Preface
When tuning settings on my printer I do a lot of test prints. For best adhesion and dimensional accuracy you want to probe a bed mesh which stays valid as long as you don’t move the bed.
I happen to be very impatient so I take the build plate off of the print bed to have my print ten precious minutes earlier. Now, it so happens that probing the bed with the original probe — slowly; point, by, point — takes about five minutes which can be a significant slice of the printing time on short test prints. One day, while watching YouTube, the existence of eddy current probes was brought to my attention. When I saw the ability to scan the bed in mere seconds I was already sold.
