Z axis exceeded -- I know the cause

[Fueler1]

But not the cure.
As seen in the photo the issue is with the designated tool. Top Right.
I fussed around with the tool library both in Centroid and the Fusion file. Everything looks as it should.
Looking for the obscure.
Thanks

Your Z Reference for tool measurement is 0.0 in machine coordinates (home).

Therefore your tool offsets are measured down from home, to whatever surface you are using to measure tools.

Your measured offset for tool 160, H160, is -20.86. That says that you had to bring the head down 20.86 inches to touch T160 to the measuring surface,

Your Z axis Part Zero in G54 is -14.59. That says that, if you were using the Reference Tool (an imaginary tool that is 20.86" longer than T160), you would have to bring the Z down 14.59" to touch your work surface. This is almost certainly not right. If Z has to come 14.59" down from home to touch the work surface with the reference tool, then Z would have to come down 35.45" from home to reach the work surface with T160.

My guess is that, when you went to set your Z axis Part Zero, you neglected to enter the correct tool number for the tool you used to locate the surface. Alternately, you entered the correct tool number, but had not yet measured the height offset for that tool, so its H value was still 0.0.

Try loading T160 and jogging it down to the work surface; going to the Part Setup screen for Z; entering Part Position = 0.0 and Tool Number = 160; and pressing F10/Set. Then try running the job again.
