I have been proceeding with a number of retrofits I have come up with a couple of issues with a Brother T-217 Firstly the tool change process is handled entirely by moving the z axis there are a number of cams at the top end of travel that grasp the tool, release the drawbar etc. Moving into this Z range during operation would be catastrophic, the tool would impact the tool changer fingers destroying them.
I would like to limit travel into this region during normal program execution but relax this during tool change operation. Similar functionality is in place on many other controls for instance our Haas SL-20 has configurable exclusion zones for the tailstock. My thought for a hack would be to simple be able to change the values of pins holding the min_x, max_x etc of the axis. I saw there where ini.0.max_limit but this value doesnt seem to have any effect when changed at runtime. I was wondering what people would think about this? I would like to add some functionality to linuxcnc since i use it so much and a feature with an exclusion region would be possibly useful but I wouldnt want to add it if it wasnt something that would get rolled into the main branch since I dont really need that much functionality for this one application. -- -Roland ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ Emc-developers mailing list Emc-developers@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-developers
