- First step in making a Closed-loop stepper motor, the mechanical part.
I get it, you guys don't like the music :)

Good video bud, but bad background music it's very distracting. Take that as positive criticism.
The music used in this video is incredible!
nice background video for the jazz music, which I clicked the video for, of course...
the "music" is scarring my ears!
wow! I can't believe what I just read. what are all these people listening? mate, you have an exquisite taste of music and the video is just great. thank you for sharing
Arg! That background "music" is doing my head in. 😱 Nice project though. 👍
The project, the video AND THE MUSIC are all great, IMHO. I'm so bored by that mindless rock/heavy metal whatever you call it. Kudos! Well done!
This guy's videos are incredible!
+Christian Lewis Thanks man!
Great content, could not watch until end music was nasty.
hi kris thank you sharing..
how do you eliminate backlash problem between two gear?
exactly what i was looking for
💯
You gained my like when you tapped with a cordless drill very old machinist guy move
I believe this is a great video, I know little of the electrical world so is this correct or no, if I mounted a rubber wheel to this then I would not need a lead/ballOr any other driven screw belt or rack and pinion correct?
I actually loved the music...
Thanks for a great presentation! I did not watch the video for its music content, although I guess the Jazz fans aren’t exactly speaking out in support of your choice of background music.
I was looking into the trade-offs between the effort needed to use an encoder on a lead screw to compensate for backlash in a geared stepper, but it adds more complexity than my simple project requires. Sometimes there is no substitute for using directly-coupled stepper motors, but I can see use-cases where this would be necessary for machines that must not skip any steps, and/or for applications requiring extreme precision.
great info and wonderful detective type music. :)
Nice bracket build but why not just add an encoder to the back of a double shaft step motor? All off our low cost double shafted stepper motors are pre-drilled and tapped to accept two common bolt circles for encoders. Jim at Applied Motion.
Haleluja ! mein lieber Herr Temmerman ! Sie sind ja offensichtlich ein ausgebildeter Profi-Mechatroniker der Neuzeit hahaha ! Also die Ausbildung hinter Ihrer persönlichen Leidenschaft schöpferisch zu sein und zu wirken, hat sich wirklich gelohnt, Bravo !
.............................................................
Ich danke Ihnen für diese tolle Arbeit , und mache mich sofort fertig, nach Ihrem Model 1:1 es nachahmen. Die Details + das Ergebnis werde ich ihnen später natürlich mitteilen, mit der Hoffnung einen Vorschlag im nahliegenden Bereich zu machen. Also bis bald und bleiben Sie gesund. Alles Gute
Nice work! Can you provide the link for that optical encoder?It will be really helpful
Nice Can you provide the link second video for that optical encoder It will be really helpful
could you put a CAD template file up for the plate you made up? and some gear ratios?
What is the crazy music? I love it (now), however the link doesn't work
Nice video - VERY clean fabrication! For the record, I like the music - reminds me of a modern-day Brubeck arrangement - Kris, really like that spindle on your CNC mill - can you tell me about it?
Music remembers me of my lectures of Boris Vian’s novel “L’écume des jours”and his pianocktail he designed. It maybe my imagination but when reading that book I was earring that kind of music wondering what kind of cocktail it might have given.
what type of CNC milling are you using ???
Hi! What is the make and model of your milling machine?
Wow, all I need to do is buy my own metalworking shop
attach magnet to the back of the shaft and use a magnetic encoder IC?
Good job boss
Music is banging.
excellent ! video
where did the gears come from?
Hi Kris, would you share how you´ll control that? Thank you in advance! Btw, amazing job your robot with visión system integration
roma1530 Thats the plan :) hopefully the video will be up somewhere this week.
Could you share the name of the encoder ?? Or amazon link ,please
Wow.. this is cool. What's funny is I'm using that EXACT same rotary encoder hacked into a USB ball-style mouse for playing MAME games like Arkanoid. Now I can buy 3 more and upgrade my CNC router :)
What kind of drill press is that?
P.S. I don't mind the music.
where can i find a documentation or contact you?
What is the accuracy of the backlash on CHEAP plasic gears? How can that possibly be considered accurate?
What the name of that machine you used to make hole on that plate
Please tell me someone
What is the 3D designing software?
Hello ,
What Design Sofware did You used to make those Drawings ?.
THANK YOU .
MARIUS Petcu It's rhinoceros. :)
what software you use for design?
That machine is awesome 2:00
What name is your drawing program in 01.00?
Please tell me all machines name you used
Why did not you drill the holes with the same cnc mill?
Something about the jazz sounds sinister. Combined with my brain thinking about the backlash in the gears, I feel weirdly uncomfortable right now. What about gt2 pullies instead of gears?
Also, I can't tell if you have piercings on your hand, or just metal chips stuck to you.
Man that sounded like someone neutering a wild buffalo, Wow !
any info about this encoder
PLEASE continue to make videos with this wonderful style. The music is a fantastic break from the usual style of music on machining videos, and you let your work do most of the talking, which makes it great to just put on in the background while I work.
The music is horrible!!!!
TuningGuide007 ignoramus
Lol, no offense, do you mean you have to Ignore the music. I guess it's not my kind of music. But I really wanted to know what a closed loop stepper is. So if you mean I'm know-nothing at this topic you're right ;)
TuningGuide007 It's OK, luckily, tastes are different! Some music needs to get acquainted with, unlike the "easy listening" stuff blaring out of the radio 99.9% of the time.
+TuningGuide007 The music is great
@@TuningGuide007 lmao doesn't even know what the word "ignoramus" means... it means you're a simpleton, mate. The music is fantastic, it's not in your face and distracting.
that music. holy fuck. i can deal with horrible, but the level changes. my fucking god.......
Nice video :) How do you use the router with aluminium? Is it a dedicated router or home made? Is a special kind of aluminium needed and we're do you get this from? Special Mills? Sorry for the amount of questions:)
+Frank V
He can't hear you over the katzenjammer.

What do you use for make the metal piece?
Metal.
I'm curious to know how to generate the pulses for the stepper drivers, pwm I mean
I'm trying with interrupt timer handler , I'm trying with internal pwm but I'm not able to read the pulses somewhere , now I'm thinking about to generate pulses by using a VCO but I have to rea the pulses too....ufffff
Walter Porcellini Hi Walter. You probably don't need PMW to controle your driver? You just have to set the drive pin to HIGH and LOW at a relative slow pace. good luck!
If I wanted to listen to music? I turn on the radio.
Hi Mr.Kris Temmerman!
My name is Hoa, I am from Viet Nam,
Your video very helpful, could you give me the address where I can buy the plastic gears.
Thank you very much.
Nice video, but the music... dude? :D
Can you please help me to make a code for dmx stapper motor with encoder
catchy tunes
Hoi Kris, wat gebruik jij als smeermiddel tijdens het verspanen,wat je er telkens op smeert met een kwastje?Alvast bedankt man
Hey, was een of andere biologische afbreekbare cutting oil (rook naar frituur olie als het te warm werd ), lokaal gekocht. Maar die is ondertussen op. De laatste tijd gebruik ik geen smeermiddel meer, enkel een permanente luchtstroom om chips weg te blazen. Is goed genoeg en is veel properder :)
Bedankt voor je antwoord, gebruik ook geen smeer middel maar vroeg me af of het niet beter was om het wel te gebruiken!niet dus;) en trouwens, ze hebben wel gelijk. Die muziek kan echt niet:)
The music is randomly altered to avoid copyright infringement.
Also known as "Jazz dithering". Hmm, nice.
Hmm, I wonder what would happen if you ran your cnc file through a music editor.
Very clean! and good music :)
can we have the cad file?
No man!! Good video but dammm that music is excruciating
Kris, this music is like scraping nails on a chalk board, could you stick to something that is more smooth flowing jazz or classical music?
I like the music, its a smorgasbord of noise
Great video!!!, but please.... no music.
I would install 3 encoders. Just to make sure.
Why do you need to convert them into closed loop?
+ah lee
The stepper motor receives a pulse, but the motor doesn't move. You now have a missed step, throwing off the accuracy.
The best way I can think of to describe what may cause this issue, is if you are working with wood, for instance. The toolbit is moving along just fine, and all of a sudden it comes in contact with a dense knot in the wood. The toolbit attempts to advance to make the cut, but instead remains in position, thus causing a missed step.
There are several reasons why this may happen. You may be trying to take too deep of a cut, or you haven't set the spindle speed to the proper setting for the material you are working with, or you are advancing the motor faster than the toolbit can clear out the swarf. Sometimes simply changing the bit from a 2-flute to a 4-flute can remedy this, otherwise, slow down your cuts. Haste makes waste.
In a closed-loop system, the encoder sends a feedback pulse back to the control software for each advancement of the motor letting it know if the motor actually moved. If not, the control software will make another attempt at making the cut.
If your control software allows for it, you can set it up to halt the operation at that position. In this manner, you can make proper adjustments to the CNC machine, then continue on from there, thus avoiding ruining the part that you are cutting out.

oh that music!
te falta rock en la sangre....
why that music doe
Kris, you do really pretty work and I was interested in your video. But the music was so loud and such a distraction that I had to stop mid-way through the video. Not that I matter, but I suggest you consider dropping the music altogether.
What's the aim of that ???
LOVE THE MUSIC!!!
Great vid. Thank you.
Painful noise in the background. Is that music? Sounds like ducks being hit with cricket bats :p
LMAO
what is the gear ratio?The music is ok but your voice is so soft it is hard to balance the two volumes.
The music stinks! Am I the only one who feels this way?
well he enjoys the music and he isn't the only one. true though I don't like it, but very few people like my music so. yeah.
we all have a programmable drill....yup
Great music!
What are the advantages of a Closed-loop Stepper Motor?
You can detect when you stall it. Running open loop in something like a CNC machine can result in position errors and ruined parts...or worse. With open loop the controller says, "move 10 steps" and assumes it happens, but has no way to be sure. If the load exceeds the torque during the move, so the stepper actually only does 5 steps, the controller now is off 5 steps worth of motion. The error can accumulate it it keeps happening so you end up cutting where you hadn't planned to. Ruined work, broken cutters, ruined hold downs, parts flying....
With closed loop the controller can tell when the motor stalls. It can command the motion again, shut down and call for a human, take a lighter cut or whatever else you write the software to do, but t isn't blind to what's really happening.

Thanks :)
I love the jazz!
Then again, yuck. It has no real key or rhythm...
good vid but pless no music
Everything nice 'n fine but what 's with the 'musick'? Pls note this is unbearable!
u didnt like the music?
The fuck is up with the music!
I like the music. Where can I buy the CD?
Je comprend pas
:) I actually like the music. It is cool!
Actually, I kinda liked the music.
love the free jazz
oh man, i was about to complain about the music, then i read the comments below, and i just could not do it
This music is the shit
if you listen to music must go to rock saloon.here is technical area...
I love the music
Bu müzik ne böyle 😂😂😂
that is a verry random music instrument ensemble. i believe they couldn't play the same exact arrrangement twice
How about, just buying a stepper motor which all ready have encoder built in?
Save some machining time and space too!
Sometimes it's all about the process and enjoyment of making things.
99% of the comments are about the music being terrible.
