Zeroing the Workpiece

Work zero (work offset origin) is the point your G-code uses as X0 Y0 Z0 for the job. You set it on the workpiece or fixture so the toolpath aligns with your stock.

What you’ll do​

  • Choose a reference on the workpiece (corner, center, etc.)
  • Set that position as work zero using manual zeroing, a touch plate, edge finder, or another method
  • Use Go to Zero to rapid back to that point when needed

When to use it​

Set work zero:

  • Before every new job
  • After changing the workpiece or fixture
  • After a tool change, if you re-zero Z (e.g. with a touch plate)

Set Zero (quick zero)​

Set Zero sets the current machine position as work zero (X0 Y0 Z0, or only the axes you choose).

  1. Jog the tool to your reference (e.g. front-left corner of the part, top of stock).
  2. Click Set Zero (and choose which axes, if the UI offers it).
  3. That position is now work zero. The DRO shows 0 (or 0,0,0) at that point.

Use this for manual zeroing. For touch plates or edge finders, use the dedicated zeroing workflows. See Zeroing methods.

Go to Zero​

Go to Zero rapids the tool to the work zero position (X0 Y0 Z0). Use it to return to your origin after jogging away, or to start a run from a known position. Ensure Z is safe (high enough) before rapiding; jog Z up first if needed.

warning

Verify clearance before Go to Zero. The machine rapids to X0 Y0 Z0. If Z0 is on top of the part, retract Z first.

Why it matters​

Incorrect work zero causes wrong placement of the toolpath: scrap parts, tool damage, or collisions. Always confirm your reference and re-check after changing anything (workpiece, fixture, vise).
