Guidance for remapping of a M-command

Hello everybody,
I would like to ask, whether anybody can provide me with a small step-by-step guide to remap a M-command?
I had already a look on the document "extending EMC", but I'm missing some sort of a "red line" in this document.
Can anybody tell me how to start with the remap of an M-command?

Thank you for your help!

Hi

Everything is in www.linuxcnc.org/docs/devel/html/remap/structure.html and referenced in various posts on this forum

Don't know what you mean by red line

The place to start is to download the master (2.6~prexxxxx), build it as a RIP system and read and follow the examples in there.

Of course you don't need to remap M codes if all you want to do is implement something new, rather than change the way an existing M code works

All you have to do is write one www.linuxcnc.org/docs/html/gcode/m-code....d_sec_m100_to_m199_a

lugr,

a complete remapping example with ini configuration and the matching NGC procedure can be found here:

3.3.1. Example for named parameter passing to NGC procedures

which is in this section: www.linuxcnc.org/docs/devel/html/remap/s..._argspec_parameter_a

I _think_ you can remap in a pre-packaged and installed "Master" version from the buildbot, and that's rather easier.

Hi all,
Thank you for your quick responses. I've access to the GIT-server and I've already downloaded the files from there.
Do I just have to make some changes in the [PYTHON]-section in the xxx.ini-file according to the example from mhaberler or do I have to install something else?
regards

Hi lugr

If you are just starting I'd really recommend you install the buildbot master package instead of building yourself, see buildbot.linuxcnc.org/

Just try the example exactly as it is in the manual - it doesnt say anything about [PYTHON] and that is because that example does not need it.

Also explore the canned examples under configs/sim/remap .

hello michael,

I'm a collegue from lugr and try to install the buildbot master package.
in the description it is reffered to a path
/etc/apt/sources.list.d/linuxcnc-buildbot.list.
But the last argument "linuxcnc-buildbot.list" is not existing on my machine. how do I get the two lines
(deb buildbot.linuxcnc.org/ lucid v2.5_branch-sim
deb-src buildbot.linuxcnc.org/ lucid v2.5_branch-sim)
to that list?
Is linuxcnc-buildbot.list just a textfile which contains the two lines or what exactly do I have to do?

Thanks,
Thomas

Thomas,

this is a generic linux question and you will get better support on say ubuntu forums

that said: please read 'man sources.list' - yes it is a text file, and yes you have to add it

you do NOT want these lines, you are trying to install master, not 2.5:

(deb buildbot.linuxcnc.org/ lucid v2.5_branch-sim
deb-src buildbot.linuxcnc.org/ lucid v2.5_branch-sim)

you want these, assuming you want a simulator build:

deb buildbot.linuxcnc.org/ lucid master-sim
deb-src buildbot.linuxcnc.org/ lucid master-sim

I could manage it to get the master-sim data. But when I start one of the sample configurations under the remap section, linuxcnc aborts with the following error message
