Re: [Emc-users] EMC Fest 2008
Hi Aram, RS-274NGC as far as I can tell just doesn't provide for special functions. It does provide G01, G02, G03. Anything else is programmed by using that facility and programming externally. A few manufacturers have provided splines specially coded within their version of the interpreter ( Okuma comes to mind). More might do so if there were an universally agreed upon standard to representing the splines. To get around this most people with special needs write programs in their favorite language that represent the desired function in G code usually as small straight line segments or as short G02 or G03 segments to interpolate the function to the desired accuracy. This is also true of most of the CAD programs; they output small segments to represent contours, etc. The developers of EMC2 have worked on making the short segment stuff work well and that is within the limits of the present interpreter. So my suggestion is to grab your favorite programming language and go to work. Check Jon Elson's page for an example of hole making. I occasionally write programs to represent contours that are curved in two dimensions. Not too difficult to do. You just have to pay attention to details. A little geometry/trig and a good loop can do wonders.

[Emc-users] Tnx
Hi all, Just wanted to express my thanks to all the developers and others that have helped with the latest release of emc. I started at about 11:00 am this morning to update my 2.0.0 to the latest release. Installed Live off the CD then did the updates (which took about 1.5 hours). I swear everyone else wanted them at the same time because my usually decent cable went as low as 35 Kb/sec. I had a few issues with changed nomenclature in hal related to setting the spindle speed and homing on index. Ray Henry and people on IRC, mainly jepler got me set straight. Home on index now works for the stg card ( I think thanks there go to alex). By 4:00 pm everything was working. Many thanks to all who spend time working on emc in various capacities. I will do some testing in the next few days of things that didn't work too well with 2.0.0 and see if I don't get improvements. :-) See most of you, I hope, at fest.

[Emc-users] having to reload fpga config on m5i20 on every bootup?
Hi all, I'm using an m5i20 card with the hostmot5_4eh.bit configuration that allows PWM at 50 kHz. I have to reload the fpga configuration after each bootup of the machine with 'sudo m5i20cfg hostmot5_4eh.bit 0' In my HAL files I use the m5i20 driver without loading the default (wrong, in my case) fpga config: loadrt hal_m5i20 loadFpga=0 dacRate=1 (the driver assumes the PWM clock is 33MHz, but with the modified config it's actually 100MHz, so I config it to 16.7 kHz and get 3*16.7kHz=50kHz PWM output) should I have to do this m5i20cfg command every time I run emc or should the fpga config stick once it's loaded?

Regular HAL modules don't have any dependencies on each other. You can load them in any order, then once all are loaded you connect the pins together with signals. The kinematics code isn't a regular HAL component - it doesn't connect with pins, instead it uses function calls. We made it look like a HAL component so it could be loaded and used like one without having to recompile when you change kinematics. But there is a dependency between motmod and kins and they need to be loaded in the right order.

Re: [Emc-users] Manually loading motmod
Alex, John, Ok, it is obvious now. The missing symbols were kinematicsType, kinematicsInverse, and kinematicsForward, which all are defined on the subsequent line when exported with halcmd save. Specifically: loadrt trivkins Thus one can't do a halcmd save and then load the saved text with halcmd source, without checking the ordering, although some basic ordering is performed by the way it groups things into sections. Thanks, Eric You can check dmesg for the symbol missing.. the source for motmod is in emc2/src/emc/motion/*.c|h It gets built from a couple of files.. Anyways, if it works by running emc2 then the module is fine, and you're missing something (dmesg will shed lights there) - This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.

Re: [Emc-users] Buying used CNC machine - what to look for??
Dave, I live in Lenexa Kansas a suburb of Kansas City. I hopped to go to the EMC CNC workshop in IL however around that time I have a prior engagement with my wife. If I would go she would kill me and the machining hobby would be out the window. I might go next year. Is there anyone else in KC using EMC?

If you look in dmesg it will probably tell you what symbol is undefined. At the moment I don't know what might be missing, the symbol name would be a clue. Regarding the source for motmod - you are right there is no single file motmod.c. The motion module is the result of linking together several C files. Most are in src/emc/motion, although a few get pulled in from elsewhere like src/emc/kinematics. Ah, found the relevant chunk of the main Makefile: obj-$(CONFIG_MOTMOD) += motmod.o motmod-objs := emc/kinematics/cubic.o motmod-objs += emc/kinematics/tc.o motmod-objs += emc/kinematics/tp.o motmod-objs += emc/motion/motion.o motmod-objs += emc/motion/command.o motmod-objs += emc/motion/control.o motmod-objs += emc/motion/homing.o motmod-objs += emc/motion/emcmotglb.o motmod-objs += emc/motion/emcmotutil.o motmod-objs += libnml/posemath/_posemath.o motmod-objs += libnml/posemath/sincos.o $(MATHSTUB) Regards, John Kasunich - This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.

[Emc-users] Manually loading motmod
Hi all, I get the following error when trying to manually do a loadrt of motmod: Insmod: error inserting /usr/realtime-2.6.24.16-rtai/modules/emc2/motmod.ko:-1 unknown symbol in module. This is the error when using ubuntu 8.04, but I get essentially the same error under 6.06. It can be easily reproduced by doing the following: Run EMC with the tkemc sim configuration, then save it to a file, for example: halcmd save > tkemc.hal Shut down EMC. Start the realtime, i.e.: realtime start Reload the configuration, such as: halcmd source tkemc.hal Which will result in the above error, although everything else seems to be processed correctly. Manually typing in: halcmd loadrt motmod base_period_nsec=100 servo_period_nsec=100 traj_period_nsec=1000 key=111 num_joints=3 Results in the same error. I tried to find the source code for motmod.ko, but I was unable to locate something like motmod.c. There were a couple of similar files, but don't appear to be the source for motmod.ko. I haven't really tried grepping for it yet. Anyway, does anyone have some insight on the cause of this error?
