Spindle orientation M19

[Anonymous]

Hello,

I am using the EMC post, for "Fine boring - shift" the orientation command needs to be M19 R followed by a degree value.

The EMC post provides only  M19.

Can anyone  please tell me which parameter contains "Spindle shift orientation"?

(I figured out "Boring Shift" is contained in "cycle.shift")

Thank you, best Regards

Hi @Anonymous,

It looks like the generic EMC post processor does not support a Fine Boring canned cycle.

For the orientation to work however it looks as though that code will need to be added from a parameter output by the CAM operation:

258: onParameter('operation:shiftOrientation', 180)

For that you would need to use a getParamter and create a variable to hold that value. Since the default behavior requires the toolpath to be output as an expanded toolpath I believe this will have to be added to the COMMAND_ORIENTATE_SPINDLE code under the onCommand section.

Do you know what the code needs to look like in this case? I know for a Haas it could be M19 P180. or M18 R180. for instance.

Hi Steinwerks,

thank you very much for your support.

At first I tried:

var ori = 180

if (mcode == 19) {
writeBlock(mFormat.format(mcode), "R"+ori);} else {writeBlock(mFormat.format(mcode)); }

This works fine ==> G Code: M19 R180

Then I tried :

var ori = getParameter("operation:shiftOrientation", 180); as  suggested which leads to an error:

Mismatching number of arguments for invocation of 'unsupported PostProcessor.getParameter(string) const'.

var ori = getParameter("operation:shiftOrientation")

Error: Parameter does not exist.

Please tell me, what I did wrong.

Thank you,

best regards

Sorry, this took me a while to get right. I wanted to make sure that if the spindle orientation offset was zero it wouldn't output a value, so here's what I came up with. Under the onCommand section you can add this line of code, for which the orientation will only take place for a Fine-boring cycle. I don't know of any other cycles offhand that utilize spindle orientation but if any are developed (IE probing) this may have to be altered to suit. I tested this with a fine-boring cycle with an offset of 180 and zero. As always, test carefully!

  case COMMAND_ORIENTATE_SPINDLE:
	if (cycleType="fine-boring"){
		var spindleOrientation = (getParameter("operation:shiftOrientation"));
		if (spindleOrientation > 0){
			writeBlock(mFormat.format(19) + " R" + (xyzFormat.format(spindleOrientation)));
		} else {
			writeBlock(mFormat.format(19));
		}
	}
	return;

 Here's the code it generated (.F3D file attached as well):

Good to hear!

I'm pretty syre the code could be simplified but this was the most straight-forward and understandable solution I think.
