Run-from-line and v.2.7.3

Also read it but not sure what the result was.
No question that you are not getting the expected results from run from line.

If I recall the biggest problem was that z dropped down and then dragged across the work piece sometimes moving it.
So does the modified pre probe, probe, post probe sub allow the machine to go to the correct location without dragging the tip across the work?

The biggest problem with LinuxCNC v.2.7.3 is the probing when it has not been commanded to do it. The modified Pre/Probe/Post sub only helped me discover that LinuxCNC is also considering other lines prior to the run-from-line. So depending on code prior to the run-from-line can determine if I can salvage a job. It appears that I am not the only one who has noticed this. It might not be an ongoing problem for anyone else, but that doesn't mean it should be ignored, either. That's my opinion, at least.

When I don't want to scrap cutting material, I run v.2.7.0. That version does not produce the unwanted actions on the seemingly exact same code.

I agree. This is a bug.
When I said I had no idea what was going on, I meant that I don't know what the underlying cause is, and so am not in a position to _fix_ the bug.

I think everyone agrees it is a bug. You might want to check if a bug report has already been filed. If not you may want to file one. The testing you have done should help find the problem.

In the mean time we were hoping to find a work around that might help you.

As most of the programs I run use subs and they are known to not work well with run from line I never use it. I find it safer to edit the file and reload it to complete the work.

Thanks. I wasn't sure it was a bug or if it was just me. I will post a bug report.
