1: PART IS NOT STICKING TO BED
a. Open Repetier Host to view the GCODE
b. Generally higher temperatures make for better bed adhesion
c. For ABS, Nylon, PC, etc, make sure to use the purple Elmer’s glue stick on the PET film.
d. Adding brims to the first layer of your printer (at zero distance) [especially for PC and nylon]
e. The better the printer is calibrated, the better the first layer is, the better the part sticks
2: CANNOT GET PART OFF THE GLASS
a. Remove glass from printer and let cool
b. You can use the following tools to help remove the part: Rubber mallet, flimsy spatula, putty knife, razor blade
3: PART IS WARPING
a. Too much heat, reduce nozzle and bed temp
b. Slower speeds
c. Refer to part 1 (Part is not sticking to bed)
4: PART IS CRACKING
a. Printing with ABS for large parts may tend to crack
b. Increase nozzle/bed temp in 5 degree increments, do not exceed 15 degrees above default
c. Caused by long prints, try decreasing the print time (increase speeds, decrease infill, increase layer height)
d. Increasing wall thickness to 2-3 may help
e. Use PLA or PET for larger/longer prints
5: MATERIAL IS NOT EXTRUDING (clicking noise, mouse bite, clogged nozzle)
a. Heat nozzle and remove material and check for mouse bite
b. Heat nozzle to 260C (or 315C for advanced materials), insert material and try to manually feed the material through the nozzle
c. Close extruder assembly and extrude 500-1000mm of material to flush/purge the nozzle
d. May consider removing and cleaning the nozzle
e. Use the z-adjust to make sure the nozzle is not too close to the bed
6: PRINTING SMALL PARTS
a. Use small layer heights (0.100-0.200mm)
b. Use slower speeds (10-30mm/s)
c. Use lower temps (5-10 degrees below default)
7: PRINTING LARGE PARTS
a. Use large layer heights(0.200-0.400mm)
b. Use faster speeds (30-75mm/s)
c. Use less infill (10-30%)
8: VIKI
a. Check connectors behind the Viki display
b. Ensure SD card is not above or below the slot
9: FAN IS NOT WORKING
a. Preheat PLA through the VIKI as this will turn on the FAN
b. Contact tech support if the fan does not turn on after engaging Preheat PLA
c. The fan only turns on for certain materials, refer to material settings for specific information
10: MOTORS ARE NOT WORKING
a. X axis, test with Xhome
b. Y axis, test with Yhome
c. Extruder, test with manual extruder control in Viki, will only function when printer is preheated
d. If all the motors do not move after performing auto home, you may need to replace fuses, refer to maintenance section of manual for wiring diagram
11: Z-AXIS LOCKED/ BED WILL NOT MOVE UP OR DOWN
a. Please contact tech support for direct assistance Tag: 3D Printers User Guide
