Heidenhain "Angle Reference Missing" error

[Lugy]

Hi all, I've just loaded a program into an old Bridgeport Interact 412 running Heidenhain TNC 151, that I created using Mastercam.
I've come across an error while trying to do a 26x6mm slot, using a 6mm cutter (set to 5.98mm diameter). When it gets to line 54 I'm met with the error "Angle Reference Missing".

I'm not too familiar with Heidenhain programming to be able to see what's wrong, any programs are made using Mastercam and I'm used to Fanuc .

Can anyone shed any light on this for me please? Is it because the cutter rad is so close to the slot rad?

Hi Lugy,

Did you manage to find a solution to this problem?
I am having a similar problem; it stops at line 140 (code is below) with same error/warning message: "Angle Reference Missing". Any help would be appreciated
