Re: [Emc-users] NGC highlighting in Vim
Excellent! Thanks, Phil. I'd love your help with it, as well as anyone in here who uses Vim. The more of our eyes, the more glitches we'll iron out, and the more useful the syntax file will become. I'm not in the #emc too often, and usually only very late, but I'll look you up. Meanwhile, feel free to post anything you notice in reply to this thread, or if you'd like, you can always email me directly.

Thanks. c brauer The procedure depends on the file(s) you are adding - it will be different for realtime code vs. user space code, etc. In your case, I looked in src/emc/klnematics, and I didn't see tripod.c, although there is a tripodkins.c. Was tripod.c a typo, or am I looking in the wrong place? Assuming you meant tripodkins.c - look in the main makefile in the src/ directory - if you search for tripod you will find: obj-m += tripodkins.o tripodkins-objs := emc/kinematics/tripodkins.o and farther down in the file: ../rtlib/tripodkins$(MODULE_EXT): $(addprefix objects/rt,$(tripodkins-objs)) You'll need to duplicate both of those using the name of your new file.

I have been doing it on the Bridgeport with a Procunier tapping head, but that is such a long assembly it gets a bit wobbly. Rapidly reversing the big Bridgeport motor is going to be hard on things, and getting an encoder on the spindle looks difficult. I have this little minimill, and have to come up with the right fixturing for the workpiece, but its motor should be able to reverse a lot more easily, and I already have an encoder on it.

However, if you do prefer to integrate the new module with the emc source tree, you can do that too. For .comp files, just place the file in src/hal/components or src/hal/drivers as appropriate.

It's generally NOT a good idea to power logic and high brakes from the same supply. Actuating a brake can cause power surges that will adversely affect your logic.
