RichAuto A11E - Interpolateorg. c:107

Greetings!
I'm borrowing my friends router to do some hobby CAM stuff. I have designed and generated process with Fusion 360. I'm posting .tap files, selected Mach3 type for this machine. It has RichAuto A11e.

Everything has been fine until recently when I started getting error: "../zwork/zarch3d interpolateorg. c:107"
This happens when I'm doing cam with 3D pocket clearing. I have to clear pocket of 5cm in depth, sometimes this error occurs on 3cm heigh, or 4cm heigh. I'm cutting my guitar neck out of 5cm thick wood block.

I tried searching for error codes and explanations why this happens but Google didn't give me anything.

Maybe someone here could help me figure out what am I doing wrong.

Cheers!
