====General Procedure====
====General Procedure====
# Software
## The Mark II utilizes cloud-based print software Eiger. This means that the software can be accessed from any browser, but an account is required to do so. As such, prints will need to be started by management.
## After login, the main screen returns to library. From this page, you can view and modify previous prints for reprinting or import a new STL for printing.
## Once imported or selected, print material may be selected (Onyx in this case) reinforcement type may be selected and orientation may be edited in the pane on the right. Clicking a part face will orient that face to the build plate. Reinforcement and material settings may be edited with drop-down menus (these are generally best done in the internal view). Brims and support may be toggled on or off from the Part Settings drop-down menu. All these options are available from part view.
## From internal view, density (number of layers of carbon fiber) may be viewed and edited using the slider at the bottom of the page (Blue is carbon fiber, White is main material).
## Material costs and totals may be viewed in the upper left of the part screen. It's worth noting the dramatic change in cost with addition of Carbon Fiber inlay.
## All Mark II prints should be okay-ed with Justin Johnson (the shop supervisor) before being started. Once setup is completed and the printer is on, prints are sent to the printer via the "Print" option. Generally, select the option to start the print from the machine, rather than automatically.
# Printer Setup
## The printer may be turned on with a switch on the rear of the machine. The machine will boot up and may need to update, let it complete this process.
## Before starting the print, glue needs to be applied to the build plate. Simply lift the build plate off the mount and apply the glue stick (found in the Markforged drawer/box) to the area where the print is located in the software (be sure to account for extra width due to the brim), the back of the plate where the machine will purge (print excess material which has been sitting in the lines and exposed to air), and the corner where the purge tower is located in the image below. [[File:Mark II Build Plate.jpg|thumb|A Mark II build plate with purge tower and purge line.|none]]
## Place the place back on the mount. The Mark II is ready to print!
# Printer Shutdown
## Upon completion of the part, select clear bed on the touchscreen and remove the build plate from the mount. The purge line and tower should be easily removable by hand.
## For the part itself, take the putty knife found in the Markforged drawer/box and carefully remove the part. This may take quite a bit of force to accomplish. Make sure the blade of the putty knife and your hand will never come into contact if you slip (i.e.: brace the plate on the table and push the knife away from you along the plate). Work the knife along the perimeter of the part's attachment to the build plate and avoid prying with the knife when possible. [[File:Removing Parts from Mark II Build Plate.jpg|thumb|Removing parts from the Mark II build plate.|none]]
## After the part is removed, wash the plate with warm water only. When the plate is clean, dry it with a paper towel and place it back on the mounts.
## The plate is ceramic, avoid dropping it. The plate will absorb oil, it is normal to see fingerprints, etc. on the plate.
