First Layer Calibration Suggestion
I have an old MK3 (To be upgraded to a MK3S+ soon). I am trying to get the first layer calibration to be as close as possible. I have had run the calibration multiple times for each of multiple sheets (satin, metal, smooth, etc.)
It would be extremely helpful if at the end of the calibration a menu popped like this:
Save New Value
Use Old Value
Re-Run First Layer Calibration
By having the ability to run the first layer calibration before turning of the filament and bed heaters and not having to negotiate multiple menus to get back to the function would speed up those of us who are trying to tweak our Z alignment or are having trouble getting it right.
Also, better examples in the manual of what the ZIG-ZAG looks like for too high and too low would help a lot.

I would also add, an abort calibration option like you have when printing from CD.
What do the Speed Percentage and Time remaining on the info screen mean when running First Layer Calibration?
RE: First Layer Calibration Suggestion
Use the built in Z level routine to get in the general area of a correct Z height. You want the corners of the long lines to be square and stuck to the print sheet well enough that you can’t move them with your finger.
To fine tune your Z height, read this post, download the files, and do a print for your material. You can adjust the Z height halfway through the print. There’s a buzzer that will sound at the halfway point to remind you. Once you get a feel for where you are, you can adjust the height 4-5 times during one print.
When you think you’re there, print one entire sheet at the same Z height. When the print cools, remove it and examine the top and bottom surfaces. Bend it in half and at several locations along the layer lines: it should hold together sand not crack or break at any location. Good luck.
Cheers

This method worked perfectly for me!!!
