-=====F270 Quick Review=====
-Tool Lead: Andrew Furst \\
-Contact: Andrewfurst@ucsb.edu
-====Safety Concerns====
-  * Both print heads and bed are heated during operation. Do not attempt to clean, remove, or adjust without allowing for adequate cool down time.
-  * Keep hands clear of printer during operation. Pause print before clearing or adjusting part.
- ====Safe Operating Procedures Review====
-    - On the F270 printers computer, launch GrabCad Print
-  - Select File -> New Project -> Add Models -> Import desired models
-  - Move models around on virtual build tray so that models on a used build tray do not overlap any previously printed spots
-  - the purge block and printed model should be placed close together to minimize print time
-  - Select "Print Settings" from the menu on the right hand side
-  - From menu, select desired slice height, and verify that the first layer material is set to support.
-  - Open and place build tray into F270, making sure that the tray is locked in place by pulling up on the front locking arm until arm is PARALLEL to build tray.
-  - Select print, and send the job to the F270 3D printer
-  - on the F270 touch screen, select your job, and then select print.
-====Post Processing====
-  * If support was constructed from dissoluble filament clean using the F270 Support Removal Apparatus which is filled with heated caustic chemicals. GLOVES, LAB COAT, AND FACE SHIELD MUST BE WORN
-  * Build tray should be scraped clean and free of any support or build material then placed in the USED F270 tray drawer if printable space is left. Any material protruding from the build tray will damage print heads during the next print.
-====Maintenance Schedule (see user maintenance page 80):====
-  * Clean oven chamber weekly
-  * Clean platen weekly
-  * Inspect, wipe, and clean tip wipe assemblies monthly
-  * Clean exterior of printer as needed
-  * Clean touchscreen as needed
