Error Code 243 Bad Number ?

[Rocko1]

I had an issue this morning with a error code on our Haas VF3 #243 (bad number) pop up but not in the same spot on some code our CAM program created. I looked at the code and :
G0Z-.2
Y4.1889
G1Z-.465F15.
G3Y4.1502Z-.4666K-.4688F50.
G1Y4.1394Z-.4676
Y4.1374Z-.4679
The text that is in bold was highlighted on the screen where the program stopped. I cannot see anything wrong with the code? What else can cause this problem. I am DNC'ing from a computer under 6 feet away. Thanks

That code looks a bit strange.. Not sure what your trying to accomplish with it. Are you trying to move in a YZ arc? If so, then you should have G19 enabled (moving in the YZ plane) then your code should be something like G3 Y4.15 Z-.4666 Jxxx K-.4688 Where J would be the distance along the Y axis to center of the circle, and K is the distance along the Z axis to center of the circle.

Read up in the haas manual on how the G02/G03 commands work, and also about the G17,G18,G19 plane specifications.

I was outputting the code in arcs instead of smoothed line segments via gibbscam. ALso yes it was withing the yz plane. There must be something in the control on the cnc possibly that does not like the tolerance. It will run for about 10 minutes then stop. I finally gave up and switched the output code to smoothed line segments. The code gets bigger and is not quite as smooth tool path but it has not stopped yet. What are your thoughts?

I'm guessing your doing some fine intricate 3d profiling with arcs that small. I still say that the problem is that the J isn't being introduced into the mix, but I could be wrong. The manual does say that it is 'optional'.

Could be tolerances. Are you using cutter compensation? I've found that with doing 3d cutting, it is almost imperative that I program to the size of the cutter.

tnik,
Thanks for the help. I will have to do a little digging on the post processor since it seems that it will post code on arc tool paths (3d) that perhaps cause a problem for the CNC sometimes.
