What you are doing seems similar to the way I sometimes enter offsets but there are differences and I am a bit puzzled.
You 'touch off tools to height block' which suggests you take the tool down until it is touching the height block and then press Tool Ofset Mesur.
Is this what you do?
What do you mean by 'take the gauge block into account'?
Why do you touch the position senor to the top of the table if you have already touched off to the top of the gauge block?
You 'set origin on z'.
What is this value?
Then you 'touch position sensor to top of work piece' and 'input the measured height into the G54 Z offset'.
As far as I can see you have entered the total distance from the table to the top of the workpiece into the G54 Z offset.
And you have entered the Z position to the top of the gauge block into the tool offset.
It seems to me what should be entered into the G54 Z offset is the difference in height between the top of the gauge block and the top of the work in this manner: (Star with zero in the G54 Z offset)
Touch off tools to gauge block and enter the tool offsets using Tool Ofset Mesur.
Using a gauge mounted in the spindle:
First, find the Z position of the top of the gauge block at gauge zero.
Second, find the Z position of the top of the workpiece at gauge zero.
Enter the difference between these two Z positions into the G54 Z offset.
An open mind is a virtue...so long as all the common sense has not leaked out.
