Work Offsets & Zeroing

At a glance

  • Color-coded G54–G59 badge tracks the live active WCS; click to switch with live offset previews
  • Zero X/Y/Z split buttons: zero the axis, Set to a value, or Increment — inputs take expressions like 1/16
  • Zeroing moves the rendered toolpath to where it will physically cut
  • Display follows G20/G21 live — the whole DRO flips units the instant the program does

The DRO shows work coordinates alongside machine coordinates, with a color-coded badge for the live active WCS (G54–G59). Click the badge to switch — each row previews its stored offsets — or let a program's G5x word drive it.

Zeroing

The Zero X/Y/Z buttons are split buttons: the icon zeros the axis in the active WCS; the caret offers Set to value… and Increment…, both accepting expressions (5/2, 1/16) in the live display unit. Zeroing updates the controller's work offset, and the rendered toolpath moves to where it will physically cut — what you see is where it lands.

Units

Display follows the active G20/G21 modal live: run a metric program and the DRO, feeds, and jog steps flip to millimeters the moment it takes effect, and back on G20. Geometry never moves — only the displayed numbers change.
