installing MPG2 handwheel on 3-axis mill

Hi -
Using LinuxCNC (2.5.4) with a Motenc-Lite PCI interface card on K2CNC "iron" I have been having good luck running long surfacing programs. Thanks to the LinuxCNC community for helping me get this far.
Now I'm trying to make setup a little easier by installing a handwheel.
For that purpose, I bought an MPG2 pendant and C22 interface card from CNC4PC. The hardware is installed, on the existing parallel port on my controller PC.
I started with the sample jog.hal file from Linux CNC linuxcnc.org/docs/2.5/html/examples/mpg.html and edited it to change all the parport.1.xxx's to parport.0.xxx because I'm figuring I can use the existing parallel port on the PC instead of a second one. The scenario envisioned for the jog.hal file is that a PCI card for a second parallel port will be used. In my case it's not necessary.
I added the edited jog.hal file to motenc.ini.

Fire 'er up and get alotta errors:

Can not find -sec MOT -var MOT -num 1
Can not find -sec IO -var IO -num 1
Can not find -sec LINUXCNC var NML_FILE -num 1
Can not find -sec EMC -var NML_FILE -num 1
jog.hal:35 'parport.0.pin-09-in' does not exist.

Any guidance is appreciated.

Hi -
I should have thought of this sooner ... I'm trying the incremental approach. I shortened my jog.hal file to two lines

loadrt hal_parport cfg="cc00"
addf parport.0.read servo-thread 1

... and that doesn't bomb! !! Wonderful! My feeling is: if you can get one thing to work, you can get other things to work.
Now I'm iterating through, adding a block of lines from the full-length jog.hal file that doesn't work to the shortened file that does not bomb.
I was getting so many errors in the beginning it didn't occur to me that the incremental approach might work. I thought I was doing something completely off the wall wrong.
Also, in the Utility HAL Meter, I'm seeing parport inputs ... so that's a good sign.
Thnx.

Using the incremental approach, I have found that LinuxCNC bombs (won't start; puts up error window) at this line:

net mpg-a encoder.0.phase-A <= parport.0.pin-02-in

... amongst other things, it says parport.0.pin-02-in does not exist. It does NOT say no parport input pins exist, because it accepts the line

net scale2 mux4.0.sel1 <= parport.0.pin-10-in

... just thinking out loud here. Do I remember that parallel ports -at least some of the pins- are bidirectional? Is there maybe a configuration setting other than "cc00" I should be using?
Thnx.

Hi -
Maybe this sample jog.hal file is giving me grief because I'm using the built-in parallel port on the computer ... maybe the built-in parallel port is being configured somewhere else in the O.S. and LinuxCNC is having trouble applying its own configuration ...
... still thinking out loud

With the change to cfg="0x378 in" LinuxCNC starts with the jog.hal file entire --pretty much the same as the sample file-- in place. There are no errors. On the other hand, the handwheel doesn't work at all. I'm beginning to suspect I missed something in the hardware install. At the bottom of the CNC4PC C22 interface card there are (5) terminal blocks, two for power and ground and (3) others for an estop circuit. Does anyone know if the estop terminals needs to be jumpered for the card to work?

Thanks.

When I power up the computer (or when I plug in the 5V and ground to the card), I hear a click from the relay on the card. I'm assuming the click is the relay pulling in (enabling) and that the card is set up to be enabled by default ... but I don't know. I couldn't figure out the C22 manual.
