I think this has more to do with the software part of this. I've printed lots of items but I've never seen this before. Using Simplify3D, I drop a file into the window where I can see what the model is and it looks correct. The first time I printed it it only printed the bottom part of the model. After reloading the model and going into Preview mode, I saw that it wasn't the printer stopping prematurely but that the bottom part was all it was going to print in the first place. I tried rotating the model in a few directions and checking the Preview and found that it was missing different parts each time depending on which way it was rotated. It appears that something is getting lost when I click the Prepare to Print button. I've never seen this before. It seems specific to the model. Anyone have any ideas?
