Damn,
you're good!
Colin,
You've asked why the bad J value is comming out.
From the data you've provided, it appears your arc center output requires
signed incremental IJs. It also appears that the calculation for the IJs
in this case is being based on the previous arc rather than the current one.
This implies that the current position is not being updated properly for some
reason. I would check to see that the move to the new start point
is being properly output. If for some reason you are suppressing this
position from being output, you need to do a #UPDATE() on #XPOS & #YPOS
instead, so the system knows where to calculate the IJ vector from.
Hope this helps,

I posted
this question last week, but I don't think I explained it properly so here
goes. Looking at the attachment when I circ. interp. the 2 bottom parts
(horizontal m/c)the G02 line comes out : G02
I-.2985 which is fine. But when I circ. inter. the top parts the G02 line
comes out: G02 I-.2985 J5.0 which is not fine. If I did the top parts first
the G02 on the bottom parts will be: G02 I-.2985 J-5.0. Each part has its
own fixture offset(workplane). The "J" value seems to be coming from the the
top or bottom parts depending which I do first. My question is why is the
"J" value coming up. I hope
you can understand this. Thank You Colin
