Call external subroutine not working in recent versions of LCNC

Attached toolchange file

100% failure rate with the scenario I indicated



And again.. my revision of Axis code is pre1-4559

It's interesting to note that the toolchange3.ngc ALSO has the % front and back

Well, going to the documentation, they do not show a % in a called file. BUT, they do show a m2 ending. Elsewhere, they do say that a file must contain a Leading % and and ending % OR a terminating M2. Since the docs don't specifically forbid using a file structure similar to the primary files, I would think that the % in the subroutine file should be treated as a valid condition. Unless I missed the doc that forbade the leading and trailing % in a subroutine, I would think a subroutine file would / should be able to follow the same rules.. I believe this all worked in 2.7.3, and I didn't have the issue till 2.8 came out, but I do not want to go back to try it. I still think it is a "quirk defect" and should be resolved by code, or by a documentation statement.

Thank you for your patience and assistance.

Oh, and since the Post processor is generating the % front and back, then any subroutines I generate, and I do have a few, are going to have the % front and back. Yes, I could change the post processor.. but ...... Consistency in format is always a great coding mantra.

May I then assume that you will enter a defect on this topic into the LinuxCNC stream?

Also, I started to go through the sample GCode that is supplied in the sample directory, and a few of them will not load correctly anymore. If I have time today, I will make a list. I thought LinuxCNC had regression test cases? I would create a separate topic for that issue.

No, the bug report ( defect ) is what I assumed would be done. I am just going to the shop to go through the samples. The few I checked out yesterday said something like "Unexpected character b in around line 26 ... ) I will be detailed today.
Thank you'
