I have a very weird problem. I have a pawn I want to print for a game. Now when I print one of them, it works fine, but when i print multiple, the top layers are all squished together. The pawn is 1cm high, but when i print the 3 at once, it is only half the height, like the z-axis stopped working halfway through the print. When i print 2 of them, the total height is around 7mm
I tought maybe when the printer runs too hot or somehting, but when manually start the one object 3 times in a row, it also works fine.
I use the same STL file, and the same printer settings (in Slic3r), i just added 2 more identical objects before exporting the G-code, yet when I print them, they are all messed up. IMG_20181105_192457|666x500

Could you attach a link to the picture? The first one you’ve attached looks like it hasn’t worked correctly.

It does sound like an issue with either the z axis, or the g-code itself. If you could upload the gcode somewhere that we can download it, we may find the issue there as well.
