Yes, it should be possible, IF you have separate switches for positive and negative limit. Code is at http://git.linuxcnc.org/gitweb?p=linuxcnc.git;a=blob;f=src/emc/motion/control.c;h=ea47096f91a9e0b7dcf7c898ddae326b287721f3;hb=HEAD The limit switch HAL pins are read at line 448 Code at line

Wow - that is pretty.. Love the MPG's in the apron. Can't wait for a video showing them working! The K is a pain to get off of the over travel limits - but it has only happened once when I forgot to home and jogged it into the limit. The matsuura is even harder. You would have to remove

Should it be possible to jog off of a limit with an MPG? I have never managed to, and on my new lathe it takes a bit of dismantling to get to the screws to manually rotate the screw. Of course, when the machine is properly set up, this should never happen. -- atp "A motorcycle is a bicycle with
