Job is rotated or mirrored

The result on the material does not match the canvas orientation. Mirrored, flipped, or rotated 90°.

You see

You designed something on the canvas. The machine ran. The result on the material is the wrong way around: mirrored left-right, flipped top-bottom, or rotated 90°.

What is happening

Almost always a workspace origin direction mismatch. The machine and Beam Bench disagree about which corner is workspace origin (Bottom Left vs Top Left), so output that points "up" on the canvas ends up pointing "down" (or vice versa) on the material.

Fix

If the design is mirrored top-to-bottom

Your machine profile's Origin does not match the actual machine. Open Device Settings → MachineOrigin. If your machine homes to the front-left of the bed, set Origin to Bottom Left. If it homes to the back-left, set to Top Left.

Save, reconnect, re-run.

If the design is rotated 90°

The X / Y axes are swapped. Possible causes:

  • Machine wired with motors swapped (rare after initial setup).
  • A rotary attachment is still active and the project is set up for a flat bed.

Verify the machine moves the expected direction when you click Right in the Move panel, it should move the head right, not up.

If only one specific layer is rotated

The objects in that layer have a per-object rotation set. Select them, check the rotation field in the Properties Toolbar, reset to 0 if unexpected.

If the design is mirrored left-to-right

Less common, usually motor wiring is reversed. Check the $3 setting (direction port invert mask) in GRBL via the Console.

Verify it worked

  • Frame walks the design's perimeter on the material in the expected direction.
  • A test burn confirms orientation.
