官方故障排除步骤
[Cause of error] No safety clearance at diameter. No safety clearance was programmed at the diameter of the grinding wheel. When the dresser approaches the grinding wheel, it moves toward the wheel edge up to a safety clearance. To ensure that the diamond does not touch the wheel at this position, the safety clearance must be at least as large as half the dresser width. [Error correction] Define a safety clearance at the diameter.
