Hi I hope you can help . I made an stl file in opens cad. It is a simple grid 18 holes x 5 holes. 30mm x 10mm x 5mm. I imported it into cura, it shows on the bed but shows 0 print time and 0 material used. In view mode it shows in normal x-ray and transparent but in layers it disappears. The scale shows the correct sizes
Thanks Gerry
