I support this improvement - and hope that someone will produce a PR to implement it in the JSON that creates the file.

Can I also ask that the code is improved to ask for the range of frequencies to cover (i.e. lower and upper frequencies) in both types of calibration pattern, in order to allow you to zoom in on the frequency range in question and thus be able to make a more accurate measurement?

Also, the current tool does a constant zigzag shape and varies the feedrate to get the frequency. I was having trouble actually seeing the vibrations on the bedslinger movements on my printer so I tried swapping the X and Y deltas for each step of the zigzag whilst keeping the feedrates the same. (Pythagorus tells us that the line length is the same by swapping X and Y deltas, and so for the same feedrates then the zigzags will take the same time to print and be the same frequencies, the only difference being the magnitude of the vibrations.) It would be helpful, I think, if the tool also allows you to specify the magnitude of vibrations and for it to calculate the appropriate feedrates to match the amplitude and the frequency range.
