## Setup

The build plate should be a 6mm thick (XXX check number)
aluminium plate on top of the printers' bed. The printers'
heatbed and glass should be removed.
Make sure there is very good ventilation.
* Perhaps add a gcode header/footer to the file.
* Copy the new `.gcode` file to SD card. Such as:
```bash
sudo mount -o uid=1000 /dev/sdc1 /mnt
mkdir /mnt/awesome/
cp awesome.gcode /mnt/awesome/
sync
sync
sync
sudo umount /mnt
sleep 5 # make sure the SD card has time to write before removing
```
* PUT ON PROTECTIVE EYE WEAR!
* Power off LASER.
* Disable LASER by removing key.
* Power off printer.
* Insert SD card into printer.
* XXX Tape transparency and paper together? XXX
* Place the transparency on top of THREE blank sheets of paper.
Position the transparency in landscape mode, unless portrait mode is needed.
Bottom left of transparency should be in front left corner on
printer.
* Secure the transparency/paper sandwich to the aluminium plate and bed
with three large paperclips.
* Slowly move toolhead to position where you want the bottom
left corner of the stencil to begin (e.g. X=0, Y=0 of the stencil). It is
probably best to have a margin of 50mm around the edges (XXX number).
Make sure the LASER will be past the clips holding the transparency in place.
* Power on printer.
* Make sure the Z height of LASER toolhead is good with jig.
Jig should be 40mm tall (XXX check number). It is presumed the LASER
has good focus at the toolhead jig height.
* If Z height needs adjustment, in printer LCD, go to Z movement
and move to the correct height. (XXX menu sequence).
* BE SURE TO PUT ON PROTECTIVE EYE WEAR!
* Turn key on LASER to enable.
* Power on the LASER via the power switch.
* If fan on the LASER PCB doesn't start, press `RESET` button on PCB.
* NOTE, LASER WILL TURN ON IN NEXT STEP!
* In printer LCD, go to print from SD card, and print the gcode file
generated above.
* Time to cut depends greatly on board complexity, but in general
it's less than 30 minutes.
* Power off LASER.
* Disable LASER by removing key.
* Power off printer.
* Remove paper clips.
* Remove stencil.
* Compare stencil to PCB.
