This is a remix of xx77Chris77xx's bed level test. I scaled it down to the size of Monoprice select mini's bed. When this test is done, look at each square. They should look the same, thats the most important part. If the squares's infill looks sharp and jagged, raise the bed on that corner. If the infill looks squashed, lower the bed in that corner. Keep printing this and leveling until each square has a nice infill. Note: the most important part is that eache square's infill looks the same.
