I've encountered problems trying to generate .x3g file code with file types larger than around 50mb but have scaled the print to fit in the print area. I am using a Mbot Grid II+. If anyone has a solution to print larger file types, or just hints/tips I'm all ears.
Specifically, I'm running the software on Mac OS X and it is updated. I attempt to export the file to g-code but it gives me the pinwheel and eventually quits processing before the status bar even appears. Thx, and happy printing!
