3D Printers

Recharge 3D printer desiccant pack

Remove the white rectangular plastic desiccant pack from the "free filament" tote box by the 3D printing cabinet.
Inspect the desiccant beads through the front window.
Use the legend by the window to gauge if the beads are wet.
If the beads are wet, plug the desiccant pack into a wall outlet. *Set a timer* and check every two hours. The unit will heat up to drive out the moisture, which will bead up on the inside of the unit before evaporating. Once the condensation is gone and the beads are a happy color again, unplug the unit.
Return the dried desiccant pack to the filament box and ensure the lid is closed.

Grab the cleaning kit. Located on the shelf in the 3d printer cabinet.
Use the Z Axis cleaning device in the kit. If a replacement is needed: https://www.printables.com/model/229145-z-axis-screw-cleaning-device
- Drip some Isopropyl Alcohol on a paper towel.
- Wrap the paper towel around the threaded rod.
- Clip the Z Axis cleaning device around the paper towel and threaded rod.
- Move the gantry up and down using the Z Axis Move option in the settings menu.
- Be careful, the Prusa printers do not stop automatically at the top of travel, so approach the top with caution.
Apply a dime sized amount of Lithium Grease to a paper towel and wipe up and down the Z Axis threaded rod.
Move the gantry all the way up and all the way down using the Z Axis Move option (Go to settings in the menu, then move axis, z axis).
Repeat the last two steps if the grooves of the threaded rod are not covered.
Wipe off any excess grease.
Turn off the printer.
Clean the round linear rails of the X/Y/Z axis with a paper towel and alcohol.
Apply a small amount of 3 in 1 oil to the rails and move the guides across the oil.
Wipe any excess oil off.
Inspect the belts for tension, when picked like a guitar string, they should lightly 'twang'. If they are loose or very tight, file a maintenance report.
Return cleaning kit to tool tray.
