5I25 7I77 PNC Config Problems

Hello all, before I start I just want to say thanks ahead of time for the support that this community gives to the open source CNC machinist and for any help I recieve. Also, if there is a post on this forum that has already addressed my problem, please lead me to it. I do not want to waste any of your time on questions that have already been asked.

So a little background, I am working on this 5i25/7i77 for a friend that lives 30 minutes from myself so i do not have a machine connected to this setup. I am only trying to get the 7i77 communicating and a configuration of linuxCNC running so that when i take the setup to my friends house, we can troubleshoot and tune on the machine without having to worry about the most basic stuff.

So here is what i have done so far.
1) Installed LinuxCNC
2) Installed 5i25 Card
3) Used mesaflash to load and verify 5i25_7i77x2.bit
4) Used bogie6040's shell script to load 5i25 files for pncconfig
4) Connected 7i77 and set jumper on 5i25 to supply power to 7i77
5) Connected 12V to field power on 7i77

Now when i run PNC Config i get the following error when clicking on Open Loop Test in the X Axis Motor/Encoder Configuration.

Traceback (most recent call last):
File "/usr/bin/pncconf", line 9106, in on_enableamp_toggled
self.update_axis_params()
File "/usr/bin/pncconf", line 9076, in update_axis_params
halrun.flush()
IOError: [Errno 32] Broken pipe

Thanks again for the help.

what version of linuxcnc arw you using? you really want the latest version.
try this:
open a terminal annd start pncconf (pncconf <return>)
now do an open loop test and there should be an error message in the terminal, when you get the broken pipe error.

Post that error.

When I load a sample configuration it says I am running 2.5.0. Is there a better way to check the version?

Error below

loadrt scope_rt failed

at first glance this looks like a pncconf bug:

<stdin>:12: Pin 'hm2_5i25.0.7i77.0.1..analogena' does not exist

The pin name should be hm2_5i25.0.7i77.0.1.analogena

So as cmorely said, updating pncconf is reccomended

updated through Synaptic Package Manager and now it works great. Thanks for the help.
