I have a very odd issue that is also random but only happens when slicing with Cura. After a print has finished sometimes the machine goes to it's far extremes causing the dreaded clicking. Even the filament sometimes reverses, it's almost like everything has suddenly reversed. What is odd is that sometimes it doesn't happen. If I use S3D or Prusa Slicer etc I have no issues, exactly the same start and end g-code, Marlin etc etc. Any ideas?

    It sounds like something is going on with the End Gcode when it switches to relative extrusion and/or relative movement.

    Copy the ending gcode from the Cura machine settings (you will have to use CTRL+C) and paste them into a post here.

    Cura uses it's own "keywords" and curly brackets where PrusaSlicer keywords are in square brackets.  So if there are keywords in the ending gcode there could be problems.

    The fact that it "doesn't happen all the time" is troublesome and might point to the firmware.

    Has this been going on long?

    What printer are we talking about?
