Each mode generates a specific G-code test pattern. Select one to configure and download.
Paired tick-mark rulers along X to detect steps/mm errors and backlash.
Paired tick-mark rulers along Y to detect steps/mm errors and backlash.
Both X and Y rulers drawn in one pass.
Rulers along all four sides — useful for checking squareness via diagonals.
L-shaped corner marks to verify the axes are perpendicular.
Depth-amplified X marks at the four corners to reveal surface height errors.
Same depth-amplified marks spread across an evenly-spaced grid.
Velocity ramp test to measure X-axis deflection across a range of accelerations.
Velocity ramp test to measure Y-axis deflection across a range of accelerations.
Dense G1 segments to stress-test firmware parsing and communication speed.
Unidirectional surfacing passes to flatten a spoil board or a workpiece.
Progressive feedrate test to measure deflection and find the maximum cutting speed.
