Post Processor for Yasnac LX3

[dbramley]

Does anyone have a post processor for Yasnac LX3 they would be willing to share? I bought a new to me Hitachi Seiki HT SII, and fusion does not have a post in its library. I have heard I can use a genetic haas post or Fanuc post with a little modification, but thought I would ask here first.

thank you,

Dan

Yasnak LX3, that's quite......dated. Out of curiosity, what year is the machine? (I only ask because my first mill had a Yasnak MX2 control, 1984 vintage)
Anyways, on to your question:
Do you happen to have any g-code that came with the machine? It's likely that the Fanuc turning post is going to be your solution, albeit with a handful of edits, as needed.

Hello @dbramley 

We have an hidden post for the Yasnac LX3.

Hidden mean that the post has not been tested on a machine yet.

It has been written based on the manual.

Here is the link to the post, if you are interested in testing it.

Please be careful when running the first program, and if it need refining, don't hesitate to provide feedback, or send a private message to improve the post processor.

Regards.

I would be interested in testing out this post.

I just bought a Hitachi Hitec 20 sii with the yasnac LX3 control, we are trying to get it up and going, this  would be really helpful.

bernesto1,

send me an email to dbramley@yahoo.com and I will give you the post I have. It is for a Hitachi Seiki HT20 so use at your own risk.

Hi @bernesto1 

for providing feedback, there are several ways of doing that.

If the post had been advertised, on the HSM Posts idea station, you can post in the corresponding thread.

If the link to the hidden post had been posted by an Autodesk employee, you can send him a private message via the forum.

Regarding the changes to the post, to stop the spindle at the end of the program, you can edit the onClose function:

function onClose() {
  previousToolingData = toolingData;
  writeln("");

  optionalSection = false;

  onCommand(COMMAND_COOLANT_OFF);
  onCommand(COMMAND_STOP_SPINDLE);  // new line added for spindle stop
  onCommand(COMMAND_STOP_CHIP_TRANSPORT);

then to stop the spindle when direction will change, edit this piece of code in the onSection function:

  // writeBlock(mFormat.format(clampSecondaryChuck ? x : x));

  var initialPosition = getFramePosition(currentSection.getInitialPosition());
  var spindleChanged = forceSpindleSpeed || newSpindle || isSpindleSpeedDifferent();

  if (!isFirstSection()) {  // start of new code
    // If spindle direction is changing, the spindle must be stopped first.
    if (!(currentSection.getTool().isClockwise() && getPreviousSection().getTool().isClockwise())) {
      onCommand(COMMAND_STOP_SPINDLE);
    }
  }  // end of new code for stopping spindle when changin direction

  if (insertToolCall || spindleChanged) {
    forceSpindleSpeed = false;

Regards
