Why do the printer drive up his building plate long distance about 80mm? The original test file works well but when I slice a stl-file and printing the printtime at first for example 45minutes and after first exposure the printtime goes up to 2hour22minutes because the building plate needs much more time while she is drive up to 80mm or more and then she goes down to next exposure. I have imported the original printer settings from Junco. I think is similar to Mars Elegoo.
