Job freeze on simple G0 Z5

Hi everybody,

I just started using a 3 axis CNC (YXZ).
The workflow is Fusion 360 >  EMC2 > LinuxCNC

I tried a simple job doing with 3 holes, here is the G-code:
The job freezes on "G0 Z5." witthout failing (no error messages, the machine is idling, the spindle is still turning).
At first I thought the issue came from "G43 Z10. H1" or "T1 M6" since I haven't setup a tool table, but it has no effect on the job.

Deleting "G0 Z5." makes the whole job run smoothly.
The same issue happens on all jobs processed by Fusion.

Here is the beginning of a job created on Estlcam that run without freezing on the same machine:
Why does the first job stop but not the second?

I just tried "G43 H1" without any difference.

Does the commands orders have an impact with G-code?
For exemple is "M3 S5000" different than "S5000 M3"?

I solved a similar issue, to cancel cycle81 or canned cycles

Thanks, I'll try that tonight.
It seems my issue is related to my Mesa - LinuxCNC setup involving the Z-probe.

Problem solved, the spindle wasn't rated for 5000 RPM ...
The spindle would start at "M3 S5000", but it automatically stopped at "G0 Z5".
