I’m using Fusion360 and trying to cut through a 3/4" MDF (19.05mm) But In the early gcode i see N40 G43 Z15 H1 N45 G0 Z1 N50 G1 Z-0.365 F2032 … N17885 X279.85 Y65.894 Z-20.05 [Select_Tool_and_QTView__3_Browser__1__and_Autodesk_Fusion_360] The offset for the tool is 1 But what is weird is …

Hey Mark @markalanevans , hey Alex @suprak , G43 takes optional H argument with tool number, but without H uses last tool selected with Tx M6. I tried to reproduce it by using: G21 G10 L1 P1 Z12 ; set 12 mm tool length offset for tool 1 T1 M6 G43 ; select tool 1 and switch on tool length offs…

Z movements (like X and Y as well) are in reference to your zeros (what you probed/set). I do not believe that any other tool table related values have any impact.

So does that mean the post processor is messing up? I don’t understand why it’s saying to cut down to 20.05.

Where did you set your zero in F360?

I set my zero at the top of the model.

The G43 command by itself will use the offset in the tool table, which I believe is unsupported - or at least it’s not documented where to put it on the controller. You could attempt to use the G43.1 command to set a dynamic offset value but that won’t come from Fusion with the current post process…

Ughhh. The origin was set to Stock Box Point… Instead of Selected Point on model :man_facepalming: Thank you. That looks like it has fixed it.

Mark, I’m not sure if anyone helped you understand the Fusion 360 post screen you first showed. Those are all register numbers. Number is the tool number in the code as in T1 ← this in unsupported on the 1F so is not needed but harmless as far as i have seen. Length offset is to set register the…

THank you! THat is very helpful. I really appreciate it.
