Always refer to documentation and/or 'halcmd show' before typing pin and
parameter name
You configure a probe just like almost everything else in emc: add the
right lines to a .hal file. In this case, you will be writing a line to
connect a signal to the pin "motion.probe-input". For example, if the
probe input is on parport pin 26*, you could write

When using stepconf, the BASE_PERIOD is chosen for you. If the required

hardware) has to control when the feedback position is

geographically separated system I could access:
$ traceroute -f15 cvs.linuxcnc.org

I've had a tcpdump running on 206.222.212.218 (bald.unpythonic.net) which
captured Paul's traceroute packets in and ICMP Unreachable replies back out.
These are the packets that traceroute expects to be generated when its trace
actually reaches the destination machine.
So the packets are reaching
I agree that what you describe would be great, and really lift AXIS up
to a whole new level when it comes to previewing gcode for >3 axis
machines. One stumbling block is that there are a lot of different
possible machines (maybe as many as 120 for machines up to 5 axes; I

When you set pluto-servo.pwm.#.pwmdir TRUE, the output should be what you
call "sign-magnitude":

Jon,
What *should* the driving signals look like at the input of your
