 +    - 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.

 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.  Many tools are optimized for different materials, and although a 2 flute endmill can do most operations, it is not always ideal.

 ====Safe Operating Procedures Review==== ====Safe Operating Procedures Review====
-  - Launch Cura version 4 (blue icon) +  - Design part using Solidworks or other CAD platform 
-  - From connected printers, select IW-Ultimaker3 +  - Using HSM Works or Carbide Create generate tool paths 
-  - Select File -> Open Files -> Open desired project (.STL file type) +    - Each different tool needs to be a separate job as only one tool can be loaded into the Carbide at a time 
-  - Using task bar on the left hand side, position model as desired +    - 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 
-  - From print settings, select slice height, infill percentage, and support +    - Simulate the toolpaths to verify that the tool will not crash and is cutting in the desired location 
-  - Support can be generated using ether nozzle, typically nozzle one holds build material with nozzle two printing with dissolvable support material. +  - Using the 17 and 11 mm wrenches loosen the collet nut to change out the tool or collet itself if switching shank diameter 
-  - Setting can be fined tuned using the "Custom" option from print settings +  - 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 
-  - Within custom settings, nozzle and build plate temps can be adjusted (build plate temps should be based off of build material) +  - Upload the G-Code into Carbide Motion under "load" 
-  - Save the file from Cura on a thumb drive +  - Start program
-  - Connect thumb drive to printer -> select desired file -> select print\\ +
-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. +
  
 ====Post Processing==== ====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==== ====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+
