Homemade PC Arm with Special Features

- I use my shop computer for drawing and to control my CNC router. So far, it had no good place and was sitting on "temporary" desks. I wanted a better solution and built this height-adjustable arm to mount it. Controlling the CNC at standing height is finally comfortable now.

Homemade PC Arm with Special Features
This was a fun and challenging build. It's crazy how much better this is compared to little desk before.
Check out the plans: mariushornberger.com/
MEGA. Ich würde am Scharnier der den arm hält, Unterlagscheiben aus Teflon verwenden. Das verhindert Abrieb und erhöht die Beweglichkeit.
Kannst du ganz einfach nachrüsten, weil das Material nicht dick ist.
Hi little confused are you telling me I responded quickly or that I won something thank you Marius
Hallo,leider funktioniert Paypal nicht. mich würde der PC arm interessieren sowie dein werkzeugwechsler.
I would love to see how you set up the power/control board for the tools!
5:40: "If anybody comments about how weak wooden threads are ... There's 0 load on the threads and you totally missed the point"
Thanks Marius!
I used machine screws in wood for my whole CNC build. All the linear guide rails, the bearing blocks, the stepper motors etc. are mounted that way. It holds up remarkably well, so even with some heavy load I can highly recommend wooden threads.
@@Mike-Tango-Alpha Thats true. I only wrote down what Marius shows at 5:40 for a very short time. Without any personal information.
But wooden threads are so weak! 😂
(They really aren't bad lol)
@@johannesb.911 It took me some tries to pause at the message, and started smiling. Would I've known that you already made the work ... Anyway, thank you:)
Here's just a minor little theory, definitely a conspiracy theory that has absolutely nothing to do with our previous commentator, here! Threads, i.e. the type and dimensions, are selected according to the requirements such as shearing and tensile forces (Because of "fun" ... surely not!). The purpose of use, the material constants and the required holding force then flow into the selection of the right thread. A certain safety reserve has also to be planned for this purpose. Supporting frame constructions and housings always have to be able to withstand the maximum forces that can occur in the event of an accident, misuse or a defect in the internal structure/machinery(for example that a tool goes airborne or a moving part is blocked, like a ball-screw). Such incidents can and DO happen. Up to a certain degree, care has to be taken and they have to be considered in the design of the machine.
Small example: 1. We accidentally programmed something wrong: The wooden router falls apart... Great! (Most of the time it is a chain of events, that lead to DESASTER! One the hobbyist never thought of) 2. You stumble and fall on the X axis: In addition to your ankle fracture, the spindle guide also breaks off and cuts off your neck... Very Nice. Then you "no longer" have to get upset about your own stupidity:P
The cruel example was of course just a satirical joke. Or should we rather ask the health insurance companies about the idiot accident statistics? hehe.
Gruß und 3 Finger hoch: Fünf Bier fürs Sägewerk!;)
That was a hard pause to nail.
Wooden threads are pretty weak. I know there's 0 load on the threads but I probably missed the point. 😛
Love when you pulled the finished part out of your monitor. Excellent editing!
Your editing skills rock. The vids are amazing.
".. the light comes on once and then it smells" and "... this is for shit" -- Real world analysis. Love the developments you have incorporated. I could mention dust and proximity but you'll come around to that when you take off the goggles and mask you'll be using. And .. the noise proximity to your ears ... but IPODS will mask that for a while...
Yet another neat project!
Given the limited space on your "desktop" you might consider swapping out your mouse for a trackball. A trackball would probably also better cope with sawdust.
There's always that wireless logitech keyboard/trackpad thing.
They are pretty dirt sensitive, at least for me.
WoOdEn ThReAdS aRe WeAk!!one!1 Oh wait😁
You might find it nice to add a knob of some sort on that nut that locks the angle of the parallelogram mechanism. Something that allows you to grip it easily and know which orientation is correct for when it is locked in place. I feel like fiddling with the small wing nut will get old eventually.
Instead of metal springs try pneumatic springs.
Have a look at a flexarm, they use the same parallelogram mechanism and use pneumatic springs.
Good idea. I wanted to use stuff I already had
@@MariusHornberger Maybe an inflatable tube that you can inflate to raise and deflate to lower the arm?
@@MariusHornberger Also 5:50 onward "Installing the springs is a little bit tricky".
Ask your mum!!! Hehe. A bit of string from the sewing box to fix the springs during assembly would have helped. (Bavarian cable ties)
(Ein bisschen Bindfaden aus dem Nähkästerl, um die Federn bei der Montage zu Fixieren, hätte geholfen. (Bayrische Kabelbinder)) ... Männer ... pffft **g**
Wonderful project. Thanks for sharing your design, doing the great work and showing it off, Marius!:)
Great build. Love the tool changer on your CNC. Just recently watched the camera swing arm you built. Excellent! Your name is frequently mentioned on many other maker channels so you have quickly become a UA-cam legend.
1:55 _"this is German"_
lol
“And obviously… in case of shit.” Lol, brilliant, Marius. Amazing build as always.
Actually lol’d at this
„In case of shit!“ - Geil 🤩 👍
wish your emergency stop button actually said "IN CASE OF SHIT"
Awesome as always. I'm probably not going to buy a cnc in the near future, but it's so satisfying to see good and smart design built.
Off topic, but please bring back the outtakes at the end, they were really fun. Wonderfully made project. Thanks for always sharing
A wooden parallelogram mechanism with considerable force and parallelism requirements. Well done, Marius!
This is the typical Midwest dad response when he is excited about a project.
FYI. Doubling the springs x2 distance that a single one can hold.
So if one spring holds 1 kg at x distance.
2 springs thats hold 1 kg will move twice the distance. A single spring will be stronger☺️
Amazing video. Love your work. Thank for sharing with us!
j aime beaucoup tes vidéo et se que tu fait bravo beaucoup d imagination beau travaille DRUMMONDVILLE P Q
Just a bit of advice: Never be lax on shop safety. The shot where you were making the first cut for drawers to go below had your hands *way* to close to the tablesaw. My own dad is missing a thumb for screwing up shop safety just once. Always use push sticks.
Also wood threads can't hold any force man. Really should have done threaded inserts ;)
I knew someone would call him out on this. I saw it and thought... scary.
Comment Nannies are the worst.
I don't know Marius, those wooden threads don't seem like they will handle all of the stress of this thing.
/ˢ
The wooden threads dont have any stress, the only thing the wooden threads have to do is maintain the bolts to loosen and fall out.
@@haschachor8940 that's the joke. Watch @ 5:39
I realised there was something but didnt go back so i missed that, sorry my fault
@@haschachor8940 no worries at all! It was only up for 2 frames, can't blame for forgetting about it.
wooden threads are weak 😏. Just kidding, love your work
I really wanna see that probe in a video! Super interesting!
Great work!
The screen-to-real-life-extrusion was great, a really fun surprise. Great idea.
Do you sell a Fusion plugin that can Do this? ;)
Emergency stop in case of shit.
Check!
The only thing i would change is to add a 2 mm braided steel line from the top of the parallelogram through the bottom of the main (table) joint and then through the leg and over (or under it to the floor if you think about it down up) back to a bigger spring.
This is how architectural/engineering tables had various implements back in the day, only difference is the spring would be hidden inside the leg, which is not an option here.
Hey Marius, you're awesome. 9:54! ;-)
The tool changer was a work of art, and I love seeing you continue to make cool projects with it. Amazing!
A small suggestion: Most of the Industrial machines come with a trackball instead of a mouse. Might be something for you as well. Takes a bit to get used to, but great for small spaces like your table area. A desktop one will with thumb control will suite, but there are some industrial ones with bigger full hand size balls that are better dust resistant as well.
Love this project, and really want to build a cnc like yours one day, with all this awesome gear, i love the 0.1 second trash talk to the haters 5:40
loved that edit pulling a finished part out of the computer screen!
the best part was you pulling the part out of the screen
The monitor arms I have used have some sort of adjustment screw to make the monitor level. It appears they knew the arm and mount would always have some flex and added functionality to overcome it. You have probably already thought of this. :) Love the video and pulling the piece out of the screen!
Marius ,I gotta say I’m 100 percent impressed!Not only are you talented but your smart as hell! Love your content and thanks for taking the time to show us these videos you post! A big thumbs up👍👍👍👍
The engravings!!! OMG they are so beautiful and there's no need for dumb dymo labels or marker writings.
10:48 "And, obviously, in case of shit." You had me laughing out loud!
Use screws through the top of the arm, put a hole through the screws, Attach the springs within the arm through those screws, this will allow you to tension the system. Good Luck. Hope it helps!
This is the first of your videos that I have watched. Your explanations are clear, you don't have much extra footage, you show your mistakes AND your corrections to them, your speech is clear and concise, and you very obviously know your craft. You have earned another subscriber!
I can't tell you how much I missed your content. I'm really glad you're posting again. Great stuff.
Awesome project as always. I love how quickly you go through the time consuming parts. Viewing these videos its a pleasure
Great build! I have struggled a lot with a parallelogram in the past and I have never completed the project, so I appreciate this video even more.
Marius, wooden threads... So weak... I'm commenting on it 😁
But yes, I absolutely agree, thread strength doesn't matter in this situation.
This is engineering.
New video posts. Click video. Click like. Watch video. Regret nothing.
Haha, you took quite a different approch to it's specifications from This Old Tony. You wanted it to be able to carry the hardware. TOT wanted it to be able to support his CNC mill if it tipped over :P
😂 I rolled on the floor laughing when you started pecking away one keyboard button at a time. 😂😊 Love your videos
Great videos, all of them! Thanks so much for sharing!
Little side note: are you really still using screws with Phillips heads? That's a bit disappointing with regards to your professionalism!
5:58 when you have to do something like this, use strands from the copper in the core of a power line. Excellent to tie stuff together for installation.
Hi, I’ve been considering building an articulating arm but have been struggling to find a method to calculate the strength of springs to balance the load on the arm. Can anyone point me towards the method?
"and obviously....in case of SHIT" bwahahahahaha. Love the vids.
The algorithm sent me here because I just posted a video doing a similar build for mounting my camera in my shop. It was nice to see you work out some of the same issues I did. Excellent build and video, now I need to learn about that tool changer.
Always incredibly inspiring, thanks Marius!
I found advanced countries - "hospital PC stand with battery" is close to this DIY one.
Look into metal fabrication Mario bro..
Think it’s better for your projects..
Threads in hardwood are suprisingly strong so nobody should comment about the 1 frame text showup at 5:40.
You should've made your bushing in bronze there is a self lubricating bronze and you could size them exactly to the shop that you could insert since you already have a lathe
10:47 'And obviously in case of shit.' Not that obvious for me, can we see 'in case of shit' engraved on it? :)
I'm a little confused I see in this video that you have a digitizing touch probe but in your more recent video with your drill press the inserts for the table you did by hand instead of using that touch probe and just machine in something Without all that extra effort. Did you not think of using it or is there a reason you didn't use it that's not obvious to me?
What mostly you use this machine for? When it is going to pay off with all the investment? Can something similar be bought fully developed and ready to use?
It blinks one and then smokes 😅 If only I didn't know what you're talking about...
Love the vids, but I always have to skip the intro.
I don't want to see the finished product until the end!
It is amazing how much Germans like to show their "features" :D
Obligatory comment about wooden threads. XD
Warum nicht eine Gasdruckfeder verwenden. Bekommst Du bei jeder Autowerkstatt. Oder schrottplatz.
10:57 jesus christ dude. glad you still have 10 fingers.
In case of sh*t 😂😂.
Considered bronze bushings?
No, I am going to comment about the wooden threads.
Do you know how hard it was to catch that text. I'm proud I did.
I'd like to comment about how weak wooden threads are. Fortunateley there's zero load on your threads here. 😜
10:55 dont mean to be a safety warrior
it might just be the angle but this looks kinda sketch :^)
I really like your design. Would you happen to have the cnc file available?
I'm only commenting about how weak wood threads are because it took me a lot of time to pause the video in the right spot to read that LOL
whats the specs of ur computer?
what 3d software do u recommend for someone just starting out?
Hiermit erhalten Sie den Lob eines Schwaben Herr Hornberger. Nehmen Sie dieses rare Gut und fahren Sie damit fort so wunderschöne Dinge zu erschaffen.
Ne jetz ma fr. Das is krasses Zeug, was du machst. Ich freue mich auf das nächste Projekt!
Genius, 🇩🇪 respect to that germany 👍
I like the work you do everything is neat and clean that's a good quality
I feel a weird urge to comment about how weak the wooden threads are. Can anyone explain?
Yeah, me too. But I fear I might be missing the point.
bro has industrial machine at home and still has the balls to say "homemade" lol.
Super Sache, wenn Du als Abschluss Hutmuttern nimmst, wird's fast pefekt !👍
Cooles Projekt, jetzt hab ich Lust mir auch sowas, für meine CNC und mein Laptop, zu bauen.
i was watching izzy swann today and he has a large cnc and he uses a nail gun with plastic nails in it to attach plywood to the cnc bed to stop it moving
The wooden threads are super weak! Whats the point?
:)
where do i buy "incase of shit" buttons LOL!
great build and funny video thanks for show it
Who's a clever little Hornberger? :) :)
What is the name of the program for drawing, who he used?
Wooden threads are weak even though there's 0 load on the threads.
@5:40 But aren't the wooden threads too weak? 🤣 Took me a few tries to read that. Also purchased the plan in lieu of Patreon support. And @10:48 I almost spit my water out! LOL
The probe seems good, seems to be home made!
Do you have video about it?
Wonderful work! I wanted to comment about your threads… mainly about your on screen flash text … hilarious 😂
Did you know that wooden threads are super weak? 😘
Don't they sell these in China for like $15?
*points to e-stop* “in case of sh!t” lol have my sub
Fantastic Job like always! But when i saw the thumbNail of project makes me remember the Old Atari 2600! Lololol
As a Karen, I want to comment how weak wooden threads are!
Thank you fir making heavy/beefy plywood joints. so many fail, and have floppy mechanisms, steel is better, but a lot more werk.
Em uma Palavra: PROFISSIONAL!
I came here tonread comments about wooden threads
Anyone else get an uncanny resemblance between Marius and Matthias Wandel? I think it's their slightly halting manner of speech, where they sometimes say a word in a sort of unsure or quizzical way. Either way, I consider it a mutual compliment to both of them.
