You said in your original email that you couldn't connect the scale feedback to axis.n.joint-pos-fb - have you actually tried doing that?
The motion controller copies feedback to command while in the machine off state. The stepgen also updates its internal command position while it is disabled (which it should be in machine off). The motion controller shouldn't do anything when it's enabled (it might, and that would be a valid bug), and it should only apply screw correction when it starts moving, since it doesn't know any direction until then. Of course, this will be a problem if the magnitude of screw compensation is larger than your following error setting. - Steve ------------------------------------------------------------------------------ This SF.net email is sponsored by Make an app they can't live without Enter the BlackBerry Developer Challenge http://p.sf.net/sfu/RIM-dev2dev _______________________________________________ Emc-developers mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-developers
