Software Details

The CNC xPRO is designed to run the opensource gcode interpreter GRBL, opensource programming environment Arduino, or anything you can write in AVR studio.  The xPRO comes pre-flashed with GRBL so all you need to do is wire up your motors! 

From the computer side we have found that ChiliPeppr - Grbl Panel - Universal-G-Code-Sender and GRBL Controller 3.0 work extremely well (and are free downloads). 

The software stack used at Spark is:

NOTE: "Please do not use the mass settings updater within GRBL 3.6.1, setting are not properly mapped for GRBL 0.9g"

Basic Setup

NOTE: Accessories such as the BlueTooth, etc. Can be purchased from Spark-Concepts.com
