I have been having the same problem. After going through the whole manual step by step and adjusting the z-axis, it still is making that grinding sound when it goes into the resin. After looking at a bunch of other people's responses, it looks like it is a problem with adjusting the z-axis 0 and making sure the build plate is not pushing on the screen. My z-axis works moving up and down manually and is doing fine in all of the other aspects. I have even tried realigning the z-axis 0 two times now. The first time, I followed the manual and used a sheet of paper and made so that it is just tight enough that I can still pull the paper out. The second time, I followed some responses that I found online and moved it up about 1.5 mm (which is a lot). It is still making that sound and having that problem. This is a new Mars 2 Pro and I am just trying to print the Rook file that comes with the printer. Please help!
