LinuxCNC Pure Simulator in 10.04

wiki.linuxcnc.org/cgi-bin/wiki.pl?LinuxCNC_Pure_Simulator says it's very easy so it must be:)
But I'm clueless so maybe not for me.

wget www.linuxcnc.org/lucid/dists/lucid/linux...c-sim_2.5.1_i386.deb

Now I'm stuck.

Hi

I think you are getting caught between two stools and the emc2 re-branding.

If you actually want to run a pure simulator on 10.04 ( no reason to do so, the sim configs all work under the rt version ) you need to remove the rt version emc2
sudo dpkg -r emc2
then install as you previously tried.

The alternative might be to download the source and build the sim as a RIP (run in place) and it will not clash with existing system.

I use the 10.04 rt system on a computer with no parport in the house as a development machine, running all sorts of homebrew sim configs as well as the provided ones.
No real need for a sim package, if the rt one will run.

It is mostly people with such new hardware that only > 12.xx will run on it, that go for the sim only ( and maybe laptops)

ArcEye,
thanks, so are you saying that the sim is superfluous for software simulation?
I installed LinuxCNC per the live cd.
All I want to do is test and mess around with the software without having to have servos and encoders attached.
Obviously I don't expect input from non-existant hardware.

BJT,
thanks, isn't that just running through a G code routine?

I was more interested in having something that would simulate the machine using dummy I/Os.

I may be missing something here.

BJT,
thanks, better I do some serious study before trying to add stuff that may be redundant.

I was more interested in having something that would simulate the machine using dummy I/Os.

You can do whatever you want in a sim, except that you don't have the usual input.

In the past I have got around this by writing a component that simulated the hardware.

For instance, I was developing a toolchange component that worked an ATC on a lathe.

It obviously relied upon feedback from the ATC which it was not going to get, so I wrote another component that simulated the ATC and connected this to it.
This sent back a series of positional signals and 'tripped switches' as the real one would do and enabled me to test through a complete tool change cycle.

regards

ArcEye,
thanks, that is what I would expect I would need to do. If I can do this with LinuxCNC as installed then all I need to do is learn how to use it.
