4th axis and fusion 360 problem

[amxen]

stops at 490 line every time here

What speeds and feeds have you selected in the F360 CAM settings tab? In your screen shot, the machine speed drops right down at the line marked, where there is a significant move in A.

I'm probably talking the proverbial... but 490?, your Mach3 installation is licensed?

[amxen]

Yes it's I'm running some more code and it's still doing the same thing but at line 234

been trying to get this working for over a week now . almost giving up on it

Both examples that you show freeze with very slow feed rates (F554/F373) compared to the preceeding gcode - can you confirm that these lines do indeed have the lowest feed rates upto that point in the gcode?

If so, add a zero (x10) and try an air-cut, see if the behaviour is the same
