Hi, just wondering how useful you find the jerky zick zack move. I notice that you have it commented out (or its not there) on some profiles, especially Ender-3 BLtouch printer profile.

Hello, It's disable on other for safety, if nozzle goes under bed it can crash and make damage somewhere. It's not very usefull since it need be very close from bed, and i can't provide that on universal profiles. The purge line is ok. It would be more usefull if your printer had a cleaning zone with brushes or something to clean nozzle.
