I have found parts on Amazon where you can adjust the belt tension with a knob. They go in place of the roll at the end of both the X axis and the Y axis. You may want to have a look at those, I can highly recommend them.

When I am printing models with holes in the bottom, the print order is usually to print the outline and hole borders before the rest of the bottom layer is printed.
Is there a way to change the order for the bottom layer only? That way, I wouldn't have the lines that I have below the print.. ![0_1601903208651_20201005_150236.jpg]
