This will disable everything, including the stepper drivers.

Dynamic Laser Power Scaling with Speed : If your machine has low accelerations, Grbl will automagically scale the laser power based on how fast Grbl is traveling, so you won’t have burnt corners when your CNC has to make a turn! Enabled by the M4 spindle CCW command when laser mode is enabled!.Switch between “laser” mode and “normal” mode via a $ setting. Spindle speed overrides also work with laser mode so you can tweak the laser power, if you need to during the job. When “laser” mode is disabled, Grbl will instead come to a stop to ensure a spindle comes up to speed properly. Laser Mode : The new “laser” mode will cause Grbl to move continuously through consecutive G1, G2, and G3 commands with spindle speed changes.Documentation is included on how this works and how it can be used to control your machine via a joystick or rotary dial with a low-latency, satisfying response. Jogging Mode : The new jogging commands are independent of the g-code parser, so that the parser state doesn’t get altered and cause a potential crash if not restored properly.Grbl executes overrides in realtime and within tens of milliseconds. Most hobby CNC’s try to mimic this behavior, but usually have large amounts of lag. This awesome new feature is common only on industrial machines, often used to optimize speeds and feeds while a job is running. Real-time Overrides : Alters the machine running state immediately with feed, rapid, spindle speed, spindle stop, and coolant toggle controls.This is due to the addition of two new spindle speed ‘$’ settings. IMPORTANT: Your EEPROM will be wiped and restored with new settings.(USA) aka Built on the wonderful Grbl v0.6 (2011) firmware written by Simen Svale Skogsrud (Norway).

Grbl includes full acceleration management with look ahead. Macro functions, variables, and most canned cycles are not supported, but we think GUIs can do a much better job at translating them into straight g-code anyhow. Arcs, circles and helical motion are fully supported, as well as, all other primary g-code commands. It accepts standards-compliant g-code and has been tested with the output of several CAM tools with no problems. It is able to maintain up to 30kHz of stable, jitter free control pulses. The controller is written in highly optimized C utilizing every clever feature of the AVR-chips to achieve precise timing and asynchronous operation. This version of Grbl runs on an Arduino with a 328p processor (Uno, Duemilanove, Nano, Micro, etc). The detail of GRBL V1.1 laser mode can be found from GRBL v1.Grbl is a no-compromise, high performance, low cost alternative to parallel-port-based motion control for CNC milling. So, everything is nice and smooth with the laser mode in GRBL. However, if it is used to control a laser, the staying leads to scorching, uneven cutting depth, or bumpy engraving marks! The laser mode prevents unnecessary stops whenever possible and adds a new dynamic laser power mode that automatically scales power based on the programmed speed along the path. In the spindle mode, every time a spindle state (such as M3, M4, or M5) or spindle speed (Sxxx) is altered, the controller temporarily stops the feed motion. This gives time to allow the spindle to speed up/down. The main difference between them is how the spindle/laser output is controlled with motions. So, what is the principle behind that makes them result differently? The planner moves the laser point to your defined coordination and tuning the PWM power of your laser diode in both laser and spindle modes. What is the difference between laser and spindle mode in GRBL? You need to correctly configure the GRBL settings when installing the firmware to your machines. Therefore, laser mode has been introduced in GRBL v0.9 or higher. The laser process has almost the same control loop, except for the tweak of laser power. The controller was primarily developed for CNC milling, controlling the spindle rpm, which is known as spindle mode.

GRBL is an open-source firmware that runs on an Arduino for converting g-code commands to the motion control of CNC machines.
