Oh any hardware I incorporate (eg bearings are vital for the SPM to function well) will be super common and cheap, I have good alie sources for bulk-cheap bearings but even if that store dies they'll still be skate bearings and those will still be everywhere. There is no 3d printed substitute for bearings (and I have a background in industrial 3D printing, I've played with every tech out there), the closest you'll get is a smooth metal rod and a hole in the 3D print (bonus points if you use the rod to melt the hole to be a precise fit), with no non-printed hardware the best you'll get is printed rod (ideally high resolution resin/SLA, SLS/MJF/DLM second choice behind that) going into a printed hole - no 3d printing tech produces rolling features well enough to do a ball or roller bearing. That said, I'll try and make a variant with as little hardware as possible too

I started out as a broke maker/tinkerer (now I'm an older, better equipped, broke maker/tinkerer 😅)so I sympathise with the desire to make everything on the 3D printer but there really is no substitute for bearings (note a smooth metal shaft in a hole is a type of bearing, called a 'plain bearing', for most of the industrial revolution that's the only bearing there was... but it needs a very smooth metal shaft to work). Especially with this crazy mechanism, due to its nature it needs extremely low friction on the pivots or everything distorts and locks up (eg if you used a 3d printed rod in a 3d printed hole it'd catch and jam). Don't worry though, I'll make the open source version as cheap and easy to source as possible.

This is called a 3-axis goniometer. They've been used for decades in crystallography and electron microscopy. They're typically constructed like the second setup. This is a much more compact design that could potentially lower costs and allow for greater instrumentation around the manipulator. The trick would be "teaching" the motor controllers to account for and utilize the parasitic motion.

@makebreakrepair

Ай бұрын

Half the battle is knowing what something is called ;) I had found 2 axis goniometer stages (not cheap, even from china) though they (or at least the ones I've found) all lacked the ability to adjust the work up to the center of rotation - though a small Z stage on top with your work holding attached to it would solve that. They were all still very limiting for what I wanted though (the SPM has similar limitations mind you) in that you can't look at anything longer than the center of rotation (usually 60mm above the surface for the ones I found) eg an endmill. The polar manipulator I showed also exists (and can be made purely from camera accessories bolted together, though that's a few hundred dollars of parts) though I don't know what one would be called in microscopy/industry terms. There's still a reason for the polar manipulator project to exist in that what is out there (I may be wrong, feel free to send me links etc) is an order of magnitude more precise and more expensive than needed for the kinds of low-magnification, inspection style microscopy I have in mind - If we can make one out of 3d prints, two steel rods, a bolt and some bearings then it becomes a $30 tool that anyone can make. Similarly, making one that uses off-the-shelf semi-precision elements for a more serious tool (ie somewhere in the region of $200 of parts? tbd) also bridges a gap - there's no (similar disclaimer, send links if you know of some) medium-precision entry-level microscopy tool for this job, anything I found costs double what my pretty decent digital microscope did. But yeah, 2 axis gonio stages have been in my aliexpress cart for months, could never quite justify the $450 or so but they're damn cool.

@johnmiracle7740

Oh yeah, what you're developing here is in a completely different category of precision/cost. My experience is in materials science with ultra precise scientific tools. The X-ray diffractometer that I use cost ~$500k, the goniometer is probably half that cost, and it's accurate to within 1/10,000° across four independent rotators. But I'm looking at reproducible positioning on the order of picometers. What you've shown here looks like it could be adapted for similar use, given precision manufacturing, and improve on the common set-up we use. I'm interested to see where you take this.

you could remove all bearings and just use magnets as the contact points for motion. This is used in delta 3d printers and its super smooth and easy. With this, the entire center hub could be taken out to make a simple change over from the er-16 a solid flat base or any other kind of holding fixture. having a lock or a simple detent to hold the position would be a good addition.

@makebreakrepair

Ай бұрын

This is the first 'alternative to bearings' suggestion I've heard that's actually viable... though can you link me examples that allow rotary motion only (eg the same motion as a bearing)? I know spherical motion is achieved with a magnet (spherical iirrc) and a ball bearing, but for these to work we'd need to constrain all motion other than one axis of rotation per joint... I haven't kept up with the delta 3d printers with magnets thing so I'm not sure if they've done that. That said, the little bearings are only 50c each in a pack of 20 so it may not be necessary.

@Entotech

Ай бұрын

@@makebreakrepair I was thinking that just the joints connecting to the center hub would be spherical, the other set of bearings on the arm would need to remain bearings for the axial constraint that the spherical magnets wouldn't have(i'm not sure if that would impact the mechanism or not). I do find the spherical magnets to be surprisingly strong and resistance to axial displacement. Hayden arms for delta printers use a high carbon steel ball with a machined delrin cup and a strong magnet at the base of the cup to keep the ball seated. My guess is that pla would hold up well enough to have the socket integrated into the arm with a small hole for a magnet to be glued in place, then the other side of the joint would just need to hold a steel ball and its easy to find them already with threads for a screw or threaded portion to be inserted. Bearings are probably the easier and more robust option but who doesn't love magnets if it is only a light duty positioning device?

That second version is exactly like a gimbal mount for a telephoto lens! The lens gimbal allows the screw mount to be moved away from the vertical pivot, to allow for various diameter lenses, and the vertical "fixed support" has an offset base with a rotating part. The whole thing allows an almost arbitrary size lens to be mounted so that it is balanced around the front to back rotation, and the horizontal center is also centered on the pivot...in your use case, you look to center the point of interest on both the horizontal rotation, yaw, and the front to back rotation, pitch. I installed Belleville spring washers on the clamping screws, to allow more control of the friction on the pitch and yaw axes.

The hardware design is basically finished and I am currently working on electronics, kinematics and programming. I really want to see it perform programmed paths like sinusoidal swings, ellipses and whatever can be imagined. One final thing, to adjust your height you could use some sort of screw along the main axis, instead of the slider. This way, the design will still be symmetrical and the slider not in the way, when you tilt it. To secure the set height, you would just need a counter nut.

I have no idea why the algorithm gave it any attention) and got more views than the incredible project that inspired it. (For anyone else reading this: neither swanschilling or myself invented the SPM, it's been around for decades, swanschilling made a well documented, 3d printable, motorised (with full IK!) one that inspired me to make one) I saw an SPM somewhere else on youtube (can't remember which, was ages ago now), realised it would work for the microscopy task, then while searching for a printable one I found yours. I didn't have any of the bearings etc you had on hand but your vids helped me understand that designing one is fairly straightforward (axis of all bearings meet at a point) so I knocked one up. Your project is damn impressive and you've put a lot of work into your videos, anyone looking for a motorised version I send straight to you because you've basically made a fully fleshed out product free for people to make. Also, IK and motion sim in Unity? I'd love a tutorial vid on how you set that up (or some resources you can point me to?) I'm super impressed...

I teach machining - wanting a better way to look at endmills under a macro camera / microscope was what brought me to your previous video. That should answer to what my needs are in a second design. I woulf go for simple and functional every time. However, if it has more "wow factor" and helps maintain interest... maybe the wacky cool arms version needs a little more design attention?

@@makebreakrepair I watched the new new video as soon as the notification popped. I'm looking forward to looking at the CAD for the polar manipulator... might have to make a precision machined version... air bearings, because why not? Thank you for sharing all your hard work.

The parasitic motion jumped out at me too, even from a distance... My initial thought was that maybe you could extend the inner section with a handle for manipulation. Just run the handle right off of one of the triangular spokes, lifting it a bit for clearance. You would be driving the vertical bearings in reverse, so it would probably add a little resistance, but since everything's already so smooth it might not be an issue.

I agree with the commenters who say functional over pretty. The Mk I is a fascinating thing and why I clicked on your video in the first place. A more practical version will be much better.

My use case is image stacking on something like a small butterfly wing which has to be precisely positioned perpendicularly to the lens, hence a holder that can move in more dimensions than the macro rail version would be better, but something that can be locked solidly in place without much vibration transmission is also helpful. Your suggestion about taping something in place on the last video's discussion doesn't really fulfill that for me: I would like to be able to lock and unlock it with assurance that it won't shift while locking down or come loose afterward, and I would prefer something like that red twist knob that locks smoothly, reliably, and without much thought. Imagine doing this for several hours straight and I think you'll get what I mean. Thank you for these posts--I do find the ideas inspiring and look forward to seeing the next one.

I am interested in using this for micrometeorite imaging. Micrometeorites are exceptionally small- typically between 100 and 400 microns ( 0.1- 0.4mm) in diameter. I use a microscope to take stacked images- often well above 1000x- and then process the stack into one image. I've been looking for a way to manipulate the grain so that I can image multiple sides efficiently- and then stitch the images together for a 3D model. I'm not exactly sure how this would work- but it seems like this device might be a way forward. So yes- I'd be potentially interested in the files.

Based on your comment (and a few others that are similar) I think I'll add the ability to motorise/control/automate the polar variant (both the free and the rugged one), but I won't make a motorised SPM as there's already an excellent project that is doing that better than I could, check out @swannschilling474's channel, their project lends itself well to automation and can be printed now kzread.info/dash/bejne/qIKKlK6epM7Mdco.html

For microscopy (outside of high magnification etc, where you need expensive positioning systems from the start) it's not really an issue as you're more interested in vibration damping (ie the subject shouldn't shake while you're looking at it) and that any sag due to gravity is consistent and smooth (ie when you go from subject -45 to +45degrees the subject shouldn't sag out of frame suddenly when the load changes direction). I'll have an update video soon but I've already printed and tested a polar variant under the microscope and it's stable enough for some decently high magnification :) (and before the '3d print everything, even the bearings' brigade arrives: that's only possible with actual bearings ;)

That's an interesting project.... Are you familiar with 6dof cad 'mice' (3dconnexion space mouse and similar)?

If you take that concept, and add electro magnets in strategic places (which will likely mean not using hall sensors for position....) you could give a sense of force feedback, at least for XYZ translations, not sure how you'd do rotation force feedback though. Another idea: take whatever works for existing 3dof (roll,pitch,yaw) force feedback joysticks, then mount that on a small xy stage with opposing pairs of pull solenoids (ie the type where their default state is out and they retract under power) attached in X and y. The springs of the solenoids will passively self center the joystick in the stage and could provide the force feedback under power. That'd get you 3 rotational and 2 translational force feedback axis, adding z gets tricky.... Just a random thought though, I'd be curious to see what you come up with if you make it

I ended up deciding I'd just make both available for everyone (along with design files available so people can modify it easily to suit their needs) 😅 I've just uploaded the latest update vid, I've put a lot of work into making it accessible for everyone, files available very soon and I got the costs down to $10 of parts: $10 SPM kzread.info/dash/bejne/dqWeo62mnZCserQ.html

look like fishing reel 😅

Why not use a “spherical/ball vise”. A sphere with a vise on top that sits in a little conical cup.

I have a ball vise, the issue is the center of rotation is inside the ball, ie tilt the ball and the object moves out of view - not an issue for engraving etc but doesn't work for microscopy or similar. If you're suggesting making a hollow ball vise with the work holding in the center of rotation then... that's an interesting thought, though making a smooth, large sphere isn't easy (smooth enough for microscopy at least). If i've misunderstood your comment though please elaborate, the comments section has been full of interesting ideas.

Any chance of getting your STL files please I will adapt to print in place on a statasys j750 and re share back to you .robb Barrett Sainsbury’s wellcome centre

I'm working on the design of both versions at the moment, I'll update everyone soon. There will be open source, 3d printable versions (don't worry, I'll release CAD data as well as STLs) of both styles for people to adjust to suit their needs

Your last video did not get 500,000 views for being practical :-) Make the weird one.

with your polar manipulator you basically just reinvented a nodal head, thats boring. what about a version of the spherical that can be locked in position? then it would be a great work holding tool. the spherical design would allow a bolt to be pressed against a spherical surface on the moveable part.

can i move in with you i think im in love
