You need to read read and read again. :) http://linuxcnc.org/docview/html/
You will want to do a latency test on the hardware (to make your hardware will decent realtime performance) http://www.linuxcnc.org/docview/html//config_stepconf.html#sec:Latency-Test That being said... You can test emc for performance by downloading the livecd here http://www.linuxcnc.org/content/view/21/4/lang,en/ and booting from it. It will not change anyting on your existing computer but will allow you to test emc2. There are a bunch of sim configs that will allow you to test gcode to see how it runs. (you might want to make a config though with your known max velocities and accelerations.) As far as how smooth it will run. Emc has a naive cam detector when using G64Px.xxx. This combines line segments that are within the Px.xxx tolerance. It really helps improve the speed of cutting. http://www.linuxcnc.org/docview/html//gcode_main.html#sub:G61,-G61.1,-G64: and http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?TrajectoryControl Give it a try. sam [email protected] wrote: > Hallo, > I new to EMC and before I start to work my self through the documentation > and try to get it running with my machine I’d like here your opinions: > > I’m looking for a solution to control a 4 axis CNC mill (3 axis router + > rotator axis).
