is there any way to block the operation of a machine with linuxcnc installed to be able to run a simulation of a program. could someone explain to me how, thank you very much.

I need to test the tool radius compensation on a lathe and I can't try several options to get the right one

When you start Linuxcnc from the menu, there are many sim configs already for many types of machines, choose a lathe and test.

hi tommylight .I know , but it is not what I need. on a machine with linuxcnc installed, I need to change run mode to simulation mode. is that possible ?

When a machine operator wants to try a program, how can he do it? I need to stop everything !!!

If you don't turn the drives on I'm pretty sure you can run it.

If you have homing switches you will need to hand trigger them.

I'm pretty sure I've done this with my parallel port machine. I don't think it will work if you have encoders or any feedback devices

Hi Leon82. Yes, I thought about it the same way, but there is a big problem, we are lying to Linuxcnc and he has control of the machine. You can do it, me too, but I need to let an operator work. and it is very dangerous on an installed lathe.

Are you talking about a gcode simulation?

Like camplete or vericut? They run the actual gcode file with a machine model

No, I am talking about how a machine with linuxcnc working, with all its settings, can simulate on its graphic screen the operation of the program without producing movement. Axis bases its GUI on a large simulation window, but can only display the simulation completed, or the simulation while a program is running. For an inexperienced operator who needs to test before executing (for example a tool radius compensation on a lathe). If the path to be generated is correct. This is very common to all controls, is this possible in LinuxCNC?

So like a machine lock button?

Gmocappy has an interesting feature where you can click the tool path and it will highlight the back plot

yesss !!! So like a machine lock button.!!!!. is this possible in LinuxCNC? .

like this for example in Halui. >

halui.mode.is-simulator
halui.program.is-simulating

and in simulator mode you can use the same program execution keys.

halui.program.run
halui.program.stop
halui.program.step
halui.program.resume

o for example in Axis

the button comand [simulator mode] and use the same program execution GUI keys.

is this possible ?????

Screw machines and fanuc has an option for manual handle retrace.

When you enter this mode the program will advance with the turn of the mpg wheel. If you turn it backwards the program will reverse. It comes in handy with 7+ axis machines where you have to program wait times for certain ops.

Quite the coding challenge I'll bet
