I have been using Cura since building my first 3D printer about a month ago. It works great except it won’t pint on the back third or so of the bed. My bed is 290mm. If I center and try to print an item that say is 200mm long, it fill print the front 2/3 or so and then neatly truncates the print and just does not do the back third. The designs look good on Cura but they won’t print the whole thing on the bed. Any ideas what this might be?
