  • Maintenance. A well treated 3D printer should give you years of trouble-free printing. Here are some suggestions on how to keep your pet 3D printer well maintained.

  1. Oil your X, Y, and Z rods.  I do this about once a month.  

  2. Periodically tighten nuts and bolts.  Again, monthly.

  3. Periodically test and tighten belt tension.  I check and adjust belt tension rarely – usually only after I see a printing problem develop.

  4. Periodically test your filament tension.  Too tight and you’re putting extra strain on the extruder motor.  Too loose and you’re not really getting the best extrusion possible.  As plastic filament actually has a slight variation in its diameter, this is something I monitor whenever I am printing.  It’s partially a way for me to fuss over my robot as it is happily printing away.  If I notice that the extrusion is suddenly too thin, a quick adjustment to the filament tension screw will fix this.  I’ve heard that adding a second nut to the filament tension screw prevents the screw from loosening slightly over time.

  5. Repair or replace.  Having a 3D printer means that if a part breaks or wears out you can actually replace it.  Just accept the fact you’re going to bend, pop, snap, crackle, or pop a part.  When that happens you’ll need to rig or hack a temporary solution while you print up a replacement part.  One benefit to a solid plastic replacement part to a component that’s assembled out of layered plastic and/or plywood is that there are no parts to loosen over time.

  6. Floss extruder gear.  Use something soft-ish like a toothpick to pop the plastic bits out of the gear’s teeth.

  7. Keep firmware updated.  firmware has come a long way and I’m pretty sure it to go even further.

  8. Keep software updated. Software is constantly under development.

  9. Replace warped build platforms or build surfaces.  A flat even build surface will ensure nice flat builds without having to worry about the extruder head crashing into the platform.

  10. Keep your plastic in a cool, dry place.  As mentioned above, the filament’s diameter can very slightly.

  11. Check wire connections on any moving axes.  The cable clips attaching motors, endstops, and various other bits to the XY stages can work themselves loose after time.  I check these whenever I see that a cable might be working itself loose.
