Build Plate Alignment on the XiP Pro

It is essential that the build plate is aligned with the light engine top surface. A build plate that is not aligned can lead to poor first layer adhesion or damage to the LCD screen. 

The XiP Pro alignment kit should include 3 feeler gauges colored Blue (.005"), White (.0075"), Brown (.010") which are the minimum, nominal, and maximum respectively.

Please note that when checking the alignment of the build plate, the user should home the build plate using the alignment workflow on the touchscreen instead of jogging the build plate to the home position with the manual build plate alignment feature. The alignment workflow can be cancelled if alignment is still within spec. When checking alignment, don't loosen the clamp bolts or move the cam positions when prompted, and don't clamp the build plate with the lever until it has reached the home (bottom) position.

The Build Plate alignment procedure must be performed after replacement of the LCD module. To access the procedure, use the following steps:

  1. Tap Settings > Maintenance > Build Plate Alignment.
  1. The touch screen interface guides you through the process. Please follow the instructions carefully.
  1. Once the process is completed the gap around all corners between the build plate and the LCD screen should not allow brown gage to fit and blue gage should fit all locations.

We recommend you use the solid build plate for alignment because it is usually flattest.

Alignment Tips

It is good practice to place the build plate directly on the light engine (not installed in the z-axis) and check for gaps or rocking at all four corners. This is the best case alignment.

If you have moved the cams with arrows pointing all the way up or down and still need further movement to achieve the target gap, you may need to adjust slightly the position of the lower limit switch. To do this loosen the screw and rotate the limit switch body clockwise about the positioning pin to get an adjustment range with a larger gap, or counter-clockwise to get an adjustment range with a smaller gap. The adjustment range of the cams is +/- 0.4mm.
