Maintaining Your 3D Printer
3.8 Bed Leveling Washers and Calibration
Cube
Keep the washers and calibration cube mounted on the Y axis plate clean
and dust free by wiping them periodically with Isopropyl Alcohol (IPA), or
a clean dry cloth. If the bed leveling washers are not clean during the bed
calibration process the print surface or tool head may be damaged. If the
calibration cube is not clean during the oset or backlash probing, you can
get inaccurate results and possibly damage your tool head. Never attempt
to clean the bed leveling washers or calibration cube during the probing
sequence as it may lead to personal injury.
3.9 Cooling Fans
Every 2-4 weeks carefully clean your hot end cooling fan by powering o
the 3D printer and unplugging the tool head from the extruder harness.
Gently blow any dust away with short bursts from a can of compressed air.
3.10 Control Box
If dust is evident on the control box vents, unplug the printer and use
short bursts of compressed air to blow out any dust. Once a quarter it is
recommended to completely open the electronics cover, and blow away any
debris on the board using short bursts from a can of compressed air.
