g code out of range

I am getting this message with LinuxCNC stopped on

G01 z#5 F#7

in a subroutine. Any idea why?

Looks like you need to set the feed rate.

No change. Does the feed rate need to be outside the subprogram?

Actually the feed rate is set in the call line. But the lines you posted start with a % but do not end with one, I assumed there was more...

Try adding a % to the bottom. Or get rid of the starting % and end with a M2
and edit the call line to...
Rick G

The following runs for me after adding M2 and dropping the unmatched % but takes forever to move from Z2 at F0.05

You might want to look at some of the G code generators on the wiki

Code:

% ( Mill a hole with the center at x,y and diameter d, diameter of mill Md and depth z ) ( Parameters: x y d Md z vfeed cfeed) ( #1 #2 #3 #4 #5 #6 #7) O100 sub #8 = [#3 - #4] ( Diameter of circle to mill ) #8 = [#8 / 2] ( Radius of circle to mill ) G00 z2 G00 x [#1 - #8] y #2 G01 z#5 G17 G2 x [#1 - #8] y #2 i #8 j 0 z #5 O100 endsub O100 call [0.5000] [0.5000] [0.6110] [0.2500] [0.0000] [0.5000] [0.0500]

Running your original example I get "File ended with no percent sign" is there more?

Yes, the whole file is 8 MB. I put % at the end, no change. It still stops on G01 z #5 f0.5. The error message makes no sense so I rebooted and started over. Next step is drop the subprogram and have the program I've written to produce this file generate every circle cut directly.

Here is what causes that error:
git.linuxcnc.org/gitweb?p=linuxcnc.git;a...1c1f51c330148ca#l464

The error means that the intepreter is seeing a letter G followed by a number greater than 99.9 or is fractional by less than a than a tenth.

I confess I can't see anything meeting those criteria in your G-code snippet.

But, the error refers to an invalid G-code, not any sort of limit error.

I wonder if there is some sort of invisible character lurking in the file?

Just my 2 cents worth.

Could this just be an embedded control code in there because the files say was moved from a windows machine to linux

Open the file in Gedit and select SaveAs and Line Ending: Unix/Linux.

Edit: thanks Andy that error actually makes sense to me now. I perceived the error was trying to say a move was out of range not invalid G code used... the error could be a bit more informative if it actually printed the invalid G code.
