CR-30 Skew Compensation Calibration Cube 20mm

Used to measure XY offset

1. Look up and record current X-axis,Y-axis Steps/mm
2. Print test block
3. Measure test block and record value.
4. current Steps/mm x 20mm (Original image size) / (Print test block record value) = new Steps/mm
5. Enter new value from as new steps/mm value
6. Repeat this at least 3 times.
7. Store values to before powering off.

用於校正XY軸偏移量

1. 查看印表機 X軸、Y軸 原本步數 (CR-30原廠設定皆為80)
2. 列印測試塊
3. 測量測試塊的X、Y方塊數值
4. 原本步數 x 原圖尺寸(mm) / 印出來測量尺寸 = 最後需要設定的步數
5. 輸入新的步數置印表機
6. 重複三次，直至測試結果接近20mm
7. 保存設定值並載入設定值。
