Thats only a small section. I had already removed G64 when i copied it.

i put into mdi what you said and still no luck. For what it is worth the machine runs smooth and fast when i run an example provided which is a spiral. the spiral's code is lots of radius's not lots of small lines like the above

Ok well maybe this is why folks return to Mach3 so then the solution is Mach3. . .

So the question is how do you make cambam output radiuses for curves instead of lots of straight lines? Ive been into the postprocessor and tried all options relating to curves, it outputed exact same code though.

and no mach 3 for me!!!!

This might be a question for the linuxcnc forum ..Clive
