  1. Just want to say that this is definitely not due to retraction. I know what you're all thinking lol I downloaded this file from thingiverse for an Ender 3 Pro printer. I noticed poor surface quality and some blobs along the outside of the walls. I thought it was the printer, but I noticed the blobs in the gcode as well. When I animate the file, I can see that the nozzle slows down where the blob occurs and overextrudes in just that spot, then continues at normal pace. It usually occurs in the corners or rounded edges, but I have seen it occur on a smooth portion of a wall when there should be no need for extra extrusion. I noticed that the file is very high resolution, but I don't have the source file. So I used blender to decimate the stl until I reduced the file size to about 3.5MB. Can you guys look at the file and see if you can reproduce the blobs? You don't even have to print it, just reopen the gcode in Cura rather than use the Preview. Original File from thingiverse.STL file after blender decimate.stl latest gcode of decimated file.gcode
  2. Hallo miteinander und einen schönen Sonntag, Also wie im Titel beschrieben ist der PETG druck kein Problem, aber was mich nervt ist das die Nozzle Temperatur über die höhe des Bauteils nicht konstannt gehalten wird. Mit 235-220 Grad geben die Schichten ein Super Bild ab, ganz glatt und gut verbunden. Nun habe ich aber festgestellt das CURA die Temperatur über die Höhe des Bauteils von 235 Grad auf Bettebene bis auf 195 Grad bei 200 mm Höhe verändert. Das ist definitiv Mist. Wo kann man das in den Einstellungen von Cura verhindern das er unter eine bestimmte Temperatur geht? Wäre um einen Rat sehr dankbar. Beim Bild 235-195 sieht man oben rechts einen Bruch, weil das Zeug zu kalt gedruckt wird. MFG Willi
  3. Dear Cura plugin community, I would like to build an addon, with which I can display the printer's status and printbed temp within the "Monitor"-Tab. So far, I can query my printer via Wifi and get a json-style response via QNetworkRequest. However, since I am unfamiliar with Qt and QML, I am having troubles parsing this data to a Label within MonitorMain.qml So far, I have: MonitorStage.py: class MonitorStage(CuraStage): [...] def Response(self, reply): [...] response = json.loads#Here I get the json from the printer I'm having a hard time with Qt's signal/slot system, where I'm struggling to parse a value from the response to a QLabel in MonitorMain.qml Would any of the more seasoned programmers on this board be able to point me to the right directions? Best regards, hauschka
  4. Has anybody tried or had good results with the MatteForge Advanced Matte PLA filament? They claim it to produce nice and matt finish even in black. I'm intrigued.
  5. Hi, I had problems printing 2 parts at the same time so I made them print one and then the other. I left, because I had to go shopping for food, and when I came back, one model was nice done ( the first one), but the other was stuck to the print bed like crazy and when I removed it and measured it with calipers in the Z direction, the second model was about 3mm lower than the other and the ultrabase below it was all scratched up and the nozzle will probably need itself being replaced. From what I saw I can surely say that something (probably cura) made the second print start 3mm below the bed level, resulting in my bed being destroyed, luckily on almost the very edge. I had it leveled and when I checked the bed screws, none were loose. Leveling the bed afterwards wasn't necessary, the bed was completely leveled and the distance between the bed and the nozzle was the same everywhere, just the very tip of the nozzle got brushed off. If it is really the Cura's fault, it should be fixed ASAP. I was very lucky I didn't print it in the center and that it was a very small object, so I don't have to replace the whole print bed due to this. Anyone has any ideas what could this be caused by? Thanks.
  6. The problem occurs when I try to submit a file to Cura from within Fusion 360 I am using Mac OS Mojave version 10.14.6 Fusion 360 Version 2.0.6258 Cura Version 4.2.1 If Cura is already open, the file is transferred correctly but if it's closed, Cura opens and crashes and I get this message. If I choose a different application in the "3D print" pallet like for instance "Slic3er", I don't get that message and the app launches. So it seems to be specific to Cura in my case anyway. From what I could see in the few ours I spent trying to fix it, this looks like it's still an unresolved issue. If someone at Ultimaker want's to look at this bug, I will be happy to help in any way. I love Cura and I want to help if I can so that it's has bug free as possible. Thanks for your help. - Blaise
  7. Hi Just wondering is Ultimaker launching a new add-on for long prints where it loads a new spool automatically, say if you had a large print overnight or a weekend so there is less downtime. I see the Parusa now has a mutli material device that can load 5 different material/ spools. https://shop.prusa3d.com/en/upgrades/183-original-prusa-i3-mk25smk3s-multi-material-2s-upgrade-kit-mmu2s.html?search_query=multi+material&results=11 Can you do this with the second extruder, if the first runs out of material can the second extruder continue on.
  8. I'm printing a full plate of duplicate items on my printer, and I've noticed that the default for Cura is to print all the supports on a layer before printing the main body. This seems to be adding a lot of unnecessary travel time. Is there an option I haven't seen that could make cura print the support, then body, for each individual piece? So to be clear, currently it goes: Item 1 -> 50: Print supports, then Item 1 -> 50 Print Body I would like it to go Item 1 Print supports, print body, Item 2 Print supports, print body, etc..... Only thing close I've seen is print sequence, but that prints the entire object one at a time, and there's not room on my plate for that kind of motion. Thanks!
  9. I have been trying to figure this out for hours. Every time I combine these meshes in Maya, the cura print software tells me there is an error in xray mode I have no idea what the error is. Please Help. The two meshes separated. After I combined them, merged them, and Cleaned them up. What it looks like in cura. X Ray mode in cura telling me there is an error.
  10. here's the situation: Z Distance between the nozzle in Core 1 and Core 2 seemed not remembered by the firmware, or it is ignored during print, or something went wrong during calibration. Core 1 will always be well calibrated and printing well, however, Core 2 will always got pressed too close to the bed that blocks the filaments from coming out. After Active leveling, Core 2 nozzle always pressed too close the bed during print, as if it is ignoring the result done during calibration.. after running more of tests, it seems that Manual Leveling does not have this issue. I have done a lot of tests, switching print cores(i have purchased one extra print core), and the result is the same. So i guess it is not the problem of the print cores but something is wrong with the machine doing Z calibration. And it seemd to me the machine is ignoring the Z calibration that is done in active leveling, so every time when print started, it went all the way pressing nozzle too close to bed again. Not sure if this is a firmware issue but i would like to post here to see if it shines any clues. Some other users also have this similar problem and is forced to print on one nozzle (Core 1), unless one kept doing manual leveling and forces the machine to never do auto leveling thus not to override manual leveling setting. And this seemed to happen fairly recently, so i guess it could be something about the latest firmware update.
  11. Hello community, we recently got a brand new UM S5 in our company which now begins to show weird behavior... After firing up the first time it updated to 5.2.11 and printed its first 70 print jobs without problems. But now it constantly produces auto leveling errors, but beginning with the second print of the day. So, first print of the day works great every time, then auto level error every time. There are three different behaviors causing the error: - glass plate not touching printcore 2 (stopping like 10 mm underneath it), but touching the first PC: error - glass plate touching PC2, but stops 10 mm underneath PC1: error - glass plate not touching PC2 and PC1, but starting auto level anyways, just to cancel after 2 points: then error EDIT: The automatic print job restart, that the printer is doing by itself after an error is also failing every time. When I shut off and restart the printer completely, the first job prints flawlessly. But then the errors above start again... Even more weird is, that the sensor test in the maintenance menu says the sensor works totally fine. But when I start a print job right after that, the errors still happen. What I tried already: - changing out the printcores, no effect - changing the material, no effect - check for loose cables of the sensor (red and white one), they are tight, no effect - moving every piece of electronics like computer and cellphones away from the printer, no effect Do you have any more ideas? Is the sensor broken, even though the test says it's fine? Is it a software bug? Thank you in advance! Greetings, Cymon
  12. I have a few models that after being edited and are hollow on the back side, how would I go about making it print a solid back and bottom? Essentially trying to get it to look like Mr. Solo with a good base on the bottom with a solid back so you can not see the supporting material. Any Ideas?
  13. Hi everyone, this is my first post on this forum. I just updated from Cura 4.1.0 to 4.2.1 and i found that the generated supports don't work as they used to anymore. I've attached screenshots of both versions with the same model and the same print settings. In version 4.1 the supports were created as they're supposed to, but in 4.2.1 they stop sometimes halfway through, sometimes just before touching the object. The way this looks, I don't think the supports work quite right. Is this a known feature or bug or did I just mess something up? Thanks for your answers!
  14. Hi guys and gals 🙂 i noticed that Cura recently added information about the min and max coordinates of the sliced print like that: Are these also available via bracketed variables / parameters like {print_x_min} for use in the custom start/end Gcode? Would be great as they would allow for probing the bed in Auto Bed Leveling at the actual dimensions of the print (instead the whole bed) and defining a default gradient that stops at the actual top. Thanks and best regards Christian
  15. hi, The adaptive layers functionality almost perfectly solves a problem I had...but not quite. I am printing a (bald) head figure and so the top is basically like the top of a sphere. I am printing 0% infill and spiralized so if I don't use adaptive layers the only way the top part of the head will come out as a solid surface would be to print the entire thing at a tiny tiny layer height (there are holes/gaps between lines of filament near the top of the head). I tried printing without spiralizing with a one-nozzle-width wide wall and and a top thickness of a mm or so but that's ugly as the light coming through the model shows the internal structure which I absolutely don't want. Anyway: adaptive layers would actually fix this problem except when I printed it the top of the head melts. The layers are apparently very thin and the plastic keeps getting run over by the hot print head. Any suggestions on how to fix? If there were a post-processing g-code extension to make minimum layer time much greater the last few vertical mm's of the print that might work but I don't find such a thing. Is there? I haven't tried changing the extruder temp with ChangeAtZ v5.1.1 ....maybe that'd work but I kind of doubt it. Underextrusion? Something else? I saw this https://community.ultimaker.com/topic/10953-top-of-print-melting and haven't tried it yet. I'm playing around with the parameters in Adaptive Layer Height now but wanted to reach out and see if anyone had a similar problem and maybe a solution or suggestion.
  16. Bonjour, Sur mes prints j'ai un problème avec la coque extérieure, la couche externe souffre de défauts trop visibles. Je ne sais pas sur quels paramètres jouer pour améliorer le rendu. Je vous met en gros plan le problème sur le bateau du benchmark.
  17. I need help with making slots of 200 microns in a recangular block (10 X 5 or 10 X 10 mm2). i designed stuff with autodesk and started printing but the print that i got from machine has no slots on them. also i am using the material called ASA which is slightly differnet than ABS. I would be thankful any direction or help. Thank You, Siddharth
  18. Bonjour, J'ai un bug avec l'écran de mon UM2+, l’écran de l'imprimante se fige et je n'ai plus aucun contrôle avec la "molette". Malgré tout l'impression va à son terme mais une fois terminé le plateau ne descend plus et la buse ne revient pas à sa place initiale, elle reste en contacte avec la pièce imprimé. Pareil quand je souhaite changer de bobine de matière, l'imprimante ainsi que l’écran se fige pendant le processus. Savez de quoi il s'agit ? un bug programme sûrement ? Merci Cura version 4.0 UM2+ version 3.3.0
  19. Hello Everyone I Just got a UM3 extended, and i tried printing Gyro with Ultimaker ABS and PVA material, and i noticed that the bearings are broken so the Gyro does not spin, i looked on cura, where the bearings are supposed to be printed and it looked like a vierd way on how it was filling the axes, like the axes didnt connect to the rest material, so should i be printing it on less than 0.1 layer height, i used PVA support and just the default settings from cura, i changed the shell thickness to 6lines, but want to find more info on what other settings i should look at before i do another print, does anyone have any settings suggestions on what worked on their printer? Any useful information will be greatly appreciated Thanks Zig
  20. Hello ! I'm having trouble with my prints, as you can see on the pictures there are a lot of fails on the outer walls of my benchmark of the boat. I don't really know on which settings i should play in order to make it better. I've hear things like retractation and other stuff but i'm a little lost. I have circled in red the main problem on the print. Can somebody help me a bit ? I'm new to the 3d printing world but i've watched quite a bit of videos on youtube. All the parameters were set on defaut on Cura with a standard quality. Thank you
  21. Hi All, I have been having trouble with a print. I have done many prints and never seen this problem before. When I slice the model with Cura 4.2.1 some of the support material doesn't start printing until layer 7. This means that the support material doesn't form properly. I have tried to modify the model to remove the need for support material but this just moves the problem to another area of the print. I am confident that this is not an issue with the printer but with Cura. I am not having this issue with other prints. Can anyone suggest where I am going wrong. Thank you Michael Lycett
  22. Hallo! Ich habe seit ca einem halben Jahr einen Anycubic i3 Mega und bin fleißig am drucken. Mittlerweile habe ich die fünfte Rolle Filament durch und das Hotend ist nun auch das dritte... Alle bisherigen Probleme (es waren sehr, sehr wenige) konnte ich alleine lösen, aber nun weiß ich nicht weiter. Habe neulich für einen Han Solo Blaster ein Teil von thingiverse (https://www.thingiverse.com/thing:882673 - unten angehängt) gedruckt, am oberen Ende angekommen, hielt das Bett leider das Teil nicht mehr und alles verrutschte. Da wollte ich Schlaukopf das Teil einfach nochmal auf dem Kopf gestellt ausdrucken und dann einfach die beiden Teile zusammen kleben (was für ne Hirnleistung... XD). Nun passiert aber, dass beim Druck das Hotend nicht weiter als die erste Lage hinspuckt, dann auch fleißig weiterdruckt aber nicht auf der Z-Achse hochfährt dabei, sprich er schmiert sich einen großen Haufen Filament überall hin. Und das auch bei allen weiteren Teststücken, egal wie sie heißen oder welches Format. Das hatte ich ganz am Anfang schonmal, da half eine Neuinstallation von Cura. Nun nicht mehr... Mehrfach habe ich verschiedene Versionen komplett deinstalliert und neu installiert leider ohne Erfolg. Z-Achse lässt sich über Display und Cura heben und senken, alle Einstellungen waren so wie immer. Habe dieses Problem nirgends mittels SuFu finden können, vielleicht weiß ja wer Rat...? Ich bin nicht der absolute Hardcorecrack bei den Fachbegriffen, ich druck Dinge aus für Cosplay, Wargaming etc. So bitte ich eventuelle ungenaue Beschreibungen oder fehlende Fachbegriffe zu verzeihen... Uuuuund nochmal in übelstem Schulenglisch: bzw Aaaaand once again in worst school english: Hello! I've had an Anycubic i3 mega for about half a year and since i am busy printing. Meanwhile, I have emptied the fifth role Filament and the Hotend is now the third... All previous problems (there were very, very few) I could solve alone, but now I do not know farther. Recently printed a part of thingiverse (https://www.thingiverse.com/thing:882673 - attatched down there) for a Han Solo Blaster, arrived at the top, unfortunately the bed no longer held the part and everything slipped away. No problem, I intend to be a wise guy and just print the part again turned upside down and then just stick the two parts together (what brain power ... XD) . Now happens, however, that during printing, the Hotend does not spit more than the first layer, then continue to diligently print on but not moving on the Z-axis, so he smears a large pile of filament everywhere. And the same with all other test pieces, no matter whats their name or format. I had that at the very beginning, there helped a reinstall of Cura. Well, not anymore... Several times I have completely uninstalled and installed several versions without success. Z-axis can be raised and lowered on the display and Cura, all settings were as usual. Did not find this problem anywhere via search, maybe somebody knows what to do ...? I am not the absolute hardcore crack, just using the printer for parts for Cosplay, wargaming etc. I want to apologize, if the technical terms are not the best... flash_suppressor.stl
  23. Hi, I just updated to 4.2.1 and my profile settings got a bit off. I do have an old gcode file for a print from before I updated. I have tried to import the profile settings from it but keep getting the error code: The machine defined in profile doesn't match with your current machine, could not import it. I run an Ender 3, and did before the update. Any suggestions? Thanks in advance!!
  24. Hello Community, I have an ultimaker 3d mega since 3 months, printed a lot of technical parts and was quite happy with the printer. My problem seems to be a common one but I have tried all solutions I could find, and they didn't help: After about 10 minutes of printing, the filament is blocked within the hotend. For some minute fewer and fewer filament leaves the nozzle until nothing comes out. When I pull the filament out of the hotend, the distal 3 or 4 centimeters seem to be a little bit thicker than the normal filament. Twice I was not able to pull the filament out because it had become to thick and I had to cut the tube. The problem started sunday at a sudden with the same filament and setting I had used for a week successfully until nearly finishing the filament. I found out that this is a common problem connected with cooling or a bad fit between the teflon tube and the nozzle. I changed filament and used two types of PLA and one of PET-G. I changed temperature and number of layers various times. I switched retraction off and on again. I changed 3 hotends (the old one and two new ones, one that came with the printer and one i bought) I changed the nozzle various times. I changed the cooler because it seemed a little week but with the new ventilator the problem remained unchanged. I updated cura and tried to print directly from the printer via SD-card. I lost a lot of time and now I ran out of ideas. Does anyone have an idea what I could do/try? Yours Dirk
  25. I recently got myself a second hand (thirs hand maybe?) UM3, and after cleaning it up and doing all the calibrating, one thing still bothers me... The frame lights are completely different colours! The left is a very blue white, probably around 5500K and the right is a white so warm its basically a banana - Around 2300K if my well trained eye isn't mistaken. See attached picture, it's taken in overcast sunlight so pretty neutral. I can post more pictured once it's dark and the light is more visible. Is this a result of something up with the firmware or some random customisation, or are the strips just really weird? I know you can supposedly program these in full RGB, so if I can find a fix through that, I'd be more than happy to give it a go, too! Either way, this really hurts my soul at the moment.
