Our 3d printers are used heavily. There are certain '''weekly''' tasks that need to be done, as well as repairs. Repairs can be found on the main [[3d Printers]] page.

At least weekly, the 3d printers need to be oiled. Find the Silicone oil in the 3d printing area, invert the bottle to apply oil to:
The 3d printers need to be oiled when bars are dry. Use sewing machine oil (mineral oil) in the 3d printing area--do not use grease!
Apply oil to:


* cross beams supporting the head
* x, y axis beams supporting the head
* plate raise bar
* z axis bars
* attenuation bars (sides, under the lid)


Actuate the print head to spread the oil around.

=== Greasing ===


The z-axis lead screw is greased. This is done rarely, generally during overhauls. Wipe the lead screw clean with a rag to remove old grease and dirt.

Leveling is the process of making sure that the print beds are flat and leveled, and that print heads are the right space away from the plate at '''all points'''. There's a built in leveling tool, but that tool is for very 'gross' adjustments, like when you move or take apart the printer, or change the nozzle.

Apply a line of Magnalube grease to the lead screw.

Turn on the printer. Navigate to 'Maintenance' -> 'Advanced' -> 'Raise Print Bed'. Once raised, select 'Lower Print Bed' from the same menu.

Wipe off excess grease that builds up at the top and bottom of the lead screw.

⚫
Leveling is the process of making sure that the print beds are flat and leveled, and that print heads are the right space away from the plate at '''all points'''. Follow the directions provided by the printer screen to level the build plate with a Post-It note. Bed should be leveled like when you change the nozzle.
There's a file on each of the Ultimakers in a folder called 'UM-Tools' on most lab SD cards, called 'bedlevel_nozzel_0-4'. Print that, and a grid should be printed.


Visually, and with your finger, test (feel) where is thick and where is thin. During the print, adjust the screws on the '''bottom''' of the plate (for Ultimakers), until the lines from the print are even across the plate.
There's a file on each of the Ultimakers in a folder called 'UM-Tools' on most lab SD cards, called 'bedlevel_nozzel_0-4'. Print that, and a square zig-zag should be printed. You can use this to check your level and make on-the-fly adjustments if needed. Visually, and with your finger, test (feel) where is thick and where is thin. During the print, adjust the screws on the '''bottom''' of the plate (for Ultimakers), until the lines from the print are even across the plate.
