THC height issue in fusion 360

[Anonymous]

Hello everyone, before... I need to mention that I'm totally new in this field..... the post-processor I'm using is Mach 3... I prepared a simple model to cut but my THC is not lowering the height so the tool can cut but I can see it taking the path correctly without getting close to the stock. Here is the G code generated by Fusion 360 cam:

Hello @Anonymous 

i don't know which post you are using, but there is no z outputted in the gcode.

So the machine will never plunge in the part, that sure.

Try to edit the post, and look for a property enabling Z move.

Or check if in the onOpen function, there is a zOutput.disabled(); line.

For example in the mach3 plasma post, there is a property called useZAxis, and also another one called pierceHeight for defining the machine positionning in Z.

Regards.
