If you don't care which of the three switches is triggered in the probe (which is super-cool), why not just wire them in series and eliminate the Arduino? Just like Christmas lights.
Yeah, that should work too
I think you mean PARALLEL not SERIES.
@@Rollmops94 If they're in parallel with no microcontroller (all tied to a common output and input) then the circuit only breaks if all three switches open. In series (with the switches wired in a chain) any one can open and break the circuit. In the video he stated he just needed to detect any one switch triggering. So yeah, no, I definitely meant series :)
@@jamespray
I assumed it was about normally open buttons. Still nice, that you explained your idea in more detail. Probably helps someone understand it.
@@Rollmops94 I didn't consider NO switches, so in that case, you're right, parallel would be the right setup. I was thinking electrical contact from pin-ball-pin was the switch (which would be NC), but if there's a separate switch for some reason, it could be either!
Great work! There are so many amazing people improving 3d printing. Look forward to following your progress.
Never listen to those that say, “You can’t, It’s not worth it, That’s impossible”
They are never right
The problem is the slicer. We need slicers supporting 5 axis machines.
This single video answer my so many question just watching it. Amazing project please do not stop doing this great work.
Thanks, will do!
You're making good progress. keep up the good work, it's worth the wait!
Much appreciated!
Outstanding effort young man. I worked in Robotics in the 80s, we had a 9 axis robot for welding and grinding really large stuff. The robot could reach 30 feet high. was cast Aluminum and used in heavy industry, Aerospace and defense. I just know you are right about where 3D Printing can go, multi Axis, Integrated Slicers and tool changing. No only filament types but laser cutters and milling tool bits OMG!. You hang in there. I was told once you can alway recognize a pioneer, he is the one with arrows in his BACK! Its a honor to be one with you, D
19:42 I wouldn't call this shot "too close", I'd say "conveying scale" is more appropriate, considering that it's meant for just that: getting across how tiny those pieces are.
When using the meter to measure small resistances directly (under about 10 ohms), the resistance in the probe contacts and where the probe leads go into the meter can give you some error that is significant for low resistance values, and cause your meter resistance readings to be a high/incorrect.
To measure low resistance values, it's more accurate to inject a current and measure the voltage across the device. Use a power supply set for 1 amp max, then measure the current into the resistance (should be 1 amp) and the voltage drop across the resistance. Then calculate R = Voltage / Current. If the current is exactly 1 amp, then the resistance in ohms is equal to the voltage across the resistance.
To facilitate the rotation of the table, you can only pass power and transmit the temperature wirelessly, since you are making the PCB. To make the probe, you could ground the table and use a pull-up circuit on the nozzle, closing the circuit when the nozzle touches the table or use Sensorless homing with tmc2209 drivers, but the biggest work will be in programming.
Impressive work!
Amazing! Keep it up!
call this one Heracles and the next version Atlas, based on whe one that held the heavens and sky (Heracles did it only for a short while, being realistic and seeing a lot of changes in the initial stage)
You make a good point about 'why build something without having something else to make it work' going both ways
Have you considered a bowden-type extruder for this application? I'd bet removing as much mass as possible from the end-effector would increase the accuracy of probing and allow for greater accelerations/speeds
Yes it’s an option too!
@@engineerunleashed I saw a guy at a direct drive to his Prusa mini, he didn't remove the bowden drive, he just used them both. That way you can use the smallest possible direct drive (it's mostly helping retractions), and bowden does most of the heavy lifting.
Excellent work
You're doing great! I had assumed that the bed would only operate the z-axis rotation, but you're right, giving it more than just one axis could save on tool weight and reduce artifacts. I'm not sure if this will be helpful but there are ways of using belts/cables to achieve both movement and rotation, allowing you to add rotation to the tool without increasing the tool weight by adding a motor to the frame and not the tool (the same reason why belt drives are so useful). If you want an example, I found a video on youtube from "StuffMadeHere" about a moving basketball hoop that does it.
I don't know if they realize it, but the people commenting that it's pointless to make a 5-axis 3D printer because there isn't already a 5-axis slicer are basically saying "It's pointless to do something if other people haven't already done it or if it's not easy to do." I have heard a similar argument from so many people and those arguments all boil down to the same thing: "It's pointless to do something new." That's wrong, and those arguments can only be genuinely believed by people who are neither creative nor inventive.
And did those people really think that you wouldn't already know there are no 5-axis slicers? Do they think that anyone watching would be confused about that? Do they think that your project somehow would never include programming a 5-axis slicer later on? It's so easy to ask follow up questions to those arguments that make it clear those arguments were not thought through by the people who offered them.
so, yeah, its cool to make things... but if there is no application to what you make, it was pointless. something can be worth doing and pointless a the same time.
four, five, and six axis FDM 3d printing already exist, they have no real practical applications, and the few niche application they have, DLSSA is a more accurate tool.
AGAIN, something can be worth doing and pointless at the same time.
@@greedfox7842 Yes, you bring up a good point: "pointless" doesn't equal "not worth doing". But I think calling it "worth doing, albeit pointless" is a bit stern. I would say that it isn't pointless because one needs an application to have a point. Art has no application, but most people wouldn't call it pointless, the point of art is to make it because one wants to make it. This is similar, the point is to make it because they wanted to. So I think we agree, we just seem to have different bars for what makes things "pointless."
great work; i enjoy watching your work process; i find it educational; getting the summary of the good and the bad without having to do it myself. btw -- i've seen 5 axis done before, for academic papers and such. they used a bigger heatbed than you. some slicer code likely already exists, but I'm pretty sure they just hacked up existing slicers without providing feedback on the improvements. but, it would still be something to start from, so you don't have to solve that class of problems yourself & can focus on the hw/fw.
Exelent work, nice colors, looks like a test type ;)
Great job on the design, I recently got back into 3d Printing after a hiatus of around 5 years and a lot has happened. I'll be following your project!
A thing you might want to check when it comes to the resistance of your heatbeds.
Regular multimeters aren't good att measuring really low resistance values since they are only using 2-wires, you really need 4-wire measurment to get acurrate values below 5 ohms or so. An extra pair of wires to supply the voltage and the regular pair to do the resistance measuring, or voltage drop testing. You could look for a "milli-ohm meter" or do a voltage drop test and calculate the resitance based on those values.
Keep on going!
pensaste en usar load cells (las de las balanzas) para hacer el 3d probe? teniendo en cuenta q son mas solidas o sensores piezoelectricos
Te la rifaste carnal, sigue trabajando en esta impresora y quizás en un futuro todos la podamos comprar como la ender 3
great video!
I would suggest using Dielectric Grease to lubricant your slip ring. To reduce wear and keep the rotation smooth.
There is a reason why ball bearings aren't used to transfer voltage. The reason is because that electronic discharge of atoms are carried from either the bearing, to the plate, and then back again. Inevitably being one mass that neither resembles a ball bearing, or a charge plate. A similar concept is covered in how a EDM(Electric Discharge Machine) works.
This is wonderful, an Open Source 5 axis printer is just what we need, I would like to build this printer!
I would call this printer Liberty!
Naming idea: Pentaxis
(Penta = 5 + axis) Don't know whether that already exists for something. It's easy, not too long or overcomplicated and memorable, I think.
Awesome work, I never thought to make the 4 axes out of the bed and leave the z simply be the 5th!
Please also don't get so down on yourself. This is a great project. Have a list of mods sure, but no need to share them all, or maybe share them and reach out for comment on which ones are the most important to fix first.
Back in the early 90s we had 5 axis dome printers that were controlled by Apple robotics cards. The bed was stationary but the head moved around the dome controlled by magnets and a robotic arm. You're not far off from original visions for 3d printers.
Hace tiempos me comentaron que esos tipos de rodamientos para darle corriente a los cables se tienden a poner en corto y se endurece o la esfera pierde su forma por ese motivo no hice ese tipo de rodamiento, pero me alegra que alguien sea capas de haber hecho el diseño y ponerlo en funcionamiento. felicitaciones.
So what are you rotating the entire bed around the x axis instead of tilting the extruder left right around y? Is there some benefit, or it just being simpler?
No way! That purple printer on the right at 21:27 is mine.
For the flexibility in the printhead you could use load cells 🤔they don’t flex but you’d have to compensate fronte noise the could give u
also a way to probe the Z height (in your case every axis ) when resuming a print as can not probe bed when prints sitting on it so need another way for it to know its resume height to attempt recovery of print
The five axis printer sounds like it would work really well to get rid of supports for overhangs
i'd have a suggestion, team up with the dude that wants to do this too, that way you have higher chances of setting a standard for the procedure - if you both develop individually, you have 2 solutions from the start and that leads to absolute chaos and is a waste of ressources. if you collaborate on it, you can share the work and be way more efficient :)
But it can also lead to tunnel vission, maybe 2 visions that work could lead to a combined 3rd vision that works better
SUBSCRIBED!!! 👍👍👍
very interesting
Look into flat torrington type bearings, roller cage type, or needle flat bearings
Your expected and actual resistances seem to have a consistent ratio between them, so chatgpt probably has the right formula but some combination of: (1) a wrong physical constant, (2) expected a higher conductivity of copper, (3) the dimensions are smaller than expected (e.g. thickness of copper). The ratio looks to be just over 2:1 so it could also be a factor of two got lost somewhere, an easy thing to happen!
The great thing is you can correct chatgpt's predictions now with your own data
+1
Also I didn’t count the “corners” when measuring the traces length. I should have been more thorough on that!
You should just offset the 3d probe and activate it like a bltouch style probe. You could also tool change between a hot end and a probe.
Where are you from? I recognize that Spanish English accent, maybe Argentina? In any case, great job! You are insane! Happy Holidays and keep the great ideas!
Is the firmware opensource or still in development ?
For a larger bed, I might try a lazy susan bearing. Personally I use KiCAD for designing PCBs, and it can export STEP files.
That’s a really good idea! I’ll order some of those! Thanks for that!
can i adapt to my delta PLZ?
I really really would not recommend using bearings as a conductive path. They're very much not intended to be metal on metal contact within them, and the arcs can destroy them in short order, even at very low voltages and currents. Many designs of spindles do basically everything they can to ensure that the bearings are not used as a conductive path.
Great point but they should get the job done for a prototype I think, and PCBway has hooked him up with plenty of spares to keep him going :)
i was hoping someone else had mentioned this, especially since the other 3 bearing surfaces are just enig plating and not hard steel, both the bearing and the pcbs would probably wear very quickly and require replacement often. the contact points of spheres on flat surfaces are also very small, at least until they arc and wear, so probably not even better than a very small slip ring, but also slip rings can be found in different sizes for different current ratings. i dont know exactly at what point that becomes cost prohibitive as compared to this solution, but the maintenance costs and amount of maintenance time required by this also seems like it could get expensive
That’s a really good point! I’ll do some sort of stress test soon and I’m surely going to find some wear and tear
@@engineerunleashed Honestly, my first instinct is to pick up a set of brushes, the spring loaded kind for electric motors, since they're cheap and common, and run that on the heaviest plating you can get. Second is to find an old engineering text book on designing sliprings, the old engineering texts are invaluable for solving certain issues where you don't want to use the off the shelf jellybean parts. Third idea is way too oldschool for most people, in using a liquid metal pool with a probe for the contact, since that solution dates back to really bloody ancient faraday generators, but gallium requires elevated temps and mercury is a bit hard to get for most people.
Lot of the time, there's nothing wrong with the way things were done in the early days, other than it's more expensive to make at scale than something else. You wouldn't believe some of the stuff I've worked on(one of the pieces, the last engineer of record prior to me getting to it was Thomas Edison, hand lettered on vellum. How's that for equipment service life?)
Could always go with the classic slight mispronouncing the alphanumeric acronym as a word. A ‘seed’ print. 5 Axis 3D or 5A3D printer. Big things grow from small seeds :)
Load cells for mounting your hotend for probing. will be accurate and not floppy
How about the "bedswinger" as it is able to swing the bed, a step up from the classic bedslinger.
Wait nvm that sounds wrong
Amazing project, you earned a new subscriber! I would also suggest making a Patreon account, I think there are a lot of people willing to support the project and you as a creator!
Instead of using this kind of mechanism to detect contact in each direction maybe you should use strain gauge sensor. Sorry for my poor english.
che esta re bueno tu proyecto hay alguna forma de comunicarse con vos para darte una mano?
Cuando vuelva del viaje voy a crear un discord server y te agrego!
Hi, I may have already written to you. SL_ST 5D (GrabCAD model)
But again, I would like to remove your attention to my version of the kinematics of the rotary base for printing.
I especially like belt reducers, which will increase the torsional stiffness and increase the resolution of the pivoting axes.
Since the stepper motor does not allow to achieve very fine crushing, without loss of torque.

Welcome!!
i would change the touch probe to something like the klacky probe
Hey! Are you from Argentina?
Si! Pero vivo en Sydney
@@engineerunleashed te reconocí el acento. Tremendo laburo hermano! Saludos desde Buenos Aires.
20:42 Ok is not easy as Merlin on creality but i dont think is to hard. Take in acount the actua 5axis CNC is removing material and this 5axis 3D print is adding material. but the bathway and angle and this is the same. Just need contact with CNC programer. They use G code. or more actual AutocadCAM wich make the code by its self.
I'd love to get you running on better chatGPT :)
So I heard of conical slicing which...Is a 4 axis right? The nozzle theta angle as they call it is an axis.
Here we appear to have a... Hyperbolic, slicing maybe? As the bed swings like I've seen at half the vid, you'll be printing the inner side of a bell shape which is a hyperbolic plane if I'm guessing right. 🤔
This is not overcomplicating things, this is -Art- Science.
I'm missing where the actual 5th axis is unless we consider the 4th to be the extruder which would be not wrong. Cool experiment! I'm getting a bare quarter of the electronics you explain but your Creature is cool! :)
The fifth axis is the bed spinning. So X, Y, Z, swing, and spin.
Oh, right! Thanks!@@ahumanintheory4114
You should call it the tesseract 😊
Honestly I think an off axis probe will be more precise than a floppy hotend
You should call it the "fivehead". :)
Just curious, but why didn't you use a slipring? Nevermind, you answered it later.
call it "The 5x Whirly"
The Pentaprint
If you can make the bed (Z axis) tilt in any direction by 25% you can achieve 99% of Zero supports
15:20 Never ask chat gpt to do math is very bad at solving math equations even simple multiplication or even addition it is very bad. Use a calculator like the omni calculator PCB Trace Resistance Calculator
17:30 Later on you can replace the hotend/xtruder with the bondtech/slice engineering ace hotend extruder combo or the bondtech/slice engineering shortcut hotend extruder combo
I will call the 3d printer: "The 5x"
The Infiniprint
" FIVIS " (5 AXIS)
Infiniprint
I mean owls can turn their head all the way around. Why not call it the "Hooter"
*PromoSM* 😪
5 axis slicer is a big problem
1ro tremendo muy buen video. 2do Francia. 3ro aplaudo tu valor a hacer videos con esa terrible pronunciación 😊
No es valor, es de caradura! Xd
I say give it a Greek gods name.
Name it the cinco. It means 5 in Spanish
Chat GPT is notoriously unreliable for mathematical calculations.
You have to either ask for the calculation to be done in Code or only ask for the steps of the calculation and calculate everything yourself.
Chat GPT is a Language Model. It is not meant to do calculations, and results are usually not reliable.
3D-AI. I am saying the name should reference AI. Also, do you know Mahai Designs? He is building a 14 tool tool changing 3D printer. He is on TH-cam.
Why? I don't see anything on here that uses AI.
@@jerbear7952 by the time it’s finished it will.
If everyone's talking about AI, then everyone's talking about whatever AI is. If he names his printer 3D-AI, then everyone's talking about his printer.@@jerbear7952
Yes but I need to be truthful too, I don’t see how to leverage AI on this yet…
@@engineerunleashed that which you don’t know does not make it untruthful. Maybe you could involve AI in your process to see what they come up with? Maybe you could farm out the processing to them? You might need AI’s powers for the slicing. As I understand your project currently you have made a small printed for the object you are creating that you are going to move around a printhead to print is multiple dimensions. It reminds me of the rings in Contact, the movie with Jodie Foster.
so, six axis 3d printing has applications... but those applications are so niche that the machinery is basically useless.
cool video though.
"5d printer" sounds like an obvious name. And it will annoy a lot of people!
I'm sure I've seen slicers with more axis.. slicer4rtn?
