  3. Get our crap together? Excuse me? You're using an open source product, on hardware that we don't sell or support. We don't even have those third party printers nor the capacity (and desire) to actually test them. So if you want to prevent issues like that, pleas use the beta and report these issues during the beta. As you can see, i've managed to create a fix for this within a single hour of this being reported. We test Cura as much as we can, but we greatly focus on Ultimaker machines since 99% of the development of Cura is paid from the revenus of Ultimaker.

  4. Thanks you. After some tests, trials and errors, I can now print whit the accuracy I need ! The settings I use are the one above with jerks at 20, retraction at every layers. I use the engineer profile at 1.5. Now my prints don't expand. The settings that help is Horizontal Expansion : -0.16 (For Ultimaker PLA Tough and Ultimaker PLA) Hope it help others as well. I got scared for a while, but the problem was the guy in front of the printer not the machine.

  5. Yes, I got the same problems, and only now found the solution. Just change the thickness of the filament from 2.85 to 1.75 in the settings. Of course it would help only if u use 1.75 mm filament.

  8. The newer firmware works with weak spring and with stiff spring. Replacing the spring is not necessary, but feel free to do so. The behavior you describe is of course not how it should be. You may want to reach out to your reseller, they will be able to help you. How is your bed positioned? I always make sure the bottom of the glass plate is slightly (0.5mm or so) higher than the top of the alu at the front. The screw on the back must be adjusted so that the bed is parallel to the gantry (I do that by manually raising the bed, and then manually move the printhead from front to back

  10. Your start gcode does not include any commands to heat up your extruder or your bed. Cura sees this, and tries to help you by adding a heatup sequence before your start gcode. This is handy, but not flexible. Here's a sequence that first heats up the bed and hotend, but uses the "standby temperature" that is low enough that no oozing will happen. Then it does the leveling, before heating the hotend all the way up in time for priming. ``` M201 X500.00 Y500.00 Z100.00 E5000.00 ;Setup machine max acceleration M203 X500.00 Y500.00 Z10.00 E50.00 ;Setup machine max feedrate M204 P500.0

  12. Did you re-slice the model and try to print the new Gcode file - or did you run the previous Gcode that worked? Within the printer under Control / Filament make sure "E in mm³" is "Off". Looking at W1_underextrude.gcode in line 4 it says it uses 20.868m of filament. Dumping the file into AutoCad I come up with 505720.78mm of extrusion and a total E of 20.89mm. So that's whats going on in the Gcode file. With an initial layer height of .2, a layer height of .25, and a line width of .4 and doing some math (sorry grNadpa) then layer 1 is 16020.78mm extrusion

  13. I generally respond to those pings, although I don't track issues on the forum itself. If you seek to modify the layer heights, look for the buildLayersWithHeight function of the Slicer class: https://github.com/Ultimaker/CuraEngine/blob/51ee4b7adf6dfd112241cdf3fd5681e87cf6370c/src/slicer.cpp#L929 In this function it determines the Z coordinate of each layer, either by calculating from the layer height and initial layer height, or by asking the AdaptiveLayer class.

  14. /facepalm Thank you good sir, I was certain there had to be an option for it somewhere, but for the life of me i couldn't find it yesterday lol. Was already doing the manual rename, but forget every now and then. Interesting to know, thank you again. Cheers Nallath, I went and found a plugin by fieldOfView (aka ahoeben on forum ?) called "Custom Printjob Naming" that works precisely as advertised.

  15. Got it. In my haste I missed the change button. This is the second spool we finished fo far and we have not yet really changed spools so never used the change feature. Thanks for your reply, this issue is resolved and the printer is happily printing again!

  16. Hi, You don't press the unload button when you have run out of filament, when you run out of filament and the prints auto paused you go to the filament thats run out and press the "change" button to change out the spool. The unload button is for just removing a spool and not loading a new one for when you are printing and only needing one print core so you can store your other spool somewhere. The load button is for when you wish to load a spool back onto the printer. This is why both the load and unload are greyed out when printing. When changeing spool always use

  17. Hi guys, After years of following the evolution of the mark2 project, I finally got my hands on relatively cheap second-hand Ultimaker 2 (non plus that wasn't in the best shape to be honest) and did the upgrade a week after receiving the machine! As a UMO veteran - not even the Ulticontroller was around when I first got my machine xD- I am super amazed how well the mark2 does! While I have been playing around with the original dual extrusion upgrade, I must say that the mark2 is lightyears ahead in every concern!! I created a magnetic head for my e3d-hotend that I'll be sharing

  18. I guess the root cause for your problem is that the fan in the back is not running or is blocked. This fan cools the upper part of the hot end. Check if the fan is working when you heat up the nozzle. It should start automatically when the temp of the nozzle is higher than 40/50C.

  21. Holes like to come out undersized. The plastic is viscous enough that it gets dragged towards the center as it extrudes. @gr5 calls it the "Snot Factor" and the smaller the hole the worse it is. Under "Shell" you'll find "Hole Horizontal Expansion" and it will get you much closer. It is an offset setting and so it acts on the radius. Your diameters are off by about .8 so set the Hole Horizontal Expansion to .4mm. Another thing - is that image of the part accurate as to the resolution of the STL file? Check in TinkerCad and see if there is an option for a higher resolution when i

  22. Open %APPDATA%\cura\4.7\cura.cfg in a texteditor (eg notepad). In the [general] section, remove the lines starting with window_left and window_right Save the file and try starting Cura again. If that worked, go into the General preferences and uncheck the option to "Restore window position on start".

  27. I have created a plugin that lets Cura access HID mouse devices such as the 3Dconnexion Spacemouse. It's called RawMouse because the plugin interfaces directly to the raw device without the aid/hinderance of an operating system driver. It's not a sophisticated all-singing, all-dancing interface, it simply converts the HID mouse commands into the equivalent 2D mouse commands. It has been (vaguely) tested on Linux and Windows 10 and it should also function on MacOS (10.13 upwards). For a quick install, unzip the latest RawMouse.zip from https://github.com/smartavionics/

  28. On the left of the Cura workspace screen is a toolbar. The bottom tool is "Support Blocker". Select your model and then select Support Blocker. Click somewhere on the model to create a block. On the lower left there will be a list of the objects on the build plate (oddly enough called the "Object List"). Your new support blocker will be Eraser and additional blocks will be added to the list. You can make them active by selecting them on the list. When you select the Eraser block you can drag it around or type numbers into the Move tool dialog. You can also scale it separately i

  29. If users of 3rd party printers aren't willing to try the beta releases, they should expect trouble when the releases arrive as UM do not have the resources to test on anything but their own products. Yes, Cura is supplied FOC but maybe people need to be willing to pay a price for it, the price is that they play an active role in the testing of new releases.

  31. Well, there is a reason why i fixed the bug. It's not like we don't care at all about what third party printers do / work with Cura. But well, there are hundreds of printers available in Cura. If we would need to test all of that, we'd need 20+ QA engineers. At a certain point, there is an end to the amount of money that Ultimaker is willing to invest into support third party printers. That value isn't zero, but it's obviously not the same as in our own printers. I guess my frustration with all of this is that the bug was blatantly obvious to someone who had that configuration. But even tho

  33. @gmeardi If you can love the solution depends on how much you are willing to stretch 'easy', so here we go. Before working with the Ultimaker S5, I've never really put my mind to NFC technology, so there are very probably some gaps in my understanding. Most of what I've learned, I've deduced from comparing the data from different spools and with different amounts of remaining material. The rest I could fill in reading the relevant python code of the firmware after ssh-ing into the printer. As @Daid pointed out earlier, Ultimaker tried to implement NDEF records. Accordin

  34. Small python tool that helps adding 3rd party material to Ultimaker S5 on-display material type selection. https://github.com/flyinggorilla/ultimaker-s5 I do like the NFC enabled Ultimaker filaments and I am impressed how easy printing with the Ultimaker S5 can be. However, ordering filament through third party vendors is always a challenge, because they usually have only a fraction of filaments in their stores. Also do my use cases go beyond Ultimaker filament material types. So i complement Ultimaker material now primarily with FormFutura material (they have a great o

  36. I would check the front cooling fan is spinning and working right if the filament had grown a ring around it outside of the print core, as you might have had heat creep due to front fan not working/spinning free.

  37. Hi - I have what I think might be a dumb question but I haven't been able to figure it out... I have a Prusa Mk3s. I've switched to Cura 4.6.2 and I'm trying to get time remaining to show on the LCD during prints. I've gone to Extensions->Post Processing->Modify G-Code and select "Display Remaining Time on LCD", enabled it, and then sliced. Still, I'm not seeing any changes on the LCD and it continues to show elapsed time. What am I doing wrong here?

  39. If you use the printer normally, through menus and such there is no difference in developer mode. You are fine. But if you ssh into the printer and start editing files then all bets are off. As far as sendgcode breaking something - it's almost impossible. But I suppose if you are clever enough you *might* be able to break something. I can't think of anything though. The printer has temp limits to keep you from going too hot and the steppers are not strong enough to break anything. A bigger issue for some people - if your printer is out on the internet th

  41. In DesignSpark Mechanical there are 3 standard quality-options for export to STL: coarse, medium, fine. I use the fine, which gives about 2x to 3x more triangles than in your image (which corresponds to about medium). Custom quality allows for even better, but that is overkill: the printer can't follow too fine details anyway. But there can be lots of other reasons why accuracy is not great: extruded flow too much or not enough, nozzle too hot or too cold, blobs, incorrectly callibrated X- or Y-steps per mm, printing fast so corners get too thick when it has to slow down suddenly a

  42. That is a first for me as well. Just as a hypothesis - I can see a couple of scenarios here that might have the potential to trigger an unexpected print. I have two different computers (laptop and desktop) that I use Cura on, both on the same network as my UM3's. I have accidentally suspended operations on the laptop by closing the lid too early, only to have them resume when it opened. If there was an upload suspended at an opportune time, maybe it would resume? I have also had uploads that hung up during a session on the desktop, only to try and complete

  43. I am glad it worked! The queue itself is not in Cura, but your printer has a queue of print jobs. Could be more complicated if you use the cloud or a group host, but basically the printer has the queue.

  47. Actually, here ya go. Attached are all three profiles I have already pulled from their Dremel Slicer from about a month or so ago (3D20, 3D40, 3D45). I just upgraded to 4.7 and they continue to work fine. (Had to zip them as this forum didn't allow me to upload json files) You'll want to place them in your Cura's install directory, under the "resources/definitions" folder: Windows: C:\Program Files\Ultimaker Cura X.X\resources\definitions Linux: ~/.local/shared/cura/X.X/definitions/ (replace X.X with your version) Note: I don't use the attached 3D20 profile but instead I u

  50. Evening all, I have recently got a 3D45 and whilst I know it comes with its own Dremel slicer which is based upon the Cura slicer (I assume its an older version) I am wondering if any of this community have got it to work\connect and slice from Cura. I'm keen on using the latest version of Cura has I believe there are significant feature improvements\enhancements over the supplied slicer. Any help or guidance will be most welcome and am aware of the 3d20 plug but have just tried that and not been successful. Darren
