How to Output EOB On Every NC Line

bigjohn · May 10, 2013

G'day

I'm trying to program a small Roland four axis router using MC. The control needs the NC file to have every line ending With the ASCII characters EOB (end of block). Alt69 Alt79 and Alt66 generate the EOB code, but I cannot get any post to output the code. I know I can easily use the editor to replace the code I'm getting now, (Euro sign or a square or an upside down L), but I would like to get the post to do the job. I will not be operating the machine.

I'm getting this:

%€

I have tried to trick the post. I've tried MCX3 and MCX5 The parameter in the control definition accepts ASCII from 0 to 255

Guys Can this be done?

Create a string variable;

seob : "EOB" # EOB callout string #note you need minimum two spaces between "seob" and :

Add "seob" every where needed;

plinout #Output to NC of linear movement - feed

if feed = 0, test_feed = mprint(sfeedrate0)

pcan1, pbld, n$, sgfeed, sgplane, `sgcode, sgabsinc, pccdia,

pxout, pyout, pzout, pcout, `feed, strcantext, seob, e$ (<<<<<<<<<<<<<<<<<<<<<<<<<<<,

plinout example;

Tim, Thank you for your answer. In your sample EOB has been added only to the G01 move lines. The control will error if the ASCII characters EOB are missing from any line.

I've been trying for about two weeks before posting here, I have asked some computer programmer friends, no luck.

The easy way is to use the editor to replace whatever symbol I get as carriage return with the ASCII 69 79 66, without spaces. I still think there must be another way.

bigjohn · May 12, 2013

Please see the picture.

I typed the ASCII value of E in the first box and O in the alternate box. Now I got EO at the end of every line. How do I get the B if there are only two boxes to type in.

I'm buggered.

Help, please!

John,

I would just uncheck the alternate EOB character box and do it "the hard way". I only made the changes as shown to my post and only changed plinout for demonstration purposes so I wouldn't have to remove "seob" 500 times after the posting.

To add it to your post just use the search & replace function of your editor.

After adding the variable, search for ", e$" and replace it with ", seob, e$" (with the assumption that you have spaces between the [are they called arguments?])

First make a copy of your post especially before making a mass modification like this.

Mick from CNC Software Inc. · May 13, 2013

The simplest approach is to run a Replace regular expression in your text editor, for example in the X7 code editor open the file and add the following expression (?<!\))$ in the replace dialog using the appropriate settings.

The expression will ignore commented lines and append a space + EOB to each line.

bigjohn · May 14, 2013

We haven't got X7 editor. I've been doing the replacement in the editor, which, as you, Mick, said is the easy way, however I would prefer the post to generate a finish NC file. I don't know who is going to run the machine in the future and make a mes out of the NC file in the editor.

Sorry if I'm fussy.

I'll try Tim's suggestion.

Thanks mates.

bigjohn · May 16, 2013

Hi Tim

I tried very hard to do it your way. I did not win. I do not know what I'm doing any more. Error file was the largest I've ever seen. "Illegal character", "Label not defined". Deleted everything and opted for the easy way instead.

John,

did you ever try to take a file from that machine and open it with a hex editor?

I never heard of Alt69+Alt79+Alt66 as EOB marker before.

It's more likely that the 'EOB' is displayed simply as placeholder for some non-standard ASCII character.

Figure that out and the alternate EOB character method is your friend again.

Good luck

Thomas

bigjohn · May 17, 2013

G'day Thomas,

No, I have never tried and don't have a hex editor. That is a good suggestion and I'm going to try it. What editor would you recommend?

Of course you've never heard of Alt69+Alt79+Alt66. I have tried so many things and done lots of research trying to output EOB at the end of NC lines, and that is one of the combinations I tried in the post. If EOB is missing from any line the control will error.

Some years ago another engineer and I wrote a post where ";" was needed as end of block. Here is the code with the AXCII value for ";" in a MCV8.1 post, then updated to VX2 and later to Vx5.

This section of the post is no longer in the Xposts unless the old post is updated to X.

Thanks for your suggestion

John

Got it. Finally I got the post to generate "EOB" on every line of the NC file. It wasn't easy but I'm glad I didn't give up.

Got a Hex editor from the net but did nothing for me apart from learning a little more code.

I took the bull from the horns and did some manual pasting of the code 69,79,66, on every occurrence of pbld, n$, like this: changed e$ for 69,79,66, e$. and then used the debugger to fix the errors. I got a space separating the digits E O B. I don't think it's an issue. I may find another separator instead of (,).

I have to give credit to Tim Johnson for I used his way a little but not exactly.

Thank you all who help and read this thread and did not get board with it.

John

Tim Johnson · May 19, 2013

I'm glad you got it John.

For the spacing issue (if it ends up as a problem);

69,no_spc$,79,no_spc$,66,e$

bigjohn · May 20, 2013

I canceled the spaces in the CD and is posting fine.

Thanks mate. Owe you a beer.
