Faster QUAD_GANTRY_LEVEL Macro

Macros

This works perfectly for me, definitely is an improvement over the standard. I did add the suggestion to reference z-Offset as that seems to be the safe play here. Appreciate it!

not to take this post but couldn’t find a place to put the info
i switched from eddy_ng to native eddy support with tap after latest updates to klipper broke the eddy-ng scripts.

after setting up the minimal calibrations (current etc) i found that QCL was slow compared to eddy-ng ways of doing.

it implemented also the course and fine QCL commands (or atleast it gave a config like the macro showed in at top)

to get it to run it like eddy-ng i use PROBE_SPEED=20 LIFT_SPEED=20 SAMPLES=1 with the course QCL. this lowers the eddy probe to it desired height given in the desend_z parameter in the config but with higher speeds.

after that i do the fine QCL with method=scan
instead of probing it is scanning the corners making it allot faster.
