Units of measurement Inch and mm

[JB69]

I hope someone can understand my question I don’t have all the terminology down.

The back story. Back in the beginning of getting my machine (Cross Fire Pro), I remember reading somewhere in the instructions that said to set everything up in Inches. Well, I did not do that. I wanted to work in mm. I know my Fusion is set up to default in mm. I am also aware that you can change that on the fly in Fusion.

I am having a torch height problem. I am struggling to understand post processing, and particularly the setup in Fusion. The section where you set the torch height. On that page, you can pick your measurement. But I think that when I pick mm, it is still asking for torch height in Inches. Is that correct?

So I guess I want to know is through the Post process, when entering the recommended values that Langmuir suggests do I need to convert the values given to mm, then add them or in the case of the torch height put it in inches. I am not sure when to do what. My logic said to convert. Also, are there settings in Fire Control for measurement that I am forgetting?

So did a sample mixing inches and mm. I first made the sketch in inches and midstream changed the units to mm. It seemed to make the switch appropriately.

Now I told Fusion to change my units to mm. Here is what happened:

I then went to Manufacturing and picked my tool, which is in inches. But when I got to the final page for Post Processing I told it I wanted mm.

In the Post Processing page, be sure to have the units in “millimeters”, notice that I still have the pierce height and cut height in inches.

Now look at the G-code. It has the metric determination of “G21” and Cut height and pierce height are reflecting metric numbers, not inches.

So it looks like it works pretty good.

Thank you for checking in on that. Very helpful.
