Trying to get my post processor setup for a siemens 828D/840D control w/ 4th axis rotary. The original post processor was outputting in cycle800 i have disabled that in the post processor and added my aAxis in the machine configurator portion and turned off the optimizeMachineAngles since i dont have TRAORI enabled on my control.
Doing the above gets my post to output as A=DC() movements, however my problem is that the Y and Z Axis is following the simulated tool tip in fusion 360, So as the simulation goes +/- around the part(instead of the part rotating) it outputs my G-code in the same way.
I have attached the post processor I've edited as well as the G-code that it output.
Im unsure if this is a post processor issue or a issue wit the control itself.
So I managed to get it working. I changed my setup WCS to be the center of the axis on the Z instead of off the top of the part like i was trying to do. Kind of strange I can't just choose the point I want and have the post figure it out off that point. Perhaps there is still something wrong with my post preventing it from doing that? But it is currently working so one step forward.
Now onto the fun of getting my motion more fluid, cause boy is it jerky.
Thank you.
Your post does what you tell him to. To work from the top of the part you need to work with the machine kinematics. This means that the machine has the exact poosition of the rotary and calculated coordinates upon rotation. Thats not standard functionality on a 4 axis machine, so for now: Part center
