  1. This project is very much alive! We've not been spending 100% of our time on it (since we also had to work on the CAD file importing, which took a fair chunk of our time). We are currently picking up some work for Arachne again. As it stands, we will have at least one aditional pre-release of Arachne before the full release. I expect that there might be a few more prereleases, as the changes are pretty big, so we really need to get things right!

  2. As others have written already, it is incredibly convenient when combined with a material station (and multiple printers) for the S5. Personally, for spools which I "load and use to completion" (such as DPA or PVA support material) I usually don't bother adding an NFC tag to them -- there's not much being time saved. However for spools that I need to load/unload several times (such as rarely used colours or materials) having them be autodetected by way of an NFC tag is an incredible convenience. It also takes the uncertainty out of asking somebody not used to the printe

  3. It's a know problem of the slicing engine. You can play with a different line width but often you cannot get rid of it. But download and try the new Arachne engine alpha/beta Cura. I use it since the first alpha version and I don't see this issue anymore.

  4. Hi @UALib3D, I've just printed your model using Cura 4.10.0 and Arachne engine beta. Printed it with black TPLA as it (black color) have better emission than any other color. As I've an UMS3, I used same print quality profile (corrected with your setting and those I've added). Made some pictures of the two prints in daylight for better details.. The first two pictures is just finished printing with Cura 4.10.0 : In this two pictures above you can see the boundary between the support and the model. The support just snap

  5. J'aimerais connaître le nombre de personnes qui n'ont posté qu'une seule fois et que l'on ne voit plus? Et sur ce nombre, combien ont lâché complètement l'impression3d car ils pensaient que c'était facile et qu'il suffisait d'appuyer sur un bouton. (Car ils ignoraient tout l'amont de la chose notamment la conception de la pièce en 3d)

  7. No it is not. The bug that this thread is discussing caused the renamed printer to revert back after a restart. You have hit a particular case of "known behavior". In your case, you are trying to rename the printer to a name that is already taken up internally, so Cura adds the number (" #2"). You can rename the printer to anything other than the name without the "#2" postfix, and the rename should work.

  8. @Dan92 en modélisation oui il faut de la rigueur. Bien que ce soit fait par ordinateur, si il y a une erreur c'est parfois/souvent de la faute de la personne qui est devant son écran. Mais ça s'apprend au fur et à mesure malheureusement il n'y a pas encore de bouton magique pour sortir ce que l'on veut 🙂 C'est d'ailleurs pour cela que lorsque l'on me demande de modéliser un personnage, je ne peux pas le sortir pour 20€ au grand désarroi de certains ^^ Donc non seulement il faut de la rigueur mais aussi du temps, des tests, qui forgent l'expérience. @Nano-nc et @darkdvd, niveau cylindre, j'a

  10. #metoo Ultimaker disappointed me too with there Apple style approach of GUI's. We are engineers! We have to deal with technical systems. As ZD3D calls it, not with toys. An simple temperature indication would have safe me an hour on finding out the wrong profile was selected for some part. Feed-rate an speed are also not that hard to plot on the GUI. And maybe it's the lake of processing power for the display but the "fade" effect between selection and menus is on addition of the poor rotary button extremely toy feeling. Please give us tools to work with. Not a toy with one play button!

  11. Hi all, We've released 6.5.0 for the S-line printers to the latest firmware channel. There's some real nice updates in there, check out the release notes page. Just to highlight a few: Scan USB drive for material profiles. It will now be possible to add a material profile to the S-line printer from a USB drive. The printer can update its material list with any missing material profiles found in the print job files (UFP files) of an inserted USB stick. Import the profile by navigating to maintenance -> import material profiles. This allows for offline

  12. It is easy to find the Cura.log file. Open Cura, got to the HELP menu, there you find a topic with Show configuration folder, click on it. Then am explorer window opens with the folder and there you find the Cura.log file. You should also understand that a log file is needed to get more informations about the problem. Just to say it is not working is not enough to find and reproduce an failure, so it is fully understandable that they need this information. Anyway, now you know where to find the Cura.log file and you should be able to open an issue again on Github

  13. OK, so this is the print of Pyramid 5. There is very little difference between the two methods of spiralize. One with smoothing on (left side) and one with smoothing off (right Side). Not really much difference. Could have tweaked the settings to get the top to print better, but it was not the issue. Also lousy trimming of the brim. However, after re-reading the OP, I noticed it did mention using Pyramid 4 and I found the issue immediately: Here you can see that a straight slice produces the holes, or gaps. I used Cura 4.8, but have no expectation that there would be any

  14. This is not a model error. This is the setting "Enable coasting". You can find this setting way down in the Experimental tab in cura. It is probably enabled in your given printer profile. This is just disabled in a generic new one. You can use your given profile and just disable this setting. What this does is it stops extruding material just a bit before it reaches the end of the line. This last bit is displayed as a travel move in the layer preview. The purpose is to use the molten filament in the nozzle for the last bit of a line instead of extruding unt

  15. Actually, I made it all up. I have no idea if any of that is true or not.🤪 Cura shows the extrusion moves and with coasting enabled there is no extrusion there. The nozzle travels there so that little part is a continuation (vector wise) but there is no E in the line of gcode so the pressure just bleeds off across that distance.

  16. Unfortunately, there is no way to do that with a cutting mesh. The cutting mesh cuts the model into multiple parts, and they will all have their own walls.

  17. Hi @Smithy and @Josh_gpi, For the lab, I bought several extra glass beds. For more finicky prints we use the Ultimaker adhesion sheets. Spares are great to have. Yes, we attached the magnetic sheet on glass and that works great with active leveling. You can also, if you feel it is too close, use the z offset plugin and add some Z + if you feel the active leveling is too close. I know we've done all sorts of stuff on them but I can't recall if we have done PC on it. On their website they offer some guidance... PEX Build Surface

  20. I passed on this one because there isn't any real information. A project file would be good. Knowing the Operating System and maybe even the video sub-system would be nice. Knowing your printer would be a help as well. Why did you bring up Firewall? Were there previous issues with your installation? Is Octoprint involved? Just providing the Cura.log file might give evidence of the "What" but probably not the "Why" and having to muddle through a 1mb text file is not one of my favorite things.

  21. Calm down. People just didn't spot your message. Note that this is the forum of Ultimaker, so most people have experience with Ultimakers, so any help you will get here will be mostly focussed on that. Your first point of contact should always be whomever made your machine; They know most about it and should provide you with support if you need it. That being said; I don't have your model, so i can't see what the problem is.

  22. The cause of this is probably that the walls are too thin. You could use print thin walls. Or use Arachne, there I could slice it perfectly, because of the variable line widths. See here: Here you can read more about our Arachne Engine: https://github.com/Ultimaker/Cura/releases/tag/Arachne_engine_beta

  24. Also wie erwähnt, es druckt sich wunderbar ohne viel herumtricksen, hier der Cheat Sheet für Cura und Drucker: https://addnorth.com/knowledge/articles/petg-cura-cheat-sheet Nur den Infill auf max 40mm/s setzen, bei 50mm/s hatte ich ein paar Probleme, aber ich denke das kommt auf die Größe des Objekts an. Z-Hop brauchst eigentlich gar nicht aktivieren und Brim brauchte ich bisher auch nicht. Desweiteren benutze ich noch die Glasplatte mit 3DLAC, nach der Abkühlung gehts easy runter.

Hi all, Havent posted in a while due to taking a bit of time out during covid, but now am back and more motivated than ever hopefully, Just finished this off for a friend, and the compartment was a last minute addition, just drilled out and slotted in, I havent made many functioning parts but it works well and the tolerance is so tight inside that the pot slides out like the lid of a new iphone box, smooooothly. So satisfying. Ill post a quick vid soon, but have already given the it to the new owner and not taken enough photos lol. Not sure how much ashes actually go in an urn so maybe if

  32. Yes it is still alive and yes you can install it in parallel. Not 100% sure about the profiles, but normally when you install a different version, all your settings will be copied to the new configuration folder.

  33. For me personally first and foremost, I like to work on tech projects among my many other types of projects, so its fun for me. Learning about the intimate details of NFC tags/data also allows me to be able to use that knowledge in other projects as well in the future. That thought process really does open a Lot of doors in terms of what you're able to do on your own without a having to be at the mercy of a company to design/make something for you. What initially caught my interest was the filament usage data and how Cura will let me know what rolls I currently have loaded on the machine. I ha

  34. Hi all, following this video I was playing with Z hop to print an inlay on the bottom of my print (the TL;DR is print the small inlay first, then print the rest with Z hop enabled to a value higher than the inlay height). It works well, but there's a caveat: on a printer with an imprecise Z axis (like my Ender 3), having Z hop enabled can lead to a messy print, as the imprecisions on the Z will sum up quickly with every hop. Leaving aside the obvious fact that the Z precision should be high enough to be able to use Z hop for the whole print, the next best way would be to disable th

  35. selon la forme de ton objet, la déformation ne sera pas identique donc la modification non plus. sur un cube test environ 0,1 mm c'est très vendeur comme test, mais sur des surfaces courbes orientées différemment tu peux avoir 0,3 mm. c'est pourquoi il est conseillé, quand on veux une grande précision, de faire un proto d'abord. puis de corriger le 3D.

  36. merci mais tu ne montres pas tous les paramètres, mets l'affichage des paramètres en "all" ce sont tes réglages du "support" qui m'intéresse le plus. si aucun paramètre n'explique ton problème, je ne vois que ta bobine de PVA comme cause racine. et si tu ne veux pas faire d'essai avec un autre filament soluble, il ne te reste plus qu'a faire tes supports en tough PLA.

  37. I know there are some oddities with Hole Horizontal Expansion but I hadn't run into this before. I drew a test box 50mm square with 5mm walls and two 8mm cross holes. I exaggerated Hole Horizontal Expansion to 3.0mm. This is a slice through the center of a cross hole. In this area the walls are still 5mm thick. Here is the model at the last layer below a cross hole. The wall is 2mm thick as the 3mm HHE is applied to the square vertical hole. (This happens to be layer 380.) Here is the very next layer (381) and Cura has reached

  38. Hi RogerBW, this seems a very common issue which is simple to fix. There's a good tutorial by @fbrc8-erin: The video refers to an UM3, but as the sliding blocks are the same for the UM2, you can refer to it 1:1. Regards

  39. Yes when it is really so cold then this is the better choice. I guess just covering the printer could work, but then you get maybe other problems when the difference between "outside" and "inside" the printer too high.

  40. Bonjour Dan, Tout d'abord merci pour le stl Donc en l'ouvrant, cela me confirme que tu t'y es mal pris pour la modélisation. Encore une fois, je ne connais pas Fusion 360 mais voici ce qui ressort de ton stl : 1 - Bien qu'il puisse s'imprimer "correctement" malgré les petits défauts, ton objet n'est pas "fermé"/"soudé". En gros chaque face est indépendante les unes des autres. 2 - Faire 2 cylindres extrudés superposés n'est pas la meilleure façon de modéliser. Il y a au moins 3 "bonnes" façons de procédés pour avoir un résultat correct. - Création du cylindre de 74mm extr

  42. @jrbarron and @lenigma1 Having very recently received a 3D45 I've run into the same issues as both of you regarding the gcode that the TeachingTech's website produces. I've found that the line reading "T0" causes the printer to go through the bed leveling calibration, heat up, then immediately quit once the printer is up to temp. removing that one line allows the print to proceed, but as @eduncan911 points out - there are a huge number of other settings that are unique to each printer (and material).

  46. Is your nozzle small enough to print those thin features in the model? It's most likely that the walls of the actual lemon shape are too thin to be printed with your current settings. When I slice it using a 0.4mm nozzle most of the shape is removed because it's too small. A quick ugly "fix" is to increase the setting "Horizontal expansion" to make the features slightly fatter, but it's better to adjust in CAD. I also got a warning that the model is not water tight so it might need to be repaired as well.

This was a section were there was a banner with a banner that change every week (in my memories) (check image) Maybe this is what we have now in "Create -> File Download". But to see what others made we have to switch in different thread. I think that Pin Sections will help a lot. Like the "Usefull Links" made by @DidierKlein, add a "Welcome charter to read"...

  48. Me too! But I think some key features are missing here to make it a 'professional cloud printer'. - remote light control - queue up for prints - proper progress view in cura - possibility to add a webcam (something we instantly realized we will miss) to name a few. But I am looking forward to see those and others beeing integrated in future firmwares 😉 But that's critism on a very high level. Our previous printer was a constant pain in the a**
