 **Changing tools:**
-  - Turn the router off and using an acid brush remove metal shavings and any dust from the tool head
+  - Turn the router off and using an acid brush remove metal shavings and any dust from the tool and collect
-  - Using the 17 mm box wrench on the collet nut and the 12 mm open ended wrench on the spindle shaft flats loosen the collet and tool.
+  - Using the large open wrench on the spindle shaft flats and the spanner on the collet nut, loosen the collet and tool.
-  - Unscrewing the nut all the way allows the collet and tool to be removed from the spindle and changed out with a different tool of the same shank or with a different sized collet.
+  - Unscrewing the nut all the way allows the collet and tool to be removed from the spindle and changed out with a different tool of the same shank diameter or with a different sized collet.
   - Separating the collet from the collet nut can be done by pushing on the back end of the collet so that it becomes angled within the retaining collet nut and then can be pulled out.
   - Before reinstalling the new collet and tool, wipe down the tool shank as well as the collet and spindle tapper.
 **Homing and Zeroing the machine:**
-  - With the tool installed, make sure the bed is empty and the cover is closed before turning on the machine
+  - With the tool installed, make sure the bed is empty and the doors are closed before turning on the machine. The switch on the front of the machine should turn it on, however there are two different interlocks, one on the back of the machine which controls master power, and one on the hand unit which need a key before the machine will move.
-  - Launch Carbide Motion on the Carbide computer
+  - Launch ShopBot 3 from the laser cutter computer
-  - Under "Jog" select "Home Machine" and allow machine to home itself
+  - Select the X,Y table button from the red position window to send the machine to its home position
-  - Select "measure tool" and the machine will use the automatic tool length measuring tool to zero out the tool
+  - With the tool in the spindle, attach the grouping clamp to the tool shank or the spindle, and place the aluminum electrode on top of stock you wish to cut. Jog the tool to be above the electrode. Check that as the tool and electrode come in contact that output one lights up. Select the Z button from the same position window and the machine will automatically zero out the tool height then retract to 1/2" above the surface.
-  - Next while still under "Jog" position the machine can set part zero in three ways
+  - Next select the yellow keypad to move the spindle to find part zero broad movements can be made using the arrows, fine adjustment can be made by pressing the "Fixed" button and entering a jog distance per click.
-    - 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 by jogging using the virtual keypad. Offset the axis by the radius of the edge finder, and switch the console to advanced mode. Under the zero drop down select X or Y zero to set part zero. The cutting tool can then be replaced in the spindle and re-zeroed using the automatic tool length touch off.
-    - 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
+    - An alternative but fastest way to establish part zero is by using a piece of paper or shim and slowly jogging the axis towards the part until slight resistance is felt on the paper or shim used. The part zero can then be set after offsetting X and Y by the radius of the tool plus shim thickness, and the Z axis by 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.
 **Starting Job:**
-  - Load the desired G-code using the "Load" page
+  - Load the desired G-code using the File drop down and selecting "load new file"
-  - Zero out the machine to match part zero
+  - Make sure drawing zero matches machine part zero
+  - If cutting aluminum or cooling is desired, insert the blue hose from the air regulator in fume hood #3 into the clear tubing zip-tied to the spindle. Turn on fume hood air valve (regulator should be at 40 psi).

 ====Machine Limitations====
   * Each tool change should be accompanied by a new job within HSM Works
-  * Tool shank diameter is limited to 7 mm
+  * Tool shank diameter is limited to 13 mm
-  * Max stepdown is limited to .01" in metal and .04" in wood
+  * Max stepdown is limited to .05" in metal and .1" in wood
-  * Work area is limited to 8" x 8" x 4" x,y,z
+  * Work area is limited to 24" x 18" x 3.5" x,y,z
 ====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.
+G-Code files will be posted with the file extension .nc. G-code files can be opened directly into a text editor if necessary to preview or edit the desired code or opened within HSM-Works to send to a machine.
+====Test Part====
+Training will focus the machine set up and use, not directly on the CAM and its accompanying software HSM Works. Before training, please take a look at and try your hand at creating the CAM for this [[https://drive.google.com/drive/folders/1tIQK6wZ0pye2SwnreKSnFAT9z5EiAgyl?usp=sharing|| test part]]. The software you write will be used to demonstrate you competence on the machine. Feel free to reach out at any time to the Workshop Wizard running the training course if you are having trouble creating the part G-code. Use the .step file to create the CAM, reference CAM is stored in the .SLDPRT file under the HSM workspace.

 ====Safety Concerns====
   * Safety Glasses must be worn when machine is running
-  * The acrylic shield must be in place and lowered before starting a job
+  * The acrylic doors must be closed before starting a job
   * The spindle must be completely stopped before adjusting or removing work piece
   * After milling is completed, the work piece will have developed sharp burrs which must be removed with a hand file or sandpaper
 ====Safe Operating Procedures Review====

     - 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
     - Simulate the toolpaths to verify that the tool will not crash and is cutting in the desired location

-  - 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
+  - Home the machine and zero the tool using Shopbot 3, set part zero using the yellow keypad and slowly jogging the tool or edge finder to the part. DO NOT FORGET TO ADD OFFSET OF TOOL RADIUS AND SHIM THCINESS

+  - Upload the G-Code into Shopbot 3 under File-> Load
   - Start program
