    It depends on what you are offsetting from. I use a USB Microscope to figure out my offsets and all of my tools are referenced from the Z switch so I can change any of them at any time.

    I highly recommend doing something like this. I can reset all my tools in about 30 minutes now at a much higher precision than I ever could with the vernier method.

    I can attest to the microscope technique being the most painless, though I only use it for X/Y and then I use a second microswitch temporarily fixed to the bed for the height offset. One thing I like when using RRF3 is you can do things like this:

    Code:
    G10 P0 X23.00 Y41.00 Z-5.41
    G10 P1 X{tools[0].offsets[0] + 0.11} Y{tools[0].offsets[1] + 0.10} Z{tools[0].offsets[2] + 0.04}
    G10 P2 X{tools[0].offsets[0] + 0.15} Y{tools[0].offsets[1] + 0.05} Z{tools[0].offsets[2] + 0.17}
    G10 P3 X{tools[0].offsets[0] - 0.01} Y{tools[0].offsets[1] - 0.15} Z{tools[0].offsets[2] - 0.03}
    
    So that all of my offsets are relative to the first tool offset, so I can use the calculated offsets directly rather than calculating them (which obviously isn't hard, just removes a step).

    Any links to such an item? I feel behind the times
