Reading the docs: http://www.linuxcnc.org/docview/html//config_emc2hal.html It seems that emc-enable-in needs to be driven false to operate. I assume that your switches are true normally, and go false when activated. I bet that pressing both switches works as anticipated. I got the logic wrong. This is your current truth-table: in0 in1 out 0 0 0 0 1 1 1 0 1 1 1 1 Which means that the e-stop will only activate with both switches pressed. I think you need to swap the "or2" for an "and2" (or an extra "and2" if you already have one or more). in0 in1 out 0 0 0 0 1 0 1 0 0 1 1 1 -- atp ------------------------------------------------------------------------------ Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing. http://p.sf.net/sfu/novell-sfdev2dev _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
