In our latest UP Studio software, we brought back one of the most wanted features, Vertical Calibration, whose main purpose is to ensure all three axis perpendicular to each other in order to guarantee consistent high quality prints.
UP Studio achieves the vertical calibration by printing a special STL model, VC.stl, that you can download it from our website here. Make sure to uncheck the “No Support” and “No Raft” options, and you do not need to resize the model for different UP 3D Printer. It was designed to fit all the UP 3D Printers.
The recommended z-axis resolution setting for the VC.stl is 0.2 mm or 0.25 mm.
After the print is finished, you can take out the build plate, but don’t remove the object if you are using an UP BOX+ or UP mini 2.
In the software, find the “Vertical Calibration” under Calibration. Click “Default”, before entering any new values into the edit fields.
Use a thin ruler or a vernier scale to measure the diagonal length of the model (from the outer edge to the other outer edge) 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 value of X1 and X2 in the software.
Click the ‘Confirm’ button to complete the XY axis calibration. The software will round those values to the nearest tenth.
XZ calibration needs to measure the L-shaped model in the VC.stl print out. First, you need to remove the L-shaped from the build plate and peel off its raft, then find a right angle ruler as shown in the picture and push the ruler against the corner of the L-shaped, and measure the corner.
If the angle of the corner of the L-shaped is 90 degrees, enter ‘0’ in the Z value in the software. You can find the length of the L-shaped object now from the ruler, and enter the value in the H edit field. The designed value for H is 40mm.
If a gap between the ruler and the L-shaped object exists, as shown in figure 3.2 and 3.4, the value of the angle of the corner is not 90 degrees.
Use another ruler to measure the gap between the L-shaped and the first ruler as shown in figure 3.2 and 3.4. Enter the measured value with a minus sign as a negative value in the Z edit field if the gap is at the upper portion, like in figure 3.2; or enter the measured value in the Z edit field if the gap is at the lower portion as shown in figure 3.4.
In our case, for figure 3.2, the value of Z entered is -1.5mm, and for figure 3.4, it is 1.5.
To finish the calibration, do not forget to click the “Confirm” button before you close the dialog.
