I take a different approach by opening my toolpath export files from my Onefinity using a shared network folder set up inside the Linux OS on the 1F. Technically, I use my network storage server (NAS) to manage all my CNC project files and toolpath exports. This setup allows me to edit files either on my office desktop computer or my workbench laptop. Then, I simply go to the 1F, click the Open File button, and navigate to the same network folder to access my .ngc files.
One great feature of the BB controller is that it defaults to the last folder opened, making it quick and easy to find the toolpaths for any project I’m ready to carve.
Even if you don’t have a network storage server like mine, you can still edit and export files on any Windows computer you prefer and use the 1F to browse to them.
Here’s a link to some instructions I wrote a while back that should still be relevant:
