The tape measure is delivered with xTool P2 riser base, designed to help you determine the replacement level of the baseplate when you use xTool P2 with the riser base.
Use the front side to measure the material's thickness for accurate baseplate placement.
Use the back to measure the material's perimeter to set the baseplate and roller level accordingly.
To process material with a thickness of 130 mm, refer to the Riser base level (baseplate right side up) markings. For example, marking 2a indicates that you can place the baseplate at level 2a.
To process a long material with a thickness of 20 mm, place the baseplate upside down and refer to the Riser base level (baseplate upside down) markings. The marking 1a indicates that you can place the baseplate at level 1a.
To process a cylindrical material of perimeter 180 mm in roller mode, read the markings in the Riser base level and Roller level series. The riser base level is 1 and the roller level is B, indicating that you need to place the baseplate at level 3 and set the adjustable roller to level B.
You need to use the chuck to process a sphere with a perimeter of 180 mm, you can place the baseplate at level 1a and then place the rotary attachment and material for processing.
