Whenever my printer running a stock creality version of marlin on a v4.2.7 board ender 3 pro and a raspi running OP 180 and this is used to exclude a region - say a tail of a dragon you wish to skip - it tends to miss a layer or two. My print just finished measuring 6.21mm high whilst it should of been 6.82mm, oh yeah layers are 0.2. In this case it failed on one object so I excluded it 20% into printjob.
