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

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

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

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

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.

Thanks for the 3.0.3 I'll load and see if that is OK.

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?
