Nozzle striking?
So I finally got my printer to stop jamming, basically I made sure the PTFE in the heat break was slightly longer than it should be. Problem solved! However, I am curious about a slightly less serious issue. When I start larger prints, that is when they take up a decent portion of the build plate (X,Y), I am noticing that my nozzle is dragging across the print, almost as if my Z steps are off or something. It isn't fatal, as in my prints still come out okay, but I am worried it will slowly cause damage to something. I have the latest firmware (4.0.5) on my printer and the latest Prusa Slicer. I would try Cura but I haven't seen a good profile for the mini. Is the profile wrong in Prusa Slicer?

You have to re-adjust the PINDA probe. Use a zip tie to gauge the gap between the PINDA and the bed while the Nozzle is just touching the bed.

Does it happen in certain corner or side of print? My first thought was whether X axis is parallel to bed. I know MBL should compensate for some of that, but ...

It is not the PINDA as I have done a recalibration of the machine. I wish it was as easy as one corner but it covers the entire area.
