Thankyou both First, the LOW on pin 1 was 0v sorry to muddy the waters.
Second, I corrected the "-out-invert" problem now I get this Error message "Debug file information: Can not find -sec MOT -var MOT -num 1 Can not find -sec IO -var IO -num 1 Can not find -sec LINUXCNC -var NML_FILE -num 1 Can not find -sec EMC -var NML_FILE -num 1 BillsMill.hal:24: setp requires 2 arguments, 1 given 6953 PID TTY STAT TIME COMMAND" What does all this mean? Third, I have included the line net "Xhome parport.0.pin-10-in=> axis.0.home-sw-in axis.0.neg-lim-sw-in axis.0.pos-lim-sw-in" Is this OK? Stepper configuration article says this: "### Shared home switches all on one parallel port pin? ### that's ok, hook the same signal to all the axes, but be sure to ### set HOME_IS_SHARED and HOME_SEQUENCE in the ini file. See the ### user manual!" Is this necessary ? if so, where and what do I enter in my .ini? Hope I'm making sense Regards Bill PS Gene, Hows the back going, any news on the op.?
