I would love to see the filament maker in action!
Yes, seems odd.
I am surprised he still has it! LOL.
Would be fun
Very interesting, please show it to us.
I second that :-) even if it didn't work that well it is interesting. I would like to make my own filament extruder one day and hearing about potential issues with one is very valuable.
Oh, one thing I guess I should mention: The sensor has a FAULT output (same as the LED), which is programmed to turn on when it detects errors like the filament being outside of the expected diameter range. So with that output, it can be directly used as a filament runout sensor as well, even without firmware support for the InFiDEL's measuring output!
And yes, the pins and grub screw I used in the build were temporary stand-ins as the proper parts hadn't arrived yet 😅
Oh good timing, I have issues with my filament sensors and was looking at a replacement. Pity I only have some of the parts on hand, no dowels - order time.
Btw your youimagine design link doesnt work!
Or potentially a sensor that detects unexpected sudden bulges in filament diameter, as well. Prevent clogs before they happen...
This is great! Thanks for putting this out in the wild, Tom. Have you/are there plans to cover integration with the firmware on the printer controllers?
Ha! I was about to ask if there was a way to use it for that. Guess I'll put that thing in my DIY queue now. Might be a nice testing ground for my PineCil as well. Thanks for making this design available, very much appreciated
This type of community driven innovation is exactly what makes the 3D printing community so great.
Thanks so much for your effort Tom 🙌 as always, it’s highly appreciate it!
It’s a lot of work behind all iterations and I love how it came out :)
great project thomas! and yes, ofc i want a video on your filament extruder!
11:50 THIS is the reason i love you. Seriously dude, thank you for everything. Best 3d printing channel together with cnc kitchen as being the more analytic half.
Great job as always!
i wish you actually tested this on a printer with cheap filament. I wanna know if it makes a different
if the filament is too thick it will get stuck in your extruder tube leading to failed print or maybe worse
@@alf3071 Yes, this is a really good application example. You could use very cheap filament with this sensor and the sensor tells the machine when the filament is too thick and stops automatically. Furthermore, this sensor would serve as a filament runout sensor. Thus it would be a multifunction filament monitoring sensor.
THANK YOU! This is a nice step forward. I'm excited to see the open source community run with it!
you get a like for that pained abbreviation, love it!
I love the debugging and the programming that you kinda skimmed over. Great work
Awesome work as always Tom, a very interesting project. Also very apreciative that you open source your work.
Thanks for iterating it useful and releasing the design. It's one of those things that I've never gotten around to building from scratch.
I love that you are just sharing this! Thanks and great job Thomas!
Thank you for this, Amazing work toward the betterment of printing and the open source community. Hats off to you!
I hope to see both firmware support and preassembled modules become available, it would be nice to have and make inconsistent filaments more useable, thanks for the design Tom!
Thanks Thomas, for such a wonderful gift.
Exactly the kind of things I like to see, Thank You Tom!
I hope this inspires more development.
You always keep it classy Tom.
Be proud you are one of the best channels out here.
I learned a lot from you.
Great video and love that you're making this all free. Definite thumbs up for the cut away too!
Tom, this is amazing! I aim to know enough to integrate this on a machine of mine one day. Your university project and other DIY solutions like the PETbot are inspiring and would be great to pair with homebrew filament production/recycling!
Agreed, evolving your design with a 3d printer is awesome. I just went through 5 revisions on a new CF/PEKK extruder design and I'm finally happy
Excellent engineering! This answered all of the questions I had about the sensor from the diameter measurement video.
I would like to see your take on an extruder.
DIY filament (recycling)? Yes please! Sign me up!
Well, here's another data piece that Stefan can start including in his filament strength tests. "Was the filament over/under sized during the printing of each test part?" I love the tinkering/constant improvement in this hobby. Thanks for giving us another tool in our toolbox!
I'd love for you to consider redoing the filament maker in a updated 2021 video, using the knowledge you've gained since building it, the things you'd change, the tricks to make it cheaper. Kinda like you went over with the Infidel sensor.
This is a great contribution. Thank you Tom 💚🙏
what i like about you is that you care about us printers. but all work deserve money, i hope if some 3d printer manufacturer takes you idea and design that you'll get paid!
I would love to see more on filament extrusion. Great video, thanks for sharing
I enjoyed seeing the process, as well as a very nice looking sensor and housing!
This is a very cool idea! Thanks for putting in the effort to get this out in the wild.
Yes it would be great to have a video on a filament extruder up-to-date!
Cool project. Thank you for sharing it with community. I hope Marlin and other firmwares will get support of it.
This is awesome, as always thanks for your contributions to the 3d printing community.
I hope now the duet guys will show a little interest in this feature, in the past they weren't interested when I requested it.
Excellent video and thank you for open sourcing the project
Thank you Thomas! You're very generous!
This is awesome! Let's see it in action!
Also, I'd love you to show us your old filament extruder.
Thanks, this just gave me the idea how to make a belt tension sensor to sync the tension on the 2 corexy belts!
Need to see filament extruder working, it looks like it took more filament to make it than it ever produced 😁.
Fantastic work on sensor, will be pottering around with the idea this weekend, thanks for all your hard work.
That printed cutaway is sick!
Yes, that filament maker looks super cool
I'm sitting here _thinking_ of CADding up stuff like furniture I need to revamp my living space (because my time is mostly taken up by my day job that I actually need to pay them bills and sleeping/gaming to recover from said day job), and Tom here is actually making his ideas happen. Good times.
This is awesome and thank you so much for making it opensource, I am going to make the sensor and add it to my printer.
Very nice design! Great job, thanks for such usefull device.
It would be super to see the filament maker working!
Very cool! It gives me some ideas to even shrink the device but using a sop23 hall effect sensor on the actual board. Btw: I highly recommend you to look at the «new» Attiny series like 202, 402, 1604/1614 and upwards, based on your memory needs, and functionality. They are cheap and easy to program(only one pin - UPDI) I just love them!
Klipper already has support for a filament width sensor that changes the extrusion multiplier.
and you need no electronics at all, just two hall sensors (to cancel noise)
YES! PLEASE do more videos about your extrusion system. We need more leaders to follow for our own extruders! :)
With such a great invention and video I couldn't stay unsubscribed any longer. Thanks !
Awesome! You made it really compact. Looking forward to have it supported in Marlin. Would be nice to have measurements on 2 axes even though the filament is usually pretty round. I tried designing something similar but your idea and implementation are 1000X better than mine haha. Congrats!
Measure it from one axis, and check for a jam with the other axis. Then the wheels make an "X" and its still compact
Now the qidi q1 pro has a haul effect senor. Thanks for the video!
Great work mate and nice use of microcontroller
Should do a video of Klippers filamenr hall effect support.
It is even cheaper and because of the differential setup, it reads the magnet more accurate.
Worth a try!
Love your videos!
Nice projet !
Thanks for making it open source!
True maker philosophy!
This is a very cool device Tom! I really like the use of the hall-effect sensor and magnet, very clever. I will probably make one at some point but I don't think I really need one. I'd love to see a video about your filament extruder, it looks really interesting and I was thinking about designing one to make custom filaments. I don't the name but I recently saw a device that cuts filaments and joins them together so they look almost like multi-core cable, maybe try building one of those. Thanks for the brilliant video! 💙💛🧡
Yes PLEASE cover that filament extruded setup!
Totally would love to see you go over your filament extruder
Very polished. Impressive.
this is amazing! more of these please.
Great presentation, again Thomas!
Great instrument for diameter measurement while extruding.
A simple no-filament sensor with mechanical end stop switch would do its job for printing, cost less efforts in engineering, and parts, but would be less smart and versatile.
I' curious, what comes next...
Nice work! And with prices of filament going up (especially non-PLA) an extruder would be a welcome re-visit
Thank you Tom, great topic. Nice work.
The best method maybe the contactless way, but man you did a good job!
This is a great idea and project! Some (hopefully helpful) critisism: If I'm not missing something, your sensor only provides the intended information under the assumption that the filament is perfectly round. It measures the diameter at a specific point, but not if the diameter is consistent. So actually you can not transform this into information about adaptation of the flow factor. You mentioned that better quality filaments are usually not oval - but imo they also should have a consistent diameter. I think this is idea has potentially higher impact for cheaper filament and to be able to compensate tolerances better.
Brilliant. Thank you for this contribution.
I was literally thinking about this a few days ago! Cool to see that it is a thing
I am trying to diy a filament extruder called the petpull2. I would like to advance the design a bit with this diameter sensor. Thank you sooooo much for this contribution!!!!
Thanks for this project.
Definitely want to see more on the filament maker
That filament maker looks nice, would Love too see it revised! :)
Pretty darn neat. Nice and simple.
I would like it if you covered the filament extruder in more detail in a future video. Thank you for all that you do.
Combining this and vibration correction has the potential to produce some seriously clean prints.
I am watching already quite a while your projects and thought it is now time to leave a sub 👍
Great content, interesting to watch and listen. Greetings from Bavaria 😉
That is a nice design - thanks!
totally solved the problem of at home filament making so if its used in the extrusion and the print process pulling through an oversize nozzle seems to be the most effective but only see the laser sensors on expensive extruders
Love this project, we'll done.
Future iterations probably would be to measure 2 or 3 diameter measurements, and if that works out people can make a very own average quality extruder and filament and stil get good quality prints making filament cost and selection phenomenally cheaper.
Great work, thanks for sharing!!
Great work as always , thanks !
This is a good design and your ideal of using a V-slot bearing is a good idea as well.
Just to build on the idea a bit, using the V-Slot bearing on the moving arm of the sensor and then using a wheel with a bit more grip on the other wheel with a slotted disk and a photo interrupter would allow for the speed of movement or distance moved through to be measured.
This combined with the filament diameter could then not only detect the diameter of the filament but also filament out (can already do this :-) ) but also if the filament jambs of breaks past the sensor.
Just a thought. :-)
Keep up the good work
Ray
Hey, pretty slick! I'll have to pick up some of those parts... And get back to my Replicator 2x Marlin port 🤦
I am impressed. Can you tell us something about the accuracy of the measurement?
Awesome work!! Many thanks!
I don’t have a printer yet but this is super cool. Well done!
Would love to see this as well as a filament runout/movement sensor all incorporated into one unit.
Awesome build!
I'm building a new toolhead for my printer. And after seeing this, I think this
would be an awesome mod to be integrated into the voron afterburner.
Time to build one of these!
YES! cover the filament maker
Hey, good call on making this. I was thinking of making one too. I don’t think a algorithm would be too hard to create for printing use.
Thanks for all your great videos.
Do you have a link to those V 623 bearings ?
Yes please cover the filament extruder maker thing I've been dying to soon if there's a doable homebrew way to recycle my pla
Wow amazing, thanks for sharing!
This is great, I would not expect HAL to be that precise but your prev video on the subject cleared the suspicions. Now think about 1Wire protocol, 1Wire can run on long cables nicely, it is pretty stable and is for e.g. used for hvac, fire and similar sensor installations... I2C is terrible on cables especially around noise generators like the extruder motor... look just how many issues with prusa laser sensor board that's on i2c and how for e.g. same sensor from duet that grabs the i2c from sensor with attiny on board next to sensor and sends data to mb via 1wire type signal works without any issues (ignoring issues that sensor can't work with some filaments)
Thank you! Note my problems are order of magnitude higher, that it a tenstion measurement device for binding or missing filament.
Awsome work :) , I start ordering components and pcb to build 10 units. I just need to add an encoder wheel and some electronic to this design to allow the sensor detecting clogged nozzle too. As 'im priniting at 233mm/s on a little slinging bed printer I can't add weight to the printing head and will use ptfe tube to link it to the extruder with a known distance.
Yes please make a video about the filament extruder
Well done. Excellent video.
Heckin awesome video like usual
That's a very cool diameter sensor, I would love if I could get a sensor like this for filament out run detections 🤗.
Im total beginner and still waiting for my first flsun q5 to start with.
I was just called that on site the other day. How conveniently personal :p
Oops! Never again ☺️☺️☺️☺️☺️
