update to 2.9 went wrong

Hi Everyone. I updated my Linuxcnc from 2.8.4 to 2.9.1 but my setup (in gmoccapy) doesn't work anymore. I updated as per instructions and ran my ini as before but I guess I am either doing something wrong or I missed something. Attached is the report that I got.

Could someone please point me to a right direction. Many thanks.

2.8 uses python 2.7 whereas 2.9 uses python 3.

you need to look at /home/frezar/linuxcnc/configs/PrintNC/python/toplevel.py and related files and adapt or replace them with those from 2.9.

Thank you. I did what you suggested before writing here but maybe I made a mistake somewhere... Let me try again.

I tried again and it works just fine.
