Clear buildplate with fan at start

An option along with level/timelapse/ams:

“Blow debris from plate”

Which would move the print head to the far right rear of the plate, lower it to a few mm above the build plate, with the part fan blowing 100%, make a first pass from -y to +y (back to front) and back, then repeat the y motion while also moving the printhead from right to left across the plate, keeping the fan running the entire time, blowing any small pieces off debris off the plate.

Why?

I often see the printer go through its various motions prior to bed-levelling, and dropping some small piece of plastic that ends up getting moved around on the plate by the hot end later or even interfering with the levelling process.

If the motion is fast enough, you may want to do it again after the levelling process, incase any more debris oozed/fell from the print head during levelling.

This isn’t to remove debris that was present prior to start of printing, but strands/strings/etc that end up on the build plate during the print-start motions.

What if the material is stuck onto the plate?

To be candid, I’m not sure I’d vote to have this on the priority list. There are many other important oversights that Bambu needs to address, and this particular feature can be accomplished with a Gcode snippet if one is motivated enough.
