Jbirch,
I use Easel Pro 95% of the time for my designs, you need to click the "advanced tab
Then: Generate Gcode
Then just Hit the Export GCode button and save it to either a flash drive or a network drive which then on OneFinity you can open the file and hit print. Make sure you Probe Zero before you “Play” as the code that Easel Pro generates will not trigger the probing. You can add code to the file if you’d like to have it probe first but that’s a different discussion if your interested
Hope that helps!
