LinuxCNC 2.5.0
CNC3020T modified to detect contact between tool and copper on PCB and send this signal to LinuxCNC probe input.

The part program included below generates the message "probe point too close to current position near line 19" when trying to open the file.   Line 19 is the G38.2 line.

I had this problem with a new file I had created so I went back to a file from which I had produced a PCB without this error.
But now this older file produces the same message.

What is going on?
How do I fix it?

Current position and probing target is 0
Set Z to a positive value or probing to a negative value
