Re: [Emc-users] Two machine configurations -> g-code check
Tomaz, Thanks for the video! A possible solution: Use a file naming suffix such as (.nc1), (.nc2). Create a terminal script to read the file and choose the proper configuration. Another possible solution: A switch on the rotary table to tell the control computer the table is in place. (or a toggle switch on the control panel) A terminal script sees the switch and chooses the proper configuration. Another possible solution: A rotary table switch. (or a toggle switch on the control panel) The (.ini) configuration file sees the switch and chooses which configuration section to read/omit to read. I am having a hard time seeing a problem to solve. If the rotary table is always connected then the machine will always run the program. I don't see a reason to have separate post processors. Having a command in the .nc file seems too late. The set up instructions should prescribe how the machine is set up. If not, the problem is not solvable at the time of running the .nc file. Just my two cents regards Stuart I am having a hard time understanding the desire/need.

OK, so this time I have tested it, and it did take a bit of work to make it
work.
Here is the actual Python code that is working for me
#! /usr/bin/python3
import linuxcnc
import sys
s = linuxcnc.stat()
c = linuxcnc.command()
s.poll()
inifile = linuxcnc.ini(s.ini_filename)
print(inifile.find("EMC", "MACHINE"))
if inifile.find("EMC", "MACHINE") != "MyCOnfig":
c.error_msg("This G-code is for a different config")
c.abort()
It might not work if /usr/bin/python3 isn't your Python version. I wanted
to use "#! /usr/bin/env python" but that wasn't working on my particular
machine.
First make sure that just typing ./M100 in the nc files directory works. It
will error-out, but should at least try to execute.
When that is working, then start LinuxCNC from the command line:
linuxcnc &
(The & means that you can carry on typing commands in the command line)
When LinuxCNC is loaded and homed then you can try to run the M100 from
the command-line again
./M100
And this time it should work, or at least not error.
Then you can try running M100 from the command prompt, and that will work
if LinuxCNC can find the file.
If this all works, then you can finally try running the M100 from G-code.

Re: [Emc-users] Two machine configurations -> g-code check
That is correct, I don't use "B" axis on head/head in case/config where workpiece is rotating so in this config B axis is used for that and head/heads "B" axis is in this case/config as A axis and used only for homing. In g-code A is not programed in any case. If machine is used as classic 5-axis (with kinematics), then head/head is B/C and rotary (for workpiece) is removed from machine but not disconnected and is configured as A just for homing (I don't like to disconnect/connect cables many times) Here short video in 5-axis "mode":https://youtu.be/g2MSzw1MhYU?feature=shared=42 > Tomaz, > I watched the video.

Re: [Emc-users] Two machine configurations -> g-code check
Tomaz, I watched the video. Even at .25 speed I could not see the axis movement of the head/head. I would like to see the head/head moving. Do you sometimes run with the A axis rotary table unhooked from the control?

Re: [Emc-users] Two machine configurations -> g-code check
Machine is 5-axis head-head, but now I have added rotary axis for workpiece turn which is also parallel to B axis, so in one configuration I use 5-axis knematics, for other I don't need to. Now I also have two post processors and I need to be careful to select the right one for the current job, and if I'm not, I need to prevent on machine that I run it on wrong configuration. Here you can see first tryout of added rotary axis, milling long speargun: https://youtu.be/Q-HBN2Rs0vE Configuration in my case is XYZABC as I need A in one or the other case to home "unused" axis. > How are the two machines configured? > Do you have XYZAB and XYZAC? ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
Re: [Emc-users] Two machine configurations -> g-code check
How are the two machines configured?
Do you have XYZAB and XYZAC?

How would you decide which config the G-code was for?
If you want to put an M-code in the G-code, and that is what determines
the target machine of the G-code, then maybe a custom M-code is the way, as
you suggest.
Something like M100 for one config, and M101 for the other.
file: M100
#! /usr/bin/env/ python
import linuxcnc
if inifile.find("EMC", "MACHINE") != "LinuxCNC-HAL-SIM-AXIS":
c = linuxcnc.command()
c.error_msg("This G-code is for a different config")
c.abort()
Make the file executable, put it in the nc_files directory, (or in the
SUBROUTINE_PATH) and it will abort running the G-code when it runs M100 if
the MACHINE entry in the active INI is not the specified string.
Probably. I haven't tested it :-)
