Sci-Fie

I'm sorry about the bad english... after reading thru the question I discoverd some weird grammer/sentences. I hope you can still figure out what I mean, If not please feel free to ask more information 🙂

So after a some trial and error I finaly where able to print to small plates. The problem I was having is that the printer started the first plate, printed a few layers and then started on the next one( I had two of the exact same models in one file) after tweaking and googling I got it to print both models layer by layer. Today I wanted to print a mold for a furniture piece I'm making. (Once again 2 models in one run) so far cura saved the settings I used earlier but it doesnt give the same result which translated to the printer printing 5 layers on the first model. when it goes to the second slighty different model it starts printing mid air, basically wasting filament. Which setting do I need to enable/disable/tweak to get it to print 1 layer for each model? The printer I'm using is the Creality Ender 3 pro because both me and my dad are quite new in the 3d printing stuff Tandverbinding mal.obj CE3PRO_Tandverbinding mal 2.gcode
