       - Part of feeds and speeds, HSM Works will auto fill many of the boxes, however due to the limited power and rigidity of the machine, stepdowns should be reduced based on the reference material and "multiple passes" should be used to reduce cutter load
       - "Material to leave" can be adjusted to create roughing passes if desired. Many operations such as adaptive clearing will automatically leave stock as it is assumed to be roughing operations.
     - Linking
       - Linking moves dictate how the cutter enters and exits the workpiece and can be altered to prevent the cutter from running into the stock while it attempts to start or finish a cut cleanly.
+  - Simulating
+    - Any toolpath generated can be previewed using the simulate function built into HSM Works. the Job or single operation can be selected before selecting "simulate" from the Solidworks command bar.
+    - Simulating code is a great way to see unwanted movements the tool may make or seeing if the tool is undercutting into important areas of the stock or crashing into the workpiece.
+    - Within simulation "stock" can be triggered on and off to see material removal in real time.
   - Posting
     - Post the code by selecting Post Process and selecting Carbide 3D (grbl) as the post configuration. The program name or number should be numbers only, and is typically notated 00001 (not necessary for carbide but good practice for larger machines) make sure to select the desired output folder as by default Solidworks buries the G-code

+  - Next while still under "Jog" position the machine can set part zero in three ways
+    - The less accurate way is to position the tool at part zero established in HSM Works by jogging the machine to the part zero location and pressing zero
+    - An edge finder can be used at the minimum RPM to find the part X and Y zero. The cutting tool can then be replaced in the spindle and re-zeroed using the automatic tool length touch off. Z zero can be established by sliding a paper of known thickness or a thin metal shim along the top of the part and slowly jogging the spindle down until slight resistance is felt on the shim from the tool tip. X and Y axles must then be adjusted by the radius of the edge finder, and Z Zero must be offset by the shim thickness
+    - The fastest way to establish part zero is by using the paper or shim on all three axis and offsetting X and Y by the radius of the tool plus shim thickness, and the Z axis by shim thickness.

 ====Choosing tools====
 Many tools are optimized for different materials, and although a 2 flute endmill can do most operations, it is not always ideal. Single and duel high helix endmills are available for plastics, woods, and composits, with carbide endmills and burs available for abrasive materials such as glass fiber reinforced materials such as circuit boards.

+====File Types====
+G-Code files will be posted with the file extension .nc whereas Carbide Create will post files with the file extension .egc. G-code files can be opened directly into a text editor if necessary to preview or edit the desired code. .egc is a propriety package for G-Code used by Carbide for some god forsaken reason, in order to preview the G-code directly it is first necessary to upload the file to Carbide motion before copying and pasting the code into a preferred text editor.

-=====Ultimaker 3 Quick Review=====
+=====Carbide 3D 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.
+  * Safety Glasses must be worn when machine is running
-  * Keep hands clear of printer during operation. Pause print before clearing or adjusting print.
+  * The acrylic shield must be in place and lowered before starting a job
- ====Safe Operating Procedures Review====
+  * The spindle must be completely stopped before adjusting or removing work piece
-  - Launch Cura version 4 (blue icon)
+  * After milling is completed, the work piece will have developed sharp burrs which must be removed with a hand file or sandpaper
-  - From connected printers, select IW-Ultimaker3
+====Safe Operating Procedures Review====
-  - Select File -> Open Files -> Open desired project (.STL file type)
+  - Design part using Solidworks or other CAD platform
-  - Using task bar on the left hand side, position model as desired
+  - Using HSM Works or Carbide Create generate tool paths
-  - From print settings, select slice height, infill percentage, and support
+    - Each different tool needs to be a separate job as only one tool can be loaded into the Carbide at a time
-  - Support can be generated using ether nozzle, typically nozzle one holds build material with nozzle two printing with dissolvable support material.
+    - Use 2D and 3D clearing and pocketing to remove the bulk of the material while using "stock to leave" to allow for a finishing pass
-  - Setting can be fined tuned using the "Custom" option from print settings
+    - Simulate the toolpaths to verify that the tool will not crash and is cutting in the desired location
-  - Within custom settings, nozzle and build plate temps can be adjusted (build plate temps should be based off of build material)
+  - Using the 17 and 11 mm wrenches loosen the collet nut to change out the tool or collet itself if switching shank diameter
-  - Save the file from Cura on a thumb drive
+  - Home the machine and zero the tool using Carbide Motion under the "jog" heading using paper or a shim. DO NOT FORGET TO ADD OFFSET OF TOOL RADIUS AND SHIM THCINESS
-  - Connect thumb drive to printer -> select desired file -> select print\\
+  - Upload the G-Code into Carbide Motion under "load"
-Note: Adjusting settings may lead to more (OR LESS) successful prints. Contact Workshop Wizard responsible for Ultimaker if print fails or knowledge of advanced settings is desired.
+  - Start program
 ====Post Processing====
-  * If support was constructed from ABS carefully break away with pliers
+  * Use a file to debur the part
-  * If support was constructed from PVA soak part in warm water for several hours to dissolve support structure
 ====Maintenance====
-  * Bed should be cleaned with IPA between prints
+  * Tools should be wiped clear of chips or coolant using an acid brush
-  * Print heads and silicone head protector should be cleaned as needed
+  * The router should be vacuumed out after every operation and at the completion of each job
-  * Filament should be dried before use if printer has been idle for several weeks
+  * Once a month the router should be moved and chips cleared from underneath machine body
-  * Bed leveling should be completed every time print cores are swapped
+  * Twice a year the router should be partially disassembled, cleaned, and re-oiled
-  * Print cores should be swapped  or purged after clog or to change print line width. Used print heads should be kept for spare parts
