So, knock on wood, I have my W (motorized knee) axis working, sans limit and home switches. It will be 100% done once I get the switches wired.
I did it, so that I can easily switch between long tools like big drill bits in Morse adaptors, to short tools like small end mills, without losing offsets or breaking up a program in pieces. The question is, what is the "proper" way to use it. My own thinking is that I should define a tool change position as Z=0 and W=<highest possible value>. This way, for any tool change, the mill opens up its full "envelope" completely. Z would be at its highest and W at its highest too (giving the lowest position of the knee). The "mouth" of the milling machine is opened at its highest. This way, any tool change can accommodate any sized tool, and the mill would not crush long tools under any circumstances. Also, every tool should have a W offset defined (and not Z offset), so that after a tool change, saying G0 W0 would adjust the knee position in accordance with the length of the tool. Is that the right way to think about it? thanks! i who is new to everything ------------------------------------------------------------------------------ What You Don't Know About Data Connectivity CAN Hurt You This paper provides an overview of data connectivity, details its effect on application quality, and explores various alternative solutions. http://p.sf.net/sfu/progress-d2d _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
