How can i change my live tooling S code? PostProcessor

[mxdawg121]

We have a Swiss lathe here, with a mitsubishi m800 control. Quite the funky control when it comes to gcode. The live tooling requires an M113 S3=2000 , to turn on the live tooling. Is there a quick way to edit the post to make it S3=2000 instead of S2000

Im using a doosan lathe post currently , its the closest thing i have to a working post, and it required a bit of tinkering to work. This is one of the last things i have left to make this a mostly working solution until a post is made for this machine.

Also getting way undersized radius's when im doing a helical interpolation on the live tooling side. Any input there would be much appreciated.

Hello @mxdawg121 

Search at the beginning of your post for the line:

var sOutput = createVariable({prefix:"S", force:true}, rpmFormat);

Add another line :

var s3Output = createVariable({prefix:"S3=", force:true}, rpmFormat);

This will define a specific formating when outputting the spindle speed for the live tools.

We now need to instruct the post to use this formatting when needed.

When we are using the sOuput variable, we may need to alter the code as in this modified function

function onSpindleSpeed(spindleSpeed) {
  if (rpmFormat.areDifferent(spindleSpeed, sOutput.getCurrent())) {
    writeBlock(
machineState.liveToolIsActive ? s3Output.format(spindleSpeed): sOutput.format(spindleSpeed));
  }
}

Depending if the section is using a live tool or not we switch the format used.

Below in the code,

In the StartSpindle function:

  writeBlock(
    gSpindleModeModal.format(spindleMode),
    machineState.liveToolIsActive ? s3Output.format(spindleSpeed): sOutput.format(spindleSpeed));
    spindleDir,
    spOutput.format(getCode("SELECT_SPINDLE", getSpindle(TOOL)))
  );

In the StopSpindle function :

After the sOutput.reset();,

Let’s add another line with

S3Output.reset();

Regards.

I hacked out pieces from the post I sent you and put them in this.

Thanks guys, both of those worked. It works perfect now!

Ah, guess I spoke a little too soon. 

with the first method, it won’t apply the prefix to the first live tooling operation , but will with the following live tooling operations. Does it check if it’s live tooling after declaration of prefix?

could this be modified to check before deciding which prefix to use on the first live tool operation?

the second method works as expected except the post thinks a static drill is a live tool. The way I read it is, is turning tool true/false then {  the drill isn’t considered turning tool, or live tool from what I gather. 

could this be modified with an or statement? Tooltype drill || turning?

I just tried the post I attached and it worked fine. Are you sure the hole you're drilling is on center? Check your setup.

This is what it outputs on my end - 

M8

2000 M113

G0 C0.

missing prefixes on all the spindle lines it appears

Can you attach the F3D file.

I see, maybe i didnt have the correct post loaded. but i just loaded it. Seems like it puts s3= for everything - live or not. something easy to fix?

And your getting regular Scodes on turning ops and S3=codes on live tools? ugh what am i doing wrong here. Im a mill guy, just got throw onto a lathe. a swiss nonetheless.

This is the program it's spitting out.

I feel your pain. I'm a standard lathe guy that got thrown a Swiss and it's still a headache.

Do you have axial live tools on this machine?

If so, I'd ditch that deburr toolpath, model a chamfer on that end and use blend. Multi-axis feedrates are almost always wrong in the base post processors. It took me hours of work to get them corrected in my Swiss post.

[mxdawg121]

okay, so your getting the same thing i am. The regular operations should be standard m3's and they all come out in the live tool format

[BrandonTBFBF]

What do you mean "standard M3s"? I'm seeing M3 for all the turning operations and the static drilling operation. The live tools are using M113.
