  1. Hi, i have a serious problem with our Ultimaker 2+. After moving to a new building it was not possible to print any more - no material came out of the nozzle. After some attempts i solved the first problem - the spring in the feeder was worn out. But the change of the feeder didnt help. After some further examination i found out, that the temperture was too low. I had to change the setting for PLA from 200° to 260° (!) to get some print. I went on with my tries, i changed the PT100 to a new one, so i could lower the temperature to 230..240°. Then i tried a new heater, waht didn't change a
  2. Have been printing some basic objects for a new project without any issues. Now have an object that is basically a plate with a angled cylinder. Printing consistently causes a portion of the top of the cylinder to be fractured such that it readily breaks off or is only attached with a few threads of material. Photo shows the crescent shaped piece at the left of the top of the cylinder as the odd bit that gets cut off. The intent is that the cylinder is intact to the top. Model is created in Autodesk Fusion360 and exported as .OBJ file for use in driving Ultimaker S3 printer - also
  3. I hope I am putting this in the right area. I would like to see Cura be able to switch over to the metric system using feet and inches instead of just the Imperial system (I think that is what they call it at least) anyway I use this for portraits and such and I know there are conversion utilities out there on the web but it would be nice to have that availability in the program itself. Thanks Matt
  4. Our Ultimaker S3 is continuing to have issues with filament from spool 1 wrapping around spool 2 and stopping extrusion. Are there solutions for this that anyone is using? If anyone can point me to filament guides or other solutions I'd appreciate it. I've searched the forum and 3D print repositories and haven't anything for the S3 in particular. Thanks in advance!
  5. Hi Guys Non idex printer with twin heads - is it possible to set the second extruder as a backup in case the first head blocks/jams/runs out of filament? Many thanks!
  6. I started printing with Gizmodorks PVA filament and it says to NEVER print their filament above 200C because it can cause permanent damage and it causes stringing. When printing I noticed that there is an limit that they have put on how much you can offset the temperature of a nozzle (+-25C). Could you make add a setting for advanced mode where you can edit this settings at your own risk?? I am not pleased that I paid orders of magnitude more for a "professional" printer, but have less control than my previous hobby Ultimaker. -Alonso
  7. Today I was going through the Ultimaker maintenance schedule. I noticed that information about the lubrication of the lift switch was missing. That made me wondering about any need to reapply lubrication, especially since the switch is visibly lubricated. An extra section about the lift switch lubrication (or a remark about the lack of any need to reapply lubrication, if that is the case) would be helpful.
  8. Don’t know if my thoughts bounced forward or it’s just people still trying on it yet. there’s heat treating method on 3d printing called annealing, which saids will shrink the print size by 5% and make it much stronger. then than that, I was thinking about, can the annealing just build into the printer, for it don’t need high temperature, I checked the maximum bed temperature, it’s 120°C, and it’s just enough for it. the things need to make this method appear, is just a case, which other stuff already exists. The programming just need a special default setting, increasing the size by
  9. Hi, long time Cura user, infrequent poster. I understand the point of vase mode (or Spiralize Outer Contour as it's called here) - to extrude one continuous stream of material all the way around and up the part. But it occurs to me that, since there's a seam anyway (for layer transitions), couldn't there be two walls as well? Have the extruder move around the inner wall, then go the outer wall (at the seam), and when progressing to the subsequent layer just move back to the inner wall (again at the seam) and repeat. Could theoretically make an entire vase-shaped part with two wa
  10. Cura by default includes G-code for two start lines to prime the nozzle before printing begins. The settings for these start lines are part of the start script G-code for the printer and are therefore unaffected by any changes made in the regular "print settings". I recently upgraded from a 0.4mm nozzle to a Volcano setup with a 0.8mm nozzle and initially experienced that my extruder could not force filament through the nozzle when I started a print - even though I had just loaded filament and watched it ooze from the nozzle. Turns out the problem was that even though I had updated the
  11. Hello! I am looking to understand how the "make overhang printable" feature works in Cura. Any suggestions on how I can get to the source code that implements that feature? I understand that Cura is open source and the source code is available on Github, but I am having trouble finding the appropriate location for this part of the code. I am a PhD student and would like to implement a similar algorithm for my research. Apologies if this has already been answered elsewhere, but I looked and couldn't find anything. Would really appreciate any help!
  12. I love Cura overall, great software, I have recently needed to upgrade to M1 Mac as my last laptop died. I seem to be having a bunch of issues previewing models if they are even a little complicated and if they are moderately complex or worse they will crash the entire application. I know there likely won't be many M1 users for Cura but if there is a beta program I could participate in that'd be awesome, otherwise I am excited for when there is eventually an ARM compatible version available. If anyone has any suggestions on how I can get it to run better (Like using Crossover and t
  13. hi there I'm using SolidWorks since years and got a 3D-Printer some weeks ago may I'm wrong but to me STL look like a bitmap-stack without knowing that curves exist I don't know if Cura (internal) knows about curves and roundings but my printer does and my SolidWorks also! sure I use the SolidWorks-Plugin but in background this also just creates an STL and not in best quality (event I didn't got it done with absolute minimum tolerance-settings) if I export the STL from SolidWorks with minumun tolerace-settings it looks round in Cura (but i know it is not and my STL grows to 250
  14. I am using Ultimaker S5 last one and a half year, to be honest it is fantastic device. I just updated cura software and the camera is not working. How I can fix this issue?
  15. Hello, A feature suggestion to make faster and better looking prints is to adjust layer height on visible surfaces while leaving layer height on inner surfaces. In the cura preview this is red in color that I am suggesting to adjust for finer layers. Example, with a 0.8mm nozzle one could have inner print areas at a layer height of 0.6mm while setting the visible surfaces to 0.1mm. On a layer change cura could adjust the layer height and print the visible (6 layers in this example) at 0.1mm and then continue from that final nozzle height at 0.6mm for inner areas and i
  16. Hi, I'm new to 3D printing and I've been trying to print scale model cars but for some reason the windows wont show up when slicing and many of the layers will simply disappear. I'm attaching the file so anyone can see it. Thanks in advance for your help. F10 M5 Chasis.obj
  17. Printer: Ultimaker 3 Current situation: After finishing a print and removing it, the printer requires you to push the clickwheel to confirm the "print removed" message, otherwise it is not possible to start another print. This is a sensible safety feature. The problem is that people are forgetful. It is not possible to trigger the message remotely, which means that you can't start a job remotely either without somebody being physically present to push the button. This ends up wasting a lot of valuable overnight and weekend printing time, when there is nobody present to pu
  18. I'm trying to get a printer with two extruders to print separate objects but cura always wants to assign one of the heads to do all the supports. Print settings - Support - Generate support (ticked) - Support extruder etc is then locked to one nominated extruder Is there any way to unlock it? Thanks🙏
  19. Hi all🙂 Please be gentle, quite new to all this, but was hoping someone could help with setting up cura for a craftbot idex xl Any help greatly appreciated!
  20. Hi! I am currently trying to control my Ultimaker S5 via the Api. "Get" Requests are no problem in my c# skript, however any requests that require a authentication are impossible. In Python it is quite simple, you can just use a library that does the digest authentication for you, however I spent almost a week now looking through the internet trying to get this to work in c#. Has enyone an Idea on how to approch this or has expiriance with that? Any hints would be much appreciated! All best, Varrick
  21. Our Horizontal holes are now being sliced and printed as slots. Looks fine in the prepare screen but in the preview the holes are slotted.....and it prints that way. This just started in the last couple weeks. We use autodesk inventor to create our parts and export to STL. Please see example below. Thanks
  22. Hi guys - been using cura for years with my Ender 3 - its been fantastic. Depeding on a number of factors (quality of filament/humidity/randomness) after my initial purge line prior to starting a print, there is sometimes some seepage out of the nozzle or a bit of stringing that goes on, often leading to a string of filament or a blob being dragged across to the start of the print - which is OK when running a brim or a skirt for the most part - but sometimes it gets under the start of a print and causes some irregularities - would be nice to have like a 5mm lead into the start of the print
  23. So I use an Ultimaker S5 Pro bundle at work, and have a Prusa MK3 at home. The one feature that I really wish Ultimaker had (that is on my Prusa) is the live Z adjust - Prusa lets you twist the input nob to adjust the Z mid print by .1mm per click of the knob. What's super nice is that it adjusts at a controlled rate across the entire bed vs. trying to twist the adjustment knobs on the Ultimaker and hope you keep the bed level and you have no idea of exactly how far you adjusted. Ultimaker could build it into the firmware so there was a menu you could access during printing that l
  24. 1. The ability to create our own profiles for the Material Station. I have some MatterHackers Pro nylon that prints great but hangs up when the material is pulled out of the print core at the end of the print. I think all that is wrong is that the core needs to be at a higher temperature. It would be nice to be able to fix this myself. 2. The ability to disable one of the one of the "inputs" from the Material Station and feed that core directly from a spool on back of the printer. So core #1 would get fed from the Material Station and core #2 would get fed from a roll on the back
  25. We really enjoy the mobile app notifications for started/completed/aborted print jobs in Cura. I recently noticed that there is even a notification for an improperly configured print job (wrong core/material). What we would REALLY like is a notification for a print job that has been paused for whatever reason - particularly jobs that have run out of material. This would be so helpful and it seems, to my naive mind, would be very simple to implement. Can this be done via 3rd party plugin now?
