You can also try to change the setting value 191.
191 Default Smoothness
This setting may be set to ROUGH, MEDIUM, or FINISH and uses parameters 302, 303, 314, 749, and 750-754 and
G187 to set the smoothness and a maximum corner rounding factor. The default values are used when not overrid-
den by a G187 command.
