Overview

Grbl Controller 3.4 (previous version was 3.3.x and added a visualizer and other features) for Mac, Windows and Linux - by Zapmaker

Version 3.0 was a near-complete rewrite of the code and added native Mac support, including special installer for 32 bit Intel OSX 10.5.

An important feature is the ability to cycle the COM port via Reset, Stop or Close buttons. This provides auto-zeroing of the controller to simplify start of milling.

User Bobt was able to get it running on a Raspberry PI.[1]

Implements “Agressive preload” and Z-rate limiting options.[2]

Will trim too-long lines when sending.[3]

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
