About Me



On The Web

  1. Hi guys, I'm fairly new to 3d printing. I printed a few premade models from the web with varying success, fiddled a little with printer settings, made my own smaller models/prints and decided to go for a more complex print. For that I made my own model in Blender, imported into Cura 5.1.0, applied my usual print settings, did a few tweaks and started the print. The first few layers looked good, although I was accepting a little warping on the far left end (x=75, y=220, z=0). I noticed that on earlier prints too, but I decided to keep going (big mistake?). However, on the next morning (after about 12hrs of printing) I encountered a print that has gone well for the most part, but then totally failed. I decided to stop the print at this point. Printer: Anycubic Mega X Filament: Basicfil PLA black Bed Temp: 60°C Printing Temp: 190°C (a little higher on the initial layers) This is my model in Cura: Thats the warping on the "far left corner": And those are the topmost layers of the print: Eventually, the left half of the print has detached from the print bed and shifted a little. At least that's what I decipher from this (and also the previous) area of the print: These are the questions going on in my head: Is it solely a problem of the print, or could/should I also do some improvements on the model? The lower parts of the walls (between the cutouts of the box) are rather thin and maybe too flimsy? Is it only a problem of bed adhesion? Could that alone lead to the weird printing issues? Maybe it's also a problem of a clogged nozzle or something? Is it a problem of air drafts during printing? The printer was operating in a rather small, closed and heated room without any people inside. So I guess the answer is rather "No"? I wouldn't like to just jump in and print it again with a few tweaks on my own, because the problems (besides the bed adhesion) only started to appear after ~8-10hrs printing time. I'm very grateful for any hints on improvements! I also attached my 3mf project file and can provide any further pictures or information that might be necessary. Thanks a ton, jam AI3MX_air_tower.3mf
  2. Moin Ich hab seit ein paar Jahren absolut problemlos das flexible material DSM Arnitel 2045 gedruckt. Anderes Flexibles Material hab ich nie wirklich zum Drucken bekommen. Als Grund hatte ich ausgemacht das das Filament mit einer Art Gleitschicht überzogen war und es so besser durch den Bowden tube flutschte. Rückstände dieser schicht konnte ich immer im Tub sehen wenn ich das Material gewechselt hatte. Jetzt musste ich feststellen das diese Gleitschicht bei zwei neuen Rollen wohl nicht mehr vorhanden ist. Das Filament fühlt sich jetzt stumpfer an und hinterlässt jetzt auch keine Rückstände im Tube. Jedenfalls kann ich es plötzlich nicht mehr drucken. da das Material im Feeder immer verkanntet. Jetzt hab ich mehrmals gelesen das einige bei Flexiblen Material etwas Öl auf das Filament oder in den Tube geben. Hat da jemand von euch Erfahrungen? wenn ja was nehmt ihr da? Einfach das Nähmaschinenöl was beim Ulimaker dabei war? Macht das Probleme? könnte mir vorstellen das das Öl dann auch auf das Glas kommt und die Haftung ruiniert
  3. I was printing this model when i encountered holes on my print (picture below). This also happened with vase-code models and single-wall prints. Anyone can identify the problem maybe?
  4. I adjusted the custom settings on the Cura software and can't tell if my Ender 3 S1 is adhering to them (primarily print speed). I want 20mm/s first layer, 60 mm/s infill, and 40 mm/s walls. When I slice it and move it over to my Ender, it just shows 100% speed the entire time. I'm not sure if that's 100% of the values I set in the program, or 100% relative to a factory setting on the machine. Any ideas?
  5. I’ve been having trouble with extreme stringing using Gizmodorks PVA. The strands wrap themselves around the shaft of the front fan, and even if I remove the strands from the fan after every print, they eventually kill the fan, which leads to the filament melting above the print head, which jams the material feeding system. I’ve had to replace the fan 3 times now. It may seem like a no brainer to just stop using the Gizmodorks PVA but it’s much less expensive and much easier to remove than every other alternative I’ve tried. I’ve also tried enabling retraction, increasing retraction distance, changing print temperature, and changing travel speed. None of these have helped. I’m currently printing the PVA at 35mm/s and 185 Degrees C. I think it’s important to note that the eSun PLA I use as the primary material has no issues with stringing. Does anyone have any experience with this material, or any suggestions for how I might resolve this issue? Thanks!
  6. Suddnely my both bondtech QR extruders doesn't work any more after an update, indeed the filament does not come out at all .. it just makes the skirt and then goes to extreme under-extrusion .. almost nothing .. before they were very perfect ..!! it is as if the steps x mm did not work .. there is under extrusion .. I checked via putty and everything seems to be ok ... firmware ultimaker 3
  7. Hallo Community, ich habe den Finder von Flashforge geschenkt bekommen und würde ihn gerne in Verbindung mit Cura testen. Ein passendes Profil habe ich bereits gefunden, doch leider scheitert schon die Verbindung. Im Netzwerk findet Cura keine(n) Drucker, auch nicht bei manueller Eingabe der IP. In der Software vom Hersteller muss ich den Port mit angeben. Versuche ich das in Cura, sagt der Assistent "ungültige IP". Beispiel-IP: Muss ich hier den Port anders eingeben, oder funktioniert das generell nicht drahtlos mit dem Drucker? Gruß Chris
  8. Hi. Just got Cura and have a question about the Barbarian plugin regarding converting from mm to inches. It only gives me the option to convert to to metric, but i was under the impression this plugin would allow you to do the opposite. My model loads into Cura and shows as mm but when i use Barbarian to convert to metric it gets too massive for the printer. am i missing something? Is there truly no way to convert "back" to my original model dimensions? Thanks!
  9. Hi, This is my first experience of 3D printing so I’m very green, but learning (as fast as possible). I’ve been given a CubeX single jet machine but I don’t have the toolkit or the Cubify USB stick. I've sorted various hardware issues and I think I am about ready to ask it to print. Hence, I have downloaded Cura 5.1.0 and in the Welcome Page, hit 'Get Started'. But when I try to 'Add a non-networked printer' there are no CubeX machines in the list. So, my question is -- Is there a way to add a Cura Profile for my ancient printer or do I have to enter all the details manually? (and which details are necessary?) Hoping you can help me. Regards, Myosotis.
  10. Recently needed to access some of the smarter Cura printing features for model planes on a Guider 2s. Found a few 'solutions' written over the past couple of years on how to link the two but could get none to work. I sense a mix of Guider 2s firmware evolving, some specific interpretations of codes by Flashforge, and an 'anomaly' in Cura. So took on board what I read (as much about what hasn't worked as what did), pulled apart some Flashprint and S3D G-Code files, and came up with something that works (as of August 2022). Short summary is the attached codes works for me on Cura 5.1 and Guider 2s (firmware g31 20211101). Note this Guider 2s firmware uses proprietary USB connection (can't connect to Cura through standard USB/com port), auto leveling (the attached code doesn't break the auto leveling sensor as others have experienced), and supports gcode files (so no need to change file extension) - just finish slicing, save to USB, and put USB in printer to build. Basic steps are: Set up new Custom Printer in Cura as per screenshots Add the start gcode and end gcode to the printer settings Add the Post Processing 'Search and Replace' rules to Cura (I have included these at the end of the gcode file, so strip them off and enter separately) I have also included in the screen shots my evolving gcode library for the Guider 2s that has the mix of codes that seem to be (mostly) active and seem to do what I have written. I am no expert so happy for any additional input that can help tidy all this up. A couple of the curve balls in this I picked up are below (and others may have better answers to these): M118 is used by Flashforge to dimension the outer edges of the build volume (including skirt etc.) based on centre of bed for X and Y axes, absolute for Z axis. So in Flashprint will be auto created to look something like this: M118 X32.69 Y15.50 Z49.10 (for centered Benchy). Those size variables don't seem to exist in Cura (MAXX, MAXY aren't quite them and don't seem available in code). So I started using the maximum values hard coded (M118 X140 Y125 Z300) but then found S3D just sets M118 X10 Y10 Z10 in all cases and it appears to work. Minor note: based on observation of this code executing, M104 and M140 seem to set temperature AND wait until temperature reached (or the code is not executed sequentially!!). Will test what happens if I remove M6 and M7 later to validate this. Under some circumstances Cura will set the temperature variable passed to M104 and M140 for extruder / bed (eg, M104 S{material_print_temperature_layer_0} T0) with 1 decimal place. That screws up the Guider 2s and it reads it as zero so sets minimum bed and Extruder temperatures. Hence the two Post processing scripts to tidy that up. Thanks to this thread for the workaround: https://github.com/Ultimaker/Cura/issues/8657 Case fan commands work, I just manually comment them out when not using. S3D and some Cura recommendations also suggest using M907 (eg. M907 X100 Y100 Z40 A100 B100) to set motor current. Flashprint doesn't. Not sure what best practice is here. Given the proprietary USB link / driver the best way I found to test gcodes relatively quickly (without slice, USB stick etc.) was through 3D Polar Cloud via network connection to printer. And as noted above - just save as gcode on USB and Guider 2s will go from there. This code emulates the S3D pre-extrusion along the front of the build plate before printing starts. Still refining this and will update as I get more prints done through Cura. Open to any other thoughts that help tidy up. Gibbo Cura-Guider_2s.gcode
  11. I have a Flashforge Creator Pro 2, and printing with Cura is mostly going well, but I'm having one small problem that's making prints tend to go wrong right at the start: my second print head doesn't visit the prime tower on its first layer. I'm printing with PLA and PVA; I put down a raft of PLA so the PVA supports have something easier to adhere to, which is great in theory, but it means there's several layers of nothing but PLA printing the raft while the PVA just waits for the first time it'll be used; even with a lowered standby temperature, it takes a moment for the PVA flow to turn out well after that. In theory that's what the prime tower would address, but I just finally noticed: the first time the PVA head comes out, it goes directly into printing the supports, ignoring the prime tower completely. On all subsequent layers, it comes out, adds to the prime tower, and then adds to the supports; but the first layer is when it really needs the prime tower, since it's been waiting so long, and it skips it completely, and as a result my first layer of PVA tends to have like an 80% chance of just being spaghetti. (If it survives that first layer, all the subsequent ones are fine, so the prime tower clearly does its job, when the printer isn't skipping it!) Is this a bug resulting from combining a prime tower with a raft, maybe? Has anyone else run into it?

  13. Hello to group. I have experienced these artifacts over time and have no explanation. Using Cura 4 Do any experienced user have an idea for these patterns? Many Thanks Richard B
  14. Not sure if I just wasn't looking good enough for an Ultimaker S3 profile, but it looks like there is none for PrusaSlicer and/or SuperSlicer. Am I right?
  15. Hello, im having trouble with vase mode seam ant some artefacts marked on foto. Im using ender 3v2 Material PETG 230C nozzle 80C bed Any suggestions?
  16. I've been experiencing a very strange stuttering-stepping/simultaneous under-extrusion in some areas of prints specifically when sliced with Cura 5.1.1. These same prints seem to print just fine when sliced with Slic3r PE. I have an Ender 3 Pro with the 4.2.2 (512kb) board running Marlin 2.1.1 with an added CRTouch, but otherwise stock. I'm a bit puzzled as I can't find any videos of others exhibiting the same issues. I've linked to some videos which showcase the problem behavior: Any idea what could be going on here? I am using the default Standard Quality profile in Cura as well as the default Ender 3 Pro settings, and I'm printing via MicroSD. I've tried 3 different MicroSD cards with the same results. I use 200 hotend temp and 60 bed temp.
  17. Hello UM_Community, I am trying to experiment with my 3d printer to make 2d drawings by adding a pen to the print head. I generated a simple Hello World Code from Inkscape with the J Tech Plugin used for Laser cutting, which is not able to be printed on my UM3. It says Print time 0:00 and doesn't start. Probably there needs to be a definition in the beginning of the code defining certain values. I attached the Hello World File. Does someone know how to edit the code and definition so that the printer is able to read the printjob? Also, to give a bit more context to what the idea should be, I add this video: Best regards! Hello World.gcode
  18. Does anyone anyone have setting for the Neptune 3 yet? Thanks!
  19. I currently have an SKR2 in my Ender 5+. I have 2 part cooling fans wired to the Fan0 and Fan1 ports on my board. I have been trying to configure Cura to control both fans during the coarse of a print, but I haven't been able to figure out how to configure this. Can someone please point me in the correct direction?
  20. hi i have for a lot of complexe can i want to block travel moves in some area same as support blocker, maybe some people like the idea and we can look in to this.
  21. Found this article "Ender 3 Neo is not in list of printers in Cura 5.1.1 for macOS" and wondering if I can follow it to get my Ender up and running?
  22. (German Text below) Hello everyone, for a few days I have been dealing with the challenge of wanting to print very large components, for which the 0.8mm nozzle would be ideal in terms of time, but at the same time I must not lose the level of detail in some places that the 0.4mm nozzle can do is reached. The components are prototypes, which are later manufactured as injection molded parts. The containers are tested in many variants and have sizes from 400x600x120mm to 400x900x250mm. Sample photo attached. The printer (CreatBot F1000) has two separate extruders. With PLA we have achieved very good results with the 0.8mm nozzle and a layer thickness of 0.5mm, as well as with the 0.4mm nozzle and 0.25mm layer thickness. For very large components, with only a few areas with increased accuracy requirements, I would therefore like to print with the 0.8mm nozzle in general and the details with a 0.4mm nozzle. The details are available as a separate design in CAD and can therefore be imported into Cura via a separate STL. In Cura V5 I managed without any problems to position the two parts exactly to each other and to assign the extruders with the respective settings accordingly. The only thing I can't get a grip on is the layer height, which is always automatically adopted for both extruders together. In my opinion what is needed is a feature that is able to print two layers in the areas where the 0.4mm nozzle and the 0.25mm layer is selected and then with the 0.8mm nozzle and a 0.5mm layer runs over the remaining areas... What has been successfully tried so far: -Printing with two 0.8mm nozzles and different PLA colors -Printing with two 0.8mm nozzles and PLA and PVA -Printing with 0.8mm and 0.4mm nozzle at same layer height 0.25mm -Print only with 0.4mm nozzle and PLA What is NOT possible: - Separation of the components as example in the second attached image, as some variants have relevant functional contours directly on the inside of the container. If changes are made there, either the coated steel parts no longer fit in, or the tests with the robots are no longer meaningful enough. -Assign the two extruders for different line types, e.g. extruder 1 for walls and extruder 2 for support structure and filling, because the walls take the most time, but are also the relevant lines for the details. Printing times: -The container from the attached picture (400x600x120mm) needs 1.5 days with the 0.8mm nozzle and 0.5mm layer thickness -The container from the attached picture (400x600x120mm) needs 5 days with the 0.4mm nozzle and 0.25mm layer thickness -With a layer thickness of 0.25mm and sometimes the 0.8mm nozzle, e.g. for the first floor layers, you save 9 hours of printing time, but it still takes far too long for the entire part. Original STL file cannot be attached for copyright reasons. Unfortunately, Google and the forum search have not gotten me any further. That's why I hope for the concentrated competence in this forum! Many greetings Sebastian ##################################################### Hallo in die Runde, seit ein paar Tagen beschäftige ich mich mit der Herausforderung, dass ich sehr große Bauteile drucken möchte, wofür vom zeitlichen Faktor die Düse mit 0,8mm ideal wäre, dabei aber gleichzeitig an einigen Stellen nicht die Detailgenauigkeit verlieren darf, welche mit der 0.4mm Düse erreicht wird. Bei den Bauteilen handelt es sich um Prototypen, welche später als Spritzgussteil hergestellt werden. Die Behälter werden in vielen Varianten getestet und haben Größen von 400x600x120mm bis 400x900x250mm. Beispielfoto im Anhang. Der Drucker (CreatBot F1000) hat zwei separate Extruder. Bei PLA haben wir mit der 0,8mm Düse und einer Schichtstärke von 0,5mm sehr gute Resultate erzielt, ebenso wie mit der 0,4mm Düse und 0,25mm Schichtstärke. Bei sehr großen Bauteilen, mit nur einigen Bereichen mit erhöhter Anforderung an die Genauigkeit, würden ich deshalb gerne generell mit der 0,8mm Düse drucken und die Details mit 0,4mm Düse. Die Details liegen als separate Konstruktion im CAD vor und können somit über eine eigene STL in Cura importiert werden. Ich habe es in Cura V5 ohne Probleme hinbekommen, die beiden Teile exakt passend zueinander zu positionieren und die Extruder mit den jeweiligen Settings entsprechend zuzuweisen. Einzig die Schichthöhe, welche immer automatisch für beide Extruder übernommen wird, bekomme ich nicht in den Griff. Meiner Meinung nach wird ein Feature benötigt, das in der Lage ist, zwei Schichten in den Bereichen zu drucken, für welche die 0.4mm Düse und die 0,25-mm-Schicht ausgewählt ist und dann mit der 0,8-mm-Düse und einer 0,5-mm-Schicht über die verbleibenden Bereiche läuft ... Was bisher erfolgreich versucht wurde: -Drucken mit zwei 0,8mm Düsen und unterschiedlichen PLA Farben -Drucken mit zwei 0,8mm Düsen und PLA und PVA -Drucken mit 0,8mm und 0,4mm Düse bei gleicher Schichthöhe 0,25mm -Drucken nur mit 0,4mm Düse und PLA Was NICHT möglich ist: -Auftrennen der Bauteile wie im zweiten angehängten Bild, da bei einigen Varianten relevante Funktionskonturen direkt an den Innenseiten der Behälter sind. Wenn dort Veränderungen vorgenommen werden, passen entwerder die beschichteten Stahlteile nicht mehr rein, oder die Versuche mit den Robotern sind nicht mehr aussagekräftig genug. -Zuweisen der beiden Extruder für unterschiedliche Linienarten z.B. Extruder 1 für Wände und Extruder 2 für Stützstruktur und Füllung, weil die Wände die meiste Zeit brauchen, aber halt auch für die Details die relevanten Linien sind. Druckzeiten: -Der Behälter aus dem angehängten Bild (400x600x120mm) benötigt mit der 0,8mm Düse und 0,5mm Schichtstärke 1,5 Tage -Der Behälter aus dem angehängten Bild (400x600x120mm) benötigt mit der 0,4mm Düse und 0,25mm Schichtstärke 5 Tage -Bei 0,25mm Schichtstärke und teilweise der 0,8mm Düse z.B. für die ersten Bodenschichten, spart man zwar 9h Druckzeit ein, braucht aber für das gesamte Teil trotzem viel zu lange. Original STL Datei kann aus Copieright gründen nicht angehängt werden. Google und die Forensuche haben mich bisher leider nicht weitergebracht. Deshalb hoffe ich auf die geballte Kompetenz in diesem Forum! Viele Grüße Sebastian
  23. With the release of the Cura 5.0 beta, a lot has changed in the core of Cura. So much so, that in order to be compatible with Cura 5.0, all plugin need to be updated and resubmitted to the Marketplace. I maintain a number of plugins, and you can imagine that it takes a while for me to update the plugins but also for the Ultimaker dev team to review them. I will use this post to share with you a growing set of pre-release versions of my plugins so you can test them with Cura 5.0 beta. Edit: All plugins are now in the Marketplace, and the prereleases for these plugins below should no longer be used (but will remain available on github) OctoPrint Connection: https://github.com/fieldOfView/Cura-OctoPrintPlugin/releases/tag/v3.7.0-DEV Mesh Tools: https://github.com/fieldOfView/Cura-MeshTools/releases/tag/v3.7.0-DEV Sidebar GUI: https://github.com/fieldOfView/Cura-SidebarGUIPlugin/releases/tag/v4.3.0-DEV Measure Tool: https://github.com/fieldOfView/Cura-MeasureTool/releases/tag/v1.1.0-DEV Z Offset: https://github.com/fieldOfView/Cura-ZOffsetPlugin/releases/tag/v3.7.0-DEV Linear Advance: https://github.com/fieldOfView/Cura-LinearAdvanceSettingPlugin/releases/tag/v3.6.0-DEV Edit 4/23: OctoPrint Connection: https://github.com/fieldOfView/Cura-OctoPrintPlugin/releases/tag/v3.7.0-DEV (updated) Arc Welder: https://github.com/fieldOfView/Cura-ArcWelderPlugin/releases/tag/v3.6.0-DEV Start Optimiser: https://github.com/fieldOfView/Cura-StartOptimiser/releases/tag/v3.6.0-DEV Titlebar Info: https://github.com/fieldOfView/Cura-VersionInTitlebarPlugin/releases/tag/v3.6.0-DEV Automatic Slicing Toggle: https://github.com/fieldOfView/Cura-PauseBackendPlugin/releases/tag/v3.6.0-DEV Edit 4/25: Printjob Naming: https://github.com/fieldOfView/Cura-CustomJobPrefix/releases/tag/v3.7.0-DEV Material Cost Tools: https://github.com/fieldOfView/Cura-MaterialCostTools/releases/tag/v3.6.0-DEV Setting Visibility Set Creator: https://github.com/fieldOfView/Cura-SettingVisibilityProfileCreator/releases/tag/v3.6.0-DEV Printer Settings: https://github.com/fieldOfView/Cura-PrinterSettingsPlugin/releases/tag/v3.6.0-DEV Edit 5/6: Material Settings: https://github.com/fieldOfView/Cura-MaterialSettingsPlugin/releases/tag/v3.6.0-DEV I will update this list with prereleases of other plugins, or when a new prerelease is necessary to fix a bug. To download these prerelease versions, go to the linked page and scroll down to the 'Assets' section. There you will see curapackages compatible with different versions of Cura. For Cura 5.0 you will need to download the file ending with `Cura5.0.curapackage`. After downloading that file, drop it onto the 3d viewport in Cura 5.0 as if you were opening a 3d model. You will then be prompted to restart Cura. You can drop multiple curapackages one after the other without restarting each time if you want to install multiple plugins. If you want to test these updated release in an older version of Cura, please download the curapackage labeled for that version. It is quite early days, and some of the plugins required extensive work to make them compatible with Cura 5.0. Feedback is welcome, either here or in the issue queue for the respective plugins.
  24. Hey guys, I need help setting klipper for my UM2+. I have installed klipper with ultimaker preset profile and had to adjust travel limits and Z steps, but looking good so far. The problem I found is hotend fan is not working (even if i heat extruder to 60C+). I don't know how to use gpio pins in klipper. For example I have this settings for part cooling fan and its working perfectly: [fan] pin: PH4 But that PH4 pin is PWM pin J14. How can I find relations for those pins (PH4 = J14)? My hotend fan is connected to J34, but I don't know how to make it running. Anyone have working printer.cfg for Ultimaker 2+?
