Building a (modified) Mostly Printed CNC (MPCNC) Part 2

[@robashley2860]

The spindle bit at the start had me in tears!!! Thanks!

[@klschofield71]

Always satisfying to get those first chips. Great job on the build, modifications, and sharing your journey.

[@guilhem1369]

4:20 min -> the marks that are mades came from the way you are working ; if you look closely, you will see that when it’s working left to right there isn’t any problem. However in the other side, marks are made It’s caused by the way your bit is turning (I don’t know how to say it in English but in French it’s called “travail en avalant ou en repoussant”) the good way to work with a CNC to have a perfect result is by working “en avalant” If your bit is turning counterclockwise, the part of the bit that should be in contact with material is the left part for exemple

[@leonbrauns]

I think you are talking about climb and conventional milling. It actually created a ridge in both directions. The lightning and camera angle hides the other one quite well, but I could definitely see and feel it while filming. Thanks for your input nonetheless, going to make sure that I am always working "en avalant" ;).

[@lewtgoblin8437]

yup, thats what he ment, but the problem is the width of cut as i see it, you coud double the feedrate at least and never take a wider cut than half of ure bitsize, but i just run easy matarials like MDF,lexan,macrolon,plexi and sometimes soft metals like aluminium or brass / copper

[@lewtgoblin8437]

sry, i also have a 60 K rpm spindle... makes a big difference...

[@JavierChiappa]

Most helpful CNC machinist comment award, goes to this guy.

[@lezorn]

The kind of humor reminds me of this old Tony.

[@PiefacePete46]

Your apology was not necessary... we would be very disappointed if you did not show us this essential part of the build! It's the part where you get the "warm fuzzies" as payback for your hours of work. Great videos thanks, liked and subscribed.

[@TheLeverHunter]

Wow that looks awsome. I like the threaded inserts you used, I will definitely be incorporating those into my plans. Great Job!

[@RoamingAdhocrat]

Fantastic stuff. I have a GearBest T8 engraver, with limit switches made of microswitches epoxied onto the frame - took forever, half the time I glued the switch shut, and one of them since fell off. Envious of your much more sensible ones!

[@kaushikprakashrobotics]

Really nice job with this! It is very satisfying to watch. Great job!

[@SandwichMitGurke]

you have a lot of potential man

[@marklowe7431]

What i find most impressive is although these are sort of home made kits the engineering is amazing.

[@yakine13]

wow amazing quality that incredible!! you have the best homemade cnc ever!

[@obe22099]

Super informative! I wanted to be able to prototype with 3d prints and replace them with aluminum. What was the price overall estimate not including any 3d printed components?

[@mohieali7317]

Great work, wonderful engineering design and logical thinking

[@magnushacker5203]

I am thinking of buying exactly that spindle. Is it noisy? (it's not brushless, is it?)

[@allted]

Great video!!!

[@fredpinczuk7352]

Best compliment anyone can ever get from the original designer!

[@abarasabwehttam]

I am building a couple of these right now with my Adv Man high school class. They are great projects. I like some of the mods vs just the original files. I will need to look up the models and add them to our builds.

Subscribed! Brilliant. What were your Design Goals and Compromises? Thx.

[@moth.monster]

The magic of video editing...

[@frederikdesaulniers9699]

Hello. I like the double belt upgrade! How do you call that tape you used on the spindle clamp at 1:00?

[@leonbrauns]

That is foam tape.

[@leonbricks8454]

What's the name of the spindle and Can you cut aluminum with it

[@preciousplasticph]

you actually should turn up your feed rates. that foam will cut as fast as you can run the machine and the wood cutting you can run 2 to 3 times faster

[@mohamedhossen9348]

I was alittle confused with the spindle 😂😂

[@ADRIELSS1]

Hello, congratulations on your project, it was very good. What is your cnc router controller card, drivers and motors?

[@ciscokid925]

Hi great job on your build. I have a question about the specs of your build. What controller bird did you use? Do you know what the differences are between the SKR pro and the Rambo?

[@PracticalRenaissance]

Very impressive work!!

[@lgtwzrd]

You should 3d print a vacuum hose tip that stays close to the drill. Just an idea.

[@massilamany]

Really a nice video. Great work. I like it. Thanks for sharing.

[@fhuber7507]

The use of a handheld shop vac shows that you should mount a vac system to the cutting head.

[@AndrewHelgeCox]

The cutting of polystyrene board made me wonder: could that be useful. CNC board, apply resin and glass fibres, apply beauty resin coat. Maybe that would be light and strong.

[@benh8core212]

HEy Brauns CNC Saugeile videos =) Würdest Du vielleicht noch für schwere Spindeln zb ne 3kw Wassergekühlte eine Doppelrohr Version machen und mir/uns die F Version zur Verfügung stellen ? Das wäre Top !! Grüße aus Unterfranken

[@darkshadowsx5949]

its looking good. i recently tried making wooden props for display but my flipping method was flawed. my mpcnc didn't like milling a pine 2x4 it would start chattering in the dark grain and eventually ruined the project..

[@dukeofficial2457]

Moin geiles Ding darf man Frage wo du deine Fräser kaufst?

[@tomcypher3864]

For cutting foam you might need a quadruple belt!

[@tonyrebeiro]

Great video. Thanks. But just one small suggestion. Please try to keep the background music level, below the level of your voice, so that we don't have to keep fiddling with the volume control, whenever the music comes in.

[@realsoftgames7174]

i was honestly thinking about doing this but how are the 3D printed parts holding up and what about that milling motor is there another version you would pick that is more stable for example mounting it more directly with nuts and bolts rather than heaving it tied down with plastic parts, over time they would break?

[@leonbrauns]

So far no plastic part has failed. Also the spindle mounting brackets are plenty stiff and work very well together with the spindle.

[@realsoftgames7174]

@@leonbrauns thats great to hear. i was looking at building one actually and wanted to know if it was worth doing. i plan on doing mostly aluminium. any advice on what you would change to make that work better? i was looking at a large build area.

[@leonbrauns]

If you don’t have any experience with CNC machines the MPCNC is a great starting point. It definitely can cut aluminum, but it will take some time. Also you want to have a work area as small as possible for increased rigidity.

[@omarcastanedalara1856]

What software do you use to work the team and recognize what you want to do in it? greetings excellent project.

[@DjAlanBarratt]

You've probably learnt thus already but always best to move the spindle into open space fir tool changing

[@moritzheinl8449]

Wich Board do you use to controll your MPCNC ?

[@kramerdesign9443]

That intro!!

[@vasilyivanov3222]

Do you use "Dual endStop" or "old" diagram for connecting stepper motors? "Dual EndStop" means that every stepper driver manages only one stepper motor, "Old" - every stepper driver manages two motors.

[@LanceThumping]

Not a giant fan of the limit switches attach method because I'd worry they could slide slightly on the rail and mess with the dimensions of the work area.

[@pyramidsinegypt]

Recently got an Ender 3, finally got it dialed in, so eager to start printing parts for an MPCNC after seeing your build! Out of curiosity (and to not break any endmills), what RPM, Feed Rate and depth of cut were you using to mill the wood?

[@leonbrauns]

I don‘t know the feeds and speeds I used in this video anymore, but milling wood is fairly easy. Start with something like 20000rpm, 600mm/min and a small depth of cut and work your way up.

[@JordanNiks]

This is Unbelievable! Was wondering if the STL's are available for the Modified parts you used?

[@leonbrauns]

Check out the description.

[@marcokohn5762]

which controller board and software you are using?

[@CiaranWhelan]

Fantastic video watching those first chips. And the music was definitely fitting to the video. Some videos use the music that is way too loud or massively not appealing to a vast majority, however you chose some good middle of the road music for most. Can I ask for a link please to the plugs you added to the top of each stepper motor please.

[@leonbrauns]

Just search for "SM2.54" on your favorite shopping site (aliexpress, ebay...).

[@CiaranWhelan]

Brauns CNC awesome. Ideally what I'd love to find are ones that have screw ends on the plugs. Have you seen the ones on Openbuilds? openbuildspartstore.com/xtension-connectors/

[@leonbrauns]

I haven't seen those before. However I would prefer crimped connectors. There are many different types available so you can choose them depending on your application and they are a lot cheaper.

[@Anonymouspock]

@@CiaranWhelan Crimps are a hell of a lot better than stranded wire in a screw terminal. If we're going full belt-and-suspenders, the wires would have ferrules crimped on them before being put in the screw terminals so they don't come out as easily and make better contact. Ultimately both ways you're crimping stuff and the more robust and more compact way is crimp only.

[@mastercat]

how much time it takes to print all the parts and wich material????...awesome

[@BOOMHeadshot1006]

How well does this platform work on hardwoods? Oak or Maple for example?

[@marcovasco8619]

Hallo. Würdest du diese CNC noch einmal bauen und verkaufen?😄 finde es echt interessant, aber würde mich selbst nicht da ran trauen sie zu bauen

[@Stufffredlikes]

Just a quick tip, when cutting wood or anything really try and cut in a conventional direction so the bit doesn't try to 'skip' along

[@runforitman]

alfred spiteri hili what do you mean by “a conventional direction”?

[@Stufffredlikes]

@@runforitman basically imagine its cutting clockwise looking from above. You want the good edge to be on the left side of the direction you are traveling so the blades cut well. If its on the right side then the bit will want to skip along because the blades are pushing in the same direction you are. If you are cutting a channel and theres wood on both sides, cut in the direction that puts the good side on the left. So basically anticlockwise around outside curves and clockwise on inside curves. (Assuming bit is rotating clockwise ftom above)

[@NoFlyGuy_Actual]

That's funny, I did "Hello World" for my first cut as well when I finished my mpcnc.

[@Tertion]

Ok....I need to build one now.

CNC polystyrene fast with deep cuts. Pour concrete into the mould you just made. Cure. De-mould.

[@flomuc5665]

Great video, great focus on differences to other approaches. Your modifications are very interesting, a solid foundation for increased precision. May I ask a question on the stainless steel tubes - do you use constuction or precision type tubes? Some MPCNC makers are reporting on issues with diameter tolerance using the chaeper (~8€/m) consturction tubes. What's your experience/recommendation?

[@leonbrauns]

According to the price, it seems I am using the construction tube. I haven’t had any problems with them.

[@kevin_delaney]

Please learn more about Fusion 360 and about CNC machining in general, I do not wish to discourage you in any way. This is a whole hell of a lot better than my first CNC machined part. Look into Lars Christensen who is a Design & Manufacturing Expert, Titans of CNC because Titan owns his own Job Shop and runs sick speeds and feeds but offers a few Academy online to learn, and maybe TFI CAD Tips (which is Autodesk Inventor focused but great for CAD). Just....improve work holding, always climb mill, and learn about chip per tooth milling. Use high feed rates and shallower cuts and you speed up machining so much. I look forward to seeing some of your future videos, stay safe.

[@Duraltia]

First order of operation: A Dust Shoe ( imgur.com/a/64PLvHl ) Btw... @05:30 You may want to enable _Both Ways_ in *F360* when doing 2D Adaptive... Saves time and if you're concerned about surface finish I'd recommend leaving 0.25mm material at the sides and the bottom and finish with a regular 2D Pocket but then with zero Stock left which - IMHO - produces a nicer pattern in the material
