Free Zeta System is the system for recovering a print at a known height. Measure the value Z of the last printed layer, then:
  • Menu > Prepare > Move Axis > 10,1,0.1 > Z axis;
  • Get close until last layer is touched and take note of Z value.
  • Menu > Free Zeta System;
  • Insert Z value;
  • Select .gcode.
Wait for file to load. The operation, depending on the height, can take up to several minutes.
