SLEC (segmented linear error correction)
Use the SLEC tab to setup and enter SLEC data. SLEC applies linear error
correction coefficients to segments of each axis to compensate for encoder and
machine travel variations. Use a standard to measure each axis and compare the
measured (observed) values to the nominal (standard) values to generate correc-
tion coefficients. Correction coefficients are generated for each segment that
deviates from the standard value and provide linear compensation for that seg-
ment.
Enter the zero point first for each axis. This does not mean that each axis must
start a zero: negative values can be entered. For example, you can enter the zero
point for the X axis and then enter standard and observed values for -2.
Correction for the final point on each axes continues in constant manner. Thus
a correction applied to the final point continues for all points past the final
point. Likewise, if no correction is applied to the final point, no correction
applies to points beyond it.
