Post Processing with multiple tools Bug

[lindseymd2020]

When I post process Multiple paths with the same tool everything works fine. When I post process with tool changes, the first path is 16" higher than the rest of the paths. Actually the first path is normal, then the remaining paths after the first tool change is 16" lower than Z0. I tried using a file that I had used before and it did the same thing. I had a friend test his also and had the same results now. This has just happened in the last couple of days. Attaching pictures the first picture show posting the paths together, then the other 2 pictures are posting them separately by tool.

Could you let me know what is the post processor you are using ? Is it a generic post form the library or the midfield version of the post ?

 But I have not changed or updated the Post Processor.

I'm sure it's not the post processor. As previously stated, I opened a file that I had used a few weeks ago (which worked then) and posted it using the same post processor that I used the first time and got the same results, first tool works, the rest of the tools looks like the Z is 16" to lower. Also, my friend that has the same problem is using a different file and also his machine is different from mine and using a different post processor. Seems like Fusion has a bug when posting with more than one tool. When every path is posted separately, everything is fine or if I post multiple paths together that use the same tool, everything is fine.

I don't think this is an issue in Fusion or the post processor. I tried a sample file that I had (with multiple tools) and then ran the code thru a backplotter (shows the paths and the code). Nothing is 16" above, everything is where it should be. Have their been any updates on the machine/control side of things?

Can you share your Fusion file and the resulting NC code here?

File > Export > Save to local folder, return to thread and attach the .f3d file in your reply, the NC file can be attached in the same manner.

My XYZ is set to the bottom of the stock. You can see after the first tool path (which is correct), the rest of them start way below the bottom of the XYZ.

[lindseymd2020]

Sorry, no there has been no updates in the machine, controller or the post process. Again I have a friend that has a different controller and post processor and he made a model from scratch and it did the same thing.

Okay, but your code shows this:

N25 S11025 M3
N30 G54
N35 G0 X7.6081 Y0.4041
N40 G43 Z4.7 H150     (Tool #150 is going to Z4.7")
N45 G0 Z3.6

N11105 T230 M6
N11110 S20000 M3
N11115 G54
N11120 G0 X0.6738 Y2.4648
N11125 G43 Z4.1 H230   (Tool #230 is going to Z4.1")
N11130 G0 Z3.08

N100700 T700 M6
N100705 S14000 M3
N100710 G54
N100715 G0 X2.1439 Y1.4115
N100720 G43 Z4.1 H700   (Tool #700 is also going to Z4.1"
N100725 G0 Z3.08

And your g-code looks like this:

I noticed that. I will look into it more. Thank you for your help.
