Keyboard

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

Keys

<Right> pan +X
<Left> pan -X
<Up> pan +Y
<Down> 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

Mouse

Use the Gantry button or the [g] shortcut (gantry) or <Control> + <Shift> + <Left Mouse Button> on the canvas, to move gantry to the hit location.Be careful!

Command line

Enter directly a G0 X## Y## Z## in the command line to move to the desired location See even more at Command Line

External Keypad

You can use an external keypad (USB or wireless) for jogging. This is a cheap and easy method for moving the gantry.

<4> pan +X
<6> pan -X
<2> pan +Y
<8> pan -Y
<9> pan +Z
<3> pan -Z
<+> Increase step by one unit (=current decade)
<-> Decrease step by one unit (=current decade)
<*> Multiply step by x10
</> Divide step by /10
<1> Homing

If the orientation of the pan keys doesn't fit your setup you can enter a 'swap' parameter in the [Control] section of your .${HOME}/.bCNC file.
The default is '0'. '1' will rotate the axis clockwise, '-1' counter clockwise.

Note: the current implementation of a jogging feature in bCNC has not incorporated the new jogging capability from Grbl 1.1, which allows the user to cancel the movement in real time. For this reason, be careful when sending multiple jogging commands as you will not be able to cancel commands that are already in the buffer and therefore may crash the machine or hit the limit switches.

DRO

Also you might want to modify coordinates directly without jogging. You can type them into DRO and hit enter. Also you can use math formulas in there:
