Groping my way forward

[Britannicus1]

Hi - I'm slowly starting to understand some of the basics in CNC - but I'm still not quite there :


I have now gone as far as creating an image and successfully simulating the cut i want to try in Fusion - I even managed to generate G code from that

1001.nc

Unfortunately when I load this to my CNC controller (my machine came with USB CNC) - it refuses to load with a message it didn't understand line 1 -

Now - if I take the file and load it to "quick and dirty g code simulator" - this shows a number of lines in the code it doesn't understand and the simulation is rather different - see screen print



The only help I can find in Youtube - seem to use mach3 as a tool and seems to need some amendment of the code - can someone help me to get the code to load ?
