Is First Layer Calibration any different to Printing a flat object
I am still a little confused about the relationship between the First Layer Calibration option and Live Adjust.
Am I right in thinking that when I get my level right using First Layer Calibration option, I don't need to do it again, and instead can just use "Live Adjust" whilst printing?
Further more, can I achieve the same by printing a flat, 2D object, and find the Z height using "Live Adjust" rather than using "First Layer Calibration' option"?.
Does the First Layer Calibration option do anything special, or does its simply print the "snake" and give you Live Adjust at the same time?

Yes, with the caveat that the flat 2D object should be exactly 1 layer high. It's common to print whatever shape you want to use as a single 0.20mm layer. If you want to use material temps or nozzle sizes that don't match up with the example prints, you can just create a squared shape of your own easily enough. I like to use a 75x75x0.20mm square (like in the "Life Adjust" thread) with rectilinear solid infill for initial adjustment, then a larger 240x200x0.20mm rectangle with concentric infill to test bed level at the edges. No need to let this one complete, just a few rings to verify filament is adhering near the edges.

You may end up repeating the process if you change nozzles, print sheets (e.g. using another brand) or filament type.

Re: Is First Layer Calibration any different to Printing a flat object
Understood.. My plan was to make a square which was 1 layer thick for the job as the "First Layer Calibration" tool is horrible.
I have been a little tentative as I assume its possible to gouge the bed if you make Z too low, so I have been very (Too?) carful..
my assumption was that once you have some Z numbers for different bed and filaments, you can simply enter these (Using Live Adjust) every time you change something?

Thank you. That is extremely helpful, and easy to understand.
That's "MISTER Old Fart" to you!

There is however a code in the first layer calibration code that lets the printer know that calibration has been done

Which are simple squares at 0.2mm layer height.
