===== Power On =====


1. ~~checkbox~~ **Turn on machine**: large switch, right side of cabinet
1. ~~checkbox~~ **Confirm blower is running**: ducting will obviously be moving air
1. ~~checkbox~~ **Turn on computer**: if it isn't already
1. ~~checkbox~~ **Wait ~10s before opening Lightburn**: a background process needs to configure the laser first
1. ~~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 =====

1. ~~checkbox~~ **Pick a coordinate system**: you probably want to use absolute coordinates. See [the official docs](https://docs.lightburnsoftware.com/1.7/Reference/CoordinatesOrigin/#)
1. ~~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.
1. ~~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
1. ~~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]]
1. ~~checkbox~~ **Align design to workpiece**: make sure everything fits as expected in x/y axes using Lightburn's frame button

===== Cut =====

1. ~~checkbox~~ **Send it**: Run your job in Lightburn
1. ~~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 =====

1. ~~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
1. ~~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.
