First test run (moai circle) failing

Put the kit together and first test of functionality today. No before experience in STL printers.

During the dry test print without resin I did not see laser. Then looked that it is on and moving and “drawing” something at the wrong place (ie it is not directed at VAT at all, but missing it). It seems to hit metal at the side of the VAT and moving around there.

So there seem to be very fundamental aiming error. Checked the cables and they seem to be in right connectors at least the first check. Also the laser position looks same as in instruction pictures.

Any advice how to proceed?

Follow the guide @johnchen sent above and it should be fixed in no time, do the center test first, and then the circle test
