3. Scale The Scale function is used to resize an imported file This can be VERY important due to the fact that imported objects into Slic3r are always considered to have been designed in mm For example if you designed a button that s 1 inch in diameter and inch thick that button will be imported as 1 mm in diameter and Y mm thick That s a tiny button In order to resize the button to its original dimensions click on Scale and input 2540 Scale Enter the scale for the selected object 2540 OK Cancel If you designed the file in cm then the scaling would need to be entered as 1000 If you wish to simply double the size of a shape then highlight the file click on Scale and enter 200 Note that after using this function you may need to manually drag and separate shapes in case any are overlapping 29 4 05 7 Split PU e 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 Name Name Cop Scale Bat and Boo stl Bat and Boo stl 1 100 Bat and A 1 100 Two objects are listed after applying Split e The same file name is used for both objects since there s no way for Slic3r to know how to name the

8. Retain the silica packets which come with every roll of filament Store them with the opened rolls of filament in a dry room temperature storage area such as a cabinet or drawer Unraveling and subsequent uneven rewinding can lead to filament breakage the next time it is used in the printer Try to avoid unraveling by either securing the loose end of the filament through the small holes in the spool or by taping the loose end to the spool If you use tape be sure to cut off that part of the filament before loading into the printer since any adhesive stuck to the filament could cause clogging in the nozzle It s a good idea to check the filament diameter on any new spool of filament especially if you have purchased a different brand different color or different type Calipers can be purchased on Amazon or at Harbor Freight Tools Measure in several locations along the first few feet and then input an average diameter under the Filament Settings gt Filament screen in Slic3r 7 06 Checking the Frame Frequency H once a month M once a quarter L after every 50 or so prints Also check any time the printer has been moved Make sure the bolts which hold the frame together are all still tight If any can be moved by hand tighten them To check for proper alignment print a test square and verify that all four corners are right angles Here are two five minute test files for you to use one is a 3 inch square and the other is a 75 mm

Build Plate Surface Check Frequency check before every print Keep the build plate clean and free of wrinkles After every print make sure all remnants of filament are removed after the printer is at room temperature Make sure the tape that is adhered to the plate is wrinkle free Sometimes wrinkled tape can be pulled up and then squeegeed back down again using a plastic scraper If the tape on the plate is torn or if wrinkles cannot be removed replace the tape Remember that paper tape is recommended for printing PLA and plastic tape is recommended for printing ABS If the build plate has any kind of grease or oil it can prevent the filament from sticking during a print If this is the case it can be wiped down with rubbing alcohol or other degreaser However please use the following steps o Turn off the power to the KNP3D o Make absolutely certain the printer is at room temperature o Make sure the degreasing agent is thoroughly wiped off the plate Q Do not leave the degreasing agent near the printer Store it elsewhere before turning the printer back on again 7 02 Build Plate Leveling Tramming Frequency H once a week M once a month L after every 15 20 prints Also check any time the printer has been moved Refer back to Section 2 04 for instructions on leveling tramming If you find that adjustments are not being needed then you can decrease the frequency for checking 7 03 Extruder Cleaning Frequency
