excellent design! 👍😎
Awesome, I love the simplicity of it!
surprise surprise !!! omg this system is perfect for jamming/cutting filament...!! wow,,,you are really brilliant...I am so surprised..keep working on this field please !! and in my opinion try to add retraction when the print has been stopped, It might be perfect or maybe you already added it 🤣
Very kool device... Thanks for sharing
Pretty ingenious.
Really like your design; very clever and simple. Thanks for sharing
Glad you like it!
Nice work👍
Nobody is using a pressure/weight sensor for filament problem detections. The main variable that changes when a print fails or succeeds is the weight of the spool. The sensor doesn't even need to know how much filament is on the spool or on the print bed... all it has to do is keep comparing measured values while printing and when it detects no change for a given time window, the print stops. The printer knows how much plastic is being extruded for a given time & this info can also be used with the sensor for more advanced behavior.
This is a really cool and cleaver design! One potential annoyance is that when the filament runs out it can be time consuming to unload the left over filament between the sensor and extruder.
Simply pull on the filament back from where it enters the sensor.
@@MirageC Ah you're right, somehow I was thinking the end of the filament will have to reach the center bearing to trigger. very cool. 👍
good idea!
I have not have had luck with optical sensorers and dust
I would prefer Magnetic sensorer or ultrasound sensor (maby a Prox sensor), that is the only things that works in dusty areas
Interisting approach
THanks for sharing :-)
Wow, je viens de tomber sur ton site/youtube channel et je suis vraiment impressionné par ton design. Je cherchais une façon d'utiliser un détecteur optique pour le filament et tu viens de régler mon problème. Ceci peut être adapté à n'importe quelle imprimante 3d. Continue le bon travail c'est inspirant. Je vais probablement bâtir l'imprimante core XY éventuellement.
Wow, I just found your website and youtube channel and i'm very impressed by this design. I was looking for a way to use an optical sensor as a filament sensor and you have just solved my problem. This can be fitted to any 3d printer. Keep up the good work, this is inspiring. I will probably try to build the core XY printer eventually.
Merci Alexandre :) Oui ce détecteur fonctionne bien. J'en ai installé un sur mes deux imprimantes. Son seul défaut est qu'il est parfois difficile d'inserrer le filament bord en bord si le filament est trop courbé. Mais il ne s'agit que de le redresser et ca passe. Je songe a une version alternative utilisant une roue dentée qui créerait une pulsation lorsque le filament avance. De plus en plus de control board offre la possibilité de comparer la pulsation au débit de filament requis par l'extrudeur. Si la différence devient trop grande, il y a soit un glissement de la gear d'extrudeur, ou plus de filament du tout.
@@MirageC Ça fait du sens. Je présume que tu es du Québec. Ton anglais est très bon mais je décèle un accent comme le mien! hehe. Ou achètes-tu tes extrusions pour l'imprimante?
@@Mayalecabot Oui je suis de la grande région de Montréal :) Jachete mon extrusion chez faztek.ca
@@MirageC Est-ce que c'est juste moi ou ils ont juste de l'impérial et aucun métrique, dont les 30x30mm que nous avons besoin pour l'imprimante.
Quality.
Super comme détecteur. Bien pensé. :)
Merci! :)
Very nice. I didn’t follow your double spring arrangement. I’d like to see a diagram showing the arrangement.
Very nice. But you should really make a v2. You already have the mechanics to register difference between jam, and run out. If you could find a way to let the software register the difference, then it could tell the user. Maybe another type of sensor?
Very cool, too far in = no filament, too far out = filament jam/tangle/etc
excellent but it will not detect if the hotend is jammed right ?
Still not sure if I should build this one or the Voron 2.4.
V. Good work.. but wht if nozzle get jam.. i think yor sensor not work in this case..
This is so goooood :) I really like it
Great work. Woul be nice to have a micro version.
Thanks for the comment. Unfortunately I don’t have plan to reduce the size for a simple reason. By reducing the size while still getting enough plunger travel, the deflection of the filament would generate a lot of restriction on the extruder. Plus the filament installation would be difficult as the path would not be as straight as the natural shape of the filament.
@@MirageC i think there is room for making it more compact: not with length, that might need to go up, in fact; but with width.
What if you reduced the travel, but stiffened the springs a bit? And to prevent filament from getting broken - make a "floor" for it, lined with half (lengthwise) of a PTFE tube.
By doing that we can make the windows and the blocker only 2mm tall and shorten the fistance between it and the filament. That way it could become thinner and fit smaller printers.
Hm.. I think the basic intention is great, I am just not so sure about relying on the spring tension (if I understood that correctly) approach. Does this work with different filaments as well, like elastic filaments (that are "wet spaghetti")? Does this even trigger the "filament is here" with such filaments or are they just not stiff enough and you have to try and adjust the spring tension for every filament with the screw?
Rev 1 of the design has been used on my two printers for 3 months now. Working flawlessly for ABS, PC, Nylon, PETG, PLA, ASA using the same spring tension. TPU works good when adjusting the spring consequently. For TPE... this system is not meant for it. But for all other material it is very good. When using TPE80A for RC tires I prefer mounting the spool in straight line over the direct extruder head with no bowden. So the SpEye is being bypassed in those situations.
Great design, but I have a question. If the jam was after the sensor, for example the nozzle, would it work or is it just for before the sensor?
Same question i have.. and i think its not work.. if nozzle get jam..
I don’t think it truly works as a jam sensor. His situation is of the filament in tension between the extruder and spool when this is rarely ever the case. I should specify that the intertia and rolling resistance add tension to the filament, but it’s negligible here. Regardless, jams do not great this tension. In fact, jams STOP the feeding of filament, therefore how would even detect a jam if the extruder is not able to generate the tension needed to activate his switch.
@@justinmoritz6543 It detects filament jams not hotend clogs. For that I would put a weight or pressure sensor somewhere... either under the bed or the filament spool holder. It doesn't even need to know what the bed weighs or how much the print weighs... all it has to do is measure the weight it's at while the printer is running and compare it to previous measurement & if the weight remains unchanged for too long while it's printing, it stops the print.
I'd personally use a rotary encoder! just put a shell on the ball bearing with patterns to trigger the endstop. doesn't even need direction. that way you can detect clogs on the hotend side ttoo. and it'd be smaller. the resolution would be more than enough to detect jams after I'd say 10s? tho that's enough to grind some filament, then again you could gear it up to spin faster xD
Yes, this is my next plan.
@@MirageC 😈 The plaaaaaan
@@MirageC and ETA on this? working building your original SpEy Sensor right now. tbh, had some struggles with printing the overhangs, and figuring out the assembly but i think i got it now. i might make a video showing your design and assembly seeing as this is cheap, effective, and i couldnt find a build video
@@ParisLuHv That is correct, the overhangs from the plunger location need very good cooling and bridging settings. As for the instructions, yes that is a good idea. The rotary wheel encoder version has no ETA yet. Too much stuff on my plate now. Some people on the BLV community made a cool version of it though, you can have a look.
What's making all the noise? Also, are you able to resume the print after you put more filament in?
Yes, the borad used on this printer is a Duet Wifi from Duet3D. It has resume function after pause (user triggered of filament sensor triggered) Even power outage resume is supported. The background noise you are refering to is a Berd-Air system. made from a small air pump it delivers air to the part through a tiny tube . No fan, no big duct :)
I like the logo you put on your parts. I should make one but I can't come up with anything.
also damn those layers are gorgeous. what do you think is the main thing that gives u such a nice layer lines?
Your printer is amazing! Do you sell kits?
+1 for kits

Is this still in use?
Noice
Hi, I currently have a classic hypercube evolution 30*30*30cm. Is it possible to upgrade it to a hevort?
Yes! Of course. The initial design was made to be fitted on a 300x300 xy hypercube evolution. No printed parts are common between the 2 though. You will also need to create new upper Z rod support that sit on the side or under the mid horizontal extrusion.
@@MirageC After I'll finish my voron, this will be my hevo upgrade, any manual?

I'm concerned this approach wont work with flexible filaments?
No it wont.
@@MirageC I really like this system so spent some time thinking about it more. Correct me if I'm wrong, but abstractly it is basically a backpressure detection system? When backpressure becomes excessive, the filament buckles, tripping the sensor? Hence one possible evolution on this concept would be to measure backpressure by measuring the current consumption of the extruder stepper motor. I think in theory TMC steppers should be capable of this, since that seems to be the operating mechanism for stall-guard and sensorless homing. It'd certainly be tricky to set the right thresholds for the system to work with all types of filaments at all appropriate printing speeds, but doing it this way has the advantages of 1) requiring no new hardware and 2) preserving a tightly constrained filament path and therefore flexibles compatibility. What do you think?
Is it marline compatible ???
Yes, it is ;)
Nice, can we have the 3d Modell???

@@MirageC can you please update it? There is no hole for the second fiting
This seems like it will only work with bowden or reverse bowden setups. Any plans for retract on jam?
Not sure I am following you. What other systems than direct drive and Bowden are you referring to?
@@MirageC i think they're referring to the tubeless direct drive. Reverse bowden is cool and all, but not all extruders have it.
no sound?
there is it was my foult
I thing this is just way to complicated to really work.
Could you please stop using that pointlessly loud music on the videos ..?
