08:48 AM probotix: gentlemen, there used to be a forum page for a mysql based ngc file loader for axis, but it seems to have disappeared. any ideas?
08:49 AM jepler: https://forum.linuxcnc.org/21-axis/1004-axis-database-connectivity ?
08:49 AM jepler: source: I googled site:forum.linuxcnc.org mysql
08:50 AM probotix: wonder why the site search wouldn't provide the same result??
08:50 AM archivist: not entirely sensible to hold files in a database, names and where they are is better
08:50 AM jepler: probotix: it also shows up with site search http://forum.linuxcnc.org/forum/search?query=mysql&searchdate=all&childforums=1 at the bottom
08:51 AM jepler: by default only recent (=1 year) of posts are searched, perhaps you overlooked changing this option
08:51 AM jepler: [because search on forum is slow, we limit search to recent posts by default]
08:51 AM jepler: anyway I'd recommend just using your favorite search engine with site: instead of using the forum's own search, it is set to be thoroughly indexed by search engines
08:53 AM probotix: i wouldn't disagree with that files are better, but some customers....
08:54 AM probotix: thanks
08:54 AM jepler: OK, I hope you found what you were interested in.
08:55 AM probotix: another question... I want to be able to display the G64 P parameter in axis, doesn't look like that possible with current python module
08:57 AM archivist: might want them to read http://hashmysql.org/wiki/Storing_files_in_the_database
09:34 AM probotix: any ideas on the G64 question?
09:37 AM archivist: no unless master has an extra pin in motion to connect to
09:57 AM jepler: no, that's not possible.
10:12 AM seb_kuzminsky: you could remap g64 to setp some pyvcp pins, then pass through to the real g64
11:30 AM jepler: wth is wrong with stepconf anyway -- all the text looks "greyed out"
01:06 PM tjtr33: could dgarrett's dynamic offset branch be used for trochoidal milling?
01:07 PM tjtr33: !seen dgarr
01:07 PM the_wench: last seen in #linuxcnc-devel 2017-10-15 16:25:26GMT 361:11:56 ago, saying 8190629 worked on my test -- thanks
01:13 PM seb_kuzminsky: tjtr33: i guess, but i think it'd be easier to do it directly in gcode
01:21 PM archivist: once you get used to ocode routines and maths in gcode, almost any shape :)
01:22 PM archivist: the thing to remember is put some scaling etc so you can reuse the code later
01:23 PM seb_kuzminsky: yeah
01:24 PM seb_kuzminsky: i feel like we must all have libraries of somewhat reusable g-code functions (or g-code generating functions written in some other language)
01:24 PM seb_kuzminsky: there have been attempts to make them more reusable, like ngcgui and features etc, but none have really caught on
01:25 PM archivist: I started out with a gear generator in php but soon moved to gcode with constants
01:25 PM seb_kuzminsky: i started out with g-code but switched to python
01:25 PM archivist: ew
01:25 PM seb_kuzminsky: here's my old g-code library: https://github.com/sebkuzminsky/lib-gcode
01:26 PM seb_kuzminsky: what finally killed native g-code for me was the lack of a way to share per-project constants between g-code files easily
01:26 PM archivist: I end up with commented gcode http://www.archivist.info/cnc/standard_clock_n_teeth.ngc
01:26 PM seb_kuzminsky: nice
01:33 PM archivist: hehe the old php is still up http://www.archivist.info/gear/
08:00 PM dgarr: tjtr33: i don't see that external offsets are a particular benefit to trochoidal milling as gcode suffices.
08:00 PM dgarr: The work by Bertho Stultiens on the gcmc frontend for making gcode includes a trochoidal milling example.
08:01 PM dgarr: Ngcgui supports entry boxes for settings to gcmc and includes sim examples (with his trochoidal milling) in the directory configs/sim/axis/ngcgui.
08:01 PM dgarr: The gcmc program must be installed separately and the executable (gcmc) must be in the user PATH environment.
08:01 PM dgarr: Instructions for getting/installing gcmc are at http://www.vagrearg.org/content/gcmc
08:16 PM dgarr: Instructions for using gcmc files with ngcgui (& pyngcgui) at http://linuxcnc.org/docs/2.7/html/gui/ngcgui.html#_gcode_meta_compiler_gcmc_file_requirements
10:51 PM tjtr33: dgarr, attach sine to x and cosine to Y. that might get circular orbital motion along G17 motions.
