  • Page 22: Navigating Slicer Software

    Slicer software converts 3D models from their inherent format (typically .STL) into G-code that can be inter- preted by the Model G0923. This conversion is mostly automated, but users have the ability to manipulate the model and change print settings in order to customize the print and maximize quality.

    Pausing Print During printing, press control dial to open print menu (see Figure 30). Typically, the Model G0923 prints from a .GCODE file stored on an SD card. Print settings such as print speed, fan speed, and nozzle temperature can be changed during printing, and the operation can be paused for an extended period of time and resumed.
