  1. 1. Machine Maintenance and Troubleshooting Vicky Somma @TGAW vicky@tgaw.com This presentation available at https://www.slideshare.net/VickyTGAW/machine- maintenance-and-troubleshooting
  2. 2. Monthly Machine Maintenance - Smooth Rods Wipe down with a green scrub pad, clean cloth of paper towel. Taz6 and MakerBot - Do not lubricate or use cleaners. These rods are self-lubricated. For machines that do need attention PTFA 3-in-1 Oil
  3. 3. Monthly Machine Maintenance - Z-Axis Lead Screw Use a Lithium Based Grease (like Lucas White Lithium Grease NLGI #2) Apply to the threaded rods (popsicle stick helps) Move up and down the Z axis to distribute Wipe excess
  4. 4. Monthly Machine Maintenance - PEI Bed Clean with Isopropyl Alcohol 10:1 IPA to water with a clean cloth. Fine grit sandpaper (2000-2500 grit) can also be used
  5. 5. Monthly Machine Maintenance - PEI Bed New sheets available at: https://www.lulzbot.com/store/parts/lulzbot- taz-pei-sheet Learn More: https://www.youtube.com/watch?v=PH_L0xvZ Brs https://ohai.lulzbot.com/project/mini-replacing- pei/maintenance-repairs/
  6. 6. Monthly Machine Maintenance - Hobbed Bolt Sometimes plastic gets caught in the hobbed bolt in the extruder. You can clean it out by with a toothpick or pick. Make sure to rotate to get all the teeth. Learn More: https://www.youtube.com/watch?v=- hDi2X2JHmU Photo Credit: itworks3d.com
  7. 7. Monthly Machine Maintenance - Hot End Remove any melted plastic with tweezers (easier when nozzle is heated)
  8. 8. Monthly Machine Maintenance - Bed Leveling Washers Taz6-Specific Wipe with Isopropyl Alcohol or a clean dry cloth.
  9. 9. Monthly Machine Maintenance - Nozzle Wiping Pads Taz6-specific Using pliers you can pull it out and flip it. When boths sides are dirty, replace it. New wiping pads can be bought at LulzBot https://www.lulzbot.com/store/parts/lulzbot- wiper-replacement-kit-5pk
  10. 10. Monthly Machine Maintenance - Cooling Fans Clean off dust with Canned Air.
  11. 11. Machine Maintenance - Control Box Clean dust with Canned Air.
  12. 12. Monthly Maintenance - Check Belt Tension ● Dull twang if you pluck it ● Strong with a little give Sign of a loose belt-- circles print as ovals, layer shifting. Reference: https://forum.lulzbot.com/viewtopic.php?t =2661 Photo Credit: Simplify3D
  13. 13. Quarterly Machine Maintenance Check and if needed tighten screws on: ● Frame ● Stepper Motors ● Gear on Extruder ● Taz 6 - Hose Clamps are Tight
  14. 14. Machine Maintenance - Learn More LulzBot Taz6 https://www.lulzbot.com/maintaining-your-3d-printer http://download.lulzbot.com/TAZ/6.03/documentation/guide/PDFs_for_web/TAZ_6 _QSG_OPERATION_WEB.pdf MakerBot Replicator2 https://support.makerbot.com/learn/makerbot-replicator-2/printer- maintenance/maintaining-your-makerbot-replicator-2_13422 https://www.youtube.com/watch?v=lLF-mms5l7w
  15. 15. Troubleshooting - Clogs Extrusion is erratic. Can produce a spongy, weak print.
  16. 16. Troubleshooting - Clogs ● Manually push filament through ● With the nozzle heated, try to clear clog with a guitar string, acupuncture needle, or other small wire. ● Cold or “Atomic” pull. ○ Heat up the nozzle to normal temperature for the material ○ Turn off heat and let it drop to 90 degrees (for PLA) ○ Manually pull the filament out. Learn more about Cold Pulls: https://www.youtube.com/watch?v=g8uvh6kvr54
  17. 17. Troubleshooting - Clogs Preventing Clogs: ● Use good, quality filament (less chance of contaminants) ● Keep work area dust free ● Use a filament filter if needed (aka run the filament through a sponge) ● Don’t cook the filament in the nozzle-- don’t exceed the recommended temperatures and don’t let it just sit in the nozzle heated for long periods of time. ● Particular filled filaments (like Wood) should use nozzles 0.5mm or greater.
  18. 18. Troubleshooting - Bed Leveling and Start Up Heights
  19. 19. Troubleshooting - Bed Leveling and Start Up Heights Printing Too Close: ● Waves/Ripples ● Distortion or Loss of Details ● No Filament Coming Through at All ● When print stops, release of excess filament from built up pressure.
  20. 20. Troubleshooting - Bed Leveling and Start Up Heights
  21. 21. Troubleshooting - Bed Leveling and Start Up Heights Printing Too Far: ● Print Not Sticking ● Filament Line Rounded Not Flat ● Curling ● Can See Gaps Between Lines of Filament
  22. 22. Troubleshooting - Bed Leveling and Start Up Heights When Bed is unlevel, you’ll see differences within the same print. For example, one side may print fine, but the other side is showing signs of being too close.
  23. 23. Troubleshooting - Ghosting Vibrations on the machine can cause “echos” of details. Lower the vibrations of the machine: ● Make sure the machine is on a sturdy surface ● Make sure the machine frame is rigid (add braces or shock absorbers) ● Slow down the print to decrease vibrations.
  24. 24. Troubleshooting - Ghosting Learn More about Ghosting: https://www.youtube.com/watch?v=KaFp6Eqk0QI
  25. 25. Troubleshooting - Stringing ● Increase Retraction Distance ● Increase Retraction Speed ● Increase Cooling ○ Raising fan speed ○ Lowering temperature ○ Slowing down print to give layers more time to cool ○ Printing more than one (so it takes longer for each layer)
  26. 26. Troubleshooting - Stringing
  27. 27. Troubleshooting - Blobs and Zits Little blobs and zits on the outside of the print. ● Changing retraction and coasting settings ● Control where the “seam” is. ○ Random (pictured) ○ Fastest ○ User Defined ● Can also be caused by pauses in USB printing.
  28. 28. Troubleshooting - Blobs and Zits
  29. 29. Troubleshooting - Puckering Or Gaps in Top Layer Can happen with too few Top Layers over too low of Infill. ● Increase Infill % ● Increase Top Layers ● Increase Overlap between Infill and Perimeters
  30. 30. Troubleshooting - Puckering Or Gaps in Top Layer
  31. 31. Troubleshooting - Over and Under Extruding The printer is extruding more or less plastic than the software expected. Photo Credits - Simplify3D
  32. 32. Troubleshooting - Over and Under Extruding Try Adjusting “Line Width” settings in Cura. Other possibilities: ● Clog ● Bad Temperature ● Filament Diameter variances
  33. 33. Troubleshooting - Temperatures and Cooling Overheating can cause small, fine details to warp or be distorted. ● Lower temperatures ● Allow more cooling by slowing down layers ○ Set a Minimum Layer Time ○ Hack - print more than one item
  34. 34. Troubleshooting - Temperatures and Cooling
  35. 35. Troubleshooting - Temperatures and Cooling Under-heating can cause layer separation and bonding issues ● Raise the temperature ● Lower layer height Photo Credit: Simplify3D
