Laser Config

The Laser version of the grbl firmware needs to be installed.

Once the board is flashed, enable Laser mode in firmware $32=1
Create a new Lightburn Device called 'Laser'
In Device Settings -> Set S-Value Max = 1000

Laser Test Prints and Calibration

Pen Plotter Config

Best to store master key and backups on an encrypted removable drive. I formatted a USB drive for this purpose.

Mount the encrypted USB drive and link it in to the default .gnupg directory (this will create a new keyring on your encrypted drive) ln -s /Volumes/NONAME .gnupg

Internet Scale Services Checklist

A checklist for designing and developing internet scale services, inspired by James Hamilton's 2007 paper "On Desgining and Deploying Internet-Scale Services."

http://mvdirona.com/jrh/talksandpapers/jamesrh_lisa.pdf

Basic tenets

Does the design expect failures to happen regularly and handle them gracefully?
Have we kept things as simple as possible?

	# # # Klipper Adaptive Purging - ZeroG Logo # # #

	# Based on the original found here: https://github.com/kyleisah/Klipper-Adaptive-Meshing-Purging/tree/main/Configuration
	# This macro will parse information from objects in your gcode to define a min and max area, creating a nearby purge with Voron flair!
	# For successful purging, you may need to configure:
	#
	# [extruder]
	# max_extrude_cross_section: 5

	# General Process
	Pre-heat Bed/Nozzle
	G28 Home
	Determine Z Probe Offset using paper shim method
	- M851 Z 0.0 Reset Z Probe Offset to Zero
	- G28 Home Again
	- Disable Software End Stops - M211 S0
	- Raise bed until paper just scratches the nozzle
	- Record that number as z-probe offset
	Set Z Probe Offset in Firmware
