  • Page 23: More About Slic3R

    Here’s a list of the key things to check when using Slic3r:  Do not automatically upgrade to the latest version of Slic3r without seeing an announcement by KNK Forum. It’s important that any changes made in Slic3r not impact the KNP3D in USA at the User unexpected ways.

  • Page 24: Slic3R Tabs

    These settings will normally remain the same unless you change to a different type of filament, such as switching from PLA to ABS.  Printer Settings are related to the KNP3D itself, such as the bed size, firmware type, and number of extruders. 4.03 Understanding Profiles ...

  • Page 25: Changing And Saving Settings

     A profile can contain settings for just one tab or for more than one tab:  For example, one could have a profile of settings pertaining to ABS which was set up under Filament Settings. One might also set up Print Settings more suited for ABS than for PLA. These two profiles could be saved under separate names - ABS Print and ABS Filament.
  • Page 26 is a great way to not only learn the function of that setting, but also to better understand the 3D printing process itself. Also take note that Appendix B and the Slic3r User Manual cover these settings in more detail. ...

  • Page 27: Plater

    As a safeguard, you should also save all of your settings by going to File > Export Config Bundle, and selecting a folder on your computer in which to save the configuration. Give it a new name, such as “My KNP3D Profiles”. ...

  • Page 28: Delete And Delete All

     You are not limited to adding and printing only one file at a time. For example, in the screen shot below, two different STL files have been imported using the Add button. Both files will be printed and the two files together can be saved as a single STL file by clicking on the Export STL button on the right side.

  • Page 29: Rotate

    4.05.5 Rotate There are three icons used for rotating:  ° The first two rotate buttons will rotate a highlighted object in 45 degree increments, counterclockwise and clockwise as indicated by the icons.  The Rotate button allows you to input the exact degree of rotation desired. ...

  • Page 30: Split

    4.05.7 Split  Split is used to separate individual objects within an imported file. For example, let’s suppose the bat and “Boo” were created together in a 3D design program and imported as a single STL file. Then let’s also suppose you only want to print the bat. By highlighting the file and clicking on Split, the two objects are now separate: Two objects are listed after applying Split.

  • Page 31: Settings

     Another application for the Cut function is when your object is too large for the build plate or shaped where the bottom will not have sufficient contact area with the build plate to insure a good print. The Cut function can be used to dissect the file into two or more sections for printing. Then, after the individual parts are printed, they can be glued together.

  • Page 32: More About Printing

    One use for preheating is to save a little time. While you are finalizing your file in Slic3r, you can go ahead and begin preheating the KNP3D. It will be closer to target temperature once you are ready to load your file from the SD card.

  • Page 33: Pausing The Print

    There may be a reason to pause a print, such as the filament running out or discovering a small thread of filament caught in the object. The KNP3D can easily have printing paused and resumed. There are three kinds of pause modes available and are presented in this section.

  • Page 34: Pause At Zpos

    The following window will open indicating the current Z axis location. Change that setting to the location where you want the KNP3D to pause the print. Naturally, this will need to be a higher value than what’s shown in this window because a lower location has already been passed.

  • Page 35: Cold Pause

    5.03.3 Cold Pause  Cold Pause is used to pause the printing process for an extended period of time. The KNP3D will remain powered on, however all heaters, stepper motors, and LED lights will be shut down.  To access the Cold Pause option during a print, press the left arrow to bring up the following menu.

  • Page 36: Changing The Extrusion Temperature During A Print

    There are several reasons why you will need to unload the filament at some point:  Changing to a new or different spool of filament  Not planning to use your KNP3D for an extended period of time (remove filament and store in a dry location)  Needing to unclog the extruder.

  • Page 37: Changing Filament During A Print

    (5) When the extruder reaches the set temperature, the KNP3D will play a little tune, prompting you to load or unload the filament. The feeder inside the extruder will begin to push the filament back out. The display will show: (6) If you are trying to clear a clog and get the filament flowing again, then immediately go back to Loading Filament on the control panel and proceed with those steps.
