4th axis, stumbling

Fueler — Fri, 05 May 2017 16:43:30 GMT

First try at 4th axis.

I got the design cammed out properly..... or so I thought.

When I went to post it I got the following

Your post is not set up to use a 4th axis rotary.

I suggest checking out this thread on how to get it set up properly: https://forums.autodesk.com/t5/hsm-post-processor-forum/how-to-set-up-a-4-5-axis-machine-configuration/td-p/6488176

If you haven't done any post editing, please give this thread a thorough read: https://forums.autodesk.com/t5/hsm-post-processor-forum/getting-started-modify-posts/td-p/6371381

You can also attach your post here, someone can probably do this for you if you are uncomfortable doing any of the edits yourself.

Thanks Neil,

I will read up as soon as my eyes can focus again. Just got back from the eye doctor.

I was looking around for something along those lines. Like everything else it is tough to find.

If if was not for this place and youtube I don't know if I would ever figure out this stuff on my own.

Using that info I managed to get 360 happy. Will do a ghost run in the morning to see where I stand.

Thanks again

Awesome! Let us know how it goes. 👍

Did not make it too far.

Centroid choked on line 16. stating 501 invalid character.

It highlighted the last 0 as the offender.

Any thoughts?

16: N55 G0 A270. C0.

Re: 4th axis, stumbling

Fueler — Sun, 07 May 2017 02:47:48 GMT

Did some sluething. I THINK that the offending C0 is really about the C.

A is my rotary. I changed the C to A and it went on by that line and choked on the next position that happened to be C180.

Which means there are a fair amount of Cs I need to change. bummer

I assume this means I need to change something in the Centroid post or the centroid parameters.

In my centroid post I believe this is the parameters I need to change to get the A axis active. But Which?

function onOpen() {

if (true) { // note: setup your machine here
var aAxis = createAxis({coordinate:0, table:true, axis:[1, 0, 0], range:[-360,360], preference:1});
var cAxis = createAxis({coordinate:2, table:false, axis:[0, 0, 1], range:[-360,360], preference:1});
machineConfiguration = new MachineConfiguration(aAxis, cAxis);

setMachineConfiguration(machineConfiguration);
optimizeMachineAngles2(1); // map tip mode
}

if (!machineConfiguration.isMachineCoordinate(0)) {
aOutput.disable();
}
if (!machineConfiguration.isMachineCoordinate(1)) {
bOutput.disable();
}
if (!machineConfiguration.isMachineCoordinate(2)) {
cOutput.disable();
}

Ok, talked myself though it enough to make it work.

This line needed the last part change to a axis only.

machineConfiguration = new MachineConfiguration(aAxis, cAxis);

New line

machineConfiguration = new MachineConfiguration(aAxis);

Ghost run looks ok. Will go live in the morning.

function onOpen() {

setMachineConfiguration(machineConfiguration);
optimizeMachineAngles2(1); // map tip mode
}

Having it like below works as well

function onOpen() {

if (true) { // note: setup your machine here
var aAxis = createAxis({coordinate:0, table:true, axis:[1, 0, 0], range:[-360,360], preference:1});
//var cAxis = createAxis({coordinate:2, table:false, axis:[0, 0, 1], range:[-360,360], preference:1});
machineConfiguration = new MachineConfiguration(aAxis/*, cAxis*/);

setMachineConfiguration(machineConfiguration);
optimizeMachineAngles2(1); // map tip mode
}

Dan,

Sounds Like you are on the right track, but just in case, and for anyone else searching centroid here is a functional 4 axis post for Centroid. As always proceed with caution, this post works flawless on my mill but yours may be different.

It's block delete what means anything between */ /* will not be read, I knew you would know it's for others if they did not know you can just use // or */ /* in the post processor instead of deleting what's not needed.

Good morning,

I tried this post in my hsm software and it doesn't work.

I tried to modify the post according to the directions posted here and it works, however its posting the c axis rotation in the output file.

What am I missing here.

I have been in evaluation mode here for some time and the only eval software that works with 4 and even 5 axis is mastercam. Any ideas?

Thanks,

Chris

You have the setup done wrong, you have the wcs done wrong in the toolpaths, the post processor is set wrong many things could be wrong.

You will need to post the post processor you are useing and an model
