Hi
I have problem with paramsaver syntax. "safe tool change" . I would like the syntax and links to hal components. I need at the toolchange, write new tool to paramsavers. I would like to look into yours hal and ini.
I don't know how to use M68, with motion.analog-out-xx.

My hal:
# _DO NOT_ include your HAL commands here.
# Put custom HAL commands in custom_postgui.hal
# The commands in this file are run after the GUI loads

# **** Setup of spindle speed display using pyvcp -START ****

net spindle-vel-cmd-rpm-abs => pyvcp.spindle-speed

#prisavky s materialom
net appc halui.mdi-command-10 pyvcp.appc
net ap halui.mdi-command-12 pyvcp.ap
net am halui.mdi-command-13 pyvcp.am
net nul halui.mdi-command-14 pyvcp.nul


########################## FILE SAVER ###################################
#
loadusr -W paramsaver f=3 s=1 b=0 filename=memory_pins onstart=1 onexit=1

net material_in pyvcp.mat => paramsaver.invalueF-000
net material_out pyvcp.spinbox.0.param_pin <= paramsaver.outvalueF-000

net podlozka_in pyvcp.pris => paramsaver.invalueF-001
net podlozka_out pyvcp.spinbox.1.param_pin <= paramsaver.outvalueF-001

############################### Memory tool #########################################

net tool_number_in iocontrol.0.tool-number => paramsaver.invalueS-000
net tool_number_out ?????????????????? <= paramsaver.outvalueS-000

net writetrigger motion.digital-out-03 paramsaver.writetrigger
net readtrigger motion.digital-out-04 paramsaver.readtrigger

########################## FILE SAVER END ###################################

What problem do you have?

ie: What do you do, what happens, how is that different from what you expected to happen?

I have problem with paramsaver, his syntax. Not worked.
But now i have progress with the paramsaver.
This works:
In custom hal:
loadusr -W paramsaver f=3 s=0 b=0 filename=memory_pins onstart=1 onexit=0 (onexit=0 it has to be)

net tool_number_in motion.analog-out-04 => paramsaver.invalueF-002
net tool_number_out <= paramsaver.outvalueF-002

net writetrigger motion.digital-out-03 paramsaver.writetrigger
net readtrigger motion.digital-out-04 paramsaver.readtrigger


in INI:
MDI_COMMAND=M120 M61 Q[#<_hal[tool_number_out]>]
REMAP=G88.1 modalgroup=1 ngc=g881 (The program that is called on the last calibrated axis)

The program:
o<g881> sub
M61 q#<_hal[tool_number_out]>
o<g881> endsub [1]
m2

Thanks.

Hi
Problem with "paramsaver" in version 2.8.0

For version 2.7.14 in the terminal compile command "halcompile --install --userspace /home/hcnc/linuxcnc/paramsaver.c" looks like this:

Extract from the terminal:
root@H61M-C:/home/hcnc# halcompile --install --userspace /home/hcnc/linuxcnc/paramsaver.c
gcc -Os -g -I. -I/usr/realtime-3.4-9-rtai-686-pae/include -I. -I/usr/realtime-3.4-9-rtai-686-pae/include -I/usr/include/i386-linux-gnu -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=0 -fno-math-errno -funsafe-math-optimizations -fno-rounding-math -fno-signaling-nans -fcx-limited-range -mhard-float -DRTAI=3 -fno-fast-math -mieee-fp -fno-unsafe-math-optimizations -DRTAPI -D_GNU_SOURCE -Drealtime -D__MODULE__ -I/usr/include/linuxcnc -Wframe-larger-than=2560 -URTAPI -U__MODULE__ -DULAPI -Os  -o paramsaver /tmp/tmpgNP5a4/paramsaver.c -Wl,-rpath,/lib -L/lib -llinuxcnchal 
root@H61M-C:/home/hcnc#

Works OK on my config machine,
but for version 2.8.0 in the terminal compile command "halcompile --install --userspace /home/hcnc/linuxcnc/paramsaver.c" looks like this:
Extract from the terminal:
root@E8400:/home/hcnc# halcompile --compile --userspace /home/hcnc/linuxcnc/paramsaver.c
gcc -I/usr/include -I/usr/include/linuxcnc -URTAPI -U__MODULE__ -DULAPI -Os  -o paramsaver /tmp/tmpAzSwbK/paramsaver.c -Wl,-rpath,/lib -L/lib -llinuxcnchal 
root@E8400:/home/hcnc#
this no works. The paramsaver component was not created.

From the terminal LinuxCNC Errors:
File "/usr/bin/paramsaver", line 3
    paramsaver component
                       ^
SyntaxError: invalid syntax
pyvcp_options.hal:13: waitpid failed paramsaver paramsaver

I have already installed "build-essential" and "linuxcnc-dev"
Where is the problem? Please help.

Well for one you are using ROOT on a Linux box, and that is never a good idea, from security standpoint and from the issues that arise with software that is made to run as a normal user with limited privileges, access to files and folders, etc.

The second command only compiles the component it does not install it. You need to use the first command to install the component.

BOOM!!!!! I'm stupid. I didn't notice the difference written --install and --compile. Thanks.
It's already working.

I have been keeping this in my inbox to get back to.

Glad that I didn't need to.

But I will point out that you should probably have saved the file as "paramsaver.comp" and used halcompile --install paramsaver.comp

You don't say if you pre-processed to a C file, but I assume so. There is no need.

The .comp file has the keywords to declare that it is userspace.

Hi, I have a problem again. After a clean installation 2.8.1 i can't install paramsaver correctly.

From terminal>
hcnc@DH61SA:~$ sudo halcompile --install --userspace /home/hcnc/linuxcnc/paramsaver.c
gcc -I/usr/include -I/usr/include/linuxcnc -URTAPI -U__MODULE__ -DULAPI -Os  -o paramsaver /tmp/tmpbF1yoR/paramsaver.c -Wl,-rpath,/lib -L/lib -llinuxcnchal
Paramsaver is not in the machine configuration.

I did the installation:
BUSTER
sudo apt-get install build-essential
linuxcnc-uspace-dev
linuxcnc-uspace-dbgsym

EDIT: solved
