Remixed for use with a 500mW Laser sourced from AliExpress. Initially, planned to pair it with CNC Shield V4. The following components were intended for integration: 3314197 and 3314168. A crucial requirement is utilizing the Y-Base from the original setup. Attention to detail is essential here. It's imperative to modify GRBL settings for seamless operation with the shield. Unfortunately, the circuit layout presents an issue that necessitates adjustments. To rectify this situation, navigate to grbl-master>cpu_map>cpu_map_atmega328p.h and make the necessary changes. Specifically, switch the ports associated with DIRECTION and PULSE for each axis in this file. Additionally, it's worth noting that spindle on/off control via PWM is accessible through the Z+ Endstop due to a modification made in GRBL Versions regarding PWM port switching.
