    Cura crash backup

    Nice one, found it! Now to load back my settings in Cura, do I just place the zipped files into my configuration folder?

    Cura crash backup

    Hi, my Cura (3.6) kept crashing on startup, the error message gave me the option to "backup and reset configuration", which got it working again. Now I'm just looking for the mentioned backup. Can anyone tell me where it should be stored?
  3. I have had this same problem over the last few versions of Cura as well, so: Bump!
  4. Printing multiple objects one at a time doesn't seem to be working as it should, or at least as it did. As you can see in the image, the "shadow" for the print head is way larger than it used to be. This means I can only print three of these objects where I used to be able to easily print nine of them (the last few versions of Cura did require some manual adjustments since prints did get hit when using the spacing set by Cura). I have this problem with UM2, UMO and UMO+. It seemed to me the print head is set way to big, but the settings are realistic. Is there some setting available that lets me change the safety margin?
  5. I have this weird issue with horizontal bands showing up in my print, and am hoping someone can shed a light on the reason for this. I'm using a bit of an unorthodox nozzle size and leyer thickness, but I don't think that is what's causing the issue. I am printing on an Ultimaker Original+ with a 1,8 mm nozzle. My layer thickness is anywhere between 0,4 mm and 1 mm. Print speed from 20 mm/s to 38 mm/s (I make all speeds equal in Cura except for the initial layer, to prevent large pressure changes in the nozzle). I am printing in spiralize mode. The filament I am using is HiPs. As you can see in the photo that I have attached, I get some pretty obvious horizontal lines over the printed surface. I tried messing around with different speeds, layer thicknesses and acceleration and jerk settings, to no avail. I took a real hard look at my layer preview in Cura and discovered that the horizontal lines are actually present in the preview and can bee seen in some angles (second image). I also noticed the location of the lines changes when I use different layer thicknesses. I think the lines show up every thirteenth layer, independent of layer thickness. Can anybody tell me what could cause this issue? And maybe more importantly, how to fix it? Edit: The problem doesn't occur without spiralize contour being turned on. However, I would like to spiralize, because of the z-scar...

    Wrong line width calculation

    I think this problem was fixed in Cura 3.2, but it seems to be back in 3.3.1.

    Introducing The Experimental Bridging Settings

    In this example I think the bridge is detected, but the line direction isn't optimal. I can fix it by choosing a top/bottom line direction, but that also changes the bottom of my print. Maybe a seperate line direction for bridge layers would be nice in a next iteration? Although it wouldn't work for all models.

    Introducing The Experimental Bridging Settings

    I have added some arrows pointing to the lines that I mean in the image. They "close off" the area of skin that is the bridge and run perpendicular to the bridge. As I said before I do not think they are very important for the end result, but I can't stop myself from wondering why I have a different output. I'm using sparse infill since I'm only interested in the bridging behaviour, but as I will try the expand skin option, I will add some more infill for my bridge to latch onto. I have tried bridging on different speeds and noticed improvements every time I slowed it down further. Now I arrived at 10 mm/s and Cura will not let me go slower. I'm curious to try going even slower, if possible!

    Introducing The Experimental Bridging Settings

    Thanks for the feedback! Will try the skin expand setting soon. As for the "walls", I meant specifically the ones that run perpendicular to the bridge, connecting all the bridge lines on the far ends of the bridge. As they will be on the inside of the model, they are not really wall lines, but I didn't know how to call them. I don't think they are there in your image. Would you also know what the coasting percentage means? What is it a percentage of?

    Introducing The Experimental Bridging Settings

    I am very pleased to finally have some settings for bridging to tweak! I have been playing around with them and getting some pretty good results. I was wondering something about the image above. The bridge lines in the image seem to extend into the infill, while mine will only start from the underlying walls. It seems useful to me to extend the bridge beyond the walls, but cannot find a setting that controls this. Also, my bridges are surrounded by wall lines, where the ones in the image are not. I don't think this matters a whole lot, but I am still wondering why I am having a different result. Any tips?

    Wrong line width calculation

    Awesome, thanks for the feedback!
  12. I'm using Cura 3.1.0 with a bunch of Ultimakers (O, O+ and 2) and I am having a problem with the line width setting for the UMO and UMO+. It seems the calculated line width is always 0,4, even when I have a different nozzle size filled out in the machine settings. When using the UM2 (with olsson block) the line width updates when I change the nozzle setting, but this setting isn't available for UMO machines. I have a bunch of machines set up in Cura with different nozzle sizes, none of them translating the nozzle size to line width, resulting in failed prints because I am not used to have to set this manually. I think it used to work fine in previous versions of Cura The help dialogue states the setting is affected by "nozzle diameter", while I only have the "Nozzle size" setting available (or just "nozzle" for UM2). I would think this is the same setting, but apparently there is a difference. Does anyone else have this problem? Or does anyone know where to set the Nozzle diameter setting?
  13. I have this ultimaker 2 (added olson block and using Ultiarjan's extruder), which failed to heat it's bed without giving an error. I dissasembled the bed, to find nothing wrong. So I dug on, exposing the motherboard, to find the PCB terminal block connecting to the power wires was completely burnt out (see pic). Image I suspect a faulty connection was the culprit but I am really not sure. I now have to repair the printer and have two questions to which I cannot find a clear answer (had a phonecall with ultimaker support but they were not sure either). How can I know if the heated bed itself is still usable? I have three of them lying around, one which definitely works and two that are suspected to be defective. I measured the resistance over both the heating element and the sensor (removed beds from printer/power supply & made sure they were room temp). All three of them return identical values, about 3 Ohm on the heating element and around 110 Ohm on the sensor. Are there any other measurements I can perform to tell me anything about the status of the bed? How can I find out if the motherboard is lost? I have some spare PCB terminals of this size lying around, maybe I could just replace the terminal on the board and see if it still works? If anyone has any tips on finding out if my components are still usable, they would be greatly appreciated!
