In this small video, I demonstrate how I adjust the offset of a Z probe in Marlin; it is needed to have the first layer just right. You need to do this if you make repairs on the hot end that changes the probe or nozzle height, and the first time you use a probe, the rest of the time you should not have to change it. It’s the offset between the probe detection height and the correct nozzle height for the first layer.

I can't get enough of my 3D printer. I make everything and anything out of 3D filament (PLA, PETG and more). As I say a printer that is not printing is a missed opportunity. I'll be doing electronics, mechanics, computer engineering, DIY, reviews and tutorials. Subscribe to my channel, and don't forget to turn on notifications.
