        <title>Hangprinter version 3</title>
        <description>This thread is for discussions between builders of Hangprinter version 3.

At the time of thread start, version 3.3 lives in [url=https://github.com/tobbelobb/hangprinter/tree/Openscad_version_3]Openscad_version_3 branch of Hangprinter repo[/url].

Mechaduino mounting, configuration and setup will be discussed here even though it is entirely possible to build a working Hangprinter v3 without Mechaduinos.
Mechaduinos are expensive, but they give closed loop control, a handy torque mode for pushing mover around by hand, and possibly auto calibration in the future.
Version 3 is designed such that Mechaduinos can be retrofitted.</description>

            <description><![CDATA[ Hi<br />
<br />
Well, yes, the dozuki site is empty since I haven't got the time to document stuff there. Doing proper documentation is a whole new project and unfortunately something you can't get done in only a moment. I've always had the plan to open source the frame and that will also happen, but currently I'm too busy with another project.<br />
<br />
So, maybe in winter when I get more spare time]]></description>

Hey!<br />
nice build!<br />
these are some great resources too!<br />
would you mind posting a link to this thread: <br />
<br />
[<a href="https://reprap.org/forum/read.php?423,868741" target="_blank" >reprap.org</a>]<br />

<br />
Hey!<br />
sorry been busy with life :P<br />
just looked at the link and it seems quite empty to me..?<br />
But would definitely be happy if someting with nice pictures and step by step was available ;)<br />
also would still love to build your transportable stand for hangprinter. would you have a moment to put out BOM and instructions?<br />
cheers<br />

            <description><![CDATA[ Hey!<br />
we may just start a new thread here that would at least have all the links with description of what can be found where. that should be easy.<br />
i could also add my hints other not so skilled builders may find youseful (wish i knew a month back :P)<br />
same could go for everybody else. it might turn out well... or not, but lets give it a shot?<br />
otherwise, shurely a centralised site withk nowledge base pictures and instructions, like you re describing it would definitely be an ultimate goal! we may get there one day i hope :)]]></description>

            <description><![CDATA[ Hi pvsfa!<br />
<br />
I honestly don't know how people manage to get the Hangprinters working given the state of the documentation. You must have searched for and found little pieces of information in very many different places. Like it says in the repo, this project does not yet have any stable branch. So no easy entry point for newcomers.<br />
<br />
Right now there has been a long pause in HP development for myself, both HP4 and HP3 development. Don't count on very much from me for a while still.<br />
<br />
If you know how to use git, you could always create pull requests to the documentation in the repo:<br />
[<a href="https://gitlab.com/tobben/hangprinter/tree/Openscad_version_3/doc" target="_blank"  rel="nofollow">gitlab.com</a>]<br />
The most good looking and flexible way to document would be to serve something nice on hangprinter.org/doc.<br />
Git does increase the threshold for participation though, so doing self-hosted and self-made webpage documentation requires a lot of effort and dedication.<br />
<br />
If you don't like to use time consuming tools like git and raw html, I still think it's best to keep the documentation close to the source, so I suggest trying the Gitlab wiki functionality:<br />
[<a href="https://gitlab.com/tobben/hangprinter/-/wikis/home" target="_blank"  rel="nofollow">gitlab.com</a>]]]></description>

            <description><![CDATA[ Hey all!<br />
recently I managed to get a hangprinter running (moving to be specific). I still have quite some work to do - code and finetuning - but i was wondering whether anyone, @tobben especially, would be interested in trying to get all the available hp3 documentation in one place? also perhaps adding a few tips for noobs like me wouldnt hurt. i am happy to set out for that and even though i might just go and do it, i dont see much point in that unless this would be coordinated with comunity and developer(s) as no one would ever even get to know such efforts exist. so now... is there a way someone besides you, tob, can eddit hangprinter.org documentation (in a sense of adding to it?) would it be a good idea to create a wiki page wher all the links and tips could rest at one place? but than, can this be linked from official channels so those interested would actually be able to find it?<br />
im possitive this could save some good deal of time, counting in days, even weeks :P<br />
or is the case that hpv4 is fully underway and no more development should be "wasted" on v3?<br />
looking forward hearing what you guys have to say. i really just wish for this project to grow, and i believe a decent semi-centralised documentation platforn may add to that :)]]></description>

            <description><![CDATA[ Hi,<br />
i am trying to build a HangPrinter too and i had a lot of hours spent searching and watching images, videos and build documentation for hardware, firmware, software. The hardest thing for me was to figure out how lines are installed properly. I did not built my hangprinter in real for now but planning to do it (sourcing hardware and so on). I drew some sketch for lines and wanted you to ask if understood it correctly. <br />
<br />
As far as i know there are 9 lines in total<br />
* A1 + A2  =&gt;  2 lines on one spool<br />
* B1 + B2  =&gt;  2 lines on one spool<br />
* C1 + C2  =&gt;  2 lines on one spool<br />
* D1, D2, D3  =&gt;  3 lines on one spool<br />
<br />
[attachment 113465 Zwischenablage01.jpg]<br />
<br />
to better follow i just marked the full A2 path for example. You can see that A2 joins A1 again at the effector (triangle).<br />
[attachment 113467 Zwischenablage02.jpg]<br />
<br />
I saw in Chris Basement videos that the A1+A2, B1+B2 and C1+C2 have a common knot on the effector slider each, while D1,D2,D3 have there own slider for each. So in total there are 6 sliders (by the way i thought using guitar tuner mechanics for this use case)<br />
<br />
[attachment 113466 apiceceeo__35762.1523303748.jpg]<br />
<br />
I'm happy to retrieve your feedback.<br />
cheers, Mario :-)]]></description>

            <description><![CDATA[ Yes, the firmware should be straight forward to install. Just use the Duet2CombinedFirmware.bin you find in the repo (https://gitlab.com/tobben/hangprinter/tree/version_4_dev/firmware/RepRapFirmware), and follow standard Duet installation procedure. Gcode should to the magic, yes :) Be aware that your ODrive configuration will affect the movements. Max acceleration, max speed, step size etc needs to be configured correctly in the ODrive firmware. There's an example that matches my specific motors here: [<a href="https://gitlab.com/tobben/hangprinter/tree/version_4_dev/firmware/ODrive" target="_blank"  rel="nofollow">gitlab.com</a>] Follow the official ODrive documentation to find numbers that match your motors.<br />
<br />
If the fishing line has any flex at all, this will affect the readings. So if the line (and hence the pattern) is stretched out, you might wind in 10.1 mm when you thought you did only 10.0.<br />
On the other hand, since you're detecting the pattern, you'll know when you have unwound the same segment of fishing line, regardless of how stretched it was when wound and unwound.<br />
This makes the system immune to a family of errors where flex is "stored" on the spool when wound in under heavy load.<br />
<br />
The line will always be twisted though. How would the system cope with that?<br />
And how would it behave if the line got very slack? Could we route the line through a very thin transparent tube, to keep it from kinking under the sensor?<br />
For such a sensor to be useful, it would need to be very fool proof since so many weird things can happen during a print.]]></description>

            <description><![CDATA[ Yeah, I was quite amazed too to be honest.<br />
<br />
The line snapped 5 mm before the knot I made to hold the weight. So the CF spool didn't have any effect on the snapping. I'm aware of the abrasive nature of CF, so it's not said that it could not happen, but in this case it didn't. I can print a new spool out of PLA, no problem. It will be interesting to test it.<br />
<br />
Let's see how I can setup a test rig. The motion repetition won't be a big issue once I get to setup the ODrive board and Duet. Is the firmware easy to install? Then, I assume a simple gcode does the magic?<br />
<br />
Btw, I wrote you yesterday a mail, but it's still in my to be sent folder (I forgot that the schools network is down for maintanance for couple of days) anyway, I wrote that I ordered braided PE fishing line that is two-colored (yellow/black), so it has a repetitive weave pattern, which could be used for line length readout with a IR sensor, as black plastic does not reflect IR light very well. That's why the material of black plastic can't be identified in automated recycling. Different plastics reflect IR light differently.<br />
<br />
So, additionally to the mechanics I was thinking about position feedback via sensor readout. Whats your opinion on that? There was also some discussion about measuring the line tension. Could that be useful to integrate in the motion system? At school we have a quite big range of sensors and other electronic equipment for prototyping. You can check technIcal details at <a href="https://www.seeedstudio.com/category/Grove-c-1003.html" target="_blank"  rel="nofollow">Seeedstudio Grove</a> <br />
You can hook these sensors very easy to arduino, rasbi, etc.]]></description>

            <description><![CDATA[ Woah, that's even more friction than I imagined. Impressive!<br />
<br />
CF enforced plastics have a quite rough surface.<br />
Where did the line snap?<br />
Was it the CF that wore down the line?<br />
<br />
Since I would be aiming for HP usage, I'd test numbers relevant to the application first.<br />
I'd use ca 50% more weight, speed and acceleration than my HP4 prototype is experiencing.<br />
So ca 5 kg of weight, accelerate 15 m/s² , up to 1 m/s. Use a distance of 1 m up and down, say 10k times.<br />
That's a 3h test. You could go crazy and just let it run all night if you're feeling confident ;)<br />
<br />
It would also be interesting to know if the mechanism works with pure PLA.<br />
A spool out of PLA printed hot (say 240 C) would give much less friction than the PLA-CF in your prototype, I guess.<br />
It would be interesting to know if it would still be enough, or if the CF is required.<br />
<br />
Images like the one you showed would be a very interesting part of the result.<br />
In particular, if the line does slip, I'm interested in how damaged the belt gets.<br />
Also interesting to know if a slipping line cuts into the spool.<br />
<br />
The mechanism is interesting in it's own right, so if the HP4 application proves to be well within limits of the mechanism, I would have done additional tests.<br />
Like, measuring a slowly applied force up until the line breaks or starts slipping, or until the plastic spool breaks.<br />
(Film a weight that is hooked onto a one end of a line, and pulled. Could capture both force and amount of slip/flex in one shot.)<br />
Abruptly applied force is also interesting (requires a high-speed camera, or a weight that can store a max value).]]></description>

            <description><![CDATA[ Thanks!<br />
<br />
I just put a heavy weight on the line and looked first if the line holds, and after I couldn't see any slipping, I bounced the whole system until the line snapped <a href="https://photos.google.com/share/AF1QipP941svHu60zA2lb4uy-EiuVIoL_OkNFKMXv9HkmQv1IpC6mATvBaFGsN7UJP3WJQ/photo/AF1QipOdquy9sI6ztk9QW4ccuoGtGpWLGjevc3XIrvNQ?key=MkJVWGdzUW9RWl9QNjZaaHVaQTVlc2VIOXpSeHhR" target="_blank"  rel="nofollow">Video: testing slipping</a><br />
No slipping what so ever :D <br />
<br />
I believe the line should be able to handle 40 kg of drag, so friction-wise I can't see any issues. Obviously the long term failure rate is a question mark, but I think it might work quite well because the line isn't cutting radially into the belt. The only force is applied axially and the belt is pressed by the line by only 0,25 mm<br />
<br />
Your idea of hooking some weight on the line and do some repetitive acceleration testing sounds very good! I'll try to set up the electronics next week. What values would you suggest for weight, speed and acceleration?<br />
Here are also some close ups of the GT2 spool and the belt directly after the test. For the spool I used Octofiber PETG-CF.<br />

            <description><![CDATA[ Cool!<br />
<br />
Independent spool units are nice.<br />
If you can place them at the anchors (instead of having all several spools at one anchor), you will get less line flex, since there will be less suspended line in the air.<br />
<br />
Good idea to pinch the line under the belt.<br />
That might actually work very well =D<br />
You could pinch it for several rounds (along a helix groove), or just increase the spool radius, if one round of pinched line isn't enough.<br />
<br />
It might be a challenge assure zero slippage over time, since both line and belt will change properties as they get old/worn down.<br />
Some data on that would be super interesting, like accelerating a 5kg weight quickly up and down 1 m 10000 times or something.<br />
Using high accelerations would be interesting because the belt will flex/contract a bit when tension changes, and I don't know how it will affect the line.<br />
Hopefully very little.<br />
<br />
Anyways, that might be a very nice upgrade of the spool system :)]]></description>

            <description><![CDATA[ I'm currently designing a bracket for the HP4 bldc servo motor and the spool, and I wanted to share my tests so far.<br />
The bracket is meant for the ODrive D5065 motor. My goal is to design a single motion unit, that includes the motor, a belt tensioner and the spool system in one rigid frame, which I probably am going to lasercut out of sheet metal. For now, I'm still thinking about the spool system. If you look few posts back in this thread, there was a discussion about the constant radius of the spool and how to compensate the line build up. An idea I had, was to route the line in a small groove in the middle of the GT2 spool, in the way that the belt is pressing it against the spool as you can see in the last pic.<br />
<br />
I just tried to block the spool from rotating and pulled the line as hard as I could and it didn't move at all :D<br />
It's still too early to say this concept works, but it is a promising start. It might be, that constant line movement is going to bite into the belt and it fails that way. You'll never know. What I'll do next is rerouting the end of the line onto a second spool, which I most likely will attach onto the same spool axle. And that spool will rotate independently from the first one. I was also thinking to spring load it, so that the excess line is always spooled up as the line moves.<br />

            <description><![CDATA[ Hello Tobben and others! A university on the East Coast U.S. is trying to build some hangprinters. Students at GMU's solar car team are trying to print a fairing for their car with one!<br />
<br />
I'm trying to lend them a hand, but the documentation on hangprinter.org seems to be focused on a closed-loop build. They're trying to avoid buying Mechaduinos or the like, and I can't seem to find information on it. Where should I be looking?]]></description>

Yes, this seems to be the case. Could this be an issue with flexing of the line spools since their axle is supported on one side?]]></description>

            <description><![CDATA[ The last project was sliced with cura 3.6 and the gcode wasn't as smooth as the code produced by simplify3d. The printhead jittered quite alot when printing the cura code. Also the print speed might have been a bit too high. But the biggest improvement so far has been the huge 1000 mm dia silicone heater mat, which I got installed a week ago. No more issues with first layer adhesion.]]></description>

            <description><![CDATA[ Interesting! Haven't seen this issue before, at least not this much.<br />
<br />
It would be interesting to know if the effector travelled in different directions on outer versus non-outer walls.<br />
Could it be that the plastic trace will look different when going clock-wise versus counter-clock-wise?<br />
<br />
Other than that, I would experiment with trying to make the nozzle mounting more rigid.]]></description>

            <description><![CDATA[ Hey<br />
<br />
Do you have had similar issues with print quality than I had with the last project (still going on)?<br />
The skin was partly separated from the printed object and that caused issues during post-processing (sanding, etc.) It affected only the outermost wall, the inner walls were connected as they should have been.<br />
Here's a picture of the crime scene. Any suggestions are warmly welcome, since I'm about to start the next project soon.<br />

            <description><![CDATA[ Hi pvsfa<br />
<br />
Those extruder clones might come as a cheap ootion, but from my experience the extruder/hotend combo is a critical component where you really should invest in quality hardware. For example e3d or Bondtech. I once ordered e3d Titan clones from China and they were so badly manufactured that they were practically not usable. Since then I'm sticking with e3d. It saves you the hassle, trust me.]]></description>

            <description><![CDATA[ Hello pvsfa!<br />
<br />
1) The HP3 should work with any electronics that with 5 stepper drivers or more.<br />
If you plan to use Mechaduinos/Smart Steppers, then you must also have access to i2c pins and step/dir pins. Not all electronics provide that.<br />
Very few have tried anything other than RAMPS, so you might bump into something, but most probably not much.<br />
I've used some RAMBO boards myself, and it was quite smooth. Just configure Marlin right, and it should work out of the box.<br />
<br />
2) I haven't tried clones, and I wouldn't recommend them. You will run into some slight differences, and unless you're an electronics engineer, you'll have to ask for help and wait for answers... These boards are quite tricky to make right. I recommend proper Smart Stepper bought from misfittech.net<br />
<br />
3) If you don't plan to print much with the HP, then a Volcano clone might be the perfect fit. I do recommend a proper SuperVolcano to anyone who plans to print more than just a few demo objects. The proper hot ends will typically perform much better. They will give you more nice looking prints with less hassle, and last much longer. It might be a super good clone, but it would be the first one that I ever saw. It is very very tricky to make these parts both good and cheap at the same time. If you have to prioritize because you really can't afford originals, then buy a genuine heat break, genuine heater cartridge, and genuine thermistor. You might need a genuine heater block to make everything fit as it should.<br />
<br />
I will not be able to support you easily if you have cloned parts, as they could have a very wide range of hard-to-debug faults.<br />
<br />
Best regards]]></description>

            <description><![CDATA[ back again with bag full of questions :)<br />
<br />
as i said, i aim to order most of my parts from aliexpress, mostly from makerbase and trianble labs. Still as Tob's BOM asks for either too a general item or explicitly different item, Id like to confirm a few things before actually placing the order. Here comes...<br />
<br />
1) Ramps + arduino mega 1.4/1.6 vs mks gen L<br />
I know BOM asks for RAMPS plus arduino mega. wouldnt Makerspace's mks gen L (<a href="https://www.aliexpress.com/store/product/3D-Printer-Control-Board-MKS-Gen-L-V1-0-Compatible-with-Ramps1-4-Mega2560-R3-Support/4746021_32970358377.html?spm=2114.12010612.8148356.14.10155b74vIhvSU" target="_blank"  rel="nofollow">aliexpress</a>) do just as well if not better though? I hear there's less hassle with it (plus i may use other hardware from them) but haven't heared of anyone from hangprinter community praising/using it.<br />
if it may not be such a good option after all than should i get ramps 1.4 or 1.6? <br />
<br />
2) mechanduino (clones)<br />
makerbase, as you surely know, manufactures mechanduino clones that come hooked to nema17 42 steps stepper already (<a href="https://www.aliexpress.com/item/3D-Printer-Parts-Open-Source-NEMA17-Closed-Loop-Stepper-Motor-MKS-SERVO42-Prevents-Losing-Steps-for/33007247421.html?spm=a2g0o.cart.0.0.1a763c00lvI9SC" target="_blank"  rel="nofollow">aliexpress</a>). now, as it is a clone, it should behave the same way (although they told me some pins are weired differently). anyways, does anyone has any experience with them? would you recommend using them or would you not? (id appreciate (expert) guesses too;)<br />
<br />
3) extruder+hotend<br />
im looking at this triangle lab e3d volcano ripp (<a href="https://www.aliexpress.com/item/3D-printer-extruder-titan-Extruder-for-desktop-FDM-3D-printer-reprap-MK8-J-head-bowden-free/32765576131.html" target="_blank"  rel="nofollow">aliexpress</a>) . i would like to get the whole "set 5" (need to scroll down to see the desription of various sets) which includes extreuder, hotend, motor, and fan. I read its a "good fake" as much of an oxymoron as it sounds. any voices against it?<br />
<br />
Id be super happy if someone could get back to me with any opinion or experience. i should be fine with other bits of the puzzle for now, but really can't make up my mind on mentioned topics.<br />
<br />
Best,<br />

            <description><![CDATA[ hey everyone!<br />
<br />
I ve been following the project for about a half year now. Sounds super exciting to me (ie my compliments to tob and all the other involved members, developers, testers and enthusiasts:)! Im not very skilled at 3d printing but I believe I will learn as I go as Im too messy to do proper preperations when it comes to just about anything. But than, hey -  I read all (yes, all 14 :P) pages of this thread, tob's blog, clicked on most of the links wherever i could, and started printing the parts, and am about to start oredring electronic components and hardware bits. I must admit, reading through all of this wasnt easy but helped me clarifed quite a bit. I feel I have an understanding of whats going on even though im missing a lot of details, whereas before i was just missing it all and only had this awesome 3d animation from hangprinter website going on and on in my head :D<br />
my motivation is to print full scale gallery exhibition on the spot using this machine, photogrametry, and heaps of luck. I also like the "style" with which printer seems to print as exposing the technology of 3d printing by leaving imperfect traces behind makes it actually more human and accessible to me.<br />
anyways, just wanted to share my enthusiasm here :) <br />
im doing a shopping list right now and the aliexpress mid year sale ends in 2 days so im hoping to get some insights before that, but that may be too optimistic of a wish :P<br />
still, i ll post here again in a bit<br />
<br />
cheers for now!<br />
