With a Fadal 6030

When program is finished it wants to go to the work offset '0' before going to machine home.

The concern is the tool hitting any fixtures along the way.

It looks like the g28 code is telling it to jog around to the 0 position of XYZ of the work offset, then gradually make it's way to the machine home position.

What I'd like it to do is:

Program complete
Rapid Z to safe location
Turn off coolant and spindle
Then work it's way back to XYZ 0 of the home position.

(See code below) I've tried adding a couple of inches to the N85 Z position, but this causes Z to over travel and hit the limits when it finally makes it to 0 (as if it's adding those inches to the final Z position.

I've tried taking out 628, changing G90 to G91, changing the code to G0Z0H0,G0X0Y0, AND G91 H0 ZO.
E0 X0. Y0. I've tried all sorts of options, but nothing gets Z out of the way.

Once this is finally resolved, is there a way to add this to all programs, so that it doesn't have to be manually inputted for each program?

Thanks in advance for your help.

Hi,
I use Fusion but I use 'Clearance Hieght' in the post settings. That means the machine lifts up and out of the way when the part is finished, and that location is programmed
as part of the tool path. In my case I usually choose 50mm above the topmost of the part and or workholding.


You can use g28, g30....and they will eventually retract to machine home, but can and sometimes do take an intermediary step back 'into the danger zone'

If I'm not mistaken you can change that intemediary step, it is put ther by the post. If you edit the post you can change that location and thereafter all toolpaths will retract via the intermediate point
you have specified in the post..

I just realized I put this post in the CAD section and not the CAM section.

I just moved the post over there, to hopefully get some solutions to resolve the issue.

I have tried utilizing the clearance height however it still moves back over to the work offset before going to the machine home X0Y0Z0

Through trial and error, the G28 is what initializes that. Regarding your "intermediary step", even though I understand what you mean, I do not know where that is in the program, nor do I know how to find it within the software - assuming it is somewhere in the "post processing" section.
