I finally got it working! Thanks Eric. Emcrsh is really quite neat. A couple of observations though - 1. I checked the source code for emcrsh and it hard codes the relative path "../../nc_files". I think this doesn't make sense since it precludes absolute paths and creates confusion by implementing relative paths and hardcoded directories. I would either leave the path off or allow it to be a parameter to emcrsh. Also the path is different from the path specified in the .hal file. 2. When a file is finally opened the telnet session gets an ACK but the Axis screen doesn't refresh. The filename on the title bar changes but the code and the image in the path window doesn't update. This certainly doesn't give you the warm fuzzy feeling that the right thing is going to happen when you hit run! 3. Perhaps it is because my print out of the help text split task_plan_init onto two pages but I wouldn't have guessed that I needed to set task_plan_init before opening a file. I think this may have been the reason that my previous attempts at moving nc_files around and trying to open my test didn't work. Since I'm not sure how you can open a file without calling task_plan_init maybe open should call it automatically. 4. Occasionally when emc initializes it doesn't allow connections through port 5007. I'm not sure how to reproduce this but it happens about 1 in 5 times.
Thanks again for everything - Mike -----Original Message----- From: Eric H.

Michael, Sorry, I was responding from memory and gave you the wrong path. It is relative to the nc_files folder ($HOME/emc2/nc_files by default). At any rate do the following: In your hal file add the line: loadusr emcrsh IOW, with no parameters. To get it going we will use all of the defaults. For testing purposes you can use the sim tkemc configuration. Just add the above to core_sim.hal in the configs/sim folder. Then telnet in and issue the following commands: hello EMC client 1.0 set echo off set verbose on set enable EMCTOO set task_plan_init set mode auto set open examples/3D_Chips.ngc This should load the 3D_Chips.ngc example program. I turned verbose on so that you get more informative error messages. The remainder is the sequence I use when loading a new program. Regards, Eric Eric, Thanks for the response but I still can't convince the "set open test.ngc" command to work. I've moved the nc_files directory all over the machine to no avail. The relative directory error message, of course, is less than helpful. I think the trick will be to get the -ini method working. If I could explicitly specify the path then debugging would be easier. Has anyone gotten the "set open" method working on Ubuntu? If so, please shed some light. Rafael, I think your points are valid but they don't simply apply to linux novices. Relative paths without a well documented root are difficult to work with and confusing even to folks like me with 30 years of software experience! ------------------------------------------------------------------------ ------ Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.
