simulation

I am usually working with milling machines, the simulation generally in axis is as a quick test, because it was already done in a Cam system. Last Friday I had the need to program a compensated trajectory on a very large lathe that assembled with linuxcnc, and I had to remove the piece to be able to test the program until I could make the compensated trajectory work well.

It is there that I realized that you cannot test programs on Linux with Axis. I had not noticed it before.

I usually program Fanuc-Fagor-Hass, etc. and I have always simulated the programs on foot. I never realized this in Linuxcnc

It occurs to me that I could save the state of linuxcnc before when I request the simulation mode, disconnect the outside world, and when I return to the execution mode to recover the state prior to the simulation request. as if it were a call to an interruption in microcontrollers.

It would be interesting to have this type of function.

Again, the first answer can do all you are asking for.

You tell me that the solution is to have two linuxcnc working in the same machine, one as a simulator and another functional?

I think so, but the problem is they could not run both simultaneously. My suggestion of putting the sim in a virtual machine would allow them to run side by side. (Provided you could find a PC that could handle it without screwing up your latency too much.)

I can't believe your comments, but I respect them. Thanks for them, I hope linuxcnc in the future the developers can give you a more professional approach.

It is very difficult to propose improvements

It is the second time that happens to me, the first one was with the tool radius compensation, what the developers say is fine, in cnc technology it is a big mistake, the compensation loses a segment of the trajectory at the entrance, and now this. The result is always a cheap alternative, not a professional one.

Thank you all, I will continue my way

Yes.
you can have many different machines on one pc. Or as many sim's as you like.
And if you want to have the machine working while you are testing something else, do it on a virtual box, as Todd mentioned.
