GRBL file to controller over ethernet

I have my design software located on a computer on a home ethernet network. I also have the OneFinity controller also on the same ethernet network.
Can the Onefinity controller access the Grbl file on the computer or can the computer send it to the controller? Don’t want to use the thumb drive unless I have to.

You can connect to the onefinity, via the PC.

use; http://onefinity.local on your pc, and upload files using the folder icon near your start/stop/pause controls.

You can only upload files when the machine is not in use, ie; not jogging, or running a file. I would suggest uploading as many, or all, of your toolpaths if you can, prior to initiating the first one.
