Geting ER20 this weekend - Is there any ADDON I could install on it?

[VRider75]

I had a anycubic I3 and back then I installed their smart filament detection thingy on it..

I know the ER20 has all that plus the BI touch autoleveling thing but .. is there any ADDON I can install on my printer for it to be ever more awesome?

Hi,
I restore your post because I want to tell other users:
There is an extension board so you can use the extra pin for the filament runout sensor.
