First, I'm very new to this (Only printed about 4 things so far). In the past I've used the Cura 15.4.02, and the previous version of Cura (2.7 I think?). Prints were fine, but I didn't do much tweaking. Now, I'm trying to tweak, and I updated to the latest Cura 3.0. Now, everything I try to print that was sliced with Cura 3 just sits there. No movement whatsoever. Printing older files work fine, so I'm guessing it's a gcode issue caused by Cura, or possibly some tweak. Here's the start of one of the files. What am I doing wrong? Thanks!
