 ===== 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~~ **Focus laser to workpiece**: use the `move` tab in Lightburn with the plastic focusing puck OR use macros from the `console` tab to jog to the right height for common material thicknesses
+. ~~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~~ **Align design to workpiece**: make sure everything fits as expected in x/y axes by using Lightburn's frame button
+. ~~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 using a material test from the box on the top left lid of trogdor, cutting a new [material test pattern](https://docs.lightburnsoftware.com/1.7/Reference/MaterialTest), or referencing one from the [[../laser_material_library|laser material library]]

+. ~~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

+===== 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.
