Work with probe

GOOD AFTERNOON! I use linuxCNC for milling through the AXIS 2.7.15 program. The programm has a PROBE function to set the height of the tool along the z-axis. The function worked fine. And suddenly it stopped. I tried to work out various control programs, including those that were already in operation. Each time axis gives an error: "EOF in file\path to NC file\seeking o-word: <zero_on_z> from line: 0". I'm not an advanced linux user at all. And English is not my native. If someone has something to say how to fix the problem, please use it in a simpler way, without abbreviations and slang specifics. I think this is a linux programm bug.I tried to change the ini and hal files according to the instructions on the Internet, but without result. And I don't know how to find and fix it. Additional information may be required to restore equipment to working order? Thanks in advance.

I've found a file in my directory for copies with this line: ... o<zero_on_z> sub ... Maybe that is what suits him? But where should I put in or write in this file?

problem's been solved, thanks for silence

What am I doing wrong?I keep getting this error 
 
 

Hi Ho,

so I write here since it is linked on GitHub. Disclaimer I am  total new to CNC stuff so have patience with me.

I have LInuxCNC 2.8.4, Gmoccapy and use Probe Screen for LinuxCNC 2.8. I use a touch Probe and a Touch Plate. I "or" connected the input signals in HAL and debounced one of them. Everything is working as I would suspect except:

After a manual tool change and the subsequent probing operation it finishes above my touch plate. Then the programmed gcode resumes and wants to move first in Z to the working piece. This would result in a crash into my touch plate. 

My fast fix was to add a move operation into gcode directly after M6. But that is not nice… 

So my question is how to tackle the problem?
1. Do I configure my FreeCAD post processeor to add a move after every manual tool change?
2. Do I add a Move at the end of /psng/macros/_probe_tool.ngc?
3. Did I overlook somewhere a configuration option? Which normally handles this problematic. 

Cheerio and Thanks in advance

The correct place to add the move would be in the remap .ngc file. Then it will always get run, even if you forget.
