Hot End Dive Bombing Build Plate

So I just got my printer set up last Saturday. I successfully printed the Prusa logo and the vase that came on the SD card. I have a successful print from an STL file that I slaves myself.

 

But now my printer has learned a new trick. After printing for a few hours, it'll try to Dive bomb the build plate. I was in the middle of printing another vase when it knocked the print out of the way and drive the nozzle right into the skirt path. Last couple of tries the nozzle or extruder body got caught on the print itself but the printer was still trying to push itself down to the bed.

I'm baffled

Does this happen when you print one of the pre-sliced gcode example files that shipped with the printer?

If not, there may be something amiss in your settings. Save your print and settings in a 3MF project file, zip it up, and attach it to a reply here so we can look at everything to make better suggestions.

Hello an welcome to the Prusaforum!

A video would be helpful. Possibly, the printer tries to re-reference after a crash detection and continue printing afterwards. The reason for a crash can be incorrect slicer settings such as over-extrusion or stiff linear guides, etc....

Here's the latest one that failed: reservoir

This one I caught in the act of failing and wish I had a video of it- blame 5 am grogginess lol. The print itself was holding the hot end back from the build plate.

I didn't change much of anything from the defaults besides temps and shells.
