USNR LASAR scanner & headrig

Headrig saw vibration causes wavy sawn surfaces and increases saw kerf waste. Check arbor bearing condition, saw tension, and collar flatness before increasing feed speed.

Carriage positioning error results in off-dimension lumber and reduced yield. Check the setworks encoder, drive chain, and carriage rail alignment before running a dimension cut test.

Scanner calibration drift causes the optimizer to misread log dimensions and reduce lumber value recovery. Run the calibration procedure with a certified target and compare optimizer outputs to measured dimensions.
