Cohesion3D LaserBoard
The Cohesion3D LaserBoard is a direct replacement for the M2 Nano and can be installed in under 20 minutes to provide an immediate performance upgrade as well as the ability to utilize LightBurn Software.
It runs Smoothie Firmware as shipped but can also run GRBL. Smoothie is the only firmware which calculates the PWM value based on acceleration every single step, resulting in the cleanest possible cut and even power around corners.
