Problem sending files from mac to topwisdom

Running Big Sur 11.7.10 and the newest version of lightburn. Can only send very simple files to machine. If they have to many details it looks like its sending, but machine does not receive file. Machine control works from software. Please help.

Can you describe your process for sending files?

Have you tried clearing the memory of your controller?

How large are the files that aren’t being received?

If I make a simple design in lightburn, maybe a circle and press send, the files is received on the machine.
If I make a more complex design, maybe 50-100 circles or squares and press send, a window with a blue bar comes up and it looks like it’s sending, but the files does not appear on the machine when it should.

I have tried to clear the memory on the machine and deleted all the files.

I believe it works well with files under 30-50kb.
