Grbl 1.1 Download
This release includes a critical bug fix (rare) and some other minor bug fixes, updates and new non-critical features.
[fix] A very rare bug would cause Grbl to crash in a very special and very rare set of circumstances. It would occur only when actively lowering feed/rapid overrides and the programmed move and settings aligned perfectly. Re-factored the problem code to eliminate the potential issue.
[new] A nonlinear spindle speed/PWM output option via a piecewise linear fit model. Enabled through config.h and solved by a Python script in /doc/script.
Firstly make a note of your GRBL machine settings. Download the GRBL version you want to flash onto the controller board from GitHub. It is the ZIP file you will need. Unzip it and remember where you put it. Download the Arduino IDE and install it (if you haven’t already got it). You will need the Windows App, not the online web. Last stable version: latest All versions: github.com/arkypita/LaserGRBL LaserGRBL is free and opensource, but it’s development require time and money. Aug 25, 2019 Primarily used to independently home both sides of a dual-motor gantry with a pair of limit switches (second shared with Z-axis limit pin). When the limit switches are setup correctly, Grbl will self-square the gantry (and stay square if $1=255 is programmed). Beware use at your own risk! Grbl is not responsible for any damage to any machines. The Arduino Uno runs the Mill One by using a tailored version of the GRBL v1.1g firmware. This firmware is set up for ⅛ microstepping and can be flashed onto your Arduino by using the Arduino IDE. Click this to download the firmware, then follow these steps.

[new] fit_nonlinear_spindle.py. A solver script that can be run on http://repl.it for free. No Python install necessary. All instructions are available in the script file comments.
[new] stream.py has been updated to include status reports feedback at 1 second interval. Autocad 2016 download 32 bit.

[new] The stream.py streaming script now has a check-mode option, where it will place Grbl in $C check mode automatically and then stream the g-code program. It's a very fast way to check if the g-code program has any errors.
[fix] stream.py bug fix with verbose mode disabled.
[fix] When in M3 constant laser power mode, a change from G0 to G1 would not set the laser on, if G1 was passed with a coincident target. Motion controller now checks for a coincident target situation and will force a spindle sync when detected.
[fix] Restrict M3 forced updates when there is a motion block with a coincident target. Force syncing of the spindle state can lead to some pauses during a job that has coincident targets. That’s not particularly desirable. This ensures M4 dynamic mode is not effected by this force-sync.
[fix] The build info options of “two switches on an axis” and “homing init lock” shared the same letter ‘L’. The former is now ’T’.
[fix] When M7 and M8 are both enabled, $G report would show M78, rather than M7 M8. This only effects systems that enable M7 mist coolant in config.h. Not the default build.
[fix] When trying to enable laser mode with $32=1 and VARIABLE_SPINDLE is disabled, the error code shown was improperly stating it was a homing failure. Added an new error code specifically for the laser mode being disabled without VARIABLE_SPINDLE.
[fix] The debug variable was not initialized if the debug option was enabled in config.h
[fix] Updated error_codes CSV file to the same format as the others.
[update] Added PocketNC FR4 defaults. Needs some additional work though to be compatible.

GRBL 1.1 Features
Overrides and Toggles
Platform version only. Easily control the real time feed and speed overrides by enabling the Overrides widget in the Window menu.Jog Mode
With older versions of GRBL UGS is pretty reliable when it comes to jogging, but there are limitations. With GRBL 1.1 this is no longer the case when using the new JOG MODE syntax. This first-class jog mode guarantees the GCODE state will be unaltered, and also allows you to stop a jog while it is in progress. UGS uses this new syntax automatically when it detects a version of GRBL which supports it. During a jog use the STOP action to stop an in-progress jog:Pin State Reporting
Platform version only. New flags have been added to the controller state window to indicate when various external switches are enabled.Message resolution GRBL removed most help and error messages to make room for new features on the micro controller, they are now provided as data files in the grbl source code. UGS uses these data files to resolve all error codes and setting strings.
Platform
The next generation of UGS. Fully modular front end powered by the same robustlibrary created for the Classic GUI.
Fully modular GUI, reconfigure windows to suite your needs.
Built in gcode editor with line highlighter.
Customizable keybindings.
Zoom to selection with command and drag.
Right click in the visualizer to jog to a specific XY location.
Classic
The classic GUI has everything you need to get started.
3D visualizer.
Job complete dialog.
Machine control.
