G03 turn wrong way

kristercnc

In some of my programs G03 turns the wrong way and creates a big circle insted of a small radius.
How do I upload the G-code and pictute of what the machine does with it.
I tested the G-code in NC Viewer, and it lookes good.
G-code is made in Cambam 1,0.
The problem is the same from drawings from nanoCad 5 and Incscape.
I have run several G-code that works, in the past.

try   G91.1

I have now tried ESTLCAM. If I use I/J codinates are relative, it works. G91.1 (G90 is also there) is then added to the code. If I leave it in the code, the CNC goes wild.
But if I delete G91.1 from the code, everything works OK. At least so far.
In CamBam there is not any options (that I know of). It uses I/J for radius (and G90). In the last program I ran only 1 of many G03 went wrong. In Mach3 I never had any problem.
