Cannot send file via USB cconnection

[RLGL]

Flashforge CreatorPro2 connected via USB. The machine is connected and I can control it with the machine control panel. If I try to begin printing on the machine I get an error, cannot read the file. Is there something I can change or will this require S3D update?

Hmm.. sounds like it might be a problem with the file. Can you try uploading a .gx file that you have already successfully printed in the past? That way it's only testing the USB communication.

It's not the file. I exported the file to disk. The resulting export was two files, a .gx and a .gcode. Transferring each file individually (via a file manager) to the SD card finds the printer is able to read each one. That leaves something with the software's ability to move the file via USB as the cause. FlashPrint is able to communicate with the printer via USB.
