+. ~~checkbox~~ **Turn on computer**: if it isn't already
 . ~~checkbox~~ **Wait ~10s before opening Lightburn**: a background process needs to configure the laser first
 . ~~checkbox~~ **Open Lightburn, wait for homing cycle**: the machine will automatically "home" itself i.e. confirm the position of each axis by driving motors to reach endstop sensors

 ===== Prepare To Cut =====
-. ~~checkbox~~ **Prepare design in Lightburn**: import SVGs, clean up cutpaths, etc.
+. ~~checkbox~~ **Pick a coordinate system**: you probably want to use absolute coordinates. See [the official docs](https://docs.lightburnsoftware.com/1.7/Reference/CoordinatesOrigin/#)
+. ~~checkbox~~ **Cut selected graphics (or not)**: sometimes it's helpful to enable "cut selected graphics" in Lightburn, sometimes not. Best to double check if it's enabled before a surprise either way.
+. ~~checkbox~~ **Focus laser to workpiece**: use the `move` tab in Lightburn with the plastic focusing puck or macros from the `console` tab to jog to the right height for common material thicknesses
+. ~~checkbox~~ **Test power/speed**: Pick some starting values by cutting a [material test pattern](https://docs.lightburnsoftware.com/1.7/Reference/MaterialTest) or referencing one from the [[../laser_material_library|laser material library]]
+. ~~checkbox~~ **Align design to workpiece**: make sure everything fits as expected in x/y axes using Lightburn's frame button
+===== Cut =====
+. ~~checkbox~~ **Send it**: Run your job in Lightburn
+. ~~checkbox~~ **Don't go far!**: You need to keep an eye on the laser during the entire job. When lasers catch things on fire, they tend to do so quickly.
+===== Power Off =====
+. ~~checkbox~~ **Wait ~5 minutes**: Make sure the chiller has had time to cool down the tube, and the blower has fully evacuated any remaining fumes
+. ~~checkbox~~ **Turn off machine**: large switch, right side of cabinet
-TODO: confirm "cut selected graphics", coordinate system, etc.
+===== Troubleshooting =====
+- If Lightburn switches to the console tab and displays red error text in the console output, probably GRBL (the controller's firmware) has thrown an alarm. There is a macro called "Reset" on the console tab that will reset the alarm and re-home the machine.
