Need a little G-Code/UGS help

[merkidemis]

So I have a G-Code file I am trying to send to engrave some text, however it only ever does the last character, then stops. The file is thousands of lines long, but it only ever seems to send the first 640 or so.


Starts out fine:
%

(Header)

(Generated by gcodetools from Inkscape.)

(Using default header. To add your own header create file "header" in the output dir.)

M3

(Header end.)

G21 (All units in mm)



(Start cutting path id: path4303)

(Change tool to Cylindrical cutter)



G00 Z 5.0000

G00 X 197.0722 Y 66.6195



G01 Z -1.5000 F 100.0000(Penetrate)

G01 X 197.6751 Y 71.6235 Z -1.5000 F 1600.0000

G02 X 197.8079 Y 71.7393 Z -1.5000 I 7.3906 J -8.3442

G02 X 197.9419 Y 71.8524 Z -1.5000 I 7.1967 J -8.3887

G02 X 198.0777 Y 71.9635 Z -1.5000 I 7.0363 J -8.4702 
...

And then gets to this section:
G01 X 197.0722 Y 66.6195 Z -2.5000

G00 Z 5.0000



(End cutting path id: path4303)





(Start cutting path id: path4303)

(Change tool to Cylindrical cutter)



G00 Z 5.0000

G00 X 197.6148 Y 61.0729



G01 Z -1.5000 F 100.0000(Penetrate)

G02 X 197.2166 Y 60.6457 Z -1.5000 I -36.2539 J 33.3917 F 1600.0000
G02 X 196.8249 Y 60.2355 Z -1.5000 I -33.8307 J 31.9090

G02 X 196.4281 Y 59.8301 Z -1.5000 I -32.4768 J 31.3892

G02 X 196.0378 Y 59.4414 Z -1.5000 I -30.2538 J 29.9847
...

And stops right after it does the G01 command and never runs the G02s. Here is the verbose output from UGS Platform 2.0 nightly from 8/3:

>>> G03X196.9589Y65.4248Z-2.5000I-1247.5657J119.4843

Why isn't it running the next set of commands?  I have tried removing the () lines and the blanks because I am not doing tool changes, but it always stops at the same spot.

I don't use inkscape but I seem to remember people having lots of issues with the code it generates and ugs/grbl.

Oh now I noticed it. Arcs. Those I and Js are the issue. Arcs do not play well with GRBL. That was the problem with inkscape.

[Derek the Admin]

It's not so much the arcs themselves, but how it specifies the arcs. There are different ways to specify an arc and some won't be acceptable to by grbl. Can you post the entire file as an attachment? When it skips the command it doesn't report what it was.

Also, have you looked at your sender settings to see your line length maximum? You should set it to 70 if you haven't already. It might be skipping commands that are longer than the max setting that's in there now.

[merkidemis]

It was the line length 70 thing. I didn't throw an error while running, but did when I tried to reconnect. I didn't see it earlier because I would close the app and power down the CNC after each attempt. Disconnecting and then reconnecting showed the error message. Thanks for your help!

[Derek the Admin]

Glad that helped.

Always forget about that line length thing.

[Derek the Admin]

Ya, it's one of those things that you don't know about until it bites ya.I think it's got us all once.

[miro]

where is the sender setting window to set the line length to 70 in UGS 2.0?
I cannot find it for the life of me and I bet its right in front of my face..
