imageprint not aligne

[schneck007 1]

Yesterday i tried to print a jpg image. This first layer from the cube works great, but when he have to close the last layer, they not aligne anymore. the first print was missing 0.5 cm at top and at the bottom the was 0.5 cm to much.

with 2 second print from the some file the some thing happens with 5cm. At top 5cm was missing and at the bottom there was 5 cm to much

why does this happend and how to prevent this

Print from jpeg? I dont' think that's the feature you want. If you want to print a cuboid (box) I recommend instead you download a cube from thingiverse and then set the x,y,z dimensions exactly as you want.

Printing from jpeg is tricky. There are similar features in thingiverse - see "lithopane" if this is truly what you want.
