I don't know what you guys do, but this worked great. I modified my wrench and placed it on the shaft of the spindle. I then used zZero to set the spindle to 0. For me this meant when Z = .123" the wrench was not touching the zeroing plate, when it was Z = .122" it was touching. What do you know, my zeroing plate measured to .123".
I could then swing the wrench to the other side 180 degrees and set Z = .123" and see where I was at. If I touched the plate it was too low, if I didn't I could adjust and find where it did to know how much to adjust.
There are photos later that will help this make sense.
I set the spindle out on the table so I had enough clearance for the wrench to spin and still be on the table.
I set the wrench end off to the X=0 side of Y and zero'd. This now meant that at Z=.123 then zZero input was off, at .122 it was on.
I swung the wrench 180 degrees and set Z to .123. I had a large gap under the wrench. I had to set Z to .100 to touch. So it was too low.
I raised the low side and repeated the process, Zero Z, swing, check and so on.
In about 10 minutes I had both sides at .123". I did the same for the X axis, double checked everything and that was that.
My Y axis is less than .001 off square, my X axis is less than .003 off square... and that's out at the length of the wrench!
I used my second wrench to weight down the zero plate, no other function. Yes, I know I need to resurface my spoil board, that'll come later.
Here are some photos to help this make sense...
My wrench mod is a bolt added to the end eye.
3149
I was stunned, .123"
3150
All nice and zero'd
3151
What the PC shows, touching...
3152
not touching, like magic.
3153
now at the other side not so close
3154
What my dog was doing all this time
3155
Hope that makes sense.
