Do I put the #update in the @arc
section?
Thanks, Colin
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,

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 Williams
