  1. Running Cura 4.3 on Win 10 64 bit OS I need to edit the start gcode to change ESTEPS on my Ender 3. I am changing to a BMG extruder and the start gcode box is too small to even see a whole line and I am not a fan of reloading firmware to make the changes. I saw some other posts on this but no fixes. I tried messing with resolutions for the display and nothing helps. I tried it on my work laptop running the same OS and it does the same thing. I suppose I could switch to a different slicer, but Cura has worked well for me so far and I really don't want to take on a new piece of software. If someone has an actual fix or workaround I would appreciate the help. Thanks for listening.
  2. Hello, after a few hours of printing the targeted temperature E0 drops from 200°C to 0 AND the bed temperature drops to 0 too (with an error message). After 30 hours of printing my print failed and I couldn't resume the printing again. My fans are working fine. What could be the cause? UPDATE: New power supply arrived. I installed it (+ new silent fan, the original is very very loud) and i started a new print. 30 min printing and looks fine. Will update again the next day! UPDATE 2: I think the new power supply did the trick. After a 33 hours print everything was printed fine without interruptions of any kind (like hotend or heat bed temp drop). I guess there was either some high peak voltages sometimes that killed my original power supply. Now I'm using a multi socket with an inbuild overvoltage protection.
  3. Guten Morgen, kennt jemand den Fehler "communication error with the print head"? Kommt bei uns immer mal wieder. Drucker stoppt dann mitten im Druck. Nach Neustart alles wieder i.O. Ich vermute Kabelbruch, außer ihr kennt eine andere Schwachstelle? Gruß Andy
  4. Hi, sometimes, large and flat parts are very hard to remove from the bed. So I used large pockets with a depth of 0,15mm to reduce the adhesion area. But with that distance, the extruded plastic curls. You cannot lower the depth of the pocket, because Cura ignores everything smaller than 0,15mm - you will see it in Cura preview. Green is bed contact area, blue is pocket (and a print into air). So how to make Cura accept flat pockets? Files with 0,05 and 0,15mm are attached. Adapter HY20_00.stl Adapter HY20_05.stl
  5. Again and again I have gaps in different objects in the top layer, but only when printing on my UM2Go The result looks like this: In Cura layer view, everything looks fine: So I investigated several hours to solve the issue. What I have tried and done: Different object heights -> doesn't matter it is always the same Reduced speeds -> still the same Set extra skin wall count to 0 -> same result Set skin overlap percentage to 15% -> same result Set line width from 0.4 to 0.35 -> same result Then I tried to print the same object on my UM2+ Extended -> looks good, no gaps! Then I sliced the object with Simplify 3D -> looks good no gaps! The interesting part is, that the wall count defaults to 2 on the Um2Go. When I print with only 2 walls then there are no gaps! But printing with 3 or 4 or 5 walls, there are gaps, every time. Then I tried to create the Go in Cura with the UM2 profile, but same result as with the Go profile, gaps. Next try, added the printer with the UM2+ profile and yes, no gaps. The difference between the UM2 and the UM2+ profile is the line width. UM2 defaults to 0.4 and UM2+ to 0.35. But printing with the UM2 profile and manually set 0.35 line width is also not working for me. Now I also know why I only see it from time to time. I often print with defaults, so 2 walls and there are no gaps. But for some prints I need more walls and then I see the gaps. Really strange issue.... If someone with a Um2Go is willing to try it, here is the project file: UM2GO_Guide.3mf
  6. Hi Ultimaker Community, the Cura Slicer fills ab big hole in a cover plate that I want to print. It is a hole for a antenna of a orangePi Zero. I build a case for this OrangePi in blender. The strange part is that the hole is shown in the cura edit mode but is gone in the preview mode :-/ Can you pleas help me? Cura Version: 4.2.1 Printer: Creality CR-10 OS: Windows 10 LTSC 64bit orange-dach-2.3.stl blender.zip
  7. Hi, I've noticed the issue that sometimes Cura generates infill above support instead of shell. I tried to reproduce this issue by modelling a very simple part with different dimensions, which shows that the issue seems to dependent on the size of the area above the support. If the area is small Cura does not generate a shell, if the area is bigger it generates a shell. I attached some screenshots, the STLs and the G-Code. I would appreciate if somebody can give me some hints how to solve this issue. Thanks in advance!

  9. I have a weird problem with the Olsson Ruby. Printed only PLA with it and it worked fine until now. Suddenly it wouldn barely extrude and would grind down filament. At first I thought it might be the coupler. Fun fact: I haven't changed the coupler ever since I've installed the extrusion upgrade kit... So this thing was super durable. However, I changed the coupler, inspected the bowden tube, the feeder (no obstructions) and the Olsson block. It would still not work. The Olsson Ruby nozzle looks absolutely fine. Since it has a translucent tip, it is pretty easy to see through and it is completely clear. The inner walls look fine too. If I mount another nozzle, the extrusion is fine. Any ideas? Did I miss something? Btw. that's how the filament tip looks like after performing a couple of atomic pulls (perfectly clean)
  10. Hello everyone, I am having trouble with some strange underextrusion. In some prints, maybe 1 out of 10 and in only certain parts, the PLA is extruded in little pulses that increase in frequency untill they turn into a smooth line. This always happens at the beginning of a new layer, after z-hop and retraction. Due to this the print is massively weakened at these parts and shows striations on the surface. I managed to capture this on video and also have a picture of it, but I have no idea what could be causing this, especially because it only shows up every now and then. I would be very grateful for tips and help regarding the issue. Here is the link to the video: https://photos.app.goo.gl/G3TLKveMsLNRQmgv7 Thank you very much!

  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. Hi, I created a model with an inner thread using FreeCAD, exported as an .stl. The thread is displayed correctly in FreeCAD and Blender and also in Cura. However, after slicing, Cura wants to print the section with inner thread as a complete block. I tried different settings, turning support on and off, but always got the same result. Using Cura 4.2.1 on Linux Mint 18.1 Cinnamon 64-bit. Thanks for any help. test2.stl bottom-demo.FCStd.zip test2.3mf
  13. Ein herzliches hallo an alle, die den UM2 zusammen mit Octoprint ERFOLGREICH betreiben. Ich habe jetzt meinem UM2 auch einen Raspberry mit Octoprint und Webcam spendiert. Die Installation war absolut problemlos. Was aber GAR NICHT funktioniert ist das Drucken über Octoprint. Ich schreibe das bewusst hier im deutschsprachigen Teil vom Ultimaker Forum, da es doch einiges ab-zu-checken und zu erklären gibt. Das geht in Deutsch einfach schneller und besser als wenn ich dieses fürchterliche Octoprint Forum in Englisch beackern muss. Ich verstehe echt nicht warum Gina Häußge, die ja nun Deutsche ist, alles nur auf Englisch zelebriert und dann auch noch so ein fürchterliches Forumsmodul einsetzt. ? Nun gut, kommen wir zu meinen Problemen: Erstmal die Konfiguration, damit man weiß womit ich arbeite: - Firmware ist Tinkergnome seine 17.10.1 - also die letzte verfügbare für den UM2. - Octoprint ist 1.3.9 - ebenfalls die aktuelle Version. - Slicen tue ich mit S3D in der 3.0 Version - und nein, ich werde nicht updaten - als Cura Profil verwende ich ein Profil aus der Version 15.04.5 - und ja, ich habe dort auf Marlin / RepRap umgestellt. - Bondtech Extruder mit 492,45 Steps fest in die Firmware reingeschrieben Was funktioniert, was funktioniert nicht: - Als erstes mal kann ich sagen, das dass connecten zum UM2 funktioniert. Es werden Temperaturen angezeigt und Fahrbewegungen ausgeführt. Allerdings musste ich im Druckprofil die X & Z Achse invertieren, da diese sonst in die falsche Richtung gefahren sind. - Homing aller Achsen funktioniert - Gcodes senden für das Heizen von Bed und Düse funktioniert - vermutlich auch alle anderen Was funktionier NICHT: - OCTOLAPS - da könnte man einen eigenen Thread von machen, weil das Plugin immer wieder Fehler ausspuck sobald sich die Drucktisch in Bewegung setzt (angeblich außerhalb vom Druckbereich)..... und glaubt mir ich habe dutzende von Octolaps Einrichtungs Videos / Tutorials gesehen und gelesen. Ich bekomme es einfach nicht geschissen. - Weder Düse noch Drucktisch werden VOR Druckbeginn aufgeheizt (trotz gcode) - Der Extruder fördert nicht - Die LED Dimmung via Gcode (M42) funktioniert nicht, bzw. nicht richtig. - Egal ob ich einen durch S3D geslicden gcode verwende oder ob ich eine STL via Cura Profil von Octoprint slicen lasse - es funktioniert gar nichts. Der UM2 startet immer sofort, ohne Aufheizen und ohne Vorschub. Bei den gcode scripts in Octoprint habe ich das hier eingetragen: Wenn ich mit S3D Slice und einen Gcode erzeuge, wird dieses Starting Script vor den beginn des gcodes mit "eingebaut" In meinem Cura 15.04.5 Profil schaut das Startscript dann so aus: So, wie gesagt, der Drucker startet IMMER sofort wenn ich in Octoprint auf Drucken gehe - keine Wartezeit ob aufgeheizt ist oder nicht. Eigentlich müsste dann mit kalter Düse ein Skipping vom Feeder zu hören sein - nichts. Der Feeder Motor läuft ebenfalls nicht. Die Bahnen werden aber ganz normal abgefahren. Wenn ich im Vorfeld alles von Hand per Gcode oder per Setting Menü aufheize, bleiben beim starten der Druckaufträgen die Heizungen an, aber der Feeder Motor läuft nicht. Lange Rede kurzer Sinn, hat von Euch jemand eine funktionierende Konfiguration für den UM2 in Verbindung mit Octoprint? Ich komme einfach nicht mehr weiter.

  15. Hello everybody, I am using @burtoogle's most recent Cura build (20190826). I noticed that enabling the Support Fan Speed Override inhibits slicing of the model. When the fan speed override is enabled, the slicing progress bar moves to about 50% and stays there for a moment, then it falls back to 0% and gets stuck there. Disabling the fan speed override restores function. What model is being sliced appears to not be of importance. Please find attached my project file and the STL with which I noticed this error.

  16. Hello and Hi ,i have been having this problem where cure fills the shaft hole with a skin and for the life of me cant seem to fix it or remove it i have sliced it with replicator g40 and comes out ok but not great i have asked all kind of communitys to assist but no luck if anyone can help i will really apritiate it i have attached a picture of how it looks on Cura and with the Build preview Regard Matt !0 tooth sprocket (7).stl
  17. Hey all, I am using a 1mm nozzle and I successfully printed test cubes (with sainsmart flex filament). I am now trying to print a shoe insole/orthotic . the entire first layer printed pretty perfectly except some strands when the nozzle was traveling. Anyway right when the print moved to infill on the 2nd layer, the filament stopped extruding. I paused the print and reloaded the filament in and it printed a few lines more and then stopped extruding again. Help! The following are my settings and some pics sainsmart flex filament 1mm nozzle: .8mm height 1mm width 3 wall lines 15% infill print temp 220 plate temp 60 print speed 10mm/s I attached pics of the front of the insole where it stopped printing the 2nd layer, I reloaded the filament and it printed a couple more lines before the extruding stopped again. I have no clue as to why that would happen! I also attached pics of the filament after I pulled it out when the print failed. One thing to note, i tighten all the way the wheel that keeps the filament against drive wheel and was wondering if that's too much or would that affect it negatively at all? Please remember I am using a 1 mm nozzle. Thanks in advance for any advice!
  18. One of my prints came unstuck during printing and the failure caused the material to build up around the hotend. It was quite a job to get the material off of the print head and in the process I have pulled out the heater and sensor wiring from the print core chip. I have tried re-wiring it myself by comparing the pattern to other print cores I have but when I came to use it the hot end went up to around 350 degrees before ending in an error. Is there a wiring diagram of the print cores anywhere or are there any other issues I should be looking at when reinserting the wires back into the chip?
  19. When the UM2+ retracts, there is a sound (a double beep), change speed of retractions and the pitch changes. What makes that sound, and can it be stopped or at least reduced? *edit Bondtech’s ultimaker 2 kit contains a vibration isolation between motor and chassis and the gearbox itself has vibration isolation foam. https://www.bondtech.se/en/product/qr-ultimaker-2-kit/ I guess this answers my question. If anyone who has one of these installed can confirm I would appreciate it. Thanks
  20. Hello, So I have this lovely issue with my new UMS5, as I am trying to print on it, it keeps popping up this warning and pauses my print: - this error occurs both with native ultimaker materials and with other brands, - this error occurs both with flow sensor on and off - this error is driving me crazy - this error occurs with full rolls of filament Any tips and tricks are welcomed
  21. Hallo, ich brauche eine Hilfestellung zum ABS. Vorweg möchte ich sagen, das die Oberfläche der Bauteile perfekt ist. So wie ich es mir vorstelle. Das Problem ist der erste Layer des Bauteiles. Hier verschmilzt das ABS nicht richtig. Will sagen man sieht die einzelnen Fäden und kann sie unter Umständen auch lösen. Dies sieht natürlich nicht schön aus und schleifen kann es ja auch nicht sein. Ich habe mit PLA, Carbon, PETG den Gegencheck gemacht und da sind die Layer perfekt. Ich dachte zuerst es würde am Printafix liegen und bin dann auf RAFT gegangen. Das Raft sieht von der Unterseite perfekt aus. Nur das Bauteil hat auch auf dem Raft den schrecklichen unteren Layer. Ich drucke über die zweite Nozzle 0.4 Drucker Ultimaker 3 Extendet Komplett geschlossener Bauraum Haftung Printafix Slider CURA 4.1 Printer neueste Firmware Ich habe zur besseren Übersicht das Druckprofil als Datei eingefügt. Ich gestehe, das der schmale Steg der Unterseite des Bauteiles 3 mm beträgt, habe aber auch wenn ich einen Würfel drucke das selbe Layerproblem Das Druckergebnis seht ihr auf den Bildern. Ich hoffe Ihr könnt mir ein wenig helfen. Grüße Michael Michas-ABS-Einstellung.curaprofile
  22. Hello all! I have a problem with my Cura slicing. I recently downloaded the latest cura, 4.0 Beta, and started having problems. When I slice a program, from Thingiverse, the machine dwells for up to a minute on the edges and the supports. Thinking my machine was going bad I printed parts I had sliced before and they printed with no problem. I reverted to an earlier version of Cura and still have the same problem. I have been running my Ender 3 for about 6 months with no problems worth mentioning. All of a sudden this happens. I am frustrated. Can anyone provide a little guidance? Thank you in advance. John
  23. Hello, first of all, yes i read tons of articles about this and tried the solutions. i design with openscad then slice with cura 3.6.0, save it on an sd card and finally print with the TEVO black widow. the problem is every now and then i get a layer shift. thirst i tried all the sollutions, but the i started to experiment. - when i start the same print again i get the same layer shift at exactly the same location and the same shift. - when i slice again with cura there could be no layer shift or a new layer shift (this with the exact same setting in cura) so - if it is a loose pully it should happen more randomly.(even if i wanted i could not get a loose pully to skip at axactly the same spot twice at a row) - if it is a defective SD card, it would be solved by changing the card (tried 3 cards withe and without extra formatting) - if it is a setting in cura, it should happen exactly the same after re-slicing withe the same settings - if it is in the printer firmware, it should happen with every print.(re-installed the firmware, and it was the same firmware with the previous cura version wich worked fine) in my opinion it starts to look like a bug in cura, evenmore because it started from cura 3,6,0 and didnt happen in 3.5 or 3.4. now i have a big thing to print (3days printing and a lot of filament) and have to gamble will it print or shift...... and if it shift will it be will it be 0.4mm or 10 cm (both happend, 10cm overnight and we all know the mess i found next day....) anyone any suggestions? Henk
  24. Hi guys, i'm using Solid Edge to design and Cura to send file to my Ender. i've printed a lot with this setup, but since week ago my printer just stops in one place for 4~7 sec producing noise like blocked stepper motor and after that time it prints normally for some time, and again stops. First i noticed it while i changed profile in Cura from CR-10 to Ender 3. on Ender 3 profile stops and a loot of mess occured so i changed to CR-10 (on CR it printed well until this week) I didnt modify anything in my software/hardware. Some ideas or experiance with that error? Thank for Your guidance
  25. I just installed version 4.1 for Mac. I had previously been using 4.0 with my Creality Ender 3 Pro (stock firmware). I sliced a small print with 4 small identical wire clips using the same settings that carried over from 4.0. It gave an estimated time of 55 minutes to print. I started the print and immediately noticed that it was pausing for several seconds at the end of each layer for each piece. I let it print several layers to see if it was just something with the first (or first few) layers, but it continued. I stopped the print and re sliced the exact same model using 4.0 with the same settings. The estimated time was 39 minutes this time. I printed it, and it did NOT pause this time. I do not have any plugins installed in either 4.0 or 4.1. Is there a new setting in 4.1 that is causing this, or is this a bug.
