4.9.4.5 Code 129: Arc Accuracy
When the SMX control operates at high feedrates it may create small part machining errors
as it goes around sharp corners. This exists on all CNC’s and is commonly called a “following
error.” The control is factory preset to allow a maximum following error of 0.001 inch. The
feedrate will automatically be adjusted around sharp corners so as to not violate this limit.
This code only applies to arcs that are programmed and ones that are created in the tool
path to generate the shape you want. This code will not make a difference on mill moves.
You may adjust the maximum following error to a value as small as .0001 inch. However, the
smaller the value, the slower the feedrate around corners.
To input a new Following Error use the following procedure:
Follow the instructions on the screen and input the Following Error value (from .0001 to
.0100) and press INC SET.
