 ====== Unimatic CNC Router ======
-  * Isel C142 controller
+===== System =====
-  * plugged into a laptop running LinuxCNC
+The CNC router is made up of multiple parts. \\
+{{:cnc_router_labeled_parts.png?400|}}
+  * CNC machine frame: made by unimatic - [[https://learn.lboro.ac.uk/ludata/cd/cad/cnc/unimatic.htm|Specs]]
+      * Movement: X 1000mm, Y 1200mm, Z 240mm [TODO: check dimensions]
+  * Spindle: water cooled, 3 phase, with a ER20 collet chuck
+  * Motion Controller: Isel C142 controller, for controlling the stepper motors of the machine
+  * Computer: Laptop Dell Latitude D600 (?), running LinuxCNC
+  * Chiller: DN CW-3000 - [[https://www.plexishop.it/pdf/CW-3000-hiendro.pdf?srsltid=AfmBOopCnQEHzMEm9eGbC0osFTS2MrBN-S3NLAzhaCIrc69DoYqA7KIQ|Manual]]

+===== How to use the CNC router =====
+=== Start up procedure ===
+{{:cnc_router_labeled_buttons.png?400|}} \\
+**1)** turn on the laptop
+   * open the lid and reach the power button, which is located on the back left corner of it's keyboard
+   * Note: make sure not to pull out the cables plugged into the laptop while turning it on
+       * The cables that are plugged into the laptop include: video cable for monitor, power cable, Serial port to RS485 converter for VFD, Parallel port for motion controller, USB keyboard and mouse
+   * Note: make sure the USB stick is not plugged in when booting (it will try to boot from it otherwise)
+   * Turn on the monitor above the router
+       * the display source should be "INPUT-2" displayed on the screen, press the "INPUT" button on the monitor if it says "INPUT-1"
+   * log into the laptop using username: ''hacklab'' password: ''hacklab''
+**2)** Pull out the estop (gently) on the motion controller \\
+**3)** Release the estop button on the machine by twisting it \\
+**4)** Log in by tapping your token on the tool controller \\
+**5)** Turn on chiller \\
+**6)** Push green button mounted next to VFD.
+  * Note: This will send power to the stepper motors
+  * Note: The-Z axis will drop a few centimetres.
+      * Unload any fragile tools first, if you are worried about them being damaged.
+      * The drop is due to the Z-axis electromechanical break disengaging a little before the stepper motors get power
+  * Note: Wait for the laptop to boot before pressing the green button
+       * The laptop sends out random signals out on its parallel port when it boots, and would make the CNC mill move around randomly, which is dangerous
+=== Shut down procedure ===
+  - Press the main estop next to the machine - this is done first, the rest can be done in any order
+  - Turn off the chiller
+  - Log out from the tool controller
+  - Turn off the laptop
+Note: the motion controller Estop does not need to be pressed
+=== Using the router ===
+Double click the 'Linux cnc' icon on the desktop
+TODO
+=== Recovering after emergency stop is pressed ===
+TODO
+=== How to use the manual touchoff pad ===
+There is a touchoff pad plugged into one of the inputs of the motion controller
+The spindle + tool are grounded, so the tool contacting the touchoff pad completes a circuit
+TODO (Gcode sequence)
+Estop: chiller, button, tool controller
+chiller estops when water temperature is above 60*C or water flow flow is stopped or water level is low
+===== Maintanence =====
+Dust extractor needs emptied periodically, follow instructions on the dust extractor

 The step blocks and clamps we have at the moment are 3D printed. Don't push the machine too hard while using these. If you want to mill thick metal at high speeds, you'll need a metal clamping set; the lab has discussed purchasing a set like [[https://www.arceurotrade.co.uk/Catalogue/Workholding/Clamping-Sets/24pc-Clamping-Set-8mm-M6-Thread|this one]] in the past and there should be no problem doing so if anyone needs them.
