Fusion 360 Sinumerik 840D post - TRAORI Disable
Hello @Vohnsen
It can be done simply using your post, but here is the step to follow.
I selected and edited a machine configuration file, for example the Autodesk "Generic A axis". I copied it from the Fusion 360 library, into a local personnal folder in the "Machine Library".
When inside the personnal folder (local or cloud idem) i can edit it in order to ensure that the tcp option is unchecked.
Later on, i open the wcs definition to associate this machine with the setup.
When i post process, using the nc program, i can eventually force the machine selection there, if not done in the setup.
And the resulting nc code doesn't contains TRAORI, because my 4 axis machine defintion describe the kinematic and the machine capabilities correctly.
If you have your own machine defintion, just chek the first point.
Example output :
Cheers

Hi @Vohnsen
please find a quickly created machine file for this machine.
There is to options for the spindle speed 12000 or 15000, i have gone with the highest.
I can tell the direction of the fourth axis, so if it's rotating in the wrong direction, the orientation will need to be changed to a -1,0,0 from the actual 1,0,0.
Try this machine configuration file by associating it in the wcs definition, or the nc program, and don't hesitate to provide feedback.
The multi axis speed could also be changed from programmed feedrate, to degree per minute or inverse time feedrate (G93)
Regards.

Hello @toneanu_livia26,
the explanation provided above, was targeting a post modified in the last 6 months.
Your post had been modified 7 years ago by Autodesk; you can't expect to have the same functionality.
In order to implement this on your post you will need to change the following elements:
function onOpen() {
if (true) {
var aAxis = createAxis({coordinate:0, table:true, axis:[1, 0, 0], range:[-360.0001,360.0001], preference:1});
//var bAxis = createAxis({coordinate:1, table:true, axis:[0, 1, 0], range:[-120.0001,120.0001], preference:1});
//var cAxis = createAxis({coordinate:2, table:true, axis:[0, 0, 1], range:[0,360], cyclic:true});
machineConfiguration = new MachineConfiguration(aAxis);
setMachineConfiguration(machineConfiguration);
optimizeMachineAngles2(0);
}
The regular change is firstly the axis definition, informing the system that RTCP is not supported. (Page 7-174 in the actual revision of the manual)
var aAxis = createAxis({coordinate:0, table:true, axis:[1, 0, 0], range:[-360.0001,360.0001], preference:1, tcp:false});
Then we need to tell the post engine to ignore TCP optimization
optimizeMachineAngles2(2); // 2 instead of 0
Unfortunately, as the post if so old, other logic is missing, we will have to comment the TRAORI and TRAFOFF output.
//writeBlock("TRAORI");
and
//writeBlock("TRAFOOF");
In a more recent post, we would have had something like :
if (useTCP) {
writeBlock("TRAORI");
}
and we would have set the useTCP to false at the beginning.
Cheers

Try the attached PP, seems to be OK here but only you have the machine to test it 🙂 🙂 🙂
Might be a little closer, anyway, worth a try 🙂 🙂
If you mean the SUPA Home command then you can change that yourself at point of Posting in the "Post Properties", see image below to either a G53 or a Clearance option 🙂
Attached is a version of your Surub file done using the 2D Contour "Wrap" feature, the feed speed only changes when it does a Transition move, image below and G Code file also attached.
The G53 is a "Homing" move and the G56 you have is the WCS, not the same thing.
There is no reason I can think of why this would not run at your Machine if your 4th axis is set correctly at the machine. 🙂
