Raised Spindle - What a mess

I'm using v2.8.2 Linuxcnc - Debian Buster /  Gmoccapy ui
Machine is a cnc router (PrintNC)     X, YY, Z

For the last year, I have been using this machine and it has been working flawlessly
Then I decided to raise the spindle so that I could get my probe over a part I'm working
on...  That was a mistake!   I only raised the spindle a half inch...

Now when I probe bar stock (xyz), run the tool setter(M600, M6), start machining, the end mill
is cutting air about 2.5" above the bar stock.  I watch the probe routine working, each axis being
zeroed out on the dro.  

Why am I cutting air now?   Did I dink with some stored spindle height variable? 

Without your config it is not possible to answer the question, as there are to many possibilities.

You raised the spindle to get your probe over the part?
So you moved the spindle and the probe? 
In gmoccapy you can set blockheight and probe hight etc. have you checked your settings?

Thanks Norbert. Yes, I raised the spindle up a half inch to get the probe over the part. That's it.

Now when I use the probe, and tool setter, then start a job, the end mill is cutting air about 2"+ above the part. I have checked the post a number of times.

I'm wondering if there is a variable set somewhere that has the old spindle height.

Here is what I know for sure
This all started when I raised my spindle a half inch up in it's mount

From that time, I have NOT been able to use my probe where I don't end up cutting air after using M600, M6 T99

If I bypass the probe, and set the tool manually, still using M600, M6 T99, the job runs fine.

Yes, the probe routine is setting the three axis's to zero on the DRO

Something changed when I raised the spindle up. This is what started the issue with my machine.

To me, the M6 routine isn't calculating the offset now. And I have no idea. If I run a second tool change on the job I'm running, the Z will be off.

 

Thank you Tommy...  Attached is my config

In response to your comments, I don't recall setting any spindle height when I first set up the machine.
I have a limit switch at the top of Z, and set the min / max limits in the .ini file
I have absolutely no idea where I would change the spindle height beyond this

Thanks for looking at this for me

Tommy, maybe you are telling me what the issue is... Where is the probing offset stored? Maybe this is as simple as clearing that offset. I just don't know how that is stored.

(Solved)

I went back to the Fusion 360 post and see something I haven't seen before in my posts...

G43 Z15. H10

This line is looking for tool compensation... I don't have any compensation in my tool file, so I don't know why this caused the issue. But, I changed the line to G0 Z15. F500. and my machine works again!!!!!!!!!!!
