- I wanted to build a CNC Router for a while now and finally decided to go with the Mostly Printed CNC (MPCNC). I added some features to the original version which this video is mostly about.

Love German engineering, people who share their knowledge to help others and people who speak a second language. Very appreciated.
Double belt... genius. Pure genius. I'm totally going to steal this idea!
IKR
The dual belt system is pretty smart. Thanks for sharing it.
Brilliant, neat and professional. Thanks for sharing. One tip: when shortening stepper motor etc cables.... always leave some room for error or future changes.
For those wanting to make an MPCNC, I have saved many hours by not printing all the corner joiners and leg ends.
I've done similar to box in the cnc.
I love what you have done with putting the plugs at the top of each stepper. I've also gone down the path of shielded wires.

Those cam belt adjusters are a fantastic addition!
Dat Moment wenn man nach 2 Wörtern die Hand dafür ins Feuer legen würde, dass der Uploader Deutscher ist.
Deglisch
Jeder braucht halt so seine Erfolgsmomente.
ICh finde man versteht ihn gut. Hab schon schlimmeres Denglisch gehört. IMmerhin korrekte Grammatik und rel. flüssig, was will man mehr?
Ein Deutscher würde niemals die Kabel eines neuen Schrittmotors auf 2cm abschneiden nur um einen hübschen Stecker an diesem festzukleben.
Warum nicht? Macht doch Sinn das steckbar zu machen. ICh würde nur keinen Heißkleber nehmen sondern Epoxy das wird nicht weich.
FYI, 1st version of the MPCNC I used PLA for all (as you show). They nearly all failed with 6-9 months. All cracked or fractured. And they all have been replaced with PETG and ABS parts (zero failures). Hope you have different results.
What % of infill did you use, or do these parts get printed solid?
mine haven't failed yet and im going on 4months. i cant print with abs its too difficult.
I had followed the recommended guideline as posted here. www.v1engineering.com/blog/parts/ Now cranted, some of these parts were on their 1st revisions and some have been re-designed. However, the only original PLA parts I have now are the feet.
I think that a router like that is great as a stepping stone to make the aluminium parts for a better router, so the plastic reliability isn't that big of a deal.
@@darkshadowsx5949 try the PETG from ''das filament'', it's much easier to print :)
Very nice build! The one thing I would be careful about is the hot glue on the motors. My motors tend to get very hot under load, and I wouldn't be surprised if it softened the glue. Otherwise an excellent build! Belt tensioners are quite clever
At first I thought BraunCNC was going overboard with this but I followed V1 engineerings directions and learned the hard way that if you want any mechanical reliability, it is better follow BraunCNC's methods. Of course with permission from BraunCNC.
Very original and excellent solution for the belt.
Really love your mods. I watched a video some time back (sorry, don't have link) demonstrating a high-speed linear actuator using this dual belt system. I tucked the idea away for future use. You have proved it is a really viable system. Thanks very much, looking forward to more videos. Liked & subscribed.
Great video, love the detail of the double belt and the wiring, so clean!
Gute Idee mit dem breitem Riemen und dem Exzenter. 👍🏻
can you post the stl files and a written guide for the modifications? some of the parts were hard to follow, but great video overall!
Thanks
Careful, Ryan will come and tell ya it's a derivative part, and he's cry like a baby till you change it.
Excellent built and techniques.
Was wondering the size you made your MPCNC? And why? Looks like it is roughly 3 x 2 feet? Was wondering how high you made it? Thx and great video! Keep up the great work!
You made a rack gear by gluing the GT belt to the square tube, to minimize belt strech problem further - use direct drive
stepper with GT gear/pully direct on rack
Need more modifications on the original design but may be worth the time/effort.
guy you are fucking nuts, these are some golden videos you got there
your editing is top notch.
But it sounds like your talking with a sleeping child right next to you. wispier quiet and sometimes unclear. try talking with more authority.
good idea with the stepper connectors. i just took mine apart and rewired them with shielded cable. unnecessary to be shielded but it was cheap. I needed longer wires and didn't want to splice them.
Thanks, I am going to keep this in mind.
haha lol i had similar thoughts, lol try this quick fix :

I very much like your work. That said, English (my native tongue) is very tricky. Please speak up. Your words are worth hearing! :)
Benjamin Patrick as a german: no. english is far from being "tricky".
@@FrustratedBaboon Constructive criticism isn't complaining.
I like your corner caps! I'm going to seek them out and replace mine. So much sleeker looking. Your entire build is top notch my friend, as is your video. You got yourself a new sub and smash of the bell button.
Wow, man! This is definitely the most professional and sexy looking CNC I've seen so far!
Great technique and skills
You could use a loop belt attached to the stepper using this approach, I like it!
Awesome! Great stuff and awesome work!
I just started printing and hope to get similar good results as you did.
Hope to see more from you! (especially working with Aluminium on the MPCNC)
Mach bitte weiter so! :)
Wow very impressive The quality of your product is Very good.
I love this and I love you for sharing
I really like your modified version of the MPCNC.
Can you please tell me what spindle you used to get such amazing results with aluminium?
I am using a "FME-P 1050" by AMB
👌 Hallo Leon, sehr gut Deine MPCNC und den zahlreichen Veränderungen zum Original. Das mit den Doppel Kugellagern und breiteren Riemen hätte mich auch gereizt, jedoch sind die "normalen GT2" Riemen ausreichend für Nema17.
Ich selber habe auch eine MPCNC gebaut mit vielen Abweichungen zum Original. Den gesamten Bau dokumentiere ich gerade auf meinem UA-cam Kanal BASTEL MICHL in einem Mehrteiler bis ins kleinste Detail, inklusive einer gedämmten Einhausung mit Doppel Verglasung.
Wer Interesse hat sich den Bau anzuschauen, ist gern auf meinem Kanal eingeladen.
Viele Grüße von Michael (BASTEL MICHL) 👍
very professional project
@5:14 what is that wire connector crimping tool called? I do it with another kind but it takes me so long to do each one.
Thanks for sharing your ideas, they are really cool..
Could do with the GCODE you created for calibration.
Saulgeil! Ich bin gespannt auf weitere Videos!
...Step motors is hoted for longer woork. And glued conectos will be droped...
"hoted" ?
The stepper motors might get hot and could melt the hot-glue
If they get hot something obviously wrong.... mine are always cool even for my 3d printer when it was running for 12hrs a day to print parts for the mpcnc. the motors for that are always cool too. you cant really drive it super fast when milling either.
Most steppers are rated to a very high temperature. They can very well get to 70°C and higher under continous heavy load. The gantry of a CNC is much heavier and the material beeing milled also adds up to the load, you really can't compare that with a 3D printer. I agree that if they get that hot, there is probabbly an operating mistake, but it's one a beginner is likely to make: a bit too much Z increment, a little too high feed rate, unfamiliar material... You might end up with a heavier load that the machine could handle otherwise. Also that's not a problem you'd notice right away, the heat would slowly creep up.
Better safe than sorry I'd say, a bit of epoxy or silicon would be a better choice
I do agree epoxy would be better. I just spent about 3-4 hours milling a pine 2x4 which my mpcnc seems to hate and the motors are still room temp.
tight grain hard wood actually cuts easier than pine. when it gets into the darker portions of pine it chatters and vibrates. sometime its enough to grab or throw the spindle out of position ruining your work.
Id say its more of a bad stepper driver issue than anything else that would heat them up. like setting the driver amps too high for the stepper. the driver will definitely heat up and the over current to the stepper will cause it to do the same. I have 2A steppers with the drivers set to run at 80% of that.
besides the MPCNC isn't really a good CNC platform i found a more traditional style cnc with 3d printed parts on YT that looks much more stable than this one.
I'm considering rebuilding it and/or the newer one i found. its on Leon van den Beukel channel "Homemade CNC with 3D printed parts". check it out if you'd like.
Great idea with the belts.
Which Controller are you using. I am looking to have 5 drivers, one for each motor. Could not find any so far.
Looks great and you have great design skills and video editing skills. But maybe consider linear bearings (12mm) for all axis movements this would ease the design and reduce the part number.
Braun, thanks for sharing your thoughts on this video. I noticed you are using a double-belt design. In the USA, this design has a patent pending by Bell-Evermann. Of course, hobbyists may construct the design for themselves but not for sale. The reduced exposed belt length makes a huge difference in rigidity.
There is also another similar design that might interest you. The upper belt can be a small continuous belt that is double-sided. The inside teeth wrap around the motor and pulleys, and the outer teeth mesh with the lower belt.
Nice video!
Thanks for the comment!
Brauns CNC, will you be sharing your parts designs as well?
He already did: www.thingiverse.com/thing:3101774
You have to crapping me. Someone is trying to patent the idea of using 2 belts? Good luck with that.
There is NO 'patent pending' on this design. The patent application by Bell-Everman (US20090301237, filed in 2008) was rejected and subsequently abandoned because the idea was not new.
Already in 1979 German company Hamuel Werkzeugfabrik described this idea in their patent application DE2910373 which has lapsed long ago. It was also disclosed in e.g. DE3935690 (1989), JPH08121558 (1994), JP2000229717 (1999) and many more.
Can the MPCNC work properly with a 30" (800mm) work area and 5" on Z height? Always hard to tell how large these machine are in the videos.
The work area of my MPCNC is roughly 600x300x50mm. Especially a big z height will decrease its rigidity. If you want a big machine, check out the Lowrider CNC.
I would be happy to have an ABO back.
I wonder if your belt drive mod would make a better type of cartesian 3D printer. The ghosting artefacts from a heavy bed on a stretchy Y belt would be reduced.
Fantastic
What PLA did you use for the red parts in this video? Is it naturally matte or has it been sanded? Looks amazing! Thanks!
Wondering if I can use electrical conduit tubes instead of stainless steel tubes as I have tons of it
As I am old retired and poor could I use one of your designs for a manually controlled Mill to hog out old parts for upgrades. I have a router and 3D printer. Seems this could work in I make handles and round gauge markers for distance??? Dennis
I'd be weary of hot gluing to a stepper motor. -- I did it on my first 3D printer... -- The motors won't get hot enough to melt the glue outright, but you may find over time that it has slowly "flowed" -- especially after many hours of continuous operation. -- It may flow into the plastic connection housing, making it so you can't disconnect them anyway -- or it may flow into other parts where the glue could cause damage once it cools down. -- In my case the glue just flowed down on to an adjacent circuit board that I had soldered up myself, so, it didn't hurt anything, but I was really surprised by it.
I guess in your case, you did not use much glue, and it's on the top side of the motor, so, maybe it will be fine. -- But I'd still advise against it.
Interesting. I am going to keep an eye on that glue, thanks.
This could be a cool 3d printer design too. just add some vertical supports and switch the motor location for the z axis. Where are the build files and all the firmware? I want to make one but modify it into a 3d printer.
Top Beitrag. Sehr interessant.
Great ideas! I can't wait to see the next video. Out of curiosity can you provide a link to the cable stripper and crimp tools you're using in the video? I gasped when you cut the wires so short, because my crimp tools would have been a nightmare to use on wires that short.
I use a PA-20 made by Engineer which works really nice. The cable stripper has no name, but you should find it or similiar models when searching for "automatic cable stripper".
Hi dear friend, it is so wonderful project.
Many thanks .
best regards
Thaer Shaheen
Very good job and very good idea with the improvements. Can you please tell me how you ground the GX12 cable to GND? Do you use a Copper / Aluminum conductive adhesive tape around the shielding of the cable to connect the shielding to the metallic GX12 connector? Or do you unwind the shielding and solder it to one of the GX pins and then connect it to the GND. If a GX16-5 PIN is used, one of the PINs can be connected to the shielding of the cables. Thank you for your video and for your time.
Thanks. I unwound the shielding and clamped it in the strain relief between the cable and the housing of the connector which is connected to the grounded control cabinet.
Congratulations, beautiful video and design. Which map do you use to manage your motors. I am french and I can not find a good tutorial on the electronic part
Won't the 3d printed prints eventually stretch and warp because they are PLA and not ABS or PETG?
When you do the voiceover of your videos at night when wife and kids are asleep.... Other than that, great build!
i have the jokari wire strippers and they don't work very well on small wires. do you know of a better automatic wire stripper for small wires? (especially at a short length such as when you were stripping the NEMA motor's wires)
this is standard-setting. thanks for sharing!
Hi :) Did you get a 16 teeth pulley for the 15mm belt? Or did you use a 20 teeth? I can't find a 16T anywhere.
HI erstmal: ein super schöner Build!
Wo bekomm ich die 15mm Pulleys? Wieviel Zähne hat dein GT2 pully ? Welche Motoren (Drehmoment?) hast Du genommen?hast Du da ne Quelle? welche Elektronik benutzt du?
Danke. Die Pulleys haben 20 Zähne und kommen von Aliexpress, die Schrittmotoren haben 59Ncm und sind von Stepperonline. Elektronik ist ein Arduino Mega mit RAMPS Board.
I think that was a bad solution with extra belt. There will be cuttings cause troubles with move and precision.
Could you share some info on 15mm belts? Are those GT2? I did something similar on my first CNC but I used HTD5 polyurethane with steel cords. If you don’t mind, were have you purchased 15mm belts and pulleys? Thanks.
Interesting upgrades. I may have to incorporate some of them onto my MPCNC. Not sure PLA was the best choice; usually you see them in PETG or ABS.
I dislike ABS for a lot of reasons but rigidity isn't one of them while I absolutely love PETG but at 100% infill you can still bend it. For me 100% infill ABS would be the way to go but I have never managed to get ABS to behave for me no matter if an enclosed printer or not.
@@thebeststooge you should try ASA from rigid.ink
@EL Valenin I was so hyper for ASA when it first came out and the hype it had until I found out that if you can't print with ABS then do not even think about ASA.
@@thebeststooge ua-cam.com/video/0cGk7VK39ZQ/v-deo.html this guy doesn't think so :)
Hi, nice work there.
Question, on 2:16 you show the Roller, but the head of the screw looks "changed", did you do anything to it? If I use the normal M8 screws I think the 3mm steel would not fit through, right?
Thanks
You gave me quite some headache till I found in the comments that you had made the whole a bit tighter for the screw to fit. ;-)
However, I am not sure if I like this, so I am trying to redesign your model with a pocket for the screw-head. I hope this works too and will not break all the way. If you like, I can share the outcome with you.
It is mesmerizing to watch your build.. Is there any chance of designing 3d printer out of square aluminium tubes or pipes in future ... It could be great as it seems to available easy and cheap compared to aluminium profiles.... Once again thank you for your amazing video
Thanks a lot! The MPCNC is fully customizable, so you can make it to whatever size you want for your 3d printer and just add an extruder and hotend instead of a spindle.
Brauns CNC sure , thanks for the reply... gonna try after fixing my existing 3D printer.. Have a pleasant day..
There is another project called the Piper 3d printer that you might want to check out.
Oh yeah ... Thanks for sharing ... I will check on that 😄
Hi what extra parts did you need to purchurse outside of the standard build bom to allow you to use 15mm belts? As I would like to use the same belts.
Hi, you did an amazing job! I am impressed!
At 0:59 I saw containers, can you share a link to the model?
Anglais
hello do you have the part number used? engine motherboard...
I love this design, but I cant find the files for 23.5mm conduit, Im in the US and the only thing I can find locally is EMT generic conduit at HomeDepot which is 23.5mm
It has been awhile since you got your MPCNC going. What are its good and bad points for you?
Considering how long those belts are, that tensioner isn't doing much
How does the MPCNC compare to a xcarve beside lower price. Better precision?
Would you be willing to share the STL files for your custom parts?
I have a 3018 cnc and I am wondering if I could use the control board (grbl) off that run the lowrider 2
Hello.
I see you have only one motherboard connected to the computer. Can you tell which motherboard model
구경 잘 했습니다. 구독 (Subscription ) 좋아요(Good. Nice) 하고 갑니다.
Great Video💪 I'm thinking of building one for myself...How much did it cost you (Just the Material)?
I built one very much like this one. In total, it was around 335 euro.
What drag chains are you using there? they look pretty nice.
Hi, could you please share STL files dor double belt parts? Thanks for great video

I'm in the process of printing cnc parts, In cura i sliced the XY burly and it said 18hrs and 45min thats at 55% infill, does this sound right, thanks
Excellent, thank you! New subscriber. Cheers
Hi, du sagst so salob, es gibt genug Aufbauvideos, jedoch sind deine Teile anders in den Ecken, wie stapel ich die nun?
What model and brand are those crimpers you are using for the SM connector?
Will you update the bill of material on your website to match the updated version of the MPCNC?
BTW you are great and the idea of a printed CNC is so nice and affordable. I love it.
THANK you so much for sharing your knowledge.
Just to clarify: I am neither the inventor of the MPCNC nor a part of its official development. However you can find my custom parts on thingiverse: www.thingiverse.com/thing:3101774
@@leonbrauns ... yes I realised that some time after I posted the comment... non the less I really liked your videos about the MPCNC.
Es wäre sehr nett wenn sie noch vermerken würden das die einzelne Schraube bei den Rollern anderst montiert wird als es in der Originalanleitung ist. Habe nich darüber nachgedacht und die Löcher 4x einfach auf 8mm erweitert :D Wundere mich die ganze zeit weshalb der "mist" nicht passt aber jetzt ist es klar.
What software are you using? Autodesk fusion or something else?
Fusion
5:26 What pliers you are using. Thanks in advance
Wow, this looks amazing and fun. Was it fun? Can't wait for part 2. Are you 3d parts on thiniverse?
A lot of fun ;). I am going to publish my parts when I'm sure that they work as intended. Probably together with the next part.
Awesome man. It looks fun to build, and more fun to run.
@@leonbrauns Sind die Dateien denn schon auf Thingiverse? Danke!
Thank you

brilliant
4:40 I had a heart attack!
Consult a doctor..
Why didn't you use regular linear ball bearings?
hi great mod with the double belt . what for size is your MPCNC ?
Ich würd gern mal fragen ob du was zu den Kosten sagen kannst die die Teile in Summe gekostet haben? Hast du hier evtl. eine Aufstellung?
hi, good morning, and what the arduino project e fiIes?
and what dinencion of the desktop to work?
Question would it be possible to modify the CNC router to make it be able to cut 4'x8' sheets of plywood
It would be possible, but if you want to cut large sheets I would suggest you to search for the Lowrider CNC. It was made exactly for that purpose.
Nice video
It's very nice project, may you can share 3d file of the plan 😊
Die Dupont-Stecker an den Nema17 schaut super aus. Darf ich fragen woher du die hast?
Hay alguna manera de conseguir el despiece y las medidas
have you 3D model as step file from this machine? need it for printing if its possible.
thank you
