Trying to fathom cambam

[John11668]

So am trying a few simple exercises in Cambam (nearly used up my 40 goes )
I selected a piece of stock (as a nameplate )
Then Super- imposed my house name onto it.
Selected to engrave it, put in a few settings , (4 passes at 0.2 mm each) and selected Mach 3 post processor and clicked to produce G code .
Seems to generate a decent toolpath so had a look at the G Code and copied it on to a stick and carted it off to the workshop to see the result .

Works Ok in Mach 3 mill and doesnt throw up any early error messages , even starts to cut letters, until it needs to raise the tool and move at which point it goes off into a large anticlockwise arc . It wants to do this every time so the result is slow and the arcs would take the head way off table.

So what do I need to do to get this going as it should ????
