Re: Arc resolution in EMC

Hi Barry,

I had the same problem a while ago.
Look at src/rs274ngc_new/rs274ngc.hh at the beginning an decrease these 
values.

/* numerical constants */
#define TOLERANCE_INCH 0.0002
#define TOLERANCE_MM 0.002

Once you have changed them => recompile.

Could somebody please but this in the handbook. It keeps coming up every once 
in a while and costs time for almost everybody who uses generated gcode.

>Seems to me this should be a configurable setting. 
I agree with you. How much work is it to put this as variables in the ini 
file ? Everybody (like me ...) is lazy and once the problem is fixed for 
somebody it is up to next person to discover it again ;-)

No it is not MAX_ERROR. MAX_ERROR is the maximum allowed error between actual 
and commanded position. Once MAX_ERROR is exceeded EMC goes into estop 
because something is wrong.
