GRBL Uno firmware

A collection of firmware for your Uno, included in the archive are:

GRBL 0.9J - the official release. We still recommend this as a stable release for a basic CNC machine used with GRBL controller or CNC.JS

GRBL 1.1H - the official release. Some updated features (most notable improvements are in the laser department, so for your lasers machines, this is the way to go) will work with GRBL controller but CNC.JS will give you access to the full feature set of GRBL 1.1H

GRBL 1.1H_XY homing only. Same feature set as the official 1.1H release, but when you have a laser machine without an Z axis you might want to use this as it will not try to home a Z axis. (also our preference on normal 3 axis machines, we home X and Y and get the Z in position through probing rather than homing)
