I also found this website that shows a setup and some general info about what he did to accomplish his setup. I have requested the parts list that he ordered from 80/20. And since his setup is similar to mine as well as the same width, I will probably build this one. I have the extended Z-axis as well. He describes his process of machining, and he is using a 3+1 setup to essentially do 4 sided machining. But I would like to take advantage of Fusion 360s ability to do simultaneous machining. Vectric Aspire as well. And that might be the best way for me to get the types of models carved out anyway. But I will get to that once I figure out the Fusion setup.
Can anyone point to or provide any information on setting up a post processor for Fusion 360 and simultaneous 4th axis machining on the CNCRP? I have the 4896 pro. It would be great to get a modified cncrp post processor. I have no idea what is going on inside of those. I am sure I could learn it, but time is hard to find. And with how cheap these 4th axis setups can be had for, the CNCRP community needs this in the post processor anyway. The axis I bought is a 100:1 harmonic drive, not that it matters for the post processor, I think Mach will be where I set that all up.
Fusion does not have simultaneous 4th axis machining at all it will have continuous what is coming soon, I think you are thinking of wrap what's wrapping a toolpath by substituting A for X or Y there is a hack for it to cut in a continuous fashion.
Getting the 4th axis to work in fusion is easy you just make sure you are useing the latest post and if it does not post out a A axis move it's simple to turn it on
it's in this section
function onOpen() {
if (properties.useRadius) {
maximumCircularSweep = toRad(90); // avoid potential center calculation errors for CNC
}
if (true) { /*set this to true to turn on A. B or C axis set it to false to turn it off*/
var aAxis = createAxis({coordinate:0, table:true, axis:[-1, 0, 0], cyclic:true, preference:1});
machineConfiguration = new MachineConfiguration(aAxis);
setMachineConfiguration(machineConfiguration);
optimizeMachineAngles2(1); // map tip mode
