Overview
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]

Using Grbl Controller 3.0
Preparing
- Power up Arduino and shield
- With motor off, manually position milling bit over origin (0,0) on the work piece. The origin is the intersection of X and Y on your CAD drawing.
- Start Grbl Controller
- Select COM port and open
Adjusting
- Choose appropriate step size (start with 1)
- Press the Z down button, the milling bit should move down towards the work piece 1 mm. The Z jog speed can be adjusted in menu Tools -> Options
- Repeat until the the bit is almost touching
- Turn on motor
- Press Grbl Controller's Reset button to zero the Arduino Grbl code
Sending G-code
- Choose Send GCode radio button
- Open desired file, usually .nc
- Press Begin. If for some reason there is a long, slow traverse, the controller may time out. Increase timeout value in Tools -> Options
Finish
- Turn off motor when milling is complete
Emergency
- Press the Reset, Stop or Close button on Grbl Controller - the steppers should stop within a second or two. If not, power off your shield
