How to fix edger feed roll slipping on a USNR MyEdger
Feed roll slipping in the edger causes boards to stall or skew, reducing cut accuracy. Clean the rollers, check nip pressure, and inspect the drive for wear.
How to recover yield loss from an USNR MyEdger optimizer
Poor edger yield is usually caused by misaligned scanner inputs or outdated lumber value tables. Verify scanner calibration, update lumber prices, and compare optimizer solutions to manual measurements.
How to fix a trimmer saw not dropping on a USNR MyEdger Trimmer
A trimmer saw that fails to drop misses the optimizer cut solution and reduces board value. Check the saw pneumatic cylinder, solenoid valve, and optimizer output signal before replacing components.
