- Hey! its been a while! Lots of things going on with my projects.
Today I am testing the awesome Teknic ClearPath servo motors as an alternative to the stepper motors for the HevORT HeavyDuty XY gantry. This will open up a lot more possibilities for the HevORT product family.
In order to use and exploit some of the potential from the ClearPath the Heavy Duty 9mm and 12mm belt versions of the HevORT XY gantry have been released last month. Have a look:

The only hotend I can immagine to keep up with those printspeeds would be an aluminium block with a blowtorch attached to it!
Of course matching material flow with this speed is going to be a challenge. But just imagine for a second having instantaneous travel moves and enough accel and jerk to reach greater speed on tiny moves. Just these two thing will make a hell of a difference on print time.
On top of that, you'd have to have a small air conditioner beside the printer pumping 1deg air at the print surface.

It’s fascinating to watch you push the boundaries I’m sure many, like me, learn so much.
I was thinking the same, but with adding linear encoders at the carriage and closing the loop there. But this is a great build and it looks very well put together. Thanks for sharing the amazing results!
You definitely got me subscribed! I cannot wait for the results, and I really hope it will work!
impressive, well done! 👌😎 waiting to buy one
make one yourself!
Impressive results with FeedBack!!
Thanks for shairng :-)
It is amazing, really like the way you think outside the box. That bed leveling is out of this world. Super expensive though. but I think i wait the servos out for a bit . I am going to build a HT, I guess always can upgrade to HD easily on a later date. Great Job mate
Great work. Not only that, but great investigative work into 3D printer printing speeds.
Yesterday I was printing some 90deg bracing brackets for one of my printers. I have also just migrated over my slicing from S3D to PrusaSlicer. So I'm still getting used to the expert settings. I accidentally typed in 544mms for support speed. I wasn't printing supports but I was printing a brim.
At 220d, my hot end motor clicked like crazy, but it printed the brim smoothly.
yeah, that clicking sound! I can relate to that :)
I ran Clearpath servos on my first motion platform. I'm quite a fan of their products. I think I may be going this route for my Hevort build >:)
Love your videos and how you are pushing what is physically possible with this technology. Please keep it up we enjoy your content. Also please finish this machine and sell us a kit or something...🤣
Thank you! means a lot! :) Yeah... Kits would be nice. Need to move on that!
Tune this beast and sign me up for a kit. I am sure many people will feel the same once they see your results. Once dialed get it printing nylon/Carbon fiber... My god this would be a dream machine. Good luck.
Hell yeah !! I had wet dreams about clearpaths on a printer !
Damn this is insane, came here from the 800mm/s attempt video and of course that wasn't enough eh! At one point the slicers will probably have to consider the plastic's inertia when being laid down, jeez, I can imagine that if the extrusion isn't right on point it would probably fling molten plastic all over. Would definitely love seeing it either doing just that or succeeding a print for sure.
Wonder what you have in mind for an extruder for this monster, like an overvolted heater? quad geared NEMA 23 extruder? Something crazy for sure, that would be cool as heck, looking forward to whatever insanity can keep up with the movement.
Those belts sure ain't no crappy random belts either, considering a normal 3D printer could barely function as a light duty CNC mill with their normal setup, no way in hell the standard issue belts would handle those forces.
wow, im excited to see this monster printing
It is very interesting to observe the development of the project and the technical solutions. I'm always on the rise after your videos. I am interested to see in more detail which servos are used and how their management is organized.
wow and its still sooo nice and quiet!
Was thinking what an odrive printer could look like, i think this is it !! Great job, i'm waiting to see more of your content !
A couple more things to do on my side, and I will be back at Servo testing soon.
Well done, Sir! You probably will have limits for deposition of plastic before get to the limit of the motors. Looking foward to see it printing.
Hello,
I, who lives lost in the French Alps, will watch your videos with great interest.
I'm thinking of installing this type of engine on a large format printer.
I hope you will continue to give us more details and tips.
Thank you for sharing.
Un beau bonjour à toi du Québec cher cousin! :)
I like where this is going! Keep up the good work! This is the kind of innovation the industry needs. I'm wondering if being able to drive a bigger extruder without missing steps would open the possibilities of more extruder innovation. I'm thinking some kind of valved hotend that can control the flow of plastic more precisely to take advantage of those enormous speeds.
a new extruder philosophy would definately enable us to harvest the benefits from servos for sure. But for now, I will content myself of having faster tny moves due to strong accel and jerk and almost instantaneous travel moves. This will still make a huge difference on print time. Next milestone is material viscosity and cooling.
An ideal candidate for Nova hotend. Doubt Volcano can handle such abuse! Excellent work!
SuperVolcano could. They are expensive though for the special nozzle/block/cartridge. But they push around 150w.
Damn looking nice!!
I've been wondering exactly this for a long time! Thank you for this! Never could afford servos to test it, so i haven't.. but i think conventional hotend could never keep up with that, needs to be force fed with a hopper that can really push stuff out, and in order for the layers to cool down fast enough, rather colder temps than hotter
Thanks for the comment. Yes, these motors are going to open many doors. Some doors currently lead to the unknown. A lot of experimentation is to the agenda for the nex couple of months. One thing for sure, the HevORT HD XY gantry can take some serious abuse! Been pushing the servos to 80K acceleration and 60K jerk at 1200mm/s for 30 minutes. No sign of fatigue or damage so far. belt tension is maintained.
@@MirageC and with a servo to drive a hopper against it's will to push enough plastic, i'll come for a visit to build a 2x2x6 meter printer 😁
@@Tarex_ We will need to re-think a few things for such a size though ;)
the grab the belt trick got my sub hands down fingers attached !
WOW! Realy fast!
Well, filament can be preheated beforehand so hotend don't have to melt it from room temperature, but from my perspective servos are good for dramatic increase in Z resolution at the same timeframe
You've become my inspiration on printer upgrades. Going to try implementing your designs on my core xy, the triple z auto compensation is amazing! If you're looking on what to put on your beastly motion system, why not go for toolchanging (ASMBL) and add a cnc spindle? IDEX ASMBL toolchanging if you feel ambitious. You're going to want to protect those hiwin rails and ball screws though, the sound of a chip getting stuck in one of those and making a nasty grinding sound, makes me shudder.
Yes tool changer is in discussion within the HevORT's community. Will be looking at that during the summer. The printer frame from this video has a longer Y axis that provides space provision at the back for the tools. And yes, some sort of boots and brushes would need to be installed to avoid debris.
@@MirageC I am researching my next project and had decided another corexy but was definitely wanting it to support IDEX and tool changing. I will be watching closely and appreciate all that you do for the community
This looks crazy ahah, awesome job
Thank you :)
Not only will you need a crazy hot end and most likely another Servo for the extruder but an equally crazy part cooling setup for that speed, Really cool machine nevertheless.
Great work on this ongoing project!!! Are these the ClearPath-SD or ClearPath-SC?
What I am thinking is printing a screw feed extruder raw plastic pellet hotend and a heavy cast iron frame like those super fast smt machines. 😂.
Good job bro. Keep creating 💪
That's cool. I have already made and used my own design 3D printer using Panasonic servo motors. As a tip, it is important to increase the belt tension strongly for quick response. After that, the bearings of the idler become unbearable. I use the idler by removing the existing bearings and attaching two bearing outside like a sandwich. Good luck.
Thanks for the advice, I will be monitoring those tiny bearings closely :) I run 12mm belt, they seem to be handling the load fine as of now.
i need a tip please,can you give a help what the card you used to control 3d printer with panasonic servo motor. Card Bigtreetech SKR Mini E3 V2.0 it's okay to using.
I like the JMC H57 180w servos at 3000 rpm spin ball screws fast and smooth. At $85.00 each for AC servos is great.
Hi I'm very impressed by your motion system! Can you give me more details on wich comonents did you use. How did you do the pid tuning for the position control? Which interface did you use (step / direction or somthing more intelligent :D ? Im planning on using jmc servos
I am harvesting the Step and Direction signal that was intended for the Duex5 expansion board using a DuetBreakOutboard. The Servos were tuned using their internal controller and the proprietary software from Teknic (manufacturer of these ClearPath servos)
Amazing work and fantastic video! Which version of the XY are you using 9mmHd or 12mmHD? I am working on purchasing parts using your build. I had planned on going with 9mm belt drive and nema17's to start. Wondering if there is much of a difference in drive weight between the 6mmSTD and the 9mmHD set.
I am attempting to give myself some room to grow on tuning the printer for faster speeds. Do you think performance will be lost using nema17's and 9mm or 12mm belt drive? My best guess is it would reduce belt stretching at higher speeds. Trying to future proof my build a bit, wondering if i should go bigger and use the 12mm belts?
Tough call, even for me to say at this point. 12 mm like I have feels great. Definitely more friction than a 6mm setup, but very solid. My current position on the question is that if you intend to use super heavy X carriage, or going bigger than 500mm square, go 12mm. If not 9mm will probably be your best bet. But once again, this is all new territory for me as well. The Think, Design, Try, Correct circle is in the Try quadrant for this gantry ;) Correct quadrant looks smaller and smaller every day though ;)
Which kind of linear rails are you using? Do you think cheap Hiwin clones will do for a CR10S project well? Thank you for your videos. Your HevORT project is very inspiring!
The 800mm/s video was done on Genuine Hiwin rails. This new frame with the clear paths is using clones. So far so good, but print quality needs to be validated.
I always wanted to see this. My extra large format machine moves a printhead that is over 1.5 kilograms and with TMC drivers and Nema23 motors I can't get over 160 mm/s speeds othervise I get missed steps (shifted layers). Been looking for a servo driven printer build like yours. Keep up the good work!
Thank you! Yes, nema 23 have good torque but poor speed due to their high inductance.
I wonder if you are getting to the limit of the belt capabilities for heat and flex?
Assuming there is no flex, is layer adhesion affected by faster speeds? As a thought experiment, If I had a frame carved out of solid diamond with motors to match, could I expect to have good layer adhesion?
i love this machine
By mistake I have 32 closed loop servo motors...but couldn't figure out if I can Run them on a Standard 3d printer Board... What elctronics drive your motors? I have a half built Delta for our makerspace, that would be great I think as a showpiece and also we're building up a Lowrider2 for the makerspace 🤔
The proof is in actual prints. I did ClearPath motors on a larger 3d printer four years ago and couldn't get it to not induce banding in the print. I currently just run steppers on that printer and it's been fine. I also run a 5kg pellet extruder off of it. I wish the CP motors gave me better print quality as I really appreciated their silence.
Yes Jeff, I have been reading about your experience on various posts. I will give them a try and see if Teknic is ready to support if I cant get proper quality. Just a quick question. when you tuned your CPs, what did you do with the other servo? I simply enabled it so it would be "locked" and then tuned the other motor. I did not think of any better to represent the CoreXY environment. I am using the 800 count per rev version. (CPM SDSK2321S - RQN)
@@MirageC I ran a crossing gantry machine as I felt CoreXY was too new. But I too would guess “locked” is probably the best bet while tuning the other motor.
Hi @@JeffDM
,
I’m an applications engineer at Teknic and I came across your comment. The banding you describe can be caused by a number of factors, most of which can be resolved. (We have a number of OEM customers that successfully use ClearPath motors on 3D printers, so you can be confident that there is nothing fundamental about this application that would preclude using a high quality servo and getting good motion performance with no banding.)
It’s common to see banding (or similar artifacts) occur when there is a mechanical issue, but since you mentioned that your stepper motors are working well on your machine, I think the odds are pretty good that there’s nothing mechanically wrong with your system. (This assumes that the move speeds and accelerations were the same in both cases, because higher accelerations, in particular, can illuminate weaknesses in mechanical systems that wouldn’t be seen at lower accelerations.)
This means the problem you experienced was likely caused by either suboptimal ClearPath tuning (i.e. the Auto-Tuner didn’t give you ideal results for some reason) or a ClearPath motor set-up/configuration issue.
If you still have your ClearPath motors and the time to run them again, we would be happy to arrange a time for one of our engineers to remotely dial into your machine and make sure that you get your machine working well.
If you’d like to do so, please give us a call at 585-784-7454 or fill out a "contact request" on our website to schedule a session: www.teknic.com/contact/.

Dude. You're the bomb.
Maybe 2 or 3 volcano heating blocks with liquid cooling on top one would allow melting fast enough without jamming... not even sure.
I don't think the limit would be the extruder motor ... you'd need a constant push, from the back, crazy heating speed and a kind of control valve at the end, I guess.
DOABLE !
Somebody just mentioned something I have never though of or seen. See reply from R Dyer: th-cam.com/video/m6DoKoESPdg/w-d-xo.html&lc=UgyOb1T65m1eDzyLatZ4AaABAg.9GBp85iJPer9GCIrwLiyRs
Yoi dont need liquid cooking to print fast :) you need it to pront slow or in chamber.
This is really cool! The challenge I see isn't sufficient plastic flow, it's the ability to turn the flow on and off quickly and at the proper time. Seems like these kinds of speeds and acceleration would be fine for creating things in 'vase mode', but much harder for the more traditional printing that we're used to.
I think you're going to cause an entire change in extruder philosophy and design where they may not be able to rely on pushing and retracting of the filament to turn the flow on and off, but require pressurizing and physical valving of the flow - like a fuel injector for internal combustion engines.
Also I think it will require software improvements as well. It seems that you would need to do some sort of predictive flow control that would anticipate the need for plastic ahead of the move. Back to the fuel injection technology... it would be like advancing and retarding the timing.
I think this may qualify as a 'disruptive technology' for 3D printing. Very interesting...
Both marlin and klipper has predictive flow control.
@@traniel123456789 I've only worked with Marlin to change configuration values of my printers. I definitely don't know the internal intricacies of the firmware. Does it have predictive flow control that can be adjusted for each move and extrusion, or just global variables for things such as retraction length and speed?
@@rdyer8764 i think Mr Vestøl referred to linear pressure advance, right?
@@certified-forklifter I am not exactly sure as to what he was referring, and I don't wish to put words in his mouth. But since you guys posted your replies I started looking around a bit, and I found some excellent info and TH-cam videos on linear and pressure advance. I believe the correct term in Marlin is Linear Advance and in Klipper it's Pressure Advance, but I could be wrong about that. Regardless of the exact name, this feature appears to address pressure in the nozzle (which controls the rate of material extrusion). The two features attempt to compensate for the same problem - how to allow for speed changes (due to acceleration settings) at the beginning and end of an extrusion move of the print head. However, this is only part of the problem I was thinking about.
I was also thinking about what happens at the beginning and end of a move between extrusions. From what I could ascertain in my short research, I don't believe the K factor for Linear/Pressure Advance addresses this. But more importantly, I'm thinking that at these speeds, there's no way that precise starts and ends of extrusions can happen strictly by manipulating the filament with the extruder motor.
For example, if there is a very short extrusion coming up between two quick moves, can the extruder motor increase and then decrease nozzle pressure precisely enough to put out the melted filament in almost a 'drive-by' manner with the rapid speeds and high jerks shown in this video? I'm wondering if a better method would to be to maintain a near-constant pressure in the nozzle and controlling the exact extrusion time and duration with a valve.
Also, existing nozzles couldn't have too much pressure without molten filament backing up into the heat break, so we would probably need new nozzle technology with pressure measurement. All this would mean more hardware (weight) in the print head, but as MirageC said, there is more than enough motor power to allow for that.
The bigger problem is that I don't think that this hardware currently exists in a small enough form factor to fit on even a HevORT printer. Again I could be wrong about that. However, if these methods could be implemented with precision, the timing issues for extrusions go away, or at least they become constant across moves and extrusions.
Thoughts???
@@rdyer8764 mmh, yeah. thank you for your research!
Did You use the Duet 3 Expansion Board 1XD to connect? If so can you show how?
What about carbon fiber square tubes instead of the aluminium ones for the moving part?
Essentium has a hotend that heats to 500c in 3s and They print Even 0.6mm at 400mms so its deff possible..
Im looking at a simular setup but just with precision ballscrews that has no play and 0.0025mm precision.
All made possible for my budget, after discvoering clearpath :)
My understanding of where the bottleneck is in speed for 3D printing is in how fast it can extrude the plastic. You can go either bigger nozzle with low resolution on the print. Or make a hot pot resorvere. Where you melt a lot of plastic in advance and then use something like a auger to extrude the plastic faster through smaller nozzle. Or use 2 heads, one with large nozzle where you print it into a ruff size and then use secondery nozzle with smaller nozzle that puts on the final top layer...
Yes, definitely, the extrusion system will be my next bottle neck. We will explore various options.
I want so much to see it printing!
ME too! I know the road will be tough to get this to print good, but at least I have one extra card in my play now with these motors :)
I wanted to know if I could potentially do servos controlled by Duet to likely a servo controller?
your servo controller will need to take Step / Dir / Enable signal type. if this is the case, then yes it would work just like it does on mine.
What motor type are you using for the X Y and what belt size? I am in the process of building a hevort and trying to work out the best drive system. The bed is 500 x 500. Apprciate your advice.
Hi Ben, those motors a test, they are ClearPath Servo Motors from Teknic. Very neat stuff but also very expensive. If you are in for a good stable configuration that will not empty your pockets too much I recommend HD9 or HD12 XY gantry (HD12 is used in this video) 9 & 12 refer to the belt with in mm. See more at www.hevort.com (Item #5 has all the data and CAD)
hi!, 1 quesiton, is posible BUy this complete printer?
thanks
The sloppy hot filament coming out of the nozzle will have some significant inertia before it cools down in situe. You'll require significant cooling at the tip and some powerful nozzle. Friction within the nozzle and filament pressure flex within the nozzle itself will become the next once you fixed that. Happy engineering ahead ;-) Nice project so far though.
Yes, agreed. I got that cooling issue somehow sorted out :) th-cam.com/video/65FVQ1jArME/w-d-xo.html
How did you wire these into the duet?
@MirageC I'm planning to do the same with my printer. How did you interface the motors to the main board? Do you just put the clearpath motors before the drivers, so it receives the step and direction signals? Or are you wiring another way?
Im still looking for this answer have you found it?
@@mikegocrazybeats depends which board you use. I used the SKR 2 which has CLS (closed loop servos) outputs. Wired the step and direction pins of the clearpath to those pins and it all just worked perfectly.
@@bobhaha Can you elaborate? Were using the BTT V1.1 Octo - becuase it has 8 Motor Ports - Our Printer has 8 Teknic Motors - Check out d3labs
@@mikegocrazybeats Its super simple, remove any installed motor drivers from the mainboard and plug your Step, Direction and Enable pins from the clearpath motor into the mainboard (where the motor driver would normally plug in). Make sure you configure the clearpath motors as step and direction mode. If you need any help, PM me.
@@bobhaha Should we still use the base driver configuration A4988? Or do we undefine the stepper driver in total?

Which extruder can push the filament and which hotend can melt the filament with this speeds?
As answered to another member: [Of course matching material flow with this speed is going to be a challenge. But just imagine for a second having instantaneous travel moves and enough accel and jerk to reach greater speed on tiny moves. Just these two thing will make a hell of a difference on print time.]
This is literally what I've been holding my build for hahaha aannnd I guess I'll get printing now 🤖...
Also @miragec these servos are most useful for X &Y , so do you plan on leaving the z leveling motors as good and cheap nema 17s?
Build plates larger than 500x500 tend to back drive the nema 17s. Either nema 23 of geared 17s are in the plannjng. Backlash from geared stepper will not be effective since the bed load is always in the same direction.
Clearpath on Z would not be logical in my mind.
Have you considered a delta for possibly a higher top speed limit?
I have been curious about them but never took the time to look into. I have heard (did not verify if true) that a heavy head could be problematic for the rods.
@@MirageC I’m looking at doing a tool changer delta that only changes the hot end and then uses a remote drive gear which traps the filament on the tool change to remove weight. I’m getting a lot of things from cnc tool changers. Thanks to your video I’ll definitely be looking into these faster motors. Great work
Which exact model of ClearPath are you using? They have quite a few! I'd be interested in this on a Duet 2 WiFi on my Delta with a Direct Drive Head/Extruder!
@Thu Nell Ⓥ Thank you very much for the info! 👍
Quite pricey! Very nice though!
I'm very curious if you can put a Zesty Nimble or Flex3drive to this speed.
Unfortunately not. I have owned 2 Nimble V1. Their gear ratio will max out NEMA 17's capacity. Especially when using strong pressure advance value. Nimble V2 and V3 have lower gearing values but will still not make the cut for this kind of printing. Making the extruder power motion remote id brilliant, unfortunately the motor used and the torsion of the cable make it not suitable for this application. I even tried with Nema 11 mounted directly on top of the nimble. Worked ok, but could not keep up.
Do you have an installation video?
Damn. Also why do your motors have couplers attached? How do you drive your belt?
Any motor should not be suffering from radial or axial loads. We usually mount the pulleys directly on the motors for small printer applications since the loads are not so great. But when using wider belt will require more tensioning force. Then adding to this the tension created by the abrupt movements themselves, this could be damageable to the motors. So I have decoupled the radial and axial loads by capturing a shaft holding the pulley between 2 bearings. Then one end of the shaft is driven by the motor through a spider coupling. You can see a section image of a motor mount here: github.com/MirageC79/HevORT/blob/master/HD/HD_YCarriage%20v74section.png?raw=true
with such speeds you'll definitely face the problem melting sufficient plastic 😊
At least now I have the luxury to install ANY size of extruder or heater block :)
You should do a benchy on that machine. Id love to compare it to my lastest prototype
Yes! I need to get back on the developement of this machine.
The speed is not difficult to achieve. There are tons of applications moves lightning speed. But as he says managing the rest of the printing operation is problem. Extrusion, cooling etc. I think, it can be used some sort of molten plastic reservoirs that pump molten plastic directly from nozzle. So, there will be no hot end but hot reservoir let's say 100ml. And that reservoir needs to be fed by external plastic source.
Hmm I think a 3dpassion.com Nova hotend would keep up with this,😎 Loving the speed
Nova Hotend in the mail! :) will let you know soon!
@@MirageC push it to the max ;)
Which model motors are these? Are they a drop in replacement for steppers, or do you need a different control board/firmware/etc?
You can see the details for the motors here: www.teknic.com/model-info/CPM-SDSK-2321S-RQN/?model_voltage=75
They are Nema 23 format so physically bigger than the common Nema17s. Than are driven using the Step/Dir/Enable signal directly from the control board MCU and converted to a 5V single neded logic. I am using a Duet2Wifi and a BreakoutBoard for external drivers to achieve the connection.
@@MirageC Please help as im trying to do the same
Fucking awesome! Ive been contemplating dabbling with this setup for a while now, it's nice to see it under operation. Under the majority of circumstances, print speeds will be constrained by the filament's material properties as I'm sure you already know but for anyone that doesn't, How Cool will it be having almost instantaneous rapid movements? Print quality will Greatly improve as you have much finer control over retraction settings and much lower hot-end dwell times. Surface artifacts and dimensional accuracy should see a pretty drastic improvement assuming the machine vibrations are being managed. Kudos !
Thank you! Yes I am fully aware of the challenges ahead, but one step at the time. :)
Could you please share how did you connect theses motors on the duet controller. Did you use COON-LCD? Or expansion header. Thank you

Ever considered magnetic levitation?
Imagine Printing with that speed.
You Probably need loads of heated airflow. Temp depending on Material. Cold enough to cool and warm enough to Not lift the Print. Like 60deg C air from two big blowers across the print
Yes, that is the plan ;) th-cam.com/video/Kyxqv4XoolI/w-d-xo.html
@@MirageC Nice, part cooling will be key. Some university a few years ago put out a video of a printer with similar speed that used a laser heated hot-end. They said the biggest speed limit was part cooling. There was also a recent 3D printer competition where the winners got the best strength by cooling the part with a blast of air just below the glass transition temperate of the plastic.
I clicked on this expecting to see smaller, cheaper servos like the MG996R. But good luck with your hot rod!
Stronk motors! Very stronk!
Use two gantries (and two extruders) and divide your printing time by two :-D
Seriously, how cool would that be? Having two extruders working on the same print at the same time
So sick. Are you using an Odrive to control the servos?

This Old Tony started 3D Printing, too. Would be amazing to see collaboration between your channels.
Unfortunately, 3mm filament gets less contact area for the same volume of material than 1.75. using current hotend technologies, i dont see how that could be beneficial for high speed printing.

No clue yet, But resonance compensation from Klipper firmware will be used. As i do it on my stepper motor printer: th-cam.com/video/ZtpQwZyuZP8/w-d-xo.html
Can you make a video how to integrate those servo motors??
Yes, working on it. I definitely want to successfully print to an acceptable level of quality before being the cause of somebody else to go servo route.
What display is that?
What would happen if both head and the heated bed are moves on a gimball mechanics? That would be a real 3d Printing IMHO as I guess....and maybe a huge speed improvement if both gimbal platform moves in sync...
I really wish these groups would migrate away from Facebook 😐 I have so many questions but my principles will not allow me to participate. Watching and waiting for a tool changer build. I can't give up multi material. IDEX is working for now. Tool changers will be the market for this machine. Too many prototypes require dissolvable supports. The speed at which this machine could change tools would be very impressive. And the bed leveling is so efficient. Loving this. Excellent work.
We have a Forum.... ;) forums.hevort.com/index.php
@@MirageC Fantastic. Reading wingnut now. Crazy build.
@@MirageC is there any immediate plans to implement a tool changer or IDEX build? Or is the main goal for now to push the speed envelope with a single extruder?
Ps: awaiting forum verification
@@mikeblocker5720 Some members are starting to draft solutions for tool changer. I would like to start looking at that myself during this winter. I am not a big Idex fan.
@@MirageC I dislike a number of things about IDEX as well. For some time it was the only reliable option for multi material printing so I have gotten use to it. Glad to hear people are working on tool change solutions for the heVort. Exciting times 🙂
nice job moving a printer.. but will it print well?
I have the same interrogation! We will find out soon ;)
hi, can you tell me the software you use for control on the tablet? thank you
It is the native web control interface from the Duet Control board that I use. I access it with Chrome installed on an Amazon Fire HD tablet: amzn.to/2L4OcO9
Hey mate, is it still possible to build the Frame out of 2040 and 2020 instead of 3030 ? its hard to get the 3030 where i live .
The official HevORT version only support 3030 as of now. One member from our community has started adapting the parts from XY gantry to 2020 profile: www.thingiverse.com/thing:4602335
Will the filament catch up with the speed ???
I am looking for suggestion on Low viscosity filaments :)
@@MirageC maybe you can figure what filament GH enterprise uses for their 2000mm/s concept printer.
New video pog
Good speed mate, but the fusion time has allways been the limitation. Alas.
As answered to another member: [Of course matching material flow with this speed is going to be a challenge. But just imagine for a second having instantaneous travel moves and enough accel and jerk to reach greater speed on tiny moves. Just these two thing will make a hell of a difference on print time.]
@@MirageC Sure the gain on travel moves can potentially reduce the printing time by 20%. Back in 2012, The reprap community have already dettermined the max fusion speed of a 1.75mm filament around 250mm.s². This is reachable with the super volcano with a mounted 0.4mm nozzle. If you wanna do faster, you must must decrease the filament diameter. Simple as that. ;)
At this speed I suspect the hotend will not be the only bottleneck, viscosity of the material and fusing with previous layers will be the challenge.
Agreed, Some High Speed PLA exist on the market, perhaps we see more in the future.
worp speed ?
Wow.. DAmmnnnnnnn what is that belt? is it normally using GT2?
is it as quiet as it seems from the published clip ?
Yes, they are super quiet. The noise in the video comes from the belts.
See how Clearpaths compare to stepper motors: th-cam.com/video/zUy89MT_Rkk/w-d-xo.html
Monster
Please do a tutorial on how to get clearpaths working with a reprap printer
Working on that ;)
@@MirageC oh that would be amazing. I want to build a custom 1m^3 corexy printer with servos. Specifically clearpaths
At some point only printing with light will be faster... Lasers! 💪🤓
Hey there, would you be willing to post your config file?
Is your printer as quiet as it sounds at these speeds? Mine is so loud even with tmc
Yes it is, Servo Motors are completely Silent. Keep in mind that there are no cooling solution yet on that test bench ;)
@Arpad Toth like the HevACS?
You should be the President of 3D printing planet.
Haha ! thanks, but I consider myself as a beginner under many aspects still. The true President of 3d printing in my opinion is Adrian Bowye. www.reprap.org/wiki/RepRap
@@MirageC Thank you for the link. I'm using ClearPath servos on a CNC project and they are awesome service included. I can't wait to see your ClearPrinter at work. Salutations from France.
Hello, do you have a parts list?
I would build myself a printer like that.
Visit www.HevORT.com :)
Hi mate.
Message from Australia.
What board are you using to implement the servo.
I'm in the process of doing a servo system.
Any advice would help.
Thanks in advance.
Could I message you or make contact please.
I did not play much with them yet... too many squirrels in my head! but you can find details on how I have set them up here: forum.duet3d.com/topic/19887/clearpath-servo-motors-testing-so-far-so-good?_=1614356929150
@@MirageC thanks again for information.
Wasn't sure to go with duet or Marlin.
Using a odrive that takes step and direction.
Trying to work out best option for printer board.
