There is allot of documentation available for EMC, the problem is in knowing where or how to look for it. Of course, you need to read and re-read the manuals. I then usually go to linuxcnc.org and do a keyword search using the box in the lower left hand corner. Be sure to check the LinuxCNC radio button. Then I check comments in the C code. The problem with C code is that there are usually many different versions and to the inexperienced, like me, its not obvious what's valid. Then, if I still haven't found an answer, I just guess and and see what happens. Unfortunately for you, your class situation may not allow you the time to get used to EMC. I too, would like to add some new G codes to EMC. A while back I started to trace where the codes where handled. I believe that the user interface (such as AXIS) feeds lines of code to the rs274 interpreter, where each line is parsed and then converted to NML (Neutral Machine Language) commands. Check out the code here: http://cvs.linuxcnc.org/lxr/source/src/emc/rs274ngc/ especially: http://cvs.linuxcnc.org/lxr/source/src/emc/rs274ngc/interp_convert.cc So, I guess you need to add an entry that recognizes your new code and then associate it with a list of NML commands. That's as far as I have gotten in this regard. > > Also, I am tuning my other AC servo motor that is much larger that I > brought to show. > It is SEM type of motor. ... snip I can't help much here. I just tried different settings until things worked reasonably well.
