using canned text-lathe

[Mr. Dayshift]

Hi all,

 

Trying to determine if everything is set up right for using canned text 'parts chute'. Post file lists the function as supported and as Canned text #8=advance chute, #7 retract chute. When I open the canned text button for the part-off toolpath it list items 1101. through 1120. Items 1108(custom option is off) and 1107(custom option is on).

 

Is there a switch I need to turn on in the post?

Should canned text option field display #7 and #8 as per post features listing?

M codes are different than what I need, can I simply edit the words below for the right output M26 and M27?

 

#Chute M code selection

 

sm73 M73 #chute retracted

sm74 M74 #chute engaged

schute #target for string

 

Post is 'MPLMASTER'

Version X3 MU1

Fanuc series 0i-TC

 

Thanks in advance for any input here.

Editing the lines in your post ("M73" and "M74") to "M26" and "M27" should work to change your output.

 

Canned text is "on" by default, and you do not need to enable any switches to get this to work.

 

You may need to edit the text in the Control Definition, so the display will show up properly in the toolpath.

Colin,

 

Do you know how I can get canned text (M27 chute retract command) output at the end of the part off cycle? Is this the wrong application for using canned text?

[Colin Gilchrist]

Are you using the 'Cutoff' toolpath to do your partoff?

 

Canned Text is a very powerful tool, but it can be kind of tricky to use. The normal canned text options "Before", "With", and "After", are generally output before/after a toolchange, or "with" the entire operation.

 

For example, I created two lathe toolpaths, a basic 'Lathe Finish', and then a 'Cutoff' operation. I setup the Canned Text options to use "Parts Catcher Up", with an 'After' setting. Here are the results:

M27 <--  Wrong, because we want to retract at the end of the cutoff cycle

As you can see, the M27 command was output just after the toolchange/work offset lines.

 

If this is where you want the output, then great. But let's say for sake of example that you want the 'M27' in a different location in the toolpath. For that to happen, you need to use the Toolpath Editor function to insert Canned Text into the toolpath at a certain point.

 

In the example below, I setup the Canned Text in the normal Canned Text options to Advance the parts catcher at the beginning of the toolpath. Then I used the Toolpath Editor (right-click on the toolpath, select the Toolpath Editor option) to insert Canned Text at the very end of the toolpath to output the Retract for the parts catcher . This allows you to place the Canned Text output exactly where you want it (even in the middle of toolpath motion).

Note that when you use the Toolpath Editor, it will 'Lock' the toolpath operation, so make sure you've got everything setup correctly before you make the edits to insert Canned Text...

 

Hope that helps,

Colin,

 

Yes, I'm using cut off toolpath. I didnt realize there is canned text on the cut off parameters page of toolpath. I was using canned text button on tool path parameters page. I've almost got it right. I'm using custom construction and tool planes so when I move the canned text the point it goes wonky? Graphic shows tool off end of part and below centerline.

 

 

For now I'm using manual entry for chute retract after cut off toolpath, it's occurs as the last line the last event before M30.

Using Canned Text is either done in the Operation Dialog, or it is done through the Toolpath Editor. Explaining how to use the Toolpath Editor is a bit involved. I'll try and make a video that shows how to do this. It will be much easier than trying to write a description and posting screen shots...

 

Thanks,

 

Colin
