Adjust Parallelism

1. Download the .stl file to the computer where the Live Build DLP software is installed.
2. Open the Live Build DLP software and select a buildstyle. See Upload Buildstyle File.
3. Import the Home Position Calibration Cubes.stl file into the Live Build DLP software.
   Note: Home Position Calibration Cubes.stl file is made of nine blocks, and each block is five millimeters high.
4. Print the Home Position Calibration Cubes.stl.
5. Once the print has been 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.
7. Gently remove the calibration blocks from the build platform using the scraper that came in the starter kit.
8. Clean and dry the printed models. Do not cure the printed cubes.
9. Take a close look at each printed block. There is a small number printed on each cube.
10. Measure the height of each cube and write down the values.
    1. If all the blocks are within +/- 100 microns, the printer is paralleled, and no further actions need to be taken at this time.
    2. If all the blocks are within 4.90 and 5.10 mm (for the disposable tray: within 4.80 and 4.950 mm), the printer’s home position is correct, and no further actions need to be taken.
11. If the home position is correct and the printer is not paralleled, move on to Step 12. If the printer is paralleled and the home position is not correct, skip to the Automatic Home position calibration subsection.
    

    

12. Using the 1.5 mm Allen wrench, unlock all four locking screws by turning them two full rotations to the left.
13. Reference your values in Step 10 to determine which side needs adjustment. Find the two extremes. One corner is most likely the highest and the opposite is the lowest. We recommend adjusting the higher number to make it lower.
14. Find the difference between the two extremes and divide that number in half to figure out the adjustment amount.
    
    Example: Block 1 is measuring 4.90 and Block 9 is measuring 4.70. The difference is 0.20 mm (200 microns). Divide this number in half to get 0.10 mm (100 microns). That would equate to a 1/4 turn adjustment.
     
15. Using the 3 mm Allen wrench, apply adjustments cautiously and precisely.
     
    To increase the height measurement:
        a. Turn the outer screws, or Set Screws, counter-clockwise (e. g. ¼ turn= 100 microns).
        b. Turn the inner screws, or Driving Bolts, clockwise (e. g. ¼ turn = 100 microns).
    
    To decrease the height measurement:
        a. Turn the inner screws, or Driving Bolts, counter-clockwise (e. g. ¼ turn= 100 microns).
        b. Turn the outer screws, or Set Screws, clockwise (e. g. ¼ turn = 100 microns).
     
16. To lock the adjustments in place, turn the Locking Screws two full rotations to the right.
     

Automatic Home Position Calibration

Prerequisites:

• The Load Cells have been calibrated.
• The material tray is empty
• The material tray and the build platform are wiped clean.

Procedure:

1. Go to Settings > Move & Calibration > Home Calibration > Auto Homing.
   

   

2. Press OK.
   

   

3. If you have already calibrated the platform position with this material tray, proceed as follows:
   Find the serial number or name of your material tray in the list and tap it.
4. Press Select if you want to select this material tray and proceed to work with the printer.
   Press Damaged to mark the material tray as damaged and remove it from the list.
   

   

   
    
5. Press Recalibrate.
6. In the popup confirmation screen that appears, press OK. Make sure your material tray does not contain material in it. Material residue in the material tray during the calibration will give a false reading to the sensors.
    

Add New Material Tray

If you want to add a new material tray to the list, proceed as follows:

Navigate to Settings > Move & Calibration > Home Calibration > Auto Homing > Add New Material Tray.

If your material tray has the serial number:

1. Press With S/N.
2. Find the serial number on the front of your material tray and enter it into the field on the screen that appears.
3. Make sure your material tray does not contain material in it. Material residue in the material tray during the calibration will give a false reading to the sensors. Press OK.
4. Press OK.

If your material tray does not have the serial number:

1. Press Without S/N.
2. Name your material tray and enter the name in the field on the screen that appears. The name should contain 7 digits from 0 to 9.
3. Make sure your material tray does not contain material in it. Material residue in the material tray during the calibration will give a false reading to the sensors. Press OK.
4. Press OK.
