I have tried a very basic config just to get my motors to turn adn I keep getting errors. This is the error:

I have changed the y2 back to y but I get an error that says that signal is already assigned to a different pin or name.

Thoughts? Help?

This error message tells it all.
./my_LinuxCNC_machine.hal:147: Pin 'pid.y2.index-enable' does not exist

I would look in your hal file and check that your pids are named as you expect with loadrt and addf statements

So LINUXCNC finally opens without error but I cannot enable the machine (f2). I create a basic ini and hal and it lets me enable the machine but the motors do not turn when I try to jog them from the home screen.

I got the "no hostmot2" error in pncconf but I was able to turn the motors before I modified the hal and ini for the dual motors. I don't know if that matters since I could move the motors, ping the card, etc.

here is my current hal: (I am not sure that I have the # external input signals correctly assigned, I do not have anything connected to those pins yet)

Did you home the machine before trying to jog - I'm not sure if pncconf sets up joint jogging before homing.

Do you have an e-stop wired to mesa board ?
If yes, make the input for it inverted.
If no, ommit the line pertaining to e-stop in hal.

J Crowder, I sense your frustation, I have been there myself. Had some great help from RODW (and others), and am happy to share my working Mesa 7i96 gantry style XYYZ cnc config with you

My XYYZ config (all files including .hal and so on)


Part of the message is hidden for the guests. Please log in or register to see it.


Originally my machine used two standard parallel BOB's. I wanted something more modern so I bought a Mesa 7i96 card (more in and outputs for example for my new control panel) and started of with a new config made with BigJohn's excelent 7i96 tool. I merged the two configs and am very happy how everything works now. I use gmoccapy and a touchscreen right now, also a xhc-hb04 for remote control. Gmoccapy does automatic tool measuring with each tool-change (and moves the spindle to a convient location to change the router bit).
My configs are not optimized and could do with some clean up. But it works for now and I am happy. I am sure you could use some of the settings for your setup.

BigJohn's tool:
gnipsel.com/linuxcnc/7i96/index.html (much better then the pncconf that is supplied with LinuxCNC in my opinion.)

I turned off the "require homing " before movement option in pncconf before I modified the files.

I went back a created a very generic config and I can jog the motors from the Linuxcnc home page.

I have a lot to learn still. I am reading everything can but some of it is confusing because it is not my controller/ setup and it takes me down a path that does not work for me.

I do but I am sure it is not wired correctly. I really need to find some good schematics on how others have wired e-stop, limit switches, etc. I search the forums and get caught following some posts that don't really apply to my board/ setup. I will go in an omit all inputs since none of them are connected currently. Will let you know.
