My 3d printer makes smell before the fillament is even in, is this normal?

I have a BIQU B1, and I tried to preheat it in order to level the bed and fill PLA instead. But before I even leveled the bed the printer started making smell, is this normal?

It depends on the smell and where it's coming from.  A new machine might give off some odors the first couple of times it is used.  Most PLA's don't have much of an odor but white PLA does.

The smell of burning PVC insulation is very acrid and is a BAD THING.  If that is the smell then shut it down and open up the Mainboard compartment and check all the screw-type connectors for any discoloration.  On the Creality machines the main 24volt power line connector can develop a "high resistance" condition causing it to burn.  The main power supply can also develop problems.

Just using your nose to find the source of the odor can help.  If it is coming from the mainboard or power supply areas it can be a serious problem and cannot be ignored.

Thank you (: You said it might come from a new printer, but is it possible before the fillament is in? Also is it possible if the printer is not new, but it is the first time it is being used?

It could be the printer was tested in the factory, and the test-procedure left some material in the hotend. But in any case, it would make more sense to inform if you should worry about this from BIQU support, or a community of BIQU users.
