Use of SHOPBOT
-Always wear safety glasses when operating the ShopBot or observing the machine when it is in use.
-Never leave the machine when it is in operation.
-If you need a bathroom break, the machine can be paused by pressing the Space Bar on the control PC keyboard.
-Make sure the bed of the machine is clean before use. Inform us if it is not clean.
-Securely fasten your material to the bed of the machine. Consult us every time you are faced with a different, challenging or unusual work-holding scenario.
-Perform command “C3” Homing routine to establish the true machine home X-0 Y-0 (in the machine coordinates system)
-Jog X, Y to your personal Work Home coordinates, ie: the corner of your material & the X,Y origin of your drawing.
-Take a photo of the Control PC screen or take note of the machine coordinates system to your chosen Work Home position. Example: X - 105.499, Y - 145.376 (do not worry about Z yet). Work Home X Y coordinates are simply offset measurements from the true Home (X-0, Y-0) of the Machine.
-Zero work coordinates to X-0 Y-0
-Install tool in collet/tool holder + install tool/tool holder on spindel.
-Use command ”C2” & follow prompts on the PC screen (You will place the Z-0 plate directly under the tool on your material & place the Alligator Clip onto the collet nut on the tool holder) to set the Z-0 of your home position coordinates. You now have all 3 of your X, Y & Z work home coordinates loaded into the CNC system.
-Load part file, to choose the file you need to launch, you will see your “G-Code” which you generated in RhinoCam on the screen.
-Visually check again the machine bed to ensure all tools have been removed and that material is securely fastened to the bed.
-Start in ShopBot software, follow prompts.
-Start the spindle with the green button on the ShopBot remote.
-Monitor the machine closely until the machine stops. Laser Cutters and CNC Routers have a high risk of fire if left unattended.
-If you need to pause the machine, press the Spacebar on the PC Keyboard. The machine will pause, then follow the prompts to restart or end the process.
-Emergency stop buttons are located in 2 places: On your remote, next to the Control PC, and On the end of the Y - Axis gantry. The Emergency Stop buttons are large, round Red buttons which will completely shut-down the machine.
-Remove the tool-holder & tool from the spindle and store it in the tool-holder rack.
-Clean the machine and your work area completely after you have removed your material.
-Skeletons and scraps created during the process should be cut up & placed in the recycling cart.

Important commands
Set Z zero
Run command C2. Put the metal plate under the machine head and connect the aligator grip to the tool head. Run Enter. The machine will go down and adjust its Z zero. Done.
Set XY zero
Run command C3. The machine will move. Wait. Done.
Change a toolpath tool
Run command 72 (press CN and then 72). The machine will leave its tool on its tool holder and will go to look for the new tool. Once the new tool is load the machine will move to the Z tool distance area in the toolpath. Connect the aligator grip to the tool head. The machine will go down and save the tool length. Done.
