Code:

net pendant:is-idle  => not.1.in

solved the problem!
Thank you!

For reference:

A method to analyze or debug a configuration that uses the xhc-hb04.tcl script
_and_ additional custom hal files is to insert an inifile line to show the signal
connections made by the script:

Example:

Code:

[HAL]
HALFILE   = primary_hal_file_1
...
HALFILE   = primary_hal_file_n
HALFILE   = LIB:xhc-hb04.tcl
HALCMD  = show sig pendant:    # <--- add this line
HALFILE   = custom_hal_file_1
...
HALFILE  = custom_hal_file_n

Start linuxcnc in a terminal using the path to the inifile
(if using run-in-place, source the rip-environment script first):

Code:

$ linuxcnc path_to_inifile.ini

An example printout for a simulator inifile adapted to use the
modification above (HALCMD = show sig pendant: ) will show all
the connections made by the script:

Code:

LinuxCNC 2.7 with MPG HB04 and i have a problem (or it is how it should be?).

# mpg_accels: provision for reduced acceleration for mpg jogging
mpg_accels = 50 50 500 600

This values have influence on my all settings.
Cant go to home, just crash my machine. Cant fast jog on keyboard, it is slow like should by but only when i use my mpg pendant...

Edit: Ok. I get it. MPG must be turned off before keyboard jog.

Not sure I understand any of your posting -- probably because of language
translation, nonetheless, the following investigation may be relevant
as it shows unexpected behavior when the pendant goes to sleep.

Current 2.7 (at commit 760a7f2) behavior for pendant:

When using LIB:xhc-hb04.tcl (with the axis gui) and using:

Code:

[XHC_HB04_CONFIG]mpg_accels = val1 val2 val3 val4

the jogging accelerations are set to the altered values (val1,val2,...)
when using the pendant jog wheel _AND_ when using the keyboard arrow keys in
manual mode.

When the pendant rotary switch is in the Off position, unaltered accelerations
are used for keyboard jogging. (So the jogging accels will be higher with the
pendant rotary in the off position).

However, the pendant goes to sleep if no buttons are touched for some number of
seconds (xhc.hb04.sleeping is set to 1). (It is unclear to me what conditions
are prerequisites for the pendant to go to sleep but it is detected by the
driver). When a pendant sleep occurs, the xhc-hb04.jog.enable-off is also set
to 1 and keyboard jogging reverts to unaltered accelerations independent of
any pendant rotary switch position.

So the pendant going to sleep causes unexpected behavior of the
accelerations used for keyboard jogging.

I have made a patch so that keyboard jogging (axis gui) honors the mpg_accels
whenever halui.is_manual is true. With this patch, the pendant going to sleep
will not change keyboard jogging acceleration -- the altered accel values
will be used whenever halui.is_manual is true.

The patch is in a test branch:
git.linuxcnc.org/gitweb?p=linuxcnc.git;a...45a5dd745e4e69c134cd

For interest, you can observe the behavior of the relevant hal pins
using halshow from a terminal while making tests with the pendant:

Code:

$ halshow px.halshow

where the file px.halshow is (example for x axis only):

Code:

$ cat px.halshow
pin+ini.0.max_acceleration pin+halui.mode.is-manual pin+xhc-hb04.jog.enable-off pin+xhc-hb04.jog.enable-x pin+xhc-hb04.sleeping

I recently migrated from Ubuntu 10.04/Linuxcnc2.7pre to Wheezy/Linuxcnc2.7.0 using the LiveCD. While my machine operation works as before, I'm having trouble with my xhc pendant. I am trying to follow the guidance given in the README file in the xhc-hb04 sim folder. When I run Linuxcnc, I get the following Debug info:

Is the monitor script not included in the LiveCD distribution? If not, how do I get it?

The error message posted seems to indicate that you
specified monitor-xhc-hb04.tcl as a [HAL]HALFILE= but it
is not a HALFILE, it is specified using APPLICATIONS]APP=

README excerpt:

Code:

A application named monitor-xhc-hb04 is included to monitor disconnects and
reconnects of the pendant.  This script runs in the background and will pop up
a message when the pendant is disconnected or reconnected.  Usage is optional;
if used it is specified with ini file entry:

  [APPLICATIONS]APP = monitor-xhc-hb04

The file is named monitor-xhc-hb04 (not monitor-xhc-hb04.tcl though
it is a tcl script) and it is located in /usr/bin and hence
in the standard PATH

Example query of a package install (uspace in this caae):

Code:

$ dpkg -L linuxcnc-uspace | grep monitor
/usr/bin/monitor-xhc-hb04

$ ls -l /usr/bin/monitor-xhc-hb04
-rwxr-xr-x 1 root root 4396 Sep 10 21:29 /usr/bin/monitor-xhc-hb04

Running one of the supplied simulator configs and studying
the ini file may be helpful
