Hi everyone
Excuse me for my late response.
I didn't change anything at all like the firmware
It's trying to connect.
where I should have the indications of ambient temperature it shows 0 °C ( nozzle and bed ). And I noticed that the nozzle is getting hot.
It makes the usual "bips" when I touch the screen, it is not mounted on a case yet.
I don't know which versions of the firmwars I have on both screen and card.
It is a 4 pin cable.
Thanks again for your support.
