- Clem likes working with metal, but it takes longer to set up the bender and clamp the work piece than actually doing productive work with it. And it is usually much bigger than it needs to be! Just having it automatically clamp the work piece would make things a lot faster! So Clem builds a semi-automatic machine that knows when it has correctly clamped the workpiece! He uses a Trinamic TMC2130 stepper driver and an Arduino Nano and explains sensor less homing on the way! bit.ly/2EU8kQ6

A more accurate title for this video is "vertical electrical mini clamp" or something similar. Or, based on responses to comments below, "load measurement of stepper motors".
It's hard to find a descriptive title that also has search volume, thanks for your feedback
@@MAYERMAKES I reckon everyone who came to look at this video would be interested in load measurement of stepper motors.
Reading the previous (dissenting) comments give me the feeling that all those individuals are missing the bigger picture that this very intelligent young man is conveying! The negative commenters are pushing the saying "if it doesn't work, use a bigger hammer!" They don't appreciate the fact that this young man not only understands
1) electronics, 2) mechanical systems, 3) has the knowledge to make adjustments to either to overcome the shortfalls of one or the other and 4) is not afraid to follow an idea and try it out!!!
If everyone had these critics' attitudes, we'd all be still crawling on our hands and feet!
My hat off to this young man for his knowledge and will to not only try, but also follow through on his ideas!
Thanks for sharing and keep up your great work!
Listen to this man...
Thank you very much.
I disagree. I doubt any commenter here has any issue with Mayer's ability with electronics or mechanical systems, etc. They may appreciate them - although that is not what the video or the complaint is about.
When you read "automated metal bending machine" and you watch someone build a "very underpowered clamping machine" there's a disconnect between video title and video content. The machine does not bend anything. This phenomenon of "the title does not match the content" is nothing new - we see it all the time in MSM (Fake news!), but that does not lessen the disappointment when it happens.
My feeling is technical people expect a higher degree of accuracy when describing work that has been done. That accuracy is missing here. A more accurate title for this video is "vertical electrical mini clamp" or something similar.
As a programmer and hobbyist in electronic peoples always look how useful/effective it is. They never think (nor understand) that you need to build (including useless) projects in order to learn to do it and to learn from your mistakes (both in the process of making it or the end result).
It would always be fun to ask them to do just 1% of any of your project .
I could also talk about how he can influence other peoples projects. He give an idea, plan and a solution. Think it won't work? Sure if you are trying to squize a car you may need to upgrade some part! Here are the plan!
@@suisse0a0 thank you very much.
As one of the guys at our old Fabs place had made something like this up in steel, you could consider making the tool a little longer and then cut a small section out in the vertical height - so you can bend the metal without it being restricted by the tool body (so the metal can pass through during the bend).
Thanks for your ideas
What is the automatic part?
I have seen how you end up folding it with your hand
you should watch the video in its entirity, the focus is on load measurement with stepper motor drivers..so electronics as expected from an electronics channel.
@@MAYERMAKES so maybe call the video, "load measurement of stepper motors"?
@@aarondcmedia9585 it's not on me to decide that, but I think people would expect a step by step tutorial with that title, although fitting.
@@MAYERMAKES Does E14 decide the video title?
Nice build. Definitely would like to see a hydraulic solution. I know that would be costly though to get enough mechanical advantage. You'd also need to use an all-metal construction - probably tool steel on the pinchy bits, which is atrocious to work with.
Exactly, steel and hydraulics and the tools for it are just not in the budget and time frame + as this is an electronics channel. I focus on electronics
Now if you could make one that bends metal conduit for electrical wire running.. I'm sure you could make LOTS of electricians and construction men happy and you could make lots of money on it
Hmmm... Intriguing idea. Would you mind posting it on element14.com/suggestionbox so we can pick it up?
Great build!
Thanks!!
Seems like it could stand to be more rigid, there was quiet a lot of flexing going on with that english wheel, and maybe just move the actuation point further forward to make the bending with your fingers easier as it looked like you were struggling there.
the english wheel was added in the very last minute so of course more rigiditty would help, the reals struggle wit hbending was reaching around the camera to get aclose shot without putting my hand in front of the lens, thats why< the hand positioning is so akward.
Nice experiment. The machine looks a little whimpy though.
If I had the means time and budget of course I'd prefer a cnc milled steel frame but I have to use what I can afford.
Will you do a video on how to build the Deadly Deathray Machine shown at 20:12?
I actually did a series about it on my now defunct old channel in German, you can watch it still on Lbry.tv if you search for mayermakes
All those downvoters and those posting negative comments should consider that Clem has shared a lot of information, designs, code, etc. in this video, even if they don't like the final result.
He's shared his 'issues' with us for the good of others. I always say it takes a big guy to do that. Many of us would keep quiet about them.
He's done some great other projects and I know that he's always worthy of a 'Like'.
I'm sure that just about anyone watching this video could spend hours with him over a few beers, talking with enthusiasm about maker stuff. I'm sure that he would be a great friend to like-minded people. With this in mind, maybe think twice about the negative stuff ?
Thanks, that's very kind of you, I actually do spend hours over beers with anybody who wants to nerd out. Usually at Maker faires.
Why didn't you automated the actual bending too?
Have some sort of tray? On a gear system to slowly bend the metal into shape?
the force limits would excert the capabilities of the motors eve nwith more gearing , the reasoning is explained in detail in the video.
Nice
Ambitious project given the time and budget constraints imposed by Element14, it seems like a solution in search of a problem though. A better way to implement this sort of clamping would be to rig up a foot pedal and ratchet system, then there's no need for complex code or any electronics at all, but then on the other hand, it wouldn't end up on Element14 in that case.
What I was expecting to see based on the title was more in line with a press brake that automatically detects the metal thickness and then produces a bend based on an entered angle.
its about electronics and exploration, I rather have fun tinkering with electronics than dealing with mechanical constructions, while they would work and are easier, I'm here to build stuff with electronics as you correctly assumed
@@clemensmayer9171 Doing a project in the pursuit of knowledge is never time wasted, I've made plenty of things of dubious practicality just for the sake of learning something. I definitely don't take any issue with the content, you set a goal and met that goal, I just found the title lead me to anticipate something a little grander than what was intended.

Useful to bend thin chocolate sheets !!!
You: "I don't want to act like a caveman doing things with my hands"
Me: Excitedly watch 21 minutes of video to end up seeing you bend the metal with your hands anyway.
You're obviously a brilliant guy, but this project is awful because it isn't even CLOSE to the title. "Automated Metal Bending Machine" is not what you made. You made an electric clamp. You bent the "very tiny" metal with your hands. In fact, you had to hold the top of the clamp in place WITH YOUR FINGERS while you bent the metal with your thumb. You could do this with a $1 C-clamp and a piece of scrap wood...
I love this video, although the code indentation and format killed me a little bit.
you are welcome
Whats wrong?
You should be using an esp32 not an underpowered arduino
ans ESP32 would not change a thing besides the library is not working on anything other than AVR chips. no gain of going with an esp in that case.
@@clemensmayer9171 Oh dear. another case where a joke doesn't come over as intended.
@@AJB2K3 you haven used sarkasm or joke marks
There was no forming, nor bending here. The arduino literally just actuated the motor to hold down the paper like metal while you bent it by hand.
And that is explained in detail throughout the video. On most metal brakes the clamping is the time consuming part, not the bending.
La que lía para doblar un hierro... XD
Hlw sir how to design one time on and Off timer circuit with continue power supply not trigger
Search for 555 timer circuit on element14.com, you should find easy to follow tutorials.
So u automated a holder to bend with hand a piece of metal sheet . U can use a wise to do same thing u do , and its not that complicated .
he focus of the project is to explain how load mesurment with modern stepper drivers works. Sure you can use a vise for tons of applications, but this is an electronics channel so I build projects centered around that.
@@MAYERMAKES A motorised vice? You might not be able to get a crush strength using lightweight motors (perhaps some gears and a toothed belt may help?), but there may be other electronics that could be added / used? - something to help with positioning angle, distance protruding, etc??? Just a random thought ;-)
tanto trabajo para que en realidad solo sea una prensita, yo creí que iba incluir el doblez automatico, que chafa
Is this a joke? what the actual...
If you are reading this god bless you ❤️✨!
Seriously, atleast attempt to make a mechanical construction with a gearbox or something so it gets enough torque. This is just embarrasing to watch really when the end result is a plastic thing gently touching the metal and alot of extra force is needed to bend it....
You need to watch the video again, all you are efering to is explained and demonstrated in there. I made a planetary gearbox for it. the point is to demonstrate how load measurment works with modern stepper drivers. the clamping is strong enopugh, bending the metal vastly exceeds the capabilities of the stepper motors even with more gearing. As explained in the very last segment Building a full bender would require soem bldc motors or a hydraulik system which would break the budget.
@@MAYERMAKES Alright. Yeah I skipped ahead to the results.
A vice is cheaper and much more capable than this thing.
Useless...
Lots of work in mechanics, electronics and coding have gone into producing a weak kind of kind of vice!
It's a bit like claiming to have invented an automatic meal-maker that uses elaborate technology to merely push a dinner plate in front of you !
