What is the text in the box at the bottom of the screen with a red X say? It's too small to see what is there. Any other errors pop up when you attempt to run the G code file?
The screen shows the intended tool trajectory so I would ask two things;did the operation run without problems when simulated in Fusion?Second,did you choose and configure the post processor correctly?I can't offer too much help because I use Freecad and the interface on my machine is the standard Axis version of LinuxCNC.
I have a strong suspicion that the line causing the trouble is N25 T3 M6.If you don't have an ATC (and most of us don't) the machine won't know how to handle this command.I suggest you delete this line and try running the sequence WITH NO TOOL INSTALLED AND NO MATERIAL ON THE BED OF THE MACHINE. If it runs as intended,you would then be able to do it for real.
