3-Grbl Controller Software; Installation - Abra CNC ENGRAVER 01 Manual

3-GRBL CONTROLLER SOFTWARE

In this step, we establish connection to Candle CNC to test our motors and load our milling
files. Using this software, we can also issue G-code commands to modify the machine's
EEPROM firmware.
To properly install and operate the CNC Machine kit, Arduino software and libraries
must be installed. Some computers may also require the CH340 serial drivers to be
installed. Please note, that some laptops may not be able to support this CNC
Machine. We recommend using a desktop computer with USB 2.0 port if possible.

3.1-INSTALLATION

Several different software options are offered for running the CNC machine. The ABRA
Kit uses Candle. Different users prefer different versions. Usually the code is open-
sourced and is updated frequently. The firmware is also available for download. Become
familiar with the versions and decide which is best for you.
