Hi all,

Need some help on how to use incremental programming (Gcode G91).

Tried to uncheck the "Export absolute coordinate" in the software config / output options section of the postprocessor configuration window but still get G40 (absolute programming) at beginning of export file.

Did I miss something somewhere?

Thanks for your help.

Francois

Sorry, i think this is a bug that you found. I guess the G40 is a typo and you mean G90, Right? Can you please create a Issue explaining it and hopefully we will find someone digging into it. Is the Code in general working and exporting incremental values as expected? Did you try to Workaround by defining G90 instead of G91 in the postprocessor window?

Regards

Christian

Hi Christian,

Thanks for your answer. I made more configuration tests to figure out what was wrong.

Indeed I found that using the default file postpro_config.cfg works fine with the "Export absolute coordinate" option. Indeed when I use my own file named actiled_config.cfg it does not work despite files are exactly same (compared with winmerge). Using my own config file always keeps the last configuration (G90 or G91) applied by postpro_config.cfg. Very strange!

Regards,

Francois

Hi Christian,

I think I have found the root cause of this strange behavior. It is linked to the fact there are many .cfg files inside the .config/postpro_config/ folder.

If I keep only one file in config/postpro_config AND also in config/ folders everything runs smoothly as expected.

It appears all config files are mixed leading to options override depending of cfg files content.

Note that bug #105 may be generated by same issue as the following option "Perform cutter compensation outside the piece" was checked in one of the file. But I'll investigate that later.
