Carrot fingers got me.
That scared the shit out of me. I thought the crunch was his real fingers.
It took me so long to realize what was going on (almost to the point where he pulled his hand away)
This was absolute gold. The wordplay, the build quality, the storytelling.
Great job man.
You prolly dont give a damn but does anyone know a trick to log back into an Instagram account?
I somehow lost my account password. I appreciate any tips you can give me
@Aldo Melvin Instablaster =)
@Owen Kaden Thanks so much for your reply. I found the site on google and I'm waiting for the hacking stuff atm.
Looks like it's gonna take a while so I will get back to you later with my results.
@Owen Kaden it did the trick and I now got access to my account again. Im so happy!
Thanks so much, you really help me out!
@Aldo Melvin no problem xD
Your fingers grew back very quickly, what's your secret?
vegetables.
@@reps jajaaa,,,nice one
tbh that kinda spooked me, even though I knew they were carrots
Lots of carrots and salamander DNA.
He is one of those lizard people like Mark zuckerberg :D
I haven't laughed so much listening to an engineering video before. You are a funny man...AND a brilliant engineer and a great presenter.
6:58 I just assumed that you always used your "full rigidity" voice when making videos.
Your comedic delivery is impeccable. Your projects are a hoot too - keep up the good work.
your toes got pretty lucky in that end scene
plot twist: they actually got smashed, but I am too cool to show any sign of discomfort
I was waiting for a "third time's the charm" moment.
Can't see his face while that, but he bites his lip and the eyes are full of tears, after the camera was off, he was rolling on the floor and finally fell asleep down there with the thumb in his mouth in fetal position 😂
Marco Reps you are pretty cool 😎
He had his safety socks on, nothing can go wrong with those
Roomba with a speaker for directionality test. I laughed.
Oh don't denounce that Xiaomi
I love the idea of a surface meter with a record needle... maybe we're onto something here. DIY arduino surface roughness meter anyone?
An old British television programme called Tomorrow's World once showed a device for counting sheets of paper in a ream using a turntable stylus to detect the individual sheets and some sort of CPU or microcontroller (1980's style) to count and display the result.
Yes, nice idea. But maybe this turns into a surface-irregularities-only_when_in_motion-measurement-device?:) ... -> electromagnetic phono cartridge -> AC. We have to look for a piezoelectric crystal pickup type.
Spiral out, keep going. Not so easy with a fixed needle. Great progress on your monster CNC!
The sound the Bluetooth speaker makes when it turns on is the same as my 7€ Chinese Bluetooth amplifier motherboard 😂
My 2usd one does it too XD
yeah my 3€ china import does that exact sound too :D
i forget which one of mine makes this noise....probably a few
10:47
that was officially the most beautiful rendition of lateralus ive ever heard
Was about to ask if that was tool Is that a remix of lateralus
@@dos541 yeah...remix
Imagine the monumental 3D steel dickbutt that will be printed on this thing.
printed?!
I think the fancy de-coupling stand invalidates the main use for powerful speakers: laying them flat on the ground at max volume to retaliate against your neighbors playing music too loud.
"I am immeasurably excited 😐" 😁😂
Mounting stuff alone on not so tiny CNC machines... I know that feel.
alone ... I know that feel
jk, got doggos
going to a machinist to machine parts for your own machine!
machining companies employés: ONE OF US!!
I love the little nod to tool lol.
I look forward to your videos every time! Can’t wait to see that cnc in action. Much bigger than the mpcnc I’m building.
VERY happy to see that Steel Mogu vinyl at 8:14. I don't think I've actually met anyone else who listens to Iglooghost, so it's always cool to see other people listening.
oh lol watching a bit further in, there's clear tamei as well. Again, always cool to see
I lol'd at the Tool Easter egg - so many layers!
OH BOY! I haven't watched it yet but Marco, CNC and audio.. all my favourite things in this universe!!
Oops, I forgot my wife. No 4.
(don't set you expectations too high in the audio department :)
I gave a like because of your choice of music at 10:50
It's played from a .midi file and slower to prevent copyright detection. And music identification apps. So nobody will ever know.
"Honey, I need a 4th axis for my not even finished overbuilt cnc machine, so I can play my vinyl". Not gonna lie, that bit about using the needle as a surface roughness indicator could have some merit!

YOU KNOW THE DRILL
I accomplished the same thing the rubber speaker stand does quite accidentally when I removed the crappy plastic stands my Sony home theater speakers came with and replaced them with two thin vertical dowels coming up from the small shelves they were mounted on. The flex in the dowels provided some natural dampening which reduced vibrations from mechanically reaching the shelves and wall. Cheap as hell but they sound better than the huge $500 floor mounted speakers they replaced.
“are giving me a lot of rigidity” lol 😂
Amazing challenge and application. Be proud
thanks. am :)
Beautiful job, dude. The CNC is fantastic already! 😃
If you're willing to take it back to get machined again, you could do a variation of a toe clamp. You mill the space adjacent to the rail (on the outside) and drill holes and have them threaded to accept offset screws that will press a piece of steel to the rail. I think it's a doable mod (to the current statvs qvo).
wow I have just seen precisely that in this hiwin catalogue under 1-10 www.automation4less.com/pdfs/hiwinaglg.pdf
I had a large bench vise slip out of my hands, landed on the corner of the vise and went through the linoleum floor and took a chunk out of the concrete below. I'm not even sure steel toed boots would have completely protected me from that. It missed and I was completely unharmed but it was a huge wake-up call.
i think steelboots would have at least prvent a cut off toe
Pretty sure good quality ones would save you from that, they need to resist 1,5t of force without too much bending in order to qualify as safety boots. Sure, that is just static pressure but out of personal experience i know that good boots can withstand nearly 3t w/o visible deformation (just don't ask). I just did the math and it turns out that a falling 100kg object with a 1cm^2 diameter (and terminal velocity) would create a pressure nearly two times as high as having a 3t load on the entire cap. That would probably make a rather large dent (or hole), but given that this would be the absolute worst case (terminal velocity, extremely small area of impact, no tilting [and therefore landing alongside your boot] of the object etc) i suspect that you would survive with your toes (almost) completely intact (you still might have to call an ambulance to get you out of your deformed shoe).
grate! try to use your cnc just with x or y axis as tangential tonearm!
Good video of yours and that is our honor.
The needle vibrates side to side as well as up and down, so the needle needs to rotate with the record. Check out the Real Engineering video on vinyl.
I worked as a Field technician for a Swiss CNC manufacturer, and we face some of the same „ghetto“ mounting issues when changing 120kg spindles on 20 year old machines for example...
Once again real quality content, love your videos.
You made my day, greetings from Spain
9 minutes out of a 12 minute video I sat here, and bored myself to tears.
Man, that was so awesome.
Danke fuer deine Arbeit.
You finally uploaded :D Happy birthday / Alles Gute nachträglich, Marco ;)
Thanks ;)
This video starts hurting when you take out the vinyl record. And it gets progressively worse from there.
I like it.
DJ ROOMBA IN THA HAAAUUUS!
I love how you are literally 200 IQ but you still have memes in your videos
The higher the IQ, the more you meme
Looks really cool.
I can tell you are in good spirits with this project; you make more jokes when you're accomplishing things and its awesome XD I love your humor XD
what a madlad just dabing on his heavy duty cnc machine in his living room in a carpet and then tryes to use it as an record player nice vid
well if you put it that way
You Sir, have made my day. Thank you.
The vacuum cleaner gives a new meaning to "surround sound"...
Has anyone done an inverted dual drive for each axis? That way quick precise movements can be made and the inverse drives make up for each others backlash, and the steppers can be set up out of phase physically so that when one is on a full step the other is on a half step, then just adjust the timing of the screws to have no measurable backlash but with the least resistance and screw pressure
At the start, you showed the T12 Soldering Station. I have it, and would really want to see you review it!
Great video! Your best yet
That Z axis is overbuilt it by a factor of about 200x. You can remove about 90% of the metal and it'll still be just as sturdy. All that weight will limit your XY travel speeds and cause a lot of unnecessary backlash.
let's agree on a factor of 2x
@@reps Considering all the torque on the spindle will be lateral, there's no need at all for that thickness, since it'll never twist. You can also mill out the majority of the center section, leaving ribs, and it'd be just as stiff, with a lot less mass to swing around. You can see how much backlash you're currently getting, the entire frame is shaking, imagine what that's doing at the cutting surface every time there's a direction change.
i wait your videos more than my parcels with parts from china
Just the perfect amount of dry-ness to keep the fun at bay. :)
Lateralus!!! Perfect taste :-)
You are so amazingly entertaining. Such a fantastic job. Wow...
rule of thumb: If there is a question mark in the title of an article: the answer is always "No!"
oh hell, you are killing me, made me run into my studio and hug all of my vinyl, while wearing vinyl bodysuit. speaking of rigid.
You're one of my favourite channels
Thank you
Interesting idea putting it atop a vacuum. I never would have thought of that. Please post if you ever do manage to get a CNC machine to play a record.
I have electrostatic speakers for more than 10 years and they are very good.
All you're missing is a laser to read the lines. This is far more complex than the idea I had for old records 🍺
I think I've seen a laser record player available commercially, that gave me hope that this might work as well. (But the needle ended up bending when not moving in the intended direction etc)
@@reps a high quality photoresistor and decently filtered DC power supply with a finely focused 405nm laser would be perfect for this project..
No contact reading with a simple op amp circuit would save the headache of 'micro crashes' until you get the movement dialed in.
At a fine focal point at ~1mW won't burn the track.. Though be careful if you try, the 405nm can make the smallest spot but will heat that highly absorbent black record even at 5mW, and possibly distort the track.
Cool project none the less..
100% awesome. Was this ever revisited?
this is the longest, most in-depth, scientific, engineered and amazing troll of all time...
Hmm... having a turntable spin the record and using the cnc to move the cartridge laterally would be hard enough I think. Remember, in order to get sound from a cartridge, in the way it was meant to be used, the cartridge cantilever axis must be tangent to the record's track and facing in the right direction with respect to the direction of the records rotation - you don't want the cartridge to be facing in the opposite direction as it will result into the cartridge jumping off the track or worse, the stylus or the cantilever snapping off. Also, you may get away with having the cantilever at an odd angle (e.g. 90 degrees) to the track when the cartridge has a conical stylus risking some slight damage to the cartridge but with a more expensive elliptical or other narrow profile stylus (fineline, Van den Hul etc.) you will probably damage the stylus as it is a finer and more fragile stylus than a conical one. Last but not least: don't presume to know what the distance between the tracks is. The track, although a spiral, does not have a constant recession rate. As a matter of fact, it is constantly changing depending on the level of the recording at each point in time so as to pack as dense a spiral as possible without running the risk of the track undulations overwriting into the already written track from one revolution ago. So the recession rate is constantly changing, at a non-audible rate of course. In order to calculate this rate precisely a recording (analogue?) computer is used -an expensive piece of gear- which is fed the signal to be recorded and which controls the lateral record head movement of the recording lathe. So you need some way of sensing the spiral recession rate at the exact spot where your stylus makes contact with the track or have a sufficiently compliant system to permit the stylus to move along i.e. a turntable tonearm. As you don't have the latter, I expect you'll need to somehow extract the lateral acceleration experienced by the stylus from the audio signal recovered or perhaps use a couple of piezo sensors on each side of the cartridge that would be used as a means of mounting the cartridge to its carriage mechanism. Having the piezo sensors used as mounts for the cartridge would of course affect the audio quality of the recovered signal (as in effect the pair of sensors would operate as two additional low quality cartridges in series with the stylus cartridge). So the best method, in my opinion, would be to attempt to extract the sub-audio frequency components of the cartridge signal. There's only on problem with that: there won't be any as cartridge have a low frequency cut off point of about 20Hz if you're lucky. So you're back to the sensor method. Perhaps, instead of piezo sensors, linear actuated coils could be used. I have no idea where you'd find these. If they weren't so heavy and bulky two subwoofer motors might do the trick but they're probably low frequency limited too. To give you an idea of the frequency of the recession rate change, for a 33 1/3 rpm record, assuming the distance is adjusted once per revolution or more often than that, you'd need a sensor with a low frequency cut off point lower than 33.333/60 = 0.55Hz or 5/9Hz. If the distance is adjusted at a slower rate (e.g. every couple of revolutions) then an even lower cut off is required e.g. 3/9 Hz or 1/9Hz etc.
hi Marco
this is a beautiful selfmade cnc
hi liboy34
thank you!
Make sure you knock the edges down (with sandpaper) on the poly / lexan windows otherwise they will crack !
Finally a video! Quality over quantity
not today, I am not very happy with this one :\
Not sure exactly what you're trying to accomplish (other than why not? Which is great!).
On a real turntable, the tone arm isnt forced to move. The grooves on the record impart the radial force to the stylus and it follows the spiral groove. The exact spiral is different for each record.
what about using a CNC rotary table - also i believe LPs were meant for 33 RPM instead of 35 - but there's a 45 RPM for singles
info tech Yes I also picked that up.. huh.. 35? at 11:03 👍
Old records played at various different speeds. The most common ones were 78, 45 and 33⅓ rpm but, particularly for the spoken word, there were others:
en.wikipedia.org/wiki/Unusual_types_of_gramophone_records
Maybe use a stepper controlled rotation base for the record and just use the Y or X axis for controlling the head motion?
I think the axis of the cartridge needs to stay tangent to the spiral groove of the record to work properly. Just moving the whole thing to follow the groove doesn't seem like it will work, as the stylus is designed to move from side to side to follow the record grooves. I guess you could let the cartridge swing freely, but that isn't ideal either, as the cartridge will move a little with the record groove, instead of the stylus doing all of the moving.
The startup sound from this sounds identical to another BT speaker from a company called Cellara...hm. I'll have to check Dave's video, to see if the guts are the same.
aserta startup sound is the same as the ~$10 chinese bluetooth speaker(s) I have. probably the same chipset.
still so good
What does this guy work as?! I wish I had access to such a heavenly tinkering environment!
he's just, literally, at home. and spends thousands for these parts. And a lot of time/waiting. You forget he releases (makes*) these videos like once very few months. He's not got the free time. And again he hardly has any tools or a "tinkering environment". You're just letting your emotions, ahem, JEALOUSY AND ENVY, get the best of ye.
Iglooghost vinyls gave me an unexpected rigidity. Please accept my firm but sweaty handshake.
A long boi, an expensive boi, a heavy boi
Rigidity!
lol, early thumbs up for the speaker riding the robot vacuum.... :D
lol, torturing vinyl aficionados....... actually good idea!
Are you related to the designer of the Bismarck class Battleships? lol. man, you design things very well. I'm not sure if I should be envious or Subscriber proud of your intellect.
Great projects ! Short comment - you have quite big Z axis which move your center mass much higher from the base and as the result more vibration on high feeds .
I use much lighter machine ( with ALU plates ) and already have 300+ KG base to decrease vibration on high feed moves .
About carrier installation - better not remove plastic stoppers from carriers when installing the rails .
All my carriages (new old stock) came with pieces of foam instead of those stoppers
CNC envy. She's a beauty.
I'm a simple man, I see a Marco Reps video I click like and share.
A huge CNC Machine in Dachgeschoss believe that too should be reconsidered, don't get me wrong i admire your work but i couldn't pass it without commenting ( I'm a very passive viewer i just watch) and by the way your reviews have an enormous credibility in my humble opinion.
Wow, High/Low tech
Thanks for sharing :-)
Engl: The Speaker is called an elektret speaker it can be usefull especially in portable applications
erman: Die Lautspreher heißt elektret lautsprecher , gibs auch in die andere Richtung Mikrofon, hat seine vorteile gerade was Portabilität angeht (Leistungsausbeute) ist aber nicht ganz einfach unter Kontrolle zu bekommen
i hope you fix your lateralus rigidity issue

do you wear them because of how well you understand physics or maybe dont? hahah great video !!
The spiral of a record varies depending on how deep adjacent grooves are. It would be almost impossible to play a record correctly the way you're doing it. If the record spins at the proper RPM, you can calculate how many steps/second you have to take on the X axis and then use the CNC as a super-precise linear tracking pickup.
The spacing of the grooves depends on the amplitudes of the signals in adjacent grooves.
Also, the hole isn't necessarily drilled at the center of the spiral.
I don't know how you can track it properly unless your tracking to zero out a "DC bias" in the forces on the needle.
You madlad!
Maybe if you use spindle rotation to spin the record and one of the other axises(?) to move the needle?
Playing a record with a preprogrammed path will be hard. On some records the grooves aren't even the same distance, because they widen with the volume of the music.
I don't know how he does it but Marco Reps makes a german accent sound sexy.
@2:00 Nice explanation! Don't buy electrostats though, I did 14 years ago and can't go back anymore. I tried, but failed. They aren't full range though (hybrid version like the Martin Logan's you used as an example in this video, mine are the previous generation from ML) because it has to be " "somewhat" convenient.
The vibrations through the column to the needle will surely swamp the signal in the record, won't it?
You are amazing... ! 😍
Try to cut a groove in a relatively soft metal, like brass. like an extreme version of Edisons wax cylinders
amazing
