Closest so far! Its actually "only" 27Gb for this video, but usually my videos are indeed between 30 and 40Gb _each_!
By the way this is officially the new longest video on my channel!! It also ended up one of the best ones in terms of editing imo, because a recent windows update apparently cleared the fault that was making my editor crash all the time, so I was able to edit it in one single piece!!
Good to see a young person getting involved with something useful , I can see a future engineer.
Great build video 👍
I love things that are so simple yet very complex at the same time. This is one. Also, cool workshop :)
Thanks :)
It's more than just entertaining! I love your videos! This one is a wonderful one! You are as meticulous as a Japanese! Your parts in wood or metal are a kind of jewelry outputs. Thank you for inspiring us! Once again, you DESERVE MUCH MORE audience! For a guy from Madagascar, this channel is really amazing. You have the right tools, minimal would I say, but you make use of them so naturally.
Thank you so much for this wholesome comment :)
There are very few people like you who realize the insane effort I put in my videos! 😅
@@ChronicMechatronic I don't agree. My friends have noticed your "perfectionism" till the details. That's why I compare you to those so precise Japanese woodwork. That demands a kind of Zen attitude and time and I'm not surprised when you said that you had to shrink gigabytes of videos to a 20-minute one. You're a pretty hardworking guy with a natural to share your experience and... your skills. With a rare enthusiasm. Thank you... I have to find your name sorry...
I'm not saying nobody notices, I just don't get it in the comments very often - maybe because we're all just too used to seeing big youtubers with their crews doing crazy things in a single video...
But I definitely see what you mean with those Japanese woodworkers :)
Anyway thanks for the praise, I'll do my best not to become bigheaded 😂
My name's Benjamin BTW
@@ChronicMechatronic hi Benjamin! Are you living in France really?
Yep, tho I don't think I will forever, some English-speaking country would be nice for a change 😂
All I can say is a BIG THANK YOU!
Love the content and I'm always wishing you the best since the beginning.
It's these kind words of encouragement that keeps me going :)
15:40 great idea. I'll take a note
Very helpful video.
🇧🇩
good job my friend , fron venezuela.
Thx
You are my hero!
I was a little irritated at the sorts of videos I was coming across. My goal is to build a vinyl cutter. Something that I can sell to other people. Which is basically just a ... cheap CNC (wait. They're building their frame from steel? Oh I guess that makes sense with momentum and the weight of the tooling and the material they're trying to work through etc.) or like... a 3d printer but with only 2 axis (and something to lift and lower the knife which isn't REALLY an axis. Not really really). Anyway, this series of videos are AMAZING! It gives me some place to start as opposed to trying to strip back from amazingly over-engineered for my needs places. I'd much rather start cheap and work out where I can stay cheap and where I have to spend more money.
Thanks! I'm glad if this series can actually help at something more sophisticated than a high schooler's science project, haha :p
@@ChronicMechatronic Laughing so hard right now. High schooler's project leads to mid-40yo making something kind of cool (the high schooler's version had far more cool factor).
nice video
thanks
Love you bro😍🥰
Thank you very much
You are very very didactic
great video )))
21:39 😳
unexpectedly and pleasantly))
thank you))
You're welcome 😊
Good ideas must me acknowledged
Starting to watch!
I liked your video
I watch the ads if that helps
Thank you :)
Though as far as I know you can skip the skippable ads it still counts as an impression 😅
It's just adblockers that are detrimental
15:07 :)) HEY !
)))))
to write a sketch on arduino, you can use the flprog program.
Yeah, I was glad my computer let me pull through with the montage, adding _all_ the HEY! 😆
Whoa, thank you, I need to try flprog! I'm not good at coding, so a bit of cheating couldn't hurt 😃
@@ChronicMechatronic
and it seemed to me that you are a "programmer"))
👍 pomysłowo
I'm sorry this will probably also be the only video in march - february was kind of hard on my mental health and I'm only now slowly getting back to the grind!
Yeah I’m sure it can be discouraging to only have a few people watching. I’ve been telling my friends about you and making them subscribe
Thank you so much 😊
No, no, it's not youtube related, though I won't pretend the channel is growing as fast as I wish it would 🙄
Just as a tip from my experience the motors from old printers and scanners don’t have a good resolution. Nema-17 stepper motors I think have a small gear reduction. I did once find a motor from a scanner that had a small gear reduction without very much backlash. You should test you motor resolution and torque before you finish your 3d printer.
I actually used it to make a laser engraver
I know, its usually 48 steps per revolution, the steppers from the typewriter I plan to use on the 3D printer are only 24 steps/r even, but since I'm using the gear reduction they came with as well as microstepping it should be OK.
I went through all that when I designed the cad model for the 3D printer, and came to the conclusion that most of the time for salvaged steppers threaded rod as lead screws is probably the best option
@@ChronicMechatronic please don’t use a lead screw on your 3d printer just for the z axis. It’ll be way to slow and I have experience with 3d printers. About maybe 2 yrs of 3d printing for me. Yes I’m rich enough to own a 3d printer.
Actually I’m not rich by any means. I just worked hard and saved
No worries, this one will only have lead screws for the z axis. I was thinking about lead screws for the future laser engraver and stuff, but I guess in the end it'll depend on how fast the salvaged stepper motors can go

I see you made the cabinet on the wall of cardboard. I'm kinda hoping now you will make a cardboard cnc machine. Not everybody has the tools to work with wood you know:)
Congrats on being first to comment on my cardboard shelves :)
Interesting idea, would make for a good design challenge, though I'm afraid the only thing it'll be good for is YT views... To make a half decent CNC from cardboard it would have to be very big, over a meter at least, and it would only be able to work on cardboard - because at the end of the day it's just that, cardboard.
I'm aware not everyone has the tools to work with wood, but I didn't have most of those tools either until I built them myself :)
Oh! Super tchecnologie
Jey man if possible do u have the circut diagram
The one for the test code I used is in the description, the one for the entire plotter doesn't exist yet. But it's documented on the github page for the modified (unipolar) plotter GRBL
Hi, I plan to make a CNC machine and follow your model, can your model make gears
Depends on the size of the gears - but I would say the plotter, no. The 28BYJ-48 steppers are too crappy to do anything really accurate. I would recommend using the kind of motors I used on my 3D printer, but with threaded rods as lead screws.
@@ChronicMechatronic Doesn't this engine feature 2037.8 steps per revolution, isn't it accurate, it features a gear set
@@ChronicMechatronic Thanks for the information you provide
The gear set is the problem, it also introduces backlash - too much backlash for a CNC router type machine to produce usable gears with fine teeth. If the gears you want to cut are like 100mm in diameter and every tooth is 5mm wide, then it won't be a problem - for everything smaller it will
please make bluetooth control cnc by hc05 module
Awesome video new sub
What about the 3d printer
I'll start with the 3D printer as soon as I finish the soldering station, otherwise I'll just have to many huge projects to work on simultaneously!
@@ChronicMechatronic alright
But please I also want to build a 3d printer and I don’t know much about it. I salvaged one stepper motor from a printer 17PM-J802-G1VS this the model number can you help me if it is good to use the stepper motor
Sure it can be used, generally the most important factor is how many steps it does per revolution, but this one in particular seems to do 200 which is equal to NEMA 17. It depends on the step angle whether you can do a simple direct drive or need to use gear reduction /lead screws.
But I'll do an entire episode about stepper motor selection and how to use different types :)
@@ChronicMechatronic thanks man
@@ChronicMechatronic please how do I know the torque
Noice
Hi 😀
@@ChronicMechatronic hello
4 gb?
haha, not quite!
@@ChronicMechatronic over or under?
@@Wol333 way more!
@@ChronicMechatronic 16 gb?
Can't give it away before everyone who might be up for it placed their guesses :)
I'll be back with the answer in a few days
I just found you have a shutterstock portpholio. Taking pictures used to be my dad’s career! He worked at GM (General Motors) and got to travel around taking nice pictures of cars. (And car people) Also I went to your about page, but couldn’t find your email. No worries, not planning to pester you. Just thought might be nice to have your email on hand. Also if you don’t want me to know your email THAT IS PERFECTLY FINE!
Yeah, I've been taking pictures on and off since I was like 12, so when I had hundreds of them I started uploading to unsplash in the hopes they might be useful to somebody 😅 After about five hundred pictures I had learned post processing so I figured why waste my time for a free stock photo site and I made a shutterstock (not really uploading anymore tho, cause I got sick of photo editing 😂)
No worries I don't feel pestered, it's not like I have any friends in the tech field anyway :)
email isn't visible on mobile (chronicmechatronic@gmail.com)
but if you have reddit you can also DM me there :)
I didnt know if Robert Pattinson have youtube channel about high tech electronic toys,,
I thought it was the last video 😐...!
Oh yeah, I guess there's a tradeoff between copying successful thumbnails and making it all seem like the same video 😂
Thanks for the feedback
like your style - but your texts over Inthe videos are *very* short - not all of us are mothertounge English .... give us some secs more to read. thank you 👌🏻🙂
I do that because in many cases it would just distract from the following sentence it the text lingers, so I usually rely on you guys to just pause to read 😆
But I'll try to make them longer 🙂
@@ChronicMechatronic even pausing with no chance😁 - text to see for *under* a second. thanks for considering 👌🏻
Can you talk less do more??
This channel is supposed to be educational and talking is an important element of conveying information to the viewer. If you're one of those people who can only watch the typical "bang bang look I built something cool" sort of videos, or don't have the attention span to listen to what I say, go watch some life hack garbage. My life doesn't depend on whether you enjoy my videos or not. Thanks for your understanding, have a great day.
