In our latest version of UP Studio, we brought back one of its most wanted features, Vertical Calibration. Its main purpose is to ensure all three axes are perpendicular to each other in order to guarantee consistent, high-quality prints.
UP Studio achieves vertical calibration by printing a build-in calibration model.
Before proceed to printing the model, make sure following steps are done:
- Level the print bed using the 9-point matrix leveling
- uncheck no raft
- uncheck no support
- set layer thickness to 0.2mm or 0.25mm
You do not need to resize the model for different UP printers.
After calibration model is finished, you can take out the build plate from the machine, but don’t remove the object from the build plate. In the software, find Vertical Calibration under Model Calibration. Click Default to reset all the values before entering any new values into the edit fields.
Perform X/Y measurements. Use a thin ruler or a Vernier scale to measure the diagonal length of the model from one corner to the opposite corner, as shown in the figure below for X1. Then, do the same for X2.
The length of the two diagonals should be 124 mm.
Enter the values for X1 and X2 into the software.
Figures 1 and 2. Measure and Enter X1 and X2
Click the Confirm button to complete the X/Y axis calibration. The software will round those values to the nearest tenth.
Click the dropdown in the upper left to shift to X/Z mode. X/Z calibration requires measurement of the L-shapes. First, remove the L-shape from the Front position from the build plate and peel them off the raft.
Next, use a right angle ruler as shown in Figure 3 and push the ruler against the corner of the L-shapes. If the angle is right angle, then enter 0 to the field.
Figures 3 and 4. Zero Z Value
If you find an L-shape that is not 90 degrees, the angle must be adjusted. To clarify, you are looking for a gap between the ruler and the L-shaped object.
The gap will either be at the top of the L-Shape (an obtuse angle) or at the bottom corner, between the ruler and L-Shape (an acute angle). Use another ruler to measure the gap. As shown below, enter the Z value as a negative number if the angle is obtuse. Enter it as a positive number if the angle is acute.
Figure 4. Obtuse Angle, Z value will be negative.
Figure 5. Acute Angle, Z value will be positive.
The H value is literally a measurement of the L-shape’s height between the bottom of the ruler while sitting on the L-shape’s base and top of the vertical part of the L-shape. Ideally, it is 40.0 mm, but it may not be. Enter the true height measurement into the H value field.
To finish the calibration, do not forget to click the Confirm button.
For UP Studio 2.X only XY and XZ planes can be calibrated. the YZ plane cannot be calibrated.
If an error message appears or if you discover all L-shapes are leaning different directions on the print surface, please contact us directly at email@example.com for further assistance.
