Arc output in NC w/mastercam

[zelaznog]

I'm having problems, I want I & J values instead of R value.
I'm using mastercam post processor, I can't find the "arcoutput$" value in my postprocessor file.

What mastercam version ?
What modified post ?
"arcoutput" should be found in the general output settings near the top of the PST file

looks something like this

breakarcs   : 0     #Break arcs, 0 = no, 1 = quadrants, 2 = 180deg. max arcs
arcoutput   : 2     #0 = IJK, 1 = R no sign, 2 = R signed neg. over 180

If version X or later
There is also an area in the MD ( Machine Definition ) file that requires setting, under "arcs"

PS: a mastercam forum exists, overseen by those working Mcam
you would get better / more responses asking the question there.

Thanks Superman,
I'm using McamX, there's no that line; i already checked that.

I'll post in MasterCam forum.

see the following code in post file

arctype$ : 2 #CD_VAR Arc center 1=abs, 2=St-Ctr, 3=Ctr-St, 4=unsigned inc.,
#5 = R no sign, 6 = R signed neg. over 180

and set it to 5

Try going to Settings at the top of the window, select "Control Definitions Manager". Select Arc under "Control Topics". Now in the box titled "Arc Center Type" make sure that the XY Plane, YZ Plane, and XZ Plane are set to "Delta start to center".


With this my .NC files look like this:
