Ran the wizard, still no worky...5i25/7i77

OK next question: do you have 5V and field power on the 7I77?

(Yellow LEDs CR1 (5V) and CR3 (Field power) illuminated on top edge of 7I77)

I have cr1 but not cr3.

Ok I don't have a power supply hooked to field on the 7i77 yet . Do I need this to allow the 5i25 to be found?

You need the field power so all of the pins get made.
without field power on the pins that come directly from the 5i25 will be present.

But linuxcnc will find the 5i25 , it just may error if it tries to connect the missing pins.

If pncconf isn't showing the 5i25 in it's selection box, then either the XML files are missing or their permissions are wrong.
You should be using the latest version of linuxcnc as well (2.5.3)

Hello. I hooked up 12 volt field power. I have cr1 and cr3 on and cr16 on and two yellow lights on in the middle of the 7i77 that the text is so small I cant read them.

Tried pcconf again and it still doesn't show 5i25

In my Getting started manual it says V2.5, 2012-04-01

Having the 5i25 show up in PNCcong has _nothing_ to do with the 5i25.

It will show up even if you don't have a 5i25 connected.

Please check the permissions of the XML files.

I should add where the the files are located


look in /lib/firmware/hm2/5i25

There should be XML files in there.

please check the permissions of the 5i25 folder and the files.
right click, properties, permissions

owner , group , others what are the access (should be something like read only)

That 5i25 folder has a X over it and in permissions it shows owner- root , group- root and looks like no access

Probably root ownership is OK but you do need the xml files to be world readable

sudo chmod +r /lib/firmware/hm2/5i25/*.*

will do this

(be careful about the path, sudo chmod in the wrong place can cause a world of hurt)
