firmware 5i25,7i85,8i20 brushless servo drive

Actually hardware wise the Fanuc serial encoders are simpler to use (just 4 wires and power no Halls no C1,C2,C4,C8)
But I dont know what type of Fanuc encoders you have

Did you try the ini/hal file set I posted? If it didn't load, can you post the error messages?

I don't know how to load it.

I clicked and dragged it to johns-linuxcnc-configs-hm2-servo.

I do not know what the next step is.

You need to unzip it and then select 5i25green from the linuxcnc config picker

one way to unzip is
open a terminal
cd ~/linuxcnc/configs/ johns-linuxcnc-configs-hm2-servo/

(assuming johns-linuxcnc-configs-hm2-servo is a directory)
and then type:

unzip green.zip

I get error in the terminal- unzip: cannot find or open green.zip


Previously I had un zipped with the graphical user interface before dragging it to hm2-servo , so I don't know if that was the problem.

The hal file that you sent me said something about making a symlink , so I cut - contrl+shift+v to put the command into a terminal and pressed enter.

It then said "the file exists" or something like that.

dont do any of the symlink stuff in the comments, thats just leftovers from the original source hal file

if you unzipped green.zip into

~/linuxcnc/configs/hostmot2/

(the ~ means your home directory)

You should have
5i25green.ini
and
hm2-servogreen.hal

in the ~/linuxcnc/configs/hostmot2/ directory

At this point you should be able to start the linuxcnc config
chooser and choose 5i25green as a config file option

I am making a little bit of progress- 5i25green tries to start but ends in error messages.
I hope I included enough information.


I don't see any lights on 5i25. I moved the w2 jumper up and now 7i85 cr1 lights up. I do not have 8i20 connected.

Yea , I had noticed that the format was different in the manual.

I removed num_sserials=4 from the ini file and replaced it with the entry that you gave me. (am I supposed to put numbers where the xxxx is?).

It made a difference in the error message.

Thanks a lot for your response.

So what is my next step?

I am not seeing a "wiring diagram" to connect between the 7i85 and the 8i20 servo drive.
