- Laser enable is Fan0 on the physical board now, virtual Fan 1 FAN1_PIN (P2.03). Enable Laser with M106 P1. Turn off laser completly with M107 P1. You can set this in your post processor.
- Laser PWM/TTL is +5v pulled from the center Neopixel data pin (P1.24) now mapped to FAN_PIN in Marlin. (I hope this doesnt confuse anyone) set laser power with M106 Sxxx (0-255)

Marlin 2.0 takes this popular RepRap firmware to the next level by adding support for much faster 32-bit and ARM-based boards while improving support for 8-bit AVR boards. Read about Marlin's decision to use a "Hardware Abstraction Layer" below.
Download earlier versions of Marlin on the Releases page.

Marlin is published under the GPL license because we believe in open development. The GPL comes with both rights and obligations. Whether you use Marlin firmware as the driver for your open or closed-source product, you must keep Marlin open, and you must provide your compatible Marlin source code to end users upon request. The most straightforward way to comply with the Marlin license is to make a fork of Marlin on Github, perform your modifications, and direct users to your modified fork.
While we can't prevent the use of this code in products (3D printers, CNC, etc.) that are closed source or crippled by a patent, we would prefer that you choose another firmware or, better yet, make your own.
