Grbl Controller 3.6.1 for Mac, Windows and Linux - by Zapmaker
Grbl Controller is a piece of software which is used to send GCode to CNC Machines, such as a ShapeOko. As of version 3.0, the software has been optimized to send GCode to a Grbl Arduino Shield, which is the standard and default controller type for the ShapeOko.
Grbl Controller is written to work on Windows, Mac, and Linux. It has been written as a superior replacement for the popular GCodeSender, and UniversalGCodeSender.
User Bobt was able to get it running on a Raspberry PI.[1] c.f. Running Grbl Controller on Raspberry Pi
Implements “Agressive preload” and Z-rate limiting options.[2]
Will trim too-long lines when sending.[3] Current version doesn't consider line-endings, so will overflow the buffer, change the Grbl Line Buffer Size in Tools | Options from 50 to 49 (48 on linefeed and carriage return systems such as Windows).[4]
