I have an Ultimaker 2+ with Cura 2.1.2.
I'm trying to print a set of pieces with different heights. I noticed that when I put in the taller ones, they automatically scaled down to 52 mm. When I changed them back, Cura wouldn't slice the project. Trying something else, I disabled automatic scaling. When I added the > 52 mm print, it wouldn't slice. I looked through Cura settings to see if anything jumped out at me. Nothing, so I looked online. Everywhere online. The max print volume for the Ultimaker 2+ should be around 205 mm, but Cura won't let me do anything above 52 mm. I've seen some promising answers about changing certain settings, but my Cura doesn't seem to have those settings. If the solution is complex, fine, I'll work on it. If it's simple, fine, I'll smack my forehead and get it done.
