Settings, Units & Grid
Display units, grid spacing, snap tolerances, and nudge distances.
The Units & Grid tab controls how Beam Bench presents distances and how the canvas snaps your interactions.
Open it from Edit → Settings or Ctrl+,.
Fields
Display Unit
Buttons: mm / inches.
Controls the unit used everywhere distances appear: rulers, Shape Properties, Move panel, layer settings, the Step input.
Internally Beam Bench always works in millimeters; this setting only affects display.
Default: mm.
Speed Time Unit
Buttons: minutes / seconds.
Controls whether layer speeds are shown as mm/min or mm/s. GRBL controllers expect mm/min in G-code regardless; this is purely a display preference.
Default: see active machine profile. Most diode users prefer mm/s. Most CO2 users prefer mm/min.
Grid spacing (mm)
Number, min 0.1.
The major grid line spacing on the canvas, in millimeters.
Default: 10 mm.
When to change: set to a multiple of your common material thickness, or to match a jig you regularly use.
Object snap distance (px)
Number, 1–20.
How close to another object the cursor needs to be (in screen pixels) for the snap-to-object indicator to engage.
Default: 8.
Smaller values mean snapping only engages when very close, useful in dense designs. Larger values make snapping more aggressive.
Click tolerance (px)
Number, 1–20.
The screen-pixel radius around the cursor that counts as "you clicked on this object" when selecting.
Default: 5.
Increase for high-DPI displays or precise mice; decrease if you keep accidentally selecting nearby objects.
Nudge (mm)
Number, min 0.
The distance an arrow-key press moves the selection.
Default: 1 mm.
Fine nudge (mm)
Number, min 0.
The distance a Shift+arrow press moves the selection.
Default: 0.1 mm.
Coarse nudge (mm)
Number, min 0.
The distance a Ctrl+arrow press moves the selection.
Default: 10 mm.
