Perhaps expressed from my frustration during the short test I made. It isn't that hard, I agree. But as soon as the A axis had an angle, for example jogging in Z meant I got motion in Z, Y and A. I wasn't used to that and found it a bit surprising, but understandable after a bit of thinking. I think it is really good to be able to switch between the modes.

If one is comfortable with this, tcp is the easiest way to get g-code support from Fusion 360, just a few lines to change that reflects the 4 and 5 axis config.

Here's my version of linuxcnc XYZAC post processor for Fusion 360. Its based on tecno inverse time feed, Spangled 20190223 enable G64 path blending and also some code I stole from another post processor to Rewind C Axis since my setup is -10,+110 degrees in C.

Code:
if (true) { // note: setup your machine here var aAxis = createAxis({coordinate:0, table:true, axis:[-1, 0, 0], offset:[0, 0, 0], cyclic:false, range:[-10,110], preference:0}); var cAxis = createAxis({coordinate:2, table:true, axis:[0, 0, -1], offset:[0, 0.15, 0], cyclic:false, range:[-360000,360000], preference:0}); machineConfiguration = new MachineConfiguration(aAxis, cAxis); setMachineConfiguration(machineConfiguration); //optimizeMachineAngles2(0); // TCP mode enabled (eg. M128, TRAORI, G43.4, G243) optimizeMachineAngles2(1); // TCP mode disable (eg. M128, TRAORI, G43.4, G243) }

nice all axis videos show only the Iso cordinate flat system movements
no 5Axis syncron mode

will it be implemented in the post ?

Nice. I can see myself offering-up my spare harmonic drive mounting casting to my existing A axis tonight, and seeing if there are any more FHA drives on eBay.

Yes the post will handle 5 simultaneous axis just fine as will the machine. But I do have issues with the toolpaths generated by Fusion360 ... they are not clean - nothing to do with the post processor or machine. In the last video - part 5, the curved section is actually a Flow op so 5 axis simultaneous - I even made the remark that the toolpath is not clean. Also the op before the last of the same video - part 5 - is a simultaneous 5 axis op.

Thanks Andy - quite happy. Yes the FHA are like a perfect fit for 4th and 5th Axis.
