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.
