Nozzle crashes into heatbed after nozzle switch
Hello,
I have just switched from the original nozzle that came with the Mini+, a 0.4, to a new nozzle, 0.6, V6 from the Prusa store.
I followed the procedure described in the docs, and also watched a video to make sure I understand the process. I think it's pretty straightforward, I didn't find it hard and do not think I skipped any step. I was pretty gentle and do not remember hitting anything.
Now when I try bed leveling the Z axis goes so low that the nozzle crashes into the heat bed to such a point that I have to quickly reset the printer before it damages the heat bed. It pushes hard on it.
Did I miss something ? I thought the P.I.N.D.A would avoid the heat bed. Could I accidentally damage it somehow while switching the nozzle ? How can I test that it works ? How can I fix that ?
Thanks

Well, I solved it easily. I reset the Z-length is the experimental settings. Then I did a Z calibration. And finally a mesh bed leveling. And now it stops where it should.
The heat bed seems a bit bent from the initial crash. I hope it won't affect subsequent prints. Or I'll switch to a new one.

RE: Nozzle crashes into heatbed after nozzle switch
You probably need to keep the Z length as is and move SuperPinda sensor lower by one or two full turns ( apparently it is too high to trigger bed detection because V6 nozzle os longer or installed lower), then do first layer Z offset calibrations starting with high positive number to avoid collisions and then move it closer to zero or a bit of negative value.
