Webb[skew_correction]¶ Printer Skew Correction. It is possible to use software to correct printer skew across 3 planes, xy, xz, yz. This is done by printing a calibration model along a plane and measuring three lengths. Due to the nature of skew correction these lengths are set via gcode. See Skew Correction and Command Reference for details. WebbWith SIMPLEC, the pressure-correction under-relaxation factor is generally set to 1.0, which aids in convergence speed-up. In some problems, however, increasing the pressure …
