I just need a arc that runs into a bore to create a bellmouth for the intake for a small jet engine sound simple enough. But for some reason not so.
My Lathe is in Radius mode.
The bore is 38.9mm. dia. the arc has a radius of 11.800mm. The arc starts at X27.535 Z0 which is where I position the cutter before commanding the G03 and ends at X19.450 Z-11.200 so my centre offsets are X3.715 Z-11.200
So My Gcode is G03 X19.450 Z-11.200 I3.715 J-11.200
What I get is the error Start=(X27.535 Y0.000), Centre=(X31.25 Y-11.200), End=(X19.450 Y0.000) r1=11.8001 r2=16.269
First thing is why does the error show Y instead Z when I'm in lathe mode.
Second whats wrong with my Gcode.
I tried to put this on the EMC2 forum but kept getting error in email message.
Any ideas Thanks Rod
