G-code stalls

Hi,

I am generating G-code with Fusion360 and want to engrave something.
I prepared test file H.ngc which is supposed to engrave letter H.

But when I run it, machine just moves to the home position and then is hanging there.
LinuxCNC does not throw any error. It looks like it is waiting for some line to execute.
The other test files work fine, so does the hardware.
The tool is in tooltable.
So I suspect the gcode (attached) is wrong in some way but I do not understand it much.

Any help would be appreciated.

Thanks in advance
Jiri

Just to be sure, do you have tool number 70 in the tool table ?

Yes, I do.
It notified me when I did not, I added it afterwards.

Okey,

there was a other problem with manualtoolchange component.

What was it ?
