2.5 axis controller , how to make cam only move in 2 axis per command line

[zebb.guy]

Hi is there a way to make fusion 360 manufacture only move 2 axis at the same time for older controllers?

for example, i can use parallel but then i have to set direction to one way in passes 

otherwise i will actually do 3d machining which is what i have selected but I'm trying to avoid. 

is there anyway apart from what im already doing to only move 2 axis at the same time in the command line ? 

so rather than trying to move x y and z it will only move two axis per line ?

Hi @zebb.guy 

there is no automatic way to do this in Fusion.

As you have already found, the only way to achieve this is to manually set the parameters to avoid helical plunge,

Try to select unidirection toolpath, i.e parallel unidirectionnal and so on.

Regards

I'm a beginner with modding PPs - just curious if my idea would suite to this issue??

just for example the linear motion, because its easy to change..

lets say you start with this code

here is the PP part that is in charge of that NC code output

and you break it up into two lines of code like that,

you end up with this code output,

that would at least help @zebb.guy so his machine only moves with X&Y or with Z or I'm wrong on this ?

Hi @florianD8LYR 

You are wrong.

Ignoring a value, is unsafe, as the tool had to move in this position.

It's better, but surely not simpler, to force the toolpath to move along basic directions.

For example when doing a parallel toolpath, it MUST be along X or Y. And not along exotic angle, 20, 35, 45 degree.

Doing vertical ramp, then a planar lead in and lead out...

oh dam* it - now it lights up,..   for sure you are right, because then the machine would first move in XY then in Z and thats a totally different movement
