How to Level the Build Plate on a Bottom-up 3D Printer

About: https://www.chitubox.com/download.html

Maybe plate leveling is a somewhat cockamamie process because you pretty much have to re-level the plate if you have moved your vat or plate and sometimes it's hard to get it perfect. But while using a bottom-up 3D printer, it is necessary to periodically calibrate or level the build plate before printing.

Step 1: Why Do You Need to Level the Build Plate?

If the build plate is not flat, you will likely have adhesion problems and possible failures especially when you are attempting large prints.

And the raft or bottom will aslo not be flat if the build plate not being leveled properly. The layers that are closely connected to the build plate will be thinker. The raft or bottom could have looked slant which may even affect the accuracy of the print.

The slant raft or bottom may cause the failures for the generation of supports. Then the print job fails. Fortunately, the print below was finally successful even some supports are missing.

Step 2: How to Level the Build Plate on a Resin 3D Printer?

- Press the Z height reset button on the screen to lower the build plate until it goes for home position at the correct height

- Loosen the leveling screws on the build platform

- Check whether the build plate is flat(if there are resin overflows in the vat, you can press the build plate to touch the screen)

- Tighten the leveling screws on the build platform

Also you can place a piece of printer paper on the LCD screen, then lower the build plate until you feel resistance when you move the paper.

    Do you have any pictures of the leveling process? I am having a little bit of a hard time understanding what you mean about feeling resistance on the paper.
