While this was going on, I reloaded every single profile into the new version of S3D, after changing all of those Z-Offset adjustments, tested them again, and I was on the last spool - the PETG. Ran some cleaner filament through at the PLA temp, since I was switching from PLA to PETG, and didn't want to cook any PLA into the nozzle and create a clog. Put the PETG in, heated it up to correct temp, (forgot I was working with PETG after 18 spools of PLA) and ran a 100mm purge through to clean out the cleaning filament.
Well, either the cleaning filament or 100mm of PETG going through the V4 PTFE nozzle with that much force actually pushed the nozzle further down out of the cradle. I started the final calibration print, walked over to the machine to catch the starting purge (which I normally do). As it purged I saw that the nozzle was too low and raced to get to the Emergency Stop button........
Didn't make it.
Dammitall! Now i have to start over.
