Gantry action post carve

Is there a way to choose what the gantry does at the end of a carve?

Ours travels to XYZ home. I would like it to just raise up to Z home and stop.

@AkaMrBill What machine do you have? Do you have limit/homing switches? What code sender are you using?

AltMill 4x4.

Integrated bump stop switches.

gSender 1.5.6.

@AkaMrBill One way would be to edit your post processor to remove the G0X0Y0 line that likely appears at the end.

Thanks, I will look into that.

We are using Fusion 360 for post. It may have options for that as well.

I will let you know what I find.

@AkaMrBill For giggles, I just looked at a grbl post for Fusion360. It’s like nothing that I’ve ever seen before. :grinning_face: I’m used to the very simple posts that Vectric uses.
I’m sure that there is something in your post that is returning the machine to XY0. It’s just that I can’t pretend to know what that is.

Yep, I can’t speak g-code worth a crap either. The files produced by Fusion are SUPER Detailed. So digging through them can be a bit overwhelming, editing them is almost dangerous for me. But hey, got to learn one of these days.

I have at least one more run to do today. I’ll see what I can figure out and post back here when I do.

Sorry for the delay in replying.

By removeing these two lines of code,

G28 G91 X0 Y0
G90

the Z rises up, the spindle stops, and the program ends, just as desired.

Now, if I can just find a way to get Fusion to not add them would be ideal.

If you are using VCarve you can edit the code for the machine driver (Gcode) so that when the G code file is generated it will do what ever you have edited for it to do. This what I put at the end of my inch and mm .pp files. It shuts down the spindle first, then moves to the machine home as I want the machine to move out of the way of what it just carved and away from me. ( I got 11 stitches when I failed to move my hand fast enough when it was returning to just X0, Y0 with a still spinning bit).

@kimsey.pollard He is not using VCarve. He is using Fusion360.

As it turns out, if you configure your bits in your tool library in Fusion 360 as “Manual tool Change”, the Z raises up, the spindle stops, and the program stops.

This is exactly what I was looking for.

Cool, didn’t know that. Thanks for posting that tidbit!
