CNC Milling

Our CNC mill is controlled by Grbl. When your CAM software has an output option for Grbl, use it. Otherwise, Grbl understands LinuxCNC/MachineKit G-Code and you can use a setting for that. If you have neither option, you can use a generic setting. LinuxCNC/MachineKit try to obey standard G-Code.

User Interface

The mill uses bCNC for DRO, manual jogging, and g-code sender.

Manual Jogging

Setting excessively high jog size can cause commands to be buffered and the machine to crash! Do NOT set jog step higher than 0.5 mm or 0.02 inches!

Keyboard jogging works only when the Canvas or any non-editable field is selected. If you are in the text editor or in the command line, press <Esc> to select the Canvas.

Key Command
Right arrow Pan +X
Left Arrow Pan -X
Up Arrow Pan +Y
Down Arrow Pan -Y
PgUp Pan +Z
PgDn Pan -Z
+ or = Increase step by one unit (=current decade)
- or _ Decrease step by one unit (=current decade)
1 Set as step the step1 (default 0.1) value from the configuration
2 Set as step the step2 (default 1) value from the configuration
3 Set as step the step3 (default 10) value from the configuration
* Multiply step by x10
/ Divide step by /10

There is also a pendant controller that can be used to send jog commands as well as G-code start and pause. To use the pendant, select the pendant icon from the toolbar on the Control tab (look for the hand icon).

Feeds and Speeds

  • Aluminum
    • 1/4" two-flute endmill, 1400 RPM, 4 IPM works well. Feed rate is limited by machine vibration.
