Solution: 1) Turn on the heating function of the device
2) Lengthen the time of "Delay after stencil settling" and "Delay after recoater movement" in iBuild software parameters

Q2:Broken printing samples only appear on the left or right side of the screen
Cause: The blade heights on the left and right of the recoater are inconsistent
Solution: Adjust the height of the blade on the left and right of the recoater
Broken printing samples only appear in the front and back or a corner of the screen
Cause: The marble platform is not level
Solution: Adjust the level of the marble platform and adjust the height of the recoater
Q3:The printing sample located in a specific position on the platform is partially broken
Cause: T-Theta is dirty
Solution: Clean the lens of T-Theta

Q4:The printing sample is not well formed or the holes details of the printing sample are not well printed out,or the edges are cured with excess flakes
Cause 1:  The lens are dirty from reflection mirrors, beam expander module, galvanometer and F-theta.
Solution: Inspect the lens and clean it.
Cause 2:  The laser window is damaged
Solution: Replace the lens of the laser. 

Q5:Prints are staggered or torn apart
Cause 1: The platform is loose or the z-axis coupling is loose
Solution: Reinstall the locking screen plate and lock the z-axis coupling
Cause 2: The device is turned on to heat, and the temperature is unstable
Solution: contact with the manufacturer or turn off heating.

Q6:The print sample comes out with pits on the top surface
Cause: The surface temperature of the print is too high
Solutions:1) Reduce the laser power and speed up the scanning speed
2)  Increase the value of the parameter "Delay after laser scanning" in the iBuild software

6.The Printing sample surface is peeling or bubbling

Q1:The Printing sample surface is peeling or bubbling
Cause: The distance between The distance between the outer contour and the solid is too far
Solution: Decrease the value of "Transition Area Width" in iBuild software parameters

Q2:Peeling, blisters appear in only one or two directions around the printing sample
Cause: The spot is ellipse or the size spot is not concentric

Cause: The distance between  the outer contour and the solid is too far
Solution: Properly increase the "transition area width" in the iBuild software parameters

Q4:There are good textures in two directions, and bad textures in the two directions
Cause: spot ellipse
Solution: Recalibrate the light path

Q5:Printing lines appear between layers
Problem: The plane of the print part is not parallel to the bottom surface of the platform when the part is placed, and the inclination angle is too small.
Solution: Rearrange the printed model to ensure that the bottom of the model is parallel to the platform or tilted more than 45°.
