This has been a tough learning experience for us, just as we think we're making progress booom here we go again... The cutter is going along a straight line cut and just turns right into our part. We redid the post file (made a few changes) this time it went past the same spot without crashing, but it crashed again in another spot! This time I called tech support who back plotted our post and could not find a problem, looked at our model and could not find a problem, simulator does not show the problem. Afterwards we went through the lines and found this:
N5218 G00 Z.1
N5219 X3.1336
N5220 Z-.93
N5221 Z-1.04
N5222 G01 Y3.2282 F20.
N5223 X3.1351 Y3.2279
N4777 G02 X3.2758 Y3.1567 I-.1438 J-.4971
N4778 G02 X3.3169 Y3.1271 I-.3138 J-.4787
N4779 G02 X3.509 Y2.7276 I-.3191 J-.3994
N4780 G02 X3.509 Y2.7276 I-.5113 J0.
N4781 G01 Y2.726
N4782 Y-2.7263
N4783 Y-2.7275
N4784 G02 X3.4943 Y-2.8495 I-.5149 J.0001
N4785 G02 X3.4128 Y-3.0263 I-.4996 J.1232
N4786 G01 X3.4127 Y-3.0264

Raised the Z axis (to clear the tool) and ran this section of code, sure enough it did a whoopi doo just like it was told to.

We are using centroid_m400_rev2.millpst

What could cause it and how do we fix it? We are behind the 8 ball on this job and desperate for a solution. Attached is the full post, Thanks to the users and support found here.

I'll assume your talking about this crop circle here?



I'de need your bbcd file and the post processor your using attached here to see why that was output.

[BAMCNC.COM]

I've found that certain settings in CAM do things like this, entry, exit, cut connections, layer clean up, etc.. try doing a basic program, no frills as it were and see what happens.

Thank you for the reply, I'm having trouble uploading zip files bare with me

under posting tab see what the arc fit tolerance is set at
if set to less than .001, set to .002 or greater
i use .005 , this is roughing, and leave a little more for finish cut
i do lots of surfaces and get this often

test before putting to part, a slight gap in a corner of the surfaces will do this , and hard to find

preditor will most of the time show this crop circle

First time to use this let me know if it works...

If it asks for a pass: NBUSAPS

[wmbeau]

This is the post processor we use

[BurrMan]

If you set line 221 to "no", then the crop circle will not show up in the second feature, advanced rough finish pass....

Can your controler accept the code without the arcs broken at quads? The only way i can get it to work with that enabled, is to drop the arc fit to .001....

[wmbeau]

It's working! Changes arc Fit to .002 and line 221 to N

We are cutting now, will update at the end of the day.
Again, my thanks
