Process Calibration .stl File

1. Download the Home Position Calibration Cubes.stl file to the computer where the Live Build DLP software is installed. See Primary Supplies to download the .stl file.
2. Open the Live Build DLP software and select a buildstyle. See Upload Buildstyle File for details.
3. Import the .stl file into the Live Build DLP software.
4. Print the Home Position Calibration Cubes.stl.
5. Once the print is completed, check if there are nine cubes on the platform.
6. If any of the cubes are missing, tap the Manual Debris Removal icon and remove any cured particles that settled to the bottom of the material tray, see Manual Debris Removal.

Post-Process

1. Gently remove the calibration blocks from the build platform using the scraper that came in the Starter kit.
2. Clean and dry the printed models.
   Important: Do not cure the printed cubes.
3. Take a close look at each printed block. There is a small number printed on each cube.
   

   

Measure

Measure the height of Cube 1 and write down the value in the Cube 1 section:

Continue writing the value for each cube until all cubes are measured.

• If all the blocks are within +/- 100 microns, then the printer is paralleled, and no further action is required.
• If all the blocks are within 4.85 and 5.05 mm,  then the printer’s home position is correct, and no further action is required.

If the home position is correct and the printer is not paralleled, submit a tech support ticket via Customer Support at https://etec.desktopmetal.com/support/.

If the printer is paralleled and the home position is not correct, skip to the next section.

Adjust Home Position

Important: Do not adjust Home Position until the printer is parallel.

1. Remove the platform from the printer and place it aside on a clean work surface.
2. On the home screen, navigate to Settings > Move & Calibration > Home Calibration.
   

   

3. Set the value of a step by tapping the – and + icons of the Step Value. This is the increment used for the Motion Distance. The Step Value increments can be set to 0.01, 0.10, 1.00, and 10.00.
4. Set the motion distance of the platform by tapping the – and + icons of Motion Distance. This is the total distance the platform moves.
5. Reference the values from section Measure to determine the new home position. The adjustment should be made based on the average height of the calibration blocks.
   1. If the average height measurement is below 4.85 mm, move the platform up by pressing Move the required number of steps.
   2. If the average height measurement is above 5.05 mm move the platform down by pressing Move the required number of steps.
6. Press Save.
