Fanuc 0-M revision C Post processing issue

ronnieperrin — Wed, 16 Jan 2019 20:29:41 GMT

I am having 3 issues with the format of my post processing for a FANUC 0-M revision C when I use the Fanuc post process that comes with Fusion 360. I have copied the file and made a few changes already, but I am still running into 3 issues.

At the following URL (https://forums.autodesk.com/t5/fusion-360-computer-aided/post-for-fanuc-0m-problem-with-m06/td-p/5534368) it is mentioned that emails can be sent to cam.posts@autodesk.com to try to get resolution, but I have yet to get a reply email unfortunately.

at line 1156 of the new post processor that I created for my machine it used to create GCode in the format T? M06. I made th following changes and got the code to swap the M06 command and Tool#, but my first issue is my machine does not like the zero in the M6 command. The Gcode needs to read as such "M6 T?", but I cannot see where it is putting in the zero

line 1156
Original
writeBlock("T" + toolFormat.format(tool.number), mFormat.format(6));

Modified
writeBlock (mFormat.format(6),"T" + toolFormat.format(tool.number));

The second issue that I am running into is the machine does not like the use of parenthesie "( OR )".

The third issue I am running into is the machine does not like blank lines in the code. It seems after every tool change there is a blank line followed by a comment with parenthesie.

I have attached a picture in an attempt to clarify. I hope I have given you enough information.

Thanks for your time!

1st issue is easy

the zero padding is injected by the m format specification. fidn the line that looks like this

var mFormat = createFormat({prefix:"M", width:2, zeropad:ture, decimals:1});

and change it two this (note change to both width and zeropad)

var mFormat = createFormat({prefix:"M", width:1, zeropad:false, decimals:1});

issue 2:

the function shown below does the formatting of text, you can see the left and right parentheses hard coded in you can change them to whatever character your control requires (if you don't need the closing character then delete the + ")" altogether)

function formatComment(text) {
  return "(" + filterText(String(text).toUpperCase(), permittedCommentChars).replace(/[()]/g, "") + ")";
}

it looks like your control is using % for comments so the new code might look like this

function formatComment(text) {
  return "%" + filterText(String(text).toUpperCase(), permittedCommentChars).replace(/[()]/g, "");
}

Issue 3:

you can remove any possibility of generating blank lines by deleting any line in the post that reads as shown below.

writeln("");

You you can modify it to be a blank comment if you like the white space breaking up the g-code segments by changing the line to

writeln("%");
