X1 Carbon Newbie Question

Hello, I received my X1 Carbon yesterday and so far it’s been a blast beginning my journey into 3d printing. I have never done any 3d printing before so this is all new to me and I have taken some time over the past few weeks trying to read up on as much as possible. Yesterday I printed a few models via Bambu Studio and I was wondering why all the models I print generate these additional lines at the bottom of the print area? They clean up easily however I am curious what they are? Thanks

@Dudditz ,

Welcome to the community. Those extra lines are from the flow calibration step. You can turn them off when you send the print job to the printer as they don’t need to run every time. That said, I leave them on unless I am printing on a textured PEI sheet.

Thank you for the clarification.
