 The space has a 3 axis CNC machine based on the High-Z S-720 from [CNC-STEP](https://www.cnc-step.com/high-z-s-720-cnc-router-720-x-420-x-110-mm-trapezium-screws/). To use the machine either 1T, Elvis, Teus or Sander should be present. 
 
 ## Safety
-The machine has two E-stops (emergency stops). One is located on the x-axis gantry and another one on the controller electronics box. When pressed they cut the voltage to the spindle, motors and controller board. ``TODO: FACT CHECK``.

 ## Getting started guide
 
+### Energizing the machine
+- Plug in the machine
+- Make sure both estops are not activated
+- Press the green energize button on the electronics box

+
+### Launch gcode sender 
+
+Turn on the CNC laptop or CNC computer and launch **gsender**. Other options will work too but we found this option to be the easiest one to use. 
+
+<div style="width: 100px;">

+
+After launching gsender you should see the homescreen with a greyed-out button that says disconnected.

+<div style="width: 100p%;">

+![gsender home](./images/cnc-machine/getting%20started/1-connect.png)
+</div>
+
+Go to the top left, make sure the firmware is set to ``grblHAL`` and not ``grbl``, go to recognized devices and choose the USB option.
+
+After this the greyed-out button should become green and say connected. You are now ready to start moving the machine.

+
+## Homing and moving the machine
+- Always start by pressing the <button style="color: white; background: #356FA7; border: 1px solid grey; border-radius: 1px; padding: 6px 4px;">🏠 Home</button>
+ button in the top right
+- After that you can move the axises but keep in min that there are only endstops at the home position (0,0,0)
+
+
+
+The machine will not stop itself from destroying itself so be careful!
+
+## Designing CNC routines
+
+Out of scope I think? Me (1T) and Elvis can help you get started probably though. We have done it a couple times now in Fusion 360 free edition.
