollins5769]

Wait, this is REAL TIME??? I thought it was sped up!

[@lawrencedavidson5550]

Honestly when I read the title i was no way this can be.. And now.. .that is insane.. how are you getting the rigidity to do that depth of cut? Plus hats off to your feeds and speeds.. they must be spot on.

[@TheLimalha]

FINISHING LOOKS NICE FOR SUCH KIND OF MACHINE !!!!

[@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.

[@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

[@eddietowers5595]

Wow, awesome CNC mill! You have enough aluminum wool to make a sweater. 1 dislike at this point? Must be Sarah Connor wanting to stop all automated machines before they become sentient. Awesome video.

[@brukernavnfettsjit]

That is seriously impressive!

[@yongliangqin8673]

That's some very good mechanical engineering.

[@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

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

[@stollifpv3322]

Amazing video.🔥 What spindle are you using?

[@tharris1291]

thanks best vid so far on this topic!

[@darkshadowsx5949]

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

[@douro20]

It does help that he is using a good dedicated router spindle from AMB-Elektrik.

[@MarinusMakesStuff]

Awesome video, good info. The only thing I'm really curious about now is what kind of projects you're making! :)

[@TheModShopCO]

Very impressive. Thanks for sharing!

[@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

[@bastelmichl4241]

👌 Ich habe ja selber eine MPCNC gebaut mit vielen vielen Erweiterungen und Änderungen genauso ähnlich wie Deine Optimierungen. Ich hoffe es kommen noch ein paar Videoa vom Fräsen mit der Mostly. Mein Abo hast Du schon lange. Viele Grüße von Michael (vom Kanal BASTEL MICHL) 👍

[@aspmos]

I read on the comments that you removed the 15mm belt on an angled iron. Right now I am confused on what I am seeing.I WOULD LIKE TO SEE A VIDEO SUMMING UP what you have made with this MPCNC.

[@enginsula4649]

Great tool btw. Congrats!

[@kielerkarl]

Krass was du so raus knallst mit dem Teil! Echt beeindruckend. Sogar Tom hat ja direkt aufgegeben.

[@fredator88]

[@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!

[@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

[@wanradzduanman1253]

Good job👍👍👍

[@ronreynolds5580]

WOW!!! JUST WOW!!

[@misteragb7558]

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

[@gloriamoreno7501]

Interesante este video me gusto mucho muy importante saver lo que hacen Saludos cordiales para ti Dios te bendiga siempre por compartir este canal muchos Exitos

[@AndyHeisz]

beautiful chips

[@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

[@Renaldo015]

It's probably using high quality filament and stainless tube.

[@rogue277]

Damn bro, your machine is kicking so much ass. I'm amazed what you can do with a machine that has PLASTIC parts for some of the frame.

[@О.Ш-ь1щ]

as for the surface quality it's not the best thing, but as for chips and sounds - it looks pretty healthy, for just 1 part per week it's more than enough. But after I had an experience with cnc6040 and then tried something with steel frame, mgn rails and steel table all this stuff that cuts less than 2mm deep with feedrate less than 100mm/sec for me is just aluminum scratcher but not a cutter

[@petervier]

any recommendations for cheap endmills to cut plywood?

[@josephlabranche4889]

I only do milling by hand have not learned any gcode, but this is bad ass

[@josephlabranche4889]

@sammy Thank you for the info

[@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)

[@ciscokid925]

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

[@3discnc424]

its all about the spindel and the endmill :)

[@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]

@@leonbrauns ah I see. Thanks man. Great vids btw! Keep it up!

Can you do a video on how you did your set up in Fusion? I have been struggling with mine.

[@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.

[@ChrisHarmon1]

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

Is there a project page or building details page?

[@radziecki3166]

How is this block of aluminium held in place?

[@ugkliegis2319]

You seem to use something beefier than the usual GT2 timing belts. Care to lose a few words about that, or a link if you described that somewhere else already? Your setup seems to be exceptionally sturdy and stable. Any special tricks you might want to share? Thanks in advance!

[@leonbrauns]

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.

[@michaelanderson4214]

Great work, my compliments ! How do you release the part from the waste-board, since you use double side tape.

Sau cool, ehrlich dein Video hat mich dazu inspiriert, mich auch zum Bau einer MPCNC durchzuringen. 😀 Welche Maße hat denn deine MPCNC? Ich möchte meine auch lieber etwas kleiner, dafür aber verwindungssteifer und präziser bauen. Deine Abmessungen sehen mir nach einem guten Kompromiss aus.

[@Th3Star4c3]

Mal wieder super Video. Was hast du für ein Ausblassystem ? Suche auch was, was mich an diese Standard Schnellkuplung eines Kompressors anschließen kann. Hast du da ein Tipp für mich ? Vg

[@jgtools]

What your use to fixture aluminum plate in BED ?, congrats, nice jobs!

[@rklauco]

Wouldn't vacuum cleaner work better than blowing air on the spindle? Nice work, btw.

[@leonbrauns]

An air blast is much more powerful which is especially important with deep slotting passes.

[@benh8core212]
