Important: Always remove the platform before taking the material tray out of the printer. Failure to do so can result in material dripping down into or onto the printer causing failed builds and damaged equipment.

Process the calibration .stl file:
To check, modify, or fine-tune the printer’s parallelism and home position, the Home Position Calibration Cubes.stl file is printed. The printer must be powered on for the duration of the parallelism calibration, and the home position calibration.
Notice: Parallelism is achieved when the platform and material tray are aligned with each other. Home position is the lowest point of the build platform along the Z-axis, it is the start position of the build platform for printing.
1. Download the Home Position Calibration Cubes.stl file to the computer where the Envision One RP software is installed.
Notice: Home Position Calibration Cubes.stl is a file made of nine blocks, each block is five millimeters high. This file is located on the USB drive that is shipped with every printer, and in the Desktop Health Knowledge Base.
2. Open the Envision One RP software and select a buildstyle. See the Envision One RP® User Guide.
3. Import the .stl file into the Envision One RP software.
4. Print the Home Position Calibration Cubes.stl file, see Start Print Job Einstein Pro XL for details.
5. Once the print has been completed, check if there are nine cubes on the platform.
6. If any of the calibration cubes are missing, press the Manual Debris Removal icon and remove any cured particles that settled to the bottom of the material tray. Remove the cured material and discard.
Important: Wear protective gloves for working with uncured printed cubes and measuring them.
7. Gently remove the calibration cubes from the build platform using the scraper from the Starter Kit.
8. Clean the calibration cubes.
9. Place the calibration cubes on a clean paper towel-lined surface. Air dry in ambient room temperature/humidity for 10 min.
10. Take a close look at each printed calibration cube. The calibration cubes are labeled with numbers 1 through 9.
Measure the calibration cubes:
11. Each calibration cube corresponds to a specific area of the material tray:
Measure the height of each calibration cube and write down the location of the calibration cube and its measurement.
- If all the calibration cubes are within +/- 100 microns, then the printer is paralleled, and no further actions need to be taken at this time.
- If all the calibration cubes are within 4.85 and 5.0 mm, then the printer’s home position is correct, and no further actions need to be taken.
12. If the home position is correct and the printer is not paralleled, contact Customer Support.
If the printer is paralleled and the home position is not correct, skip to Home Position Calibration Einstein Pro XL.
