Can I make a postprocessor for laser cutting in ArtCam, or Vectrics? What would the laser (which is connected to the PWM output of the spindle) be switched off at the time of transition?

I can not find a program in which you can generate the g-code for laser cutting.

There is really no difference between laser and spindle. They are controlled the same way.

[Anriro]

This is clear. But in the control program, the spindle turns on at the beginning, and turns off at the end of the whole program !!! But it is necessary that he turn on only when the laser approaches the desired cutting point, and turn off at the output of the part. Do you understand?

[PlanetCNC]

This is an easy change. I will make them for Vectric. ArtCAM software has been discontinued since 2018.

[Anriro]

When will he be ready? I did not find it in the new version of TNG.

[PlanetCNC]

Vectric Aspire v10.019 update which fixes some bugs was just released. It fixes some bugs in their postprocessor engine. I can start working on them now.

[Anriro]

Can you do it in artcam? this is done in 5 minutes.

[Anriro]

I did it myself, it takes even less than 5 minutes. I don’t understand what difficulties you had.

[PlanetCNC]

Main difficulty is, that ArtCAM is discontinued since 2018. I don't have it and it no longer exists.
But why are you asking me to do something that you can do yourself in 5 minutes?

[Anriro]

Because when I asked, thought it was difficult. And then I tried it and it turned out easy. True, I'm not sure that it will work correctly in 100% of cases.

In addition, you have written that MK3 / 4 can be used with a laser, although it is not written anywhere how to do it. Have to come up with something yourself.

[Anriro]

why does the speed of movement drop on command M3? the machine moves jerkily.

[PlanetCNC]

Check what script do you gave on your M3 command.

I just posted a video on Facebook showing my little DIY laser.

[Anriro]

Check what script do you gave on your M3 command.

I did not change anything, all the default settings. where to see this script?

[Anriro]

so with a stop at the M3 command do ??? or make a normal laser postprocessor.

[PlanetCNC]

M3 calls subprocedure which causes synchronization.
You need to remove those M3 commands from your g-code. They are redundant.
