Usage Notes

• Power switch is in right rear
• X button below front panel knob is hard reset
  • If pressed, will need to reconnect to printer in OctoPrint

• Flexible, removable bed plate
• Remove by lifting at front
• Return to printer by aligning rear edge first
• Clean bed only with isopropyl alcohol (small spray bottle) and lint-free wipe
• No extra adhesives allowed: no glue sticks, no tape, no hair spray, no ABS slurry
• Do not clean bed with acetone - you will damage the coating
• Do not use metal tools on the bed, only soft plastic, fingernails, credit card, etc.

• Load filament via menus
• Cut filament tip at 45 degree angle before loading

• Recommend Hatchbox or Prusa filament
• Currently only allowing PLA and PETG on this printer
• Consult shop stewards for different filament needs

OctoPrint

• Can send directly to OctoPrint from Slicer on 3D printing area PC
  • Pick the Physical Printer option
• OctoPrint will run the ArcWelder plugin to optimize the uploade gcode
  • Print the version of gcode with .aw added to filename to get optimized version
  • Print the version without .aw to get original slicer gcode output

• At start of print, printer may beep and warn about needing firmware upgrade - ignore this
• Recommended to use brass brush tool to clean pre-heated nozzle before printing

• Monitor the start of your print - at least the first few layers

• Unload the filament when done

• Infill over 40% is generally wasted

• If you customize slicer settings, they will not save on 3D printing PC
  • To save your own custom settings, save to a .3MF file [note: not seeing how to do this]
• When loading a .3MF file, if you drag it into slicer, it may override printer settings
  • Instead use the Add tools to add the .3MF file and only take the object model(s)

General and Special Safety Considerations:

This is not an exhaustive list!

• Read, understand and follow all warning labels, instructions and safety manuals.
• Take the class.
• Extruders and build plate are HOT: 100 C to 270 C.
