Reading tool table in G-Code

Is there a way to determine if there is a Z value in the tool table for the current tool in G-Code?

I have been looking at the parameters and GCode but nothing seems to provide that data. I have my manual tool change M6 remap working. Each tool gets measured during the tool change. Great, that works. But since I do have TTS tool holders for most tools I just need to measure the non-fixed length tools like drill bits in a chuck. I thought that if I could detect that a tool was one of the fixed length ones I could skip the touch-off on the tool-setter. I thought that I could look at the Z offset and if it is zero then measure the tool. Otherwise use the offset from the tool table

Thanks

#5403 shows the Z length of the loaded tool.

So, to get the length of a different tool, you could try:

#2 = 22 (tool to query)
#1 = #5400
M6 T#2 G43
(DEBUG, Tool #2 Length is #5403)
M6 T#1 G43

Thanks Andy. That worked. I had the right Idea. I was just looking at the wrong parameter. I was looking at #5213.

Thanks again. I really appreciate the help and hope to pay it forward someday.
