Hi all,
still a linuxcnc-newbie, I'd like to ask for a simple way to monitor the various limit switches (primarily for function, polarity) and also the actual signals (enab le, direction etc.) delivered from and to the parallel port at least during setup - as linuxcnc sees them.
I've seen some pyVCP solutions but can't figure out yet how to quickly add them to my installation - I'm a lifelong new-to-linux-user
My vision of that is something like in the Mach3 setup or like in Win-PCNC. Is there a simple solution that I just did not discover yet?
A pointer to a beginner's tutorial or article where I can start would be wunderful already at this time. Is it maybe even contained, but hidden, in stepconf already (to make it on topic here... ) ?
My first installation aims at a proxxon MF70 with a chinese TB6560 3 axis controller board. Yes,I know, not the top of the cream, the UHU driven servo motors for the next machine are here already, but... First steps first.
Regards, thanks,
Chattermark.

I don't think that LinuxCNC is running at all during a Stepconf session. (I can't test at the moment, I am nowhere near my LinuxCNC machines).
It must set up a temporary, minimal, LinuxCNC for the axis test.
To find out, open a terminal window when Stepconf is running and typeIf you see a list of HAL pins, then LinuxCNC is at least partially active.
If that is the case, then you can probably open an interactive HAL session and open a halscope (or several) to monitor individual pins.
As I said, I don't know if this will work

Can I start it from within the stepconf wizard, or do I hafve to do that from within the main program?

halcmd -kf
