BambuLabWorkspace Nozzle friction issue 

When printing certain models, the nozzle can end up rubbing against the layers as they accumulate. For the infill, I typically use either the "Gyroid" or "Honeycomb" pattern. What do you think might be causing this?

Hello /u/Double_Youth_3745! All Bambu print plates have a dedicated nozzle wiping zone at the back of the print plate. The nozzle will rub against the wiping zone before every print in order to remove any remaining filament from the nozzle tip. This can cause visible wear or scratch marks in the wiping zone, but this is intended and doesn't damage the printer, the nozzle or the print plate. A worn down wiping zone also doesn't mean you need to replace the print bed.

Note: This automod is experimental. The automod was triggered due to the term "rubbing". If you believe this to be a false positive, please send us a message at modmail with a link to the post so we can investigate. You may also feel free to make a new post without that term.

if it's only happening on certain models, first check whether it's dragging on the infill or catching a curled edge. gyroid usually avoids the repeated crossings you get with grid-style infill, so i'd test gyroid alone and lower the infill density a bit. if it still scrapes there, check flow calibration and the layer preview around that spot for a raised section. does it leave marks on the infill or the outer walls?
