Okuma Post Mods

[gmdimarzio88]

Fo those looking for a good Okuma post here's one I edited to have HA instead of H# values. G116 toolchanges, and table forward at the end of the program which I set to G30 P11. You can set that P value to anything besides P1. The Okuma guys told me to just avoid the first page of home positions so P1 doesn't accidentally get overwritten, so that's why it's P11. The G82 dwell time is also now functioning correctly. It could use some tweaking since I'm no expert, but it works well.

Hi,

Thanks for that, I have changed my post as in your attachment to move my table to the door G30P30 but it moves the table to the door after every operation rather than just at the end of the program.

Any help would be much appreciated.

error(localize("Bad axis specified for writeRetract()."));
return;
}
}

if (words) {
gMotionModal.reset();
if (properties.useG16) {
writeBlock(gFormat.format(16), hFormat.format(0), gMotionModal.format(0), words); // retract
} else {
writeBlock(gMotionModal.format, "G" + "30" + " P30");
}
}
zOutput.reset();
}

function onClose() {
writeln("");

onCommand(COMMAND_STOP_SPINDLE);
setCoolant(COOLANT_OFF);
onCommand(COMMAND_UNLOCK_MULTI_AXIS);

writeRetract(Z);

gAbsIncModal.reset();

if (machineConfiguration.isMultiAxisConfiguration()) {
setWorkPlane(new Vector(0, 0, 0)); // reset working plane
}

// writeRetract(X, Y);

forceXYZ();
gAbsIncModal.reset();

onCommand(COMMAND_END);
}

Thanks

I'm not sure how to only have it at the end. Whenever I tried to have this ONLY at the end, I get an error when posting. I'd love some help with this as well. I don't need the machine to go home between each work offset just at the end.

[bob.schultz]

It looks like you added this code to the writeRetract function, which is called at the end of each operation.  You can move this code to the onClose function, which is only called at the end of the program.  Also the format of your code is not correct and should have generated an error.  See the correct format below.

function onClose() {
  writeln("");

  onCommand(COMMAND_STOP_SPINDLE);
  setCoolant(COOLANT_OFF);
  onCommand(COMMAND_UNLOCK_MULTI_AXIS);

  writeRetract(Z);
  writeBlock(gFormat.format(30), "P30");

  gAbsIncModal.reset();

That worked. Thank you very much.

[gmdimarzio88]

Thank you. Finally got it working right.

I have a question If I may I know this topic is a few versions back. The format that we use for the G116 macro is G116 PT=1 PQ=2 (PT is current tool PQ is preload)

we have them all on the same line so that the variables are passed through to the macro. 

I wrote the below code for the stock post and it works well as long as we don't try to use the same tool in multiple toolpaths. Once we try to use it in multiple toolpaths it gives an error that the nextTool is undefined.  This adds a check box incase someone doesn't want to use either the HA/DA or the G116 and will just do the default as well. Am i trying to make this overcomplicated or am I just missing why it thinks on repeat tool numbers it doesn't think the previous variable is undefined.

Thanks in advance

I cannot duplicate this issue in Fusion with your post, but if you are getting an undefined nextTool variable, you can protect against this by using a command similar to the following.

  var nextTool = isLastSection() ? getSection(0).getTool().number : getNextTool(); // returns the first tool as the next tool when the last tool is loaded

[rslay_57cadcam]

I added that line and I still get the failed. Here is the error and what that section looks like in the output.

I am using the Post processor Benchmark v1 file to test. With these settings checked

Thanks for the help in narrowing this down.

[rslay_57cadcam]

I fixed the issue it was a curly brace that was out of alignment.

Thanks for the assist again all
