Thank you Andy. That took care of it. Don't know what I would do without all the help on here!

sudo: comp: command not found


We changed the name of "comp" to "halcompile"

The reason for this is something that you might have seen, when you try to run "comp" and it isn't installed there is a helpful suggestion to install some mail pacage or other. If you do that, then you will never get LinuxCNC "comp" to work. Even without that, having a HAL component called comp and a compiler called comp was confusing (sudo comp --install comp.comp.....)

So, from now on you need to use sudo halcompile..... Everything else stays the same.

2.7.0-pre7 And THCUD Module Problem

Category: Installing LinuxCNC

Hello,

I have been running a plasma table using the thcud setup. I recently installed the latest Debian Wheezy LinuxCNC 2.6 livedvd. All went well except first running LinuxCNC using the thcud config gave the error:

8postgui.hal:3: Pin 'thcud.current-offset' does not exist


So, I then ran the command:

sudo comp --install thcud.comp

and that took care of the error as I was able to run the table.

Yesterday, I upgraded this setup to LinuxCNC 2.7.0-pre7 using the instructions found here:

linuxcnc.org/docs/2.7/html/getting-start...e_to_the_new_version

After this upgrade went well, running the thcud setup gave the same error as before, so I went to install the thcud module, but got the error:

sudo: comp: command not found

I made sure I had the latest linuxcnc-dev. What did I do wrong? Any direction-pointing appreciated. Thank you.

I don't know what a signals and plasma screen is but after some searching I assume your following this wiki page?

wiki.linuxcnc.org/cgi-bin/wiki.pl?Gmoccapy_plasma

Then you need to contact Mariusl about his screen.

Ok,

i inserted "addf thcud servo-thread" in my HAL
No error during start up, but my signals and plasma panel is away! :-(
I know that effect.
This is my "Signals.HAL":
# Hook up signal pins connecting

# Out pin
#net MoveDown      => signals.led_MoveDown
#net MoveUp        => signals.led_MoveUp
#net FloatSwitch   => signals.led_FloatSwitch
#net ArcOK         => signals.led_ArcOK
#net TorchOn       => signals.led_TorchOn
#net HeightLock    => signals.led_HeightLock
If i remove one # i have the same effect.

That means don't change the base thread to floating point as Todd suggested. You can't just guess what to put in the hal file it only supports a few commands like net, addf, sets, setp and they have specific format.

If the thcud component uses FP (Floating Point) then add it to the servo thread just like other functions have been added to the servo thread. It's my fault I assumed the thcud was not using FP so I told you wrong.
loadrt thcud
addf thcud servo-thread

This should get the component up and running then you have to use the net command to connect the pins.

I'm confused...

what means:
"leave the base-thread alone"?

addf thcud base-thread (=error)
thcud base-thread (=error unknown command)
base-thread (=error unknown command)

and which part is the servo thread?
iIn my HAL are things like:
"addf stepgen.capture-position servo-thread"
Is that the servo-thread?
Should i insert "addf thcud base-thread" behind that part or "base_thread_fp=1 "

Just leave the base-thread alone and add the function to the servo-thread.

I think i'm to stupid for that.
Since two weeks the machine is ready and has to run.
It is cheaper if a specialist flies from USA and adjusts the parameters.
And i understand nothing.

I have searched in all files.
"base_thread_fp=0" doesn't exist

So i have added this
"base_thread_fp=1" in the .hal
- error: unknown command

with the addf in front:
- error: addf needs 2 args

It means that it needs to be in a floating point thread (such as the servo-thread), and the base-thread you have it in is non-floating point. it is possible to configure the base thread to support a floating point.

see: linuxcnc.org/docs/html/man/man9/motion.9.html

You will need to find base_thread_fp=0 and change it to base_thread_fp=1 (or add it if it does not exist.)

Ah, ok! :-)

I have the same HalShow than in axis.
If i select "functions", there is a lot of stuff and "thcud".
And selected:
owner 12
CodeAddr f8ff0000
Argf8ff8
FP yes
users 0
name thcud


after i inserted in my hal:
addf thcud base-thread
i get the error message:
error ; function  'thcud' needs FP

What does that mean? FP is YES

I know the link to the manpage.
It's only a short description.
Are there any further informations?

If i insert in the .hal
loadrt thcud
and
thc.torch-up <= paraport.0.pin-15-in

Error message: thc.torch-up


The man page is all the documentation for the thcud component and is quite elaborate compared to most man pages.

Lets start at the top:
First you have to load the component in your hal file with:
loadrt thcud

Next in Axis (I don't know about other GUI's) run Show Hal Configuration and see what the name of the thcud function is. Then you have to 'add' the thcud component to a thread so it will actual do something with:
addf thcud base-thread

Next looking in Show Hal Configuration Pins find the exact name of the pins you wish to connect to and using the net command and a signal name connect them.
net torch-up thcud.torch-up <= paraport.0.pin-12-in

Please read about the net command here:

Error message: thc.torch-up
Update:
This sentence:
thc.torch-up <= paraport.0.pin-12-in thc.torch-down <= paraport.0.pin-13-in motion.spindle-on => parport.0.pin-16-out (start the arc) thc.arc-ok <= motion.digital-in-00 <= parport.0.pin-15-in
from manpage means:
net thc.torch-up <= parport.0.pin-15-in
net thc.torch-down <= parport.0.pin-10-in
net thc.requested-vel <= motion.requested-vel
net thc.current-vel <= motion.current-vel

Next error: the name is parport, NOT paraport

And so on. At the moment it works, but always without Up/Down


typo should be
parport.0.pin-12-in thc.torch-down <= parport.0.pin-13-in

@BigJohnT
I googled for hours and hours.
thcud.comp is not downloadable? What is wrong?


The thcud component is part of LinuxCNC you merely have to load it in your hal file.

Again the link to thcud man page.

www.linuxcnc.org/docs/2.7/html/man/man9/thcud.9.html
