Maximum .stl file size in mprint?

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!

I have the same setup.

Have any links to files for me to test?
