Recently whenever I slice files on any version of cura (I have tried previous versions) any straight lines are instantly completed. I looked at the acceleration and jerk controls and even tried turning them both down to 1 mm/s and print speed down low as well. That didn't fix it and I loaded up an old gcode file that I sliced before I had this issue and when I looked at the preview it somehow changed those straight lines to be instantaneous as well. Any ideas?
