  1. Time for another update! This issue recurred again but it's September in Scotland and a cool steady 17 degrees C in the house, plenty of printing being done successfully but once again on large flat bottomed prints the same issue. OK so after a few Cura updates the print temp had reset to 200 degrees C but in the normal course of printing this was not a problem. Then a project with a large bottom surface area came up and the same again. This time when I tried to extract the filament it got stuck in the Bowden tube because the piece from the hot end had got excessively thickened aft
  2. Hi, I wanted to update this thread because I've recently had the exact same problem and came by a solution that allowed me to continue printing. To cut a long story short it was the same issue - suddenly all my prints failed shortly after starting with grinding. Although later I did establish that prints with a much smaller X/Y travel worked fine. I re calibrated everything, tried different high quality filaments, replaced Bowden tubes and nozzles and used both extruders. (UM3+). I came by this thread and was intrigued by the proposed route cause
  3. This has happened several times now and is becoming rather frustrating wasting both time and material. Often when I send a new job to the printer it just goes ahead and reprints the job it did last. Today it did it after a cold restart of both the printer, the PC and obviously Cura. It can happen at any time after an aborted print in which I am careful to select NO to retry? It can happen after a fresh start or after successful completion of a job when I send a new job. Today despite having cleared the printer last night and "removed the print" when I fired it up the "print removed" query
  4. Add "--single-instance" as a command line argument to Cura.exe in Fusion. Thanks for this, could you provide a bit more info on how to do this? I can't find anything I can edit this into within Fusion??? Maybe a screenshot if possible
  5. There is no change and this problem still exists. From the Fusion end I am able t select Cura as a custom 3D print app. But in doing this every model I send to print opens a new instance of Cura.
  6. I'm in the middle of migrating my work from a Mac running the latest OSX High Sierra to a Windows 10 PC. My 3D design platform is Fusion 360. When I installed Cura 3.0.4 on the Mac and tried to send a object I got the message that this version of Cura was not compatible... so I reloaded 3.0.3 and all was fine again. Now I'm working on the PC I've loaded up 3.0.4 and when I send a file to it from Fusion nothing appears in Cura. Unfortunately I cannot seem to find 3.0.3 to install and try. Anybody got any ideas or similar experience?
