Cannot set auxiliary digital output with cutter ..

Hi,
somewhat connected to my question here:
www.linuxcnc.org/component/option,com_ku...0/lang,english/#9800
I have the following question: When I have G41/G42 on and try to switch on a digital output (M64 P01) I get the following error message:
"Cannot set auxiliary digital output with cutter radius compensation on". But I would like to
So, is there any way to configure EMC2 to allow this? And why is it impossible in the first place?

regards
frankbatzen

Thanks for your help, John.
However, with M62/M63 I'm just getting another error message: "Cannot set motion output with cutter radius compensation on"
It would seem strange to me if EMC2 really did not allow switching the digital output on with cutter radius compensation on. Don't people normally use the digital outputs while milling?

regards,
