Mixed up tools and height offsets

I noticed today that I was getting a mixed tool number and height offsets. I get a T2 H3 then a T3 H2. Obviously this wont work. The code calls the correct tool number then on the next line calls for another tool. The problem is generated during the post process from fusion 360. I'm using the Centroid post processor. Anyone have any idea what I may have set wrong? I did verify that in the setup the tool number does match the offset. I'm attaching an example of the code.

Line 30 T2 M6 is the tool change command and line 35 T3 is the next tool command for auto tool loader if one exists. As far as Fusion and your CNC controller are concerned the tool in use is tool 2.

Thanks breezy.

Looks like I should look for a setting in the centroid control then.

If your machine's control does not support "pre-call" of the next tool, it really shouldn't matter. I'd "guess" that lines 35 and 115 would just be ignored.

If the post you're using works perfectly as far as movements and cutting, you may be able to edit the post so that it doesn't create the pre-call lines.

Thanks for the help guys. I did some experimenting today. My machine does not support precall I don't have a tool changer. Too much $$$ for me at this point. I deleted the precall lines 35 and 115 and it works as it should. I'll look in fusion and see if there is something I can turn off to make it work. If not I'll manually edit it out.

Its solved. I went into the Fusion 360 post processor for centroid and turned off the "preload tool" option. It no longer outputs the extra tool command. Since I already manually deleted the lines I know it will now work. Thanks again for pointing me in the right direction.
